    FROM THE CIRCUIT COURT OF FREDERICK COUNTY
    William W. Eldridge, IV, Judge
    (Jason E. Ransom; Ransom/Silvester, on brief), for appellant.

    Rebecca M. Garcia, Assistant Attorney General (Jason S. Miyares,
    Attorney General, on brief), for appellee.
    While investigating a public-indecency complaint, the sheriff’s deputies here spoke with
    appellant Dana Mark Camann, Jr., in the parking lot of a convenience store. During that
    encounter, one deputy noticed that Camann was hiding something under his shoe and told him to
    move his foot. Camann did so, revealing aluminum foil with burnt residue and a straw. The
    deputies arrested Camann and searched his person, discovering a white powder in a cellophane
    wrapper in his wallet and pills in a pill bottle in his pocket. Testing of the white powder revealed
    that it contained two controlled substances: fentanyl and etizolam. The pills tested positive for
    two other controlled substances. Camann was convicted of three felony counts of possessing a
    Schedule I or II controlled substance and one misdemeanor count of possessing a Schedule IV
    controlled substance, all in violation of Code § 18.2-250.
    *
    Pursuant to Code § 17.1-413, this opinion is not designated for publication.
    We reject Camann’s argument that the trial court erred in failing to grant his motion to
    suppress the evidence.1 While we agree that a Fourth Amendment seizure occurred when the
    deputy told Camann to move his foot, the directive was part of a lawful investigative detention
    that was supported by reasonable suspicion. Upon discovering the burnt residue on the
    improvised smoking device that Camann was hiding, the deputies had probable cause to arrest
    him for drug possession. They then conducted a lawful search incident to arrest, discovering the
    narcotics that he was convicted of possessing.
    We agree with Camann, however, that there was insufficient evidence to support his
    conviction for felony possession of etizolam.2 While Code § 18.2-250 permits a defendant to be
    convicted for knowingly possessing a controlled substance without knowing which controlled
    substance he has, it does not impose strict liability for each subsequent controlled substance that
    may be found in the mixture. Because the Commonwealth failed to prove that Camann knew
    that the white powder in his possession contained more than one controlled substance, we
    reverse his conviction for possessing etizolam.
    BACKGROUND
    After 1:00 a.m. on September 10, 2020, Deputies Spears and Russell of the Frederick
    County Sheriff’s Office responded to a report of a man masturbating outside a 7-Eleven
    convenience store. When Deputy Russell arrived, Camann was standing on a sidewalk in the
    parking lot, with his back against the side of the store.
    Deputy Russell was the first on the scene. Deputy Spears arrived soon after, and his
    body-camera footage was introduced into evidence. Deputy Russell conversed briefly with
    Camann before entering the store to interview the customer and employee who had reported the

    incident. While Deputy Russell was inside, Deputy Spears engaged in “normal small talk” with
    Camann before telling him why the police had been called. Camann denied any wrongdoing and
    continued to stand in place. Deputy Russell returned, telling Camann that witnesses claimed to
    have seen him masturbating.
    Camann reacted indignantly, but as he shifted his weight back and forth, Deputy Spears
    noticed that Camann appeared to be hiding something under his left shoe. After Camann moved
    his foot enough to offer a glimpse of the aluminum foil underneath, Deputy Spears said, “move
    your foot, move your foot.” Camann did so, revealing a blue plastic straw and a piece of
    aluminum foil with burnt residue. From his training and experience, Deputy Spears knew that
    people commonly “use aluminum foil and plastic straws” to smoke narcotics. Upon seeing the
    burnt residue on the aluminum foil, Spears decided to arrest Camann.
    After placing Camann in handcuffs, Deputy Spears read him his Miranda3 rights and
    subsequently searched his pockets. Spears found more foil and a straw, similar to what Camann
    had been hiding under his foot, a cellophane wrapper in Camann’s wallet containing a white
    powdery substance, and pills in a pill bottle.
    Subsequent testing revealed that the white powdery substance was a mixture of fentanyl,
    a Schedule II controlled substance, and etizolam, a Schedule I controlled substance.4 The
    mixture weighed 0.056 gram. One pill in the pill bottle contained amphetamine, a Schedule II
    controlled substance; another contained clonazepam, a Schedule IV controlled substance.5 The
    aluminum foil and straw that Camann was hiding under his shoe were not tested for narcotics.
    The grand jury returned four indictments against Camann: three felony counts of possessing a
    3
    Miranda v. Arizona, 
    384 U.S. 436
     (1966).

    Schedule I or II controlled substance and one misdemeanor count of possessing a Schedule IV
    controlled substance.
    Camann moved to suppress the evidence, claiming that the search and seizure violated his
    Fourth Amendment rights. The trial court denied the motion, finding: (1) the interaction between
    Deputy Spears and Camann began as a consensual encounter; (2) Deputy Spears’s asking
    Camann to move his foot was “not . . . an order” and was “not a seizure”; (3) there was no
    expectation of privacy in the “public area” beneath Camann’s foot; (4) there was probable cause
    to arrest Camann after seeing the straw and aluminum foil with burnt residue; and (5) the drugs
    in Camann’s pockets were legally discovered as part of a search incident to arrest.6
    At the jury trial that followed, the Commonwealth’s evidence consisted of Deputy
    Spears’s testimony, his body-camera footage, and a certificate of analysis detailing the results of
    the lab tests on the drugs found in Camann’s possession. The court denied Camann’s motion to
    strike the Commonwealth’s evidence. Camann then testified. He admitted that he was a drug
    addict, that he had tried to conceal the foil underfoot, that the foil contained “a drug,” and that
    the items found in his pockets were all his. He admitted knowing that the white powder was
    fentanyl but denied knowing that it also contained etizolam, a drug he’d never heard of.
    The court denied Camann’s renewed motion to strike the etizolam charge. Relying on
    Sierra v. Commonwealth, 
    59 Va. App. 770
     (2012), the court held that Camann “b[ore] the risk
    . . . of punishment for whatever substance was there.” Over Camann’s objection, the jury was
    instructed that “[t]he Commonwealth [wa]s not required to prove that [Camann] knew the
    precise substance he [wa]s alleged to have possessed, only that he knew the substance was a
    controlled substance.” In closing, the prosecutor argued, based on that instruction, that “You
    don’t need to know whether it is heroin or fentanyl or etizolam or cocaine or anything else,

    amphetamines, meth. As long as you know that you are possessing something illegal you are
    guilty of every one of those things . . . .”
    The jury convicted Camann on all four charges. Although the original indictments did
    not identify the specific drug involved, the verdict form signed by the jury foreperson correlated
    the drugs to the indictments: CR21-213 (amphetamine); CR21-214 (fentanyl); CR21-215
    (etizolam); and CR21-216 (clonazepam). The court entered judgment on the jury verdict and
    sentenced Camann to two years’ incarceration with one year suspended for felony possession of
    amphetamine, two years with two years suspended on each of the felony convictions for
    possessing fentanyl and etizolam, and 180 days with 180 days suspended on the misdemeanor
    conviction for possessing clonazepam. Camann noted a timely appeal.
    ANALYSIS
    Camann challenges the trial court’s denial of his motion to suppress and the sufficiency
    of the evidence to support his felony conviction for possessing etizolam.
    A. The trial court did not err in denying the suppression motion (Assignment of
    Error 1).
    Camann argues that the trial court erred in denying his motion to suppress the narcotics
    seized from his wallet because the search of his wallet was not supported by probable cause.7 If
    a person is “illegally seized within the meaning of [the] Fourth Amendment . . . any evidence
    derived as a result of that seizure [i]s subject to suppression under the exclusionary rule.”
    Watson v. Commonwealth, 
    19 Va. App. 659
    , 662 (1995). “The exclusionary rule operates not
    7
    Camann’s assignment of error relates only to the narcotics seized from Camann’s
    “wallet”—the fentanyl and etizolam. The assignment of error omits any reference to the pills
    found in the pill bottle. Accordingly, this appeal involves no challenge to Camann’s convictions
    for possessing amphetamine [CR21-213] and clonazepam [CR21-216]. See Rule 5A:20(c)(1)
    (“Only assignments of error listed in the brief will be noticed by this Court.”); Riddick v.
    Commonwealth, 
    72 Va. App. 132
    , 146 (2020) (stating that an appellate court “cannot ‘consider
    issues . . . not encompassed by [the] assignment of error’” (quoting Banks v. Commonwealth, 
    67 Va. App. 273
    , 290 (2017))).

    only against evidence seized and information acquired during an unlawful search or seizure but
    also against derivative evidence discovered because of the unlawful act.” 
    Id.
     (quoting Warlick v.
    Commonwealth, 
    215 Va. 263
    , 265 (1974)).
    “When challenging the denial of a motion to suppress evidence on appeal, the defendant
    bears the burden of establishing that reversible error occurred.” Street v. Commonwealth, 
    75 Va. App. 298
    , 303-04 (2022) (quoting Mason v. Commonwealth, 
    291 Va. 362
    , 367 (2016)).
    “Appellate review of a suppression ruling involving a Fourth Amendment challenge presents a
    mixed question of law and fact.” Id. at 304 (citation omitted). “‘This Court is “bound by the
    trial court’s findings of historical fact unless plainly wrong or without evidence to support
    them.”’ ‘However, the Court reviews de novo the overarching question of whether a search or
    seizure violated the Fourth Amendment.’” Moreno v. Commonwealth, 
    73 Va. App. 267
    , 274
    (2021) (citation omitted) (quoting Williams v. Commonwealth, 
    71 Va. App. 462
    , 475 (2020)).
    “[O]ur review includes evidence presented at both the suppression hearing and the trial.” 
    Id.
    (quoting Williams, 71 Va. App. at 475).
    “Police-citizen confrontations generally fall into one of three categories.” McGee v.
    Commonwealth, 
    25 Va. App. 193
    , 198 (1997) (en banc). All three types occurred in this case.
    “First, there are consensual encounters which do not implicate the Fourth Amendment.” 
    Id.
    Camann admits that his encounter with the deputies was consensual up until Deputy Spears told
    him to move his foot. Second, “there are brief investigatory stops, commonly referred to as
    ‘Terry’ stops, which must be based upon reasonable, articulable suspicion that criminal activity
    is or may be afoot.” Id.; see Terry v. Ohio, 
    392 U.S. 1
    , 27 (1968). We conclude in the first
    section below that Deputy Spears’s statement to Camann to “move your foot” transformed the
    consensual encounter into an investigative detention. But Spears’s directive was a minimal
    imposition on Camann’s liberty, and it was supported by reasonable suspicion that Camann was
    -6-
    engaged in criminal activity. The third type of encounter involves “‘highly intrusive, full-scale
    arrests’ or searches which must be based upon probable cause to believe that a crime has been
    committed by the suspect.” McGee, 25 Va. App. at 198 (quoting United States v. Sokolow, 
    490 U.S. 1
    , 7 (1989)). We conclude in the second section below that Spears’s discovery of the burnt
    residue on the improvised smoking device that Camann was hiding under his shoe gave Spears
    probable cause to arrest Camann for possessing a controlled substance.
    1. The deputy’s request for Camann to move his foot was an investigative
    detention supported by reasonable suspicion.
    The admissibility of the narcotics ultimately found in Camann’s pockets depends on
    whether Deputy Spears’s telling Camann, “move your foot,” constituted an illegal seizure.8 To
    answer that question, we must consider (1) whether Camann was seized at all when Deputy
    Spears told him to move his foot and, if so, (2) whether the seizure was an investigatory
    detention, for which reasonable suspicion was required, or an arrest, which would have required
    probable cause. McGee, 25 Va. App. at 198. Camann argues that he was seized because Deputy
    Spears’s words signaled to him that he was not free to leave.
    8
    The Commonwealth misplaces its contention that Camann had no reasonable
    expectation of privacy in the discarded foil under his shoe. The Commonwealth likens what
    happened here to searching the garbage left for the trash collector in a public place, which is not
    forbidden by the Fourth Amendment. See California v. Greenwood, 
    486 U.S. 35
    , 40-42 (1988).
    The Commonwealth contrasts that scenario with searching someone’s shoe while the person is
    wearing it, where a reasonable expectation of privacy attaches. See Sheler v. Commonwealth, 
    38 Va. App. 465
    , 477-78 (2002). While Camann argued in the trial court that Deputy Spears’s
    telling him to move his foot was both a search and a seizure, he pursues only the seizure claim
    here. In other words, Camann does not argue that the space under his shoe was illegally
    searched; he claims that his person was illegally seized when Spears told him to move his foot.
    “The right to security in person and property protected by the Fourth Amendment may be
    invaded in quite different ways by searches and seizures. A search compromises the individual
    interest in privacy; a seizure deprives the individual of dominion over his or her person or
    property.” Horton v. California, 
    496 U.S. 128
    , 133 (1990) (emphases added). At this step of the
    inquiry, we evaluate whether Camann’s person was illegally seized, not whether the space under
    his foot was illegally searched.
    -7-
    We agree that Camann was seized when Deputy Spears told him to move his foot, not
    because Camann was not free to leave, but because a reasonable person in Camann’s position
    would not have felt free to keep his foot planted. “Only when the officer, by means of physical
    force or show of authority, has in some way restrained the liberty of a citizen may we conclude
    that a ‘seizure’ has occurred.” Terry, 
    392 U.S. at
    19 n.16. A seizure ordinarily occurs when “a
    reasonable person would have believed that he was not free to leave.” Piggott v.
    Commonwealth, 
    34 Va. App. 45
    , 49 (2000) (quoting United States v. Mendenhall, 
    446 U.S. 544
    ,
    554 (1980)). But “when the person . . . has no desire to leave, the degree to which a reasonable
    person would feel that he or she could leave is not an accurate measure of the coercive effect of
    the encounter.” Florida v. Bostick, 
    501 U.S. 429
    , 435-36 (1991). Rather, “the appropriate
    inquiry is whether a reasonable person would feel free to decline the officers’ requests or
    otherwise terminate the encounter.” 
    Id. at 436
    .
    Camann wanted to remain where he stood—he wanted to keep his foot firmly planted.
    We must therefore ask whether a reasonable person would have felt free to remain where he
    stood after Deputy Spears said, “move your foot.” The Commonwealth argues that we are bound
    by the trial court’s finding that Deputy Spears’s statement was a request, not a demand. Even if
    it was a request, however, the relevant inquiry is the effect of that request on a reasonable person
    in Camann’s position. It is not dispositive that the statement might not have been an order. The
    question is whether a reasonable person would have felt “free to decline the officers’ requests.”
    Bostick, 
    501 U.S. at 436
    .
    We conclude that a reasonable person in Camann’s position would not have felt free to
    defy the deputies by keeping his foot planted. Camann had a wall at his back and a deputy on
    either side of him. The deputies told him that he had been accused of masturbating outside the
    7-Eleven. “[W]hen a police officer confronts a person and informs the individual that he or she
    -8-
    has been specifically identified as a suspect in a particular crime which the officer is
    investigating, that fact is significant among the ‘totality of the circumstances’ . . . .” McGee, 25
    Va. App. at 200. That revelation can “‘convey a message that compliance with their requests is
    required’ and ‘that failure to cooperate would lead only to formal detention.’” Id. (first quoting
    Bostick, 
    501 U.S. at 435
    ; and then quoting United States v. Berry, 
    670 F.2d 583
    , 597 (5th Cir.
    1982)).
    We disagree with the Commonwealth that Camann “voluntarily moved his foot in
    response to the request.” Camann’s movement was not “voluntary” because a reasonable person
    would not have felt free to decline Deputy Spears’s request. That Camann instantly complied—
    even though he did not want to—suggests that he thought he had to. Under the circumstances,
    that was a reasonable conclusion. The “seizure of a person requires either physical force by the
    police officer or, ‘where that is absent, submission to the assertion of authority.’” Beasley v.
    Commonwealth, 
    60 Va. App. 381
    , 392 (2012) (quoting California v. Hodari D., 
    499 U.S. 621
    ,
    626 (1991)). Camann submitted to the deputy’s authority here.
    We must next determine whether that seizure was made during an investigative detention
    or an arrest, for that characterization determines the level of suspicion required to justify the
    deputies’ actions. McGee, 25 Va. App. at 198. “An investigatory stop is permissible under the
    Fourth Amendment if supported by reasonable suspicion,” Ornelas v. United States, 
    517 U.S. 690
    , 693 (1996), while a warrantless arrest requires probable cause to believe that a crime has
    been or is being committed, see Cromartie v. Billings, 
    298 Va. 284
    , 300 (2020). The Supreme
    Court of the United States has recognized the “difficult line-drawing problems in distinguishing
    an investigative stop from a de facto arrest.” United States v. Sharpe, 
    470 U.S. 675
    , 685 (1985).
    There are no rigid time limitations on investigative detentions or bright-line rules for evaluating
    whether a seizure is an investigatory stop or a de facto arrest. 
    Id.
     The “scope of the intrusion
    -9-
    permitted [during an investigatory stop] will vary” with each case. Florida v. Royer, 
    460 U.S. 491
    , 500 (1983). “The test is whether the police methods were calculated to confirm or dispel
    the suspicion quickly and with minimal intrusion upon the person detained.” Washington v.
    Commonwealth, 
    29 Va. App. 5
    , 15 (1999).
    Applying that test, we find that Deputy Spears’s request that Camann move his foot was
    part of an investigative detention, not an arrest, because it was a minimal intrusion upon
    Camann’s liberty. Camann did not have to move from where he was standing on the sidewalk of
    the convenience store, let alone leave the premises. Deputy Spears’s suspicions would have been
    confirmed or refuted in an instant by Camann’s simply moving his foot an inch or two in any
    direction. Such a minimal intrusion on liberty is the hallmark of an investigative detention.
    To justify telling Camann to move his foot, therefore, Deputy Spears needed only
    “reasonable, articulable suspicion that [Camann was] engag[ed] in, or [wa]s about to engage in,
    criminal activity.” Turner v. Commonwealth, 
    75 Va. App. 491
    , 500 (2022) (quoting McGee, 25
    Va. App. at 202). “The requisite level of belief, when calibrated to reasonable suspicion, is less
    than probable cause, less than a preponderance, and certainly less than beyond a reasonable
    doubt.” Hill v. Commonwealth, 
    297 Va. 804
    , 817 (2019). A reasonable suspicion must not be
    “‘the product of a volatile or inventive imagination’ or one ‘undertaken simply as an act of
    harassment.’” 
    Id.
     (quoting Terry, 
    392 U.S. at 28
    ). “In reviewing whether an officer possessed
    reasonable, articulable suspicion sufficient to justify a seizure, a reviewing court must consider
    ‘the totality of the circumstances—the whole picture.’” Mitchell v. Commonwealth, 
    73 Va. App. 234
    , 247 (2021) (quoting Sokolow, 
    490 U.S. at 8
    ).
    Deputy Spears had reasonable suspicion to tell Camann to move his foot. Camann was
    standing in place, noticeably keeping his left shoe planted as he shifted his weight back and
    forth. Deputy Spears could see a piece of aluminum foil sticking out from beneath Camann’s
    - 10 -
    shoe. Through his training and experience, Spears knew that aluminum foil is often used with a
    straw to smoke narcotics. Although Spears did not at first see the straw or the burnt residue, a
    police officer in Deputy Spears’s position could form a reasonable belief that Camann was
    engaged in criminal, drug-related activity and trying to hide the evidence. Thus, Deputy Spears
    had “more than a hunch”; his suspicion “flow[ed] reasonably from articulable facts.” Asble v.
    Commonwealth, 
    50 Va. App. 643
    , 648 (2007). What is more, the reasonableness of Spears’s
    suspicion was corroborated by Camann’s admission at trial that he was “intentionally hiding
    what was under [his] foot” because he “knew it was a drug and . . . knew that it is illegal to
    possess drugs.” We thus conclude that the investigatory detention that occurred when Deputy
    Spears said “move your foot” was properly supported by reasonable suspicion.
    2. The deputies’ discovery of burnt residue on the improvised smoking device
    Camann was concealing gave them probable cause to arrest him for
    possession of a controlled substance.
    We agree with the trial court that the deputies’ discovery of what Camann was hiding
    under his foot gave them probable cause to arrest him. “Probable cause exists when the facts and
    circumstances known to the officer ‘are sufficient to warrant a person of reasonable caution to
    believe that an offense has been or is being committed.’” Park v. Commonwealth, 
    74 Va. App. 635
    , 646 (2022) (quoting Al-Karrien v. Commonwealth, 
    38 Va. App. 35
    , 47 (2002)). “This is an
    objective standard that focuses on the totality of the facts and circumstances. It involves a much
    lower evidentiary standard than proof beyond a reasonable doubt.” 
    Id.
     (citation omitted).
    In assessing probable cause, “we must consider what the ‘totality of the facts and
    circumstances’ would have ‘reasonably meant to a trained police officer.’” Curley v.
    Commonwealth, 
    295 Va. 616
    , 622 (2018) (quoting Jones v. Commonwealth, 
    279 Va. 52
    , 59
    (2010)). That “includes, of course, an officer’s ‘common-sense conclusions about human
    behavior.’” Id. at 623 (quoting Dist. of Columbia v. Wesby, 
    138 S. Ct. 577
    , 587 (2018)).

    Though an officer’s “[s]ubjective intentions play no role in ordinary, probable-cause Fourth
    Amendment analysis,” Whren v. United States, 
    517 U.S. 806
    , 813 (1996), “a police officer may
    draw inferences based on his own experience in deciding whether probable cause exists,”
    Ornelas, 
    517 U.S. at 700
    .
    When Camann moved his foot, Deputy Spears discovered a straw alongside the
    aluminum foil that Camann was concealing. As Spears testified and as the body-camera footage
    showed, the foil contained burnt residue. As noted above, Deputy Spears testified that, based on
    his “training and experience,” it is common for people to use aluminum foil and a plastic straw to
    smoke narcotics. To a layperson, those items might seem like litter, but to Deputy Spears, whose
    testimony about his “training and experience” we must give “due weight,” Ornelas, 517 U.S. at
    700, they reasonably suggested drug possession.
    Finding burnt residue on an improvised device for smoking narcotics created probable
    cause to believe that Camann was in possession of a controlled substance. We have held (and
    our Supreme Court has affirmed) that “the finding of white powder residue on a cut-off straw by
    an officer experienced in investigating crimes involving narcotics is sufficient to constitute
    probable cause”—in that case, probable cause to justify a warrantless search of the defendant’s
    vehicle. Carson v. Commonwealth, 
    12 Va. App. 497
    , 503, aff’d en banc, 
    13 Va. App. 280
    (1991), aff’d, 
    244 Va. 293
     (1992).
    We also found the appearance of drug residue sufficient to constitute probable cause in
    Commonwealth v. Ramey, 
    19 Va. App. 300
    , 304 (1994). The police officer there found the
    suspect in possession of an improvised smoking device—a plastic bottle covered with foil that
    was punched with holes—and the foil had “carbon burn marks on it.” Id. at 301. “Because of
    the officer’s experience with drugs, the bottle appeared to him to be a homemade ‘bong’ used for
    smoking illegal drugs.” Id. “The officer seized the device and arrested the defendant, who was
    - 12 -
    later charged with possession of cocaine because of cocaine residue on the foil.” Id. at 302. We
    held that the officer had probable cause to seize the device despite that he could not determine
    what drug had been smoked. Id. at 304. “Because of the distinctive character of the plastic
    bottle with foil on top and the highly unlikely event that it would have a legitimate use, the
    officer had probable cause to believe that the ‘homemade bong’” was evidence of a crime. Id.
    (emphasis added).9
    In short, since Spears had probable cause to arrest Camann for possession of narcotics,
    “the subsequent search” of Camann “was a lawful search incident to arrest under the Fourth
    Amendment.” Perry v. Commonwealth, 
    280 Va. 572
    , 582 (2010). The trial court thus
    committed no error in denying Camann’s motion to suppress the evidence.
    B. The evidence did not support the etizolam conviction (Assignment of Error 2).
    Camann also assigns error to the trial court’s refusal to grant his motion to strike the
    Commonwealth’s evidence on the etizolam charge. He argues that, for a defendant to be
    convicted of two felonies for possessing a single mixture containing two different controlled
    substances, the Commonwealth must prove that the defendant knew that the mixture contained
    more than one controlled substance. We agree.
    9
    Courts in other jurisdictions have likewise found that the discovery of drug residue on
    the defendant’s person or on a narcotics pipe found in the defendant’s possession provided
    probable cause to arrest the suspect for possession of a controlled substance. See State v. Rose,
    
    282 P.3d 1087
    , 1093 (Wash. 2012) (en banc) (finding probable cause for a warrantless arrest “for
    possession of a controlled substance” when the officer “had a plain view of a glass pipe, with a
    white residue inside, that in his training and experience he suspected were consistent with drug
    possession”); People v. Edwards, 
    925 N.E.2d 576
    , 577 (N.Y. 2010) (“Because drug residue was
    first seen [on the defendant’s hand] while the police had a justifiable basis to continue the
    detention for the traffic infraction, that observation provided probable cause to arrest and search
    defendant.”); Bright v. State, 
    455 S.E.2d 37
    , 52 (Ga. 1995) (“The officer’s subsequent
    observation of a crack pipe and of crack cocaine residue on the pipe was probable cause for the
    arrest for possession of a controlled substance.”).
    - 13 -
    1. Code § 18.2-250 requires knowing possession for each count charged.
    Mens rea means “[t]he state of mind that the prosecution, to secure a conviction, must
    prove that a defendant had when committing a crime.” Mens Rea, Black’s Law Dictionary (11th
    ed. 2019). The term is often used interchangeably with “scienter.” E.g., Esteban v.
    Commonwealth, 
    266 Va. 605
    , 606-07 (2003); Maye v. Commonwealth, 
    213 Va. 48
    , 49 (1972)
    (per curiam).
    In interpreting the mens rea element required to convict for drug possession under Code
    § 18.2-250, we do not write on a clean slate. We held in Sierra “that the plain language of Code
    § 18.2-250 requires a defendant to know that the substance he possesses is in fact a controlled
    substance, but that it does not require him to know precisely what controlled substance it is.” 59
    Va. App. at 775. Thus, if a person thinks he has heroin, but it turns out to be fentanyl, that
    person has still “knowingly or intentionally . . . possess[ed] a controlled substance.” Code
    § 18.2-250; Sierra, 59 Va. App. at 783-84 (“A claim by a defendant that he knew he was
    possessing a controlled substance, but was unaware or mistaken as to the precise identity of that
    substance, is not a defense under Code § 18.2-250.”).
    We have also held that a defendant who possesses multiple caches of the same controlled
    substance can be convicted of only one violation of Code § 18.2-248, which prohibits possession
    with intent to distribute, unless the Commonwealth can prove “separate intents” respecting each
    cache. Lane v. Commonwealth, 
    51 Va. App. 565
    , 580-81 (2008). We based that conclusion on
    the Double Jeopardy Clause of the Fifth Amendment, which “protects against multiple
    punishments for the same offense.” Id. at 576 (quoting Brown v. Ohio, 
    432 U.S. 161
    , 165
    (1977)).
    - 14 -
    To date, however, neither our Supreme Court nor this Court has addressed in a published
    decision10 whether two violations of Code § 18.2-250 can be sustained when a defendant
    possesses two different controlled substances so mixed or fused together as to make them
    indivisible. Courts in other jurisdictions have divided on whether only a single prosecution is
    permitted in those circumstances.11 But Camann did not argue that he could be convicted of only
    a single felony for possessing the mixture of fentanyl and etizolam. He argues instead that the
    prosecution failed to prove that he had the mens rea to support the second conviction. We
    therefore assume without deciding that two prosecutions are permissible for possessing a single
    mixture, provided the mens rea requirement is satisfied.
    The inquiry then becomes whether the prosecution, to obtain two convictions under Code
    § 18.2-250, must prove that the defendant knew that a single mixture in his possession contained
    two controlled substances. We conclude that the statute indeed places that burden on the
    prosecution and that the prosecution failed to shoulder its burden here. Our conclusion is
    supported by the text of Code § 18.2-250, our Supreme Court’s rejection of a constructive
    knowledge requirement for possession, the history of this code section, and the general
    presumption that serious offenses require guilty knowledge.

    We address below our unpublished decision in Howard v. Commonwealth, No. 0780-
    17-1, 
    2018 WL 2604993
     (Va. Ct. App. June 5, 2018).

    Compare State v. Morgan, 
    140 N.E.3d 171
    , 178 (Ohio Ct. App. 2019) (“Clearly, if an
    individual has a baggie of, for example, heroin, in his left pocket and a baggie of fentanyl in his
    right pocket, he could be convicted and sentenced for each substance. We see no reason why an
    individual who chooses to engage in the sale or use of Schedule I controlled substances should
    escape responsibility for both Schedule I controlled substances simply by mixing one substance
    into the other.”), with State v. Owens, 
    579 A.2d 766
    , 768 (Md. 1990) (“Taking a common sense
    view of the matter, we are simply not persuaded that the legislature intended separate
    prosecutions and punishments for possession of PCP and possession of marihuana where the two
    substances have been, for all practical purposes, irrevocably joined as one.”).
    - 15 -
    a) The text of Code § 18.2-250
    We begin with the text of the statute. “Questions of statutory interpretation . . . are
    subject to de novo review on appeal, and we owe no deference to the circuit court’s interpretation
    of the statutory scheme.” Esposito v. Va. State Police, 
    74 Va. App. 130
    , 133 (2022). “When
    construing a statute, [the Court’s] primary objective ‘is to ascertain and give effect to legislative
    intent,’ as expressed by the language used in the statute.” Va. Elec. & Power Co. v. State Corp.
    Comm’n, 
    295 Va. 256
    , 262-63 (2018) (quoting Cuccinelli v. Rector & Visitors of the Univ. of
    Va., 
    283 Va. 420
    , 425 (2012)). “We must determine the legislative intent by what the statute
    says and not by what we think it should have said.” Miller & Rhoads Bldg., L.L.C. v. City of
    Richmond, 
    292 Va. 537
    , 541-42 (2016) (quoting Carter v. Nelms, 
    204 Va. 338
    , 346 (1963)).
    The statutory text here strongly suggests that proof of mens rea is required to convict a
    defendant under each indictment that alleges illegal possession of a Schedule I or II controlled
    substance:
    A. It is unlawful for any person knowingly or intentionally to
    possess a controlled substance unless the substance was obtained
    directly from, or pursuant to, a valid prescription . . . .
    ....
    (a) Any person who violates this section with respect to any
    controlled substance classified in Schedule I or II of the Drug
    Control Act shall be guilty of a Class 5 felony . . . .
    Code § 18.2-250 (emphases added). This language establishes a clear mens rea requirement, as
    it criminalizes only knowing or intentional possession. Nothing in the text supports the notion
    that as long as the defendant knows that he possesses one controlled substance, he can be
    convicted of as many felonies as the number of controlled substances found in the mixture.
    We disagree with the Commonwealth’s contrary view that if a defendant knowingly
    possesses “at least one controlled substance, . . . that knowledge is sufficient to convict him of
    possession of” every other controlled substance that may be identified through laboratory
    - 16 -
    analysis. The Commonwealth’s reading is not supported by the phrase “any controlled
    substance” in subpart (a), which provides that a “person who violates this section with respect to
    any controlled substance” is guilty of a Class 5 felony if the substance is listed on Schedule I or
    II. Code § 18.2-250(A)(a) (emphasis added). Quite simply, a defendant has not violated Code
    § 18.2-250 unless he does so “knowingly or intentionally.” Code § 18.2-250(A). Nothing in the
    word “any” justifies decoupling the mens rea from the actus reus required for each conviction for
    possessing a controlled substance.12
    b) The insufficiency of presumed knowledge
    The Commonwealth’s position would also revive a theory of constructive knowledge of
    drug possession that has been roundly rejected by the Supreme Court. More than 30 years ago,
    our Court held in Josephs v. Commonwealth, 
    10 Va. App. 87
     (1990) (en banc), that “[p]ossession
    of a controlled drug gives rise to an inference of the defendant’s knowledge of its character.” Id.
    at 101. But the Supreme Court overruled Josephs and rejected that presumption in Young v.
    Commonwealth, 
    275 Va. 587
     (2008). Young made clear that “[a]ctual or constructive possession
    alone is not sufficient. ‘The Commonwealth must also establish that the defendant intentionally
    and consciously possessed it with knowledge of its nature and character.’” 
    Id. at 591
     (citation
    omitted) (quoting Burton v. Commonwealth, 
    215 Va. 711
    , 713 (1975)). The Court called that
    knowledge “an essential element of the crime.” 
    Id.
     (emphasis added).
    12
    Even if the phrase “any controlled substance” supported the Attorney General’s strict-
    liability reading, it would at best render the statutory text ambiguous given the requirement in
    Code § 18.2-250(A) that a person “knowingly or intentionally” possess a controlled substance.
    Such ambiguity would call for applying the rule of lenity, thus construing the statute “strictly
    against the state and favorably to the liberty of the citizen.” Morgan v. Commonwealth, ___ Va.
    ___, ___ (Dec. 29, 2022) (quoting Sutherland v. Commonwealth, 
    109 Va. 834
    , 835 (1909)). As
    the discussion below confirms, applying the rule of lenity here would not “conflict with the
    implied or express intent” of the General Assembly and would not create “an overly ‘restrictive
    interpretation of the statute.’” 
    Id.
     (first quoting Kohl’s Dep’t Stores, Inc. v. Va. Dep’t of Tax’n,
    
    295 Va. 177
    , 188 n.8 (2018); and then quoting McGinnis v. Commonwealth, 
    296 Va. 489
    , 504
    (2018)).
    - 17 -
    By permitting multiple convictions for possession while treating as irrelevant whether the
    defendant knowingly possessed more than one controlled substance, the Attorney General would
    eliminate knowledge as an essential element of the additional counts charged. The
    Commonwealth conceded at oral argument that, under its reading of the statute, a defendant who
    thought he possessed just one controlled substance could be convicted of 15 felonies if chemical
    testing revealed the mixture contained 15 substances listed on Schedules I or II. Given that more
    than 400 controlled substances combined appear on those schedules, see Code §§ 54.1-3446,
    54.1-3448, it takes little imagination to envision double-digit felony indictments—each carrying
    a maximum punishment of ten years in prison, Code § 18.2-10(e)—against a defendant who
    thought he possessed just one illegal drug. The Commonwealth’s position creates a strict-
    liability regime for extra felony counts that cannot be reconciled with Young.
    c) The history of Virginia’s possession statute
    The history of Virginia’s possession statute further corroborates our conclusion that a
    conviction for possession under Code § 18.2-250 must be supported by proof of knowing
    possession.
    “[D]rug possession was never a common law crime,” State v. Sitton, No. 45088-7-II,
    
    2015 WL 161299
    , *4 (Wash. Ct. App. Jan. 13, 2015), and Virginia did not criminalize the
    possession of illicit drugs until the twentieth century. In 1908, Virginia criminalized the
    distribution of cocaine without a prescription, treating cocaine possession as “prima facie
    evidence of an intent to sell, give away or otherwise dispense the same.” 1908 Va. Acts ch. 255,
    §§ 1, 2 (codified at 1 Code of 1919, §§ 1696-97). The Supreme Court of Virginia interpreted
    that provision to require knowing possession, quoting a popular treatise for the proposition that a
    defendant “can only be required to account for the possession of things which he actually and
    - 18 -
    knowingly possessed.” Henderson v. Commonwealth, 
    130 Va. 761
    , 766-77 (1921) (quoting 3
    Simon Greenleaf, A Treatise on the Law of Evidence § 33 (16th ed. 1899)).
    In 1932, the National Conference of Commissioners on Uniform Laws (“National
    Conference”) proposed the Uniform Narcotic Drug Act, see Richard L. Braun, Uniform
    Controlled Substances Act of 1990, 
    13 Campbell L. Rev. 365
    , 365 (1991), which was
    “universally adopted by the states,” Ritter v. Commonwealth, 
    210 Va. 732
    , 742 (1970). Virginia
    adopted it in 1934. See 1934 Va. Acts ch. 86; Code of 1942, §§ 1654(1) to 1654(25); Code of
    1950, §§ 54-487 to 54-519.
    Section 2 of the Act made it “unlawful for any person to manufacture, possess, have
    under his control, sell, prescribe, administer, dispense, or compound any narcotic drug, except as
    authorized in this act.” 1934 Va. Acts ch. 86, § 2; Code of 1942, § 1654(2); Code of 1950,
    § 54-488.13 Noticeably absent from the text was any requirement that a person knowingly
    possess a narcotic drug.
    By 1963, however, most courts to consider the question had agreed that scienter was
    required, despite that “[k]nowledge of the alleged possessor, or his intention to possess, is not
    mentioned by the language of § 2.” B. Finberg, What constitutes “possession” of a narcotic
    drug proscribed by § 2 of the Uniform Narcotic Drug Act, 
    91 A.L.R.2d 810
    , 821 (1963). In
    1970, our Supreme Court joined that consensus, holding that scienter was needed to prove a
    violation:
    In order to convict a defendant of “possession” of a
    narcotic drug, within the meaning of Virginia’s Uniform Narcotic
    Drug Act, it generally is necessary to show that defendant was
    13
    The Act defined “narcotic drug” as “coca leaves and opium, and every substance not
    chemically distinguishable from them.” Code of 1942, § 1654(1), (13). The General Assembly
    later expanded the definition to include “cannabis.” 1952 Va. Acts ch. 451 (amending then-Code
    § 54-487); Johnson v. Commonwealth, 
    211 Va. 815
    , 819-20 (1971).
    - 19 -
    aware of the presence and character of the particular substance and
    was intentionally and consciously in possession of it.
    Ritter, 
    210 Va. at 741
    ; see Sierra, 59 Va. App. at 782 n.8 (tracing the scienter standard adopted
    in Ritter to the 1963 A.L.R. annotation).
    Also in 1970, the National Conference promulgated a new uniform law, the Uniform
    Controlled Substances Act, to replace the Uniform Narcotic Drug Act. See Braun, supra, at 365.
    The new uniform law was also quickly adopted by most States. Id. Virginia called its version of
    the law the “Drug Control Act.” See 1970 Va. Acts ch. 650. The Drug Control Act criminalized
    the possession of any “controlled drug,” id. (§ 54-524.101(c)), defined as “a drug or substance in
    Schedules I through V” of the act, id. (§ 54-524.2(b)(6)).
    The 1970 Act codified the scienter requirement that Ritter had found implicit under the
    1934 law: “It is unlawful for any person knowingly or intentionally to possess a controlled drug
    unless such substance was obtained directly or pursuant to a valid prescription or order from a
    practitioner . . . .” Code § 54-524.101(c) (emphasis added). Other than changing “controlled
    drug” to “controlled substance,” the text of the current statute—Code § 18.2-250—is virtually
    identical to the 1970 version. And despite many amendments over the years to the Drug Control
    Act, the General Assembly has never altered the knowing-possession requirement.
    In sum, the Supreme Court of Virginia required proof of scienter long before the
    predecessors to Code § 18.2-250 specified a mens rea requirement, and the General Assembly
    made clear that the Drug Control Act requires knowing possession. That legislative history
    undermines the Commonwealth’s suggestion that a defendant may be convicted of felony
    possession for every controlled substance that happens to be found in a mixture in his possession,
    without proof that the defendant was “intentionally and consciously in possession,” Ritter, 
    210 Va. at 741
    , of more than one controlled substance.
    - 20 -
    d) The presumption of mens rea for serious offenses
    The Commonwealth’s position also strays from what Justice Scalia and Professor Garner
    called the “Mens Rea Canon”:
    A statute creating a criminal offense whose elements are similar to
    those of a common-law crime will be presumed to require a
    culpable state of mind (mens rea) in its commission. All statutory
    offenses imposing substantial punishment will be presumed to
    require at least awareness of committing the act.
    Antonin Scalia & Bryan A. Garner, Reading Law: The Interpretation of Legal Texts 303 (2012).
    To be sure, the Supreme Court of Virginia has not yet explicitly adopted the mens rea
    presumption for serious statutory crimes. But Ritter implicitly did so. As noted above, the
    Uniform Narcotic Drug Act created a serious statutory offense, unknown at common law,
    without specifying any mens rea requirement. Still, Ritter concluded that the statute required
    proof of knowing possession. 
    210 Va. at 741
    . Likewise, in Maye, the Court inferred a scienter
    requirement in the larceny-after-bailment statute, finding that “the legislature implicitly intended
    that [scienter] must be proved.” 
    213 Va. at 49
    . In Esteban, by contrast, the Court held that
    felony possession of a firearm on school grounds was a “strict liability” offense when the statute
    contained no explicit knowledge requirement and the Court could discern no intent by the
    legislature to impose one. 
    266 Va. at 608-10
    . See generally Clayton v. Commonwealth, 
    75 Va. App. 416
    , 429-31 (2022) (Raphael, J., concurring) (describing the tension between Esteban
    and the mens rea presumption).
    For serious offenses that were not crimes at common law, courts in most American
    jurisdictions, including the Supreme Court of the United States, have recognized a mens rea
    presumption. 
    Id.
     at 425-30 & nn.5-6 (collecting authorities). As Justice Jackson put it in
    Morissette v. United States, 
    342 U.S. 246
     (1952), mens rea is not some “provincial or transient
    notion” but is “as universal and persistent in mature systems of law as belief in freedom of the
    - 21 -
    human will and a consequent ability and duty of the normal individual to choose between good
    and evil.” 
    Id. at 250
    . Applying a mens rea presumption for offenses imposing serious
    punishment reflects “the common-sense intuition that people should not be subject to lengthy
    prison terms for conduct that they did not know was wrongful.” Clayton, 75 Va. App. at 433
    (Raphael, J., concurring).
    We find the mens rea presumption appropriate here too. Given the legacy of Ritter and
    the General Assembly’s explicit inclusion of a knowledge requirement in Code § 18.2-250, this
    is an easy case for recognizing it.
    e) Howard
    Finally, we decline the Commonwealth’s invitation to resolve this case based on Howard
    v. Commonwealth, No. 0780-17-1, 
    2018 WL 2604993
     (Va. Ct. App. June 5, 2018).14 Howard
    upheld two convictions under Code § 18.2-250 for the defendant’s possession of a single
    powdery substance determined by chemical testing to contain two Schedule I or II substances,
    heroin and fentanyl. Slip op. at 2, 14, 
    2018 WL 2604993
    , at *1, *7. The defendant in Howard
    argued that if the Commonwealth could not prove that he intended to possess more than one
    controlled substance in the mixture, then “both of his convictions must be reversed.” Id. at 1,
    
    2018 WL 2604993
    , at *1. The Court rejected that claim, under which “the more drugs the
    capsule contained that appellant has in his possession, the more this Court is required to reverse
    each of appellant’s convictions.” Id. at 9, 
    2018 WL 2604993
    , at *4. We agree that the
    defendant’s theory in Howard was misguided.
    But “[r]equiring a mens rea showing for each count of possession does not make the first
    count of possession any harder to prove, only the subsequent counts.” Joshua P. Stock, A Tale of
    14
    Citation of an unpublished opinion is “permitted as informative, but will not be
    received as binding authority.” Rule 5A:1(f).

    Decision in Howard v. Commonwealth, 30 Geo. Mason U. Civ. Rts. L.J. 205, 229 (2020).15
    Howard failed to grapple with the problem that not requiring proof that the defendant knowingly
    possessed more than one controlled substance creates a strict-liability crime for every additional
    substance that may be found in the mixture.16
    We are not persuaded by Howard’s policy rationale that imposing criminal liability in
    this situation is justified by “the General Assembly’s considerable efforts to combat the problem
    of illegal drugs.” Slip op. at 5, 
    2018 WL 2604993
    , at *3. Combatting illegal drug possession is
    unquestionably important. But that is not the only value at stake. As shown above, the history
    of Code § 18.2-250 and its predecessors shows the critical importance of knowledge as “an
    essential element of the crime.” Young, 
    275 Va. at 591
    . We should not abrogate that protection
    unless the statute makes it unmistakably clear that the General Assembly intends to create a
    strict-liability offense.
    15
    Still, proving that a defendant knowingly possessed a mixture containing more than
    one controlled substance would not be the impossible burden suggested in Judge Athey’s dissent.
    For example, where a defendant knowingly possessed a drug by its street name, the prosecution
    might present testimony that the street name is commonly understood to refer to a combination
    of controlled substances, such as speedball, a “mixture of cocaine and heroin.” United States v.
    Paulino, 
    13 F.3d 20
    , 22 (1st Cir. 1994). See generally Drug Enforcement Agency, Slang Terms
    and Code Words: A Reference for Law Enforcement Personnel (July 2018),
    https://www.dea.gov/sites/default/files/2018-07/DIR-022-18.pdf.
    16
    The two out-of-state authorities on which Howard relied are also not persuasive. See
    Howard, slip op. at 11-12, 
    2018 WL 2604993
    , at *6-7 (discussing State v. Hall, 
    692 S.E.2d 446
    (N.C. Ct. App. 2010), and State v. Woodard, No. CA2016-09-084, 
    2017 WL 3128807
     (Ohio Ct.
    App. July 24, 2017)). Hall did not address the mens rea requirement for proving multiple counts
    arising from of possession of a single mixture. And the majority in Woodard appeared to assume
    the need to prove knowing possession of a mixture containing two controlled substances (heroin
    and fentanyl) but split with the dissent over whether the prosecution had successfully proven
    such knowledge. Compare Woodard, 
    2007 WL 3128807
    , at *6 n.2 (“Here, a jury found that
    appellant knowingly possessed two separate controlled substances . . . .”), with id., at *8
    (Ringland, J., dissenting) (“I have reservations about allowing two convictions under these
    circumstances where there is absolutely no evidence, either directly or circumstantially, that
    appellant knew the bag contained two separate opioid drugs.”).
    - 23 -
    2. The Commonwealth failed to prove scienter for the second controlled
    substance found in the mixture.
    The prosecution failed here to exclude the reasonable hypothesis of innocence that
    Camann knowingly possessed only one controlled substance—fentanyl—and did not know that
    the substance was a mixture that contained a second controlled substance. The prosecution had
    the burden to prove Camann’s knowing possession for each count charged. But the prosecution
    presented no evidence during its case-in-chief to show that Camann knew that there was more
    than one controlled substance in the white powder found in his wallet. The evidence did not get
    better for the Commonwealth on the etizolam charge after the defense’s case. While Camann
    admitted that the white powder was his and that he was a drug addict, he testified that he
    believed that the powder was fentanyl; he had “no idea” that it also contained etizolam, a
    substance he had “never heard of” before.17
    The failure of proof here is like that in Young. The defendant there was found with a
    prescription-pill bottle in her purse that contained a tablet that chemical testing revealed to be
    morphine. 
    275 Va. at 589
    . A witness testified that the pill bottle was hers, that she had
    inadvertently left it behind in the car driven by the defendant, and that the defendant had called
    to say that she had found the bottle. 
    Id. at 590
    . The Supreme Court held that the evidence could
    not exclude the reasonable hypothesis of innocence that the defendant did not know of the
    character of the contents of the pill bottle that turned out to be morphine. 
    Id. at 592
    . The Court
    observed that the officer “could not determine their nature without submitting them for
    laboratory analysis, and there is no reason to infer that the defendant was any better informed.”
    17
    Camann was not the only one unfamiliar with etizolam. The prosecutor, the sheriff’s
    deputy, the defense lawyer, and the trial judge all said at different points during the trial that they
    could not pronounce the name of the drug. The prosecutor called it “the E-drug” for short.
    - 24 -
    
    Id.
     “The ambiguous circumstantial evidence concerning the appearance of the bottle and its
    contents is as consistent with a hypothesis of innocence as it is with that of guilt.” 
    Id.
    The same is true here. The prosecution failed to exclude the reasonable hypothesis of
    innocence that Camann believed that the white powder contained only one controlled
    substance—fentanyl. The record lacks evidence to support a finding beyond a reasonable doubt
    that Camann knew that the white powder was a mixture that contained a second controlled
    substance as well.
    CONCLUSION
    We affirm the trial court’s decision denying Camann’s motion to suppress the evidence,
    but we reverse Camann’s conviction (CR21-215) for possession of a Schedule I or II controlled
    substance (etizolam).
    Affirmed in part, reversed and final judgment in part.
    - 25 -
    Athey, J., concurring in part and dissenting in part.
    I agree with the majority that the trial court correctly denied Camann’s suppression
    motion. I also concur with the majority in affirming his conviction for possessing fentanyl. But
    I disagree with the majority that, to satisfy the mens rea requirement for two separate convictions
    under Code § 18.2-250, the Commonwealth needed to prove Camann knew he possessed two
    separate controlled substances. I therefore respectfully dissent from the majority’s decision to
    reverse Camann’s conviction for possessing etizolam. Instead, I would have also affirmed
    Camann’s conviction for possession of etizolam under Code § 18.2-250 since the
    Commonwealth sufficiently established the requisite mens rea in support of both convictions by
    proving Camann knowingly possessed a controlled substance.
    “[T]he plain language of Code § 18.2-250 requires a defendant to know that the
    substance he possesses is in fact a controlled substance, but . . . it does not require him to know
    precisely what controlled substance it is.” Sierra v. Commonwealth, 
    59 Va. App. 770
    , 775
    (2012). As we have stated, the mens rea requirement in Code § 18.2-250 only applies to
    subsection (A). Id. at 778 (“[T]he General Assembly chose to specify a requisite degree of mens
    rea only in the general proscription against possessing controlled substances in the first
    paragraph of subsection (A).”). “Nowhere, however, in subparts (a)-(c) did the General
    Assembly insert a mens rea requirement.” Id. at 777-78. Instead, subparts (a)-(c) focus on the
    defendant’s actus reus and the specific type (or in this case, types) of substance(s) found in the
    defendant’s possession. Id. at 778 (“The specific type of substance found in a defendant’s
    possession is an actus reus element the Commonwealth must prove pursuant to subparts (a)-(c)
    of Code § 18.2-250(A), but it is not an element to which the mens rea requirement found earlier
    in Code § 18.2-250(A) applies.”).
    - 26 -
    “[T]he General Assembly has chosen not to excuse a defendant who knows he is
    possessing a controlled substance, but is unaware or perhaps mistaken as to the precise identity
    of the specific substance he is possessing . . . .” Id. at 779. The legislature has decided that if a
    defendant knows that the substance he possesses is controlled, he bears the risk of incurring
    whatever punishment is prescribed for possessing everything in that specific substance. Id. (“A
    defendant who intentionally possesses a controlled substance, aware of its nature and character
    as such, bears the risk of incurring whatever punishment the General Assembly has prescribed
    for the possession of the specific substance he has. This is the policy the legislature has
    embraced, and we will not substitute our own policy for that of the legislature.”).
    Accordingly, I take issue with the majority requiring the Commonwealth to prove
    Camann knew the precise number of controlled substances in the mixture he possessed in order
    to be convicted of a corresponding number of counts under Code § 18.2-250.18 “[T]he plain
    language of Code § 18.2-250 indicates the legislature’s intent to criminalize the knowing and
    intentional possession of ‘a controlled substance,’ whatever that controlled substance may turn
    out to be.” Id. at 778. Here, what Camann possessed turned out to contain two separate
    controlled drugs: fentanyl and etizolam. While Camann did need to know that he possessed a
    controlled substance to be convicted, he “[did] not need to know the exact nature of the
    substance in his possession, only that it was a controlled substance of some kind.” Id. at 781
    (emphasis added) (quoting United States v. Martin, 
    274 F.3d 1208
    , 1210 (8th Cir. 2001)).
    18
    Although the majority argues it is only requiring Camann to know how many
    controlled substances he possessed, not which controlled substances he possessed, based on the
    majority’s interpretation of Code § 18.2-250, this seems a distinction without a difference. From
    a practical standpoint, I doubt whether the Commonwealth could prove a defendant knew how
    many controlled substances he possessed without also proving the defendant knew which
    controlled substances he possessed.
    - 27 -
    Additionally, as the majority aptly states, under Sierra, “if a person thinks he has heroin,
    but it turns out to be fentanyl, that person has still ‘knowingly or intentionally . . . possess[ed] a
    controlled substance.’” Code § 18.2-250; Sierra, 59 Va. App. at 783-84. But the majority
    seemingly argues that Sierra should apply with less force when a defendant thinks he possesses
    heroin, but actually possesses a mixture containing heroin and fentanyl. In that case, the
    defendant, like Sierra, would still know he possessed a controlled substance and would still be
    mistaken as to the precise controlled drug or drugs making up the controlled substance. Thus,
    consistent with Sierra, the defendant’s mistake as to the specific controlled substances in the
    mixture cannot be a defense under the plain meaning of Code § 18.2-250. Sierra, 59 Va. App. at
    783-84 (“A claim by a defendant that he knew he was possessing a controlled substance, but was
    unaware or mistaken as to the precise identity of that substance, is not a defense under Code
    § 18.2-250.”).
    While I appreciate the majority’s concern regarding some of the potentially harsh
    outcomes that could result from interpreting the statute based on its plain meaning as supported
    by Sierra, such fears seem to arise from the potential policy implications, not legal interpretation.
    See Daily Press, LLC v. Off. of Exec. Sec’y of Sup. Ct., 
    293 Va. 551
    , 557 (2017) (“Public policy
    questions concerning where to draw the line . . . fall within the purview of the General
    Assembly. In a regime of separated powers that assigns to the legislature the responsibility for
    charting public policy, our function is limited to adjudicating . . . question[s] of law . . . .”). Our
    “drug statutes require specific knowledge or intent as to a general category of unlawful items.
    The specific unlawful items, however, are found in the penalty section of the scheme.” Sierra,
    59 Va. App. at 781 (emphasis added) (quoting United States v. Barbosa, 
    271 F.3d 438
    , 458 (3d
    Cir. 2001)) (explaining how the reasoning behind 
    21 U.S.C. § 841
     “applies with equal force to
    Code § 18.2-250”). Thus, we cannot “arbitrarily add specific mens rea requirements to elements
    - 28 -
    of an offense where the General Assembly has expressly prescribed what mens rea requirements
    it wishes to impose.” Id. at 778. “Such public policy arguments cannot contravene clear
    statutory language and should be addressed to the legislature, not the courts.” Hartford
    Underwriters Ins. Co. v. Allstate Ins. Co., ___ Va. ___, ___ (Dec. 8, 2022).
    Since I would have affirmed Camann’s convictions for possession of both fentanyl and
    etizolam pursuant to Code § 18.2-250, I respectfully dissent.
    - 29 -
    Chaney, J., concurring in part and dissenting part.
    I concur with the majority’s holding that the evidence is insufficient to prove that Camann
    knowingly or intentionally possessed both fentanyl and etizolam in violation of Code § 18.2-250
    because the evidence fails to prove that Camann knew that the white powder in his possession
    contained more than a single controlled substance. I dissent, however, from the majority’s opinion
    affirming the trial court’s denial of Camann’s suppression motion because I conclude that the
    deputies obtained the drugs in violation of Camann’s constitutional rights against unreasonable
    searches and seizures. See U.S. Const. amend. IV.
    I. NO REASONABLE SUSPICION FOR THE INVESTIGATIVE SEIZURE
    Deputy Spears and Deputy Russell observed Camann outside the 7-Eleven convenience
    store when they arrived to investigate a public-indecency complaint. Deputy Spears initially
    conversed with Camann during a consensual encounter while Deputy Russell investigated inside the
    store. Camann’s police encounter was no longer consensual when Deputy Spears directed him to
    move his left foot so the deputy could inspect a piece of foil next to and partially under Camann’s
    shoe. As the majority recognizes, Camann was seized when he submitted to the deputy’s authority
    and lifted his foot. See Terry v. Ohio, 
    392 U.S. 1
    , 19 n.16 (1968) (recognizing that a seizure has
    occurred “when the officer, by means of physical force or show of authority, has in some way
    restrained the liberty of a citizen”); Cochran v. Commonwealth, 
    258 Va. 604
    , 608 (1999)
    (recognizing that a seizure occurs when a person submits to an officer’s show of authority).
    Contrary to the majority’s opinion, Deputy Spears’s seizure of Camann was not a lawful
    investigative detention. Under Terry and its progeny, a police officer may lawfully detain a person
    to make reasonable inquiries when the officer has reasonable, articulable suspicion to believe that
    the person is engaged in criminal activity. See Terry, 
    392 U.S. at 21-22
    . “Whether an officer has a
    reasonable suspicion to justify . . . a detention is ‘based on an assessment of the totality of the
    - 30 -
    circumstances.’” Hill v. Commonwealth, 
    68 Va. App. 610
    , 619 (2018) (alteration in original)
    (quoting Branham v. Commonwealth, 
    283 Va. 273
    , 280 (2012)). “When examining the officer’s
    articulable reasons for stopping a person, we examine the objective reasonableness of the officer’s
    behavior rather [than] the officer’s subjective belief that the conduct indicates criminal activity.”
    Riley v. Commonwealth, 
    13 Va. App. 494
    , 496-97 (1992) (citing Terry, 
    392 U.S. at 21-22
    ).
    The totality of the circumstances at the time of the seizure did not give rise to reasonable,
    articulable suspicion that Camann was engaged in criminal drug activity. Although the police were
    called to investigate a complaint about alleged indecent conduct outside the store, there was no
    complaint of criminal drug activity. There is no evidence that the store was in an area known for
    drug activity. Neither deputy saw Camann engaged in any drug activity when they observed him
    standing by the store. Neither deputy saw Camann with any drugs or drug paraphernalia. Neither
    deputy observed any indicia that Camann was under the influence of drugs when they conversed
    with him. After noticing a piece of foil next to and partially under Camann’s left foot, Deputy
    Spears seized Camann based on (1) the deputy’s training and experience that aluminum foil is
    commonly used to smoke narcotics and (2) the deputy’s hunch that Camann was concealing drug
    evidence under his foot. But such an unparticularized suspicion and hunch are insufficient to justify
    the investigative seizure of Camann. See Terry, 
    392 U.S. at 27
     (holding that police must have more
    than an unparticularized suspicion or hunch to justify an investigatory stop). Neither deputy saw
    Camann hold, use, or discard the foil before they noticed it under Camann’s shoe. Before Deputy
    Spears seized Camann, neither deputy saw anything on or near the foil to indicate that the foil was
    drug-related.19 Considered objectively, the totality of the circumstances at the time Camann was
    seized was insufficient to give rise to reasonable, articulable suspicion that criminal drug activity
    19
    The burnt residue on the foil was never identified, and none of Camann’s convictions
    are based on the foil or its contents.
    - 31 -
    was afoot. Under these circumstances, the deputy’s observation of a suspected act of concealment
    by Camann did not legally justify the seizure. See Smith v. Commonwealth, 
    12 Va. App. 1100
    ,
    1104 (1991) (holding that police unlawfully seized the defendant based on suspected concealment
    of drugs when the defendant “quickly move[d] to put his hand into his pants when the officer’s
    marked car came into view” in an area known for significant drug activity); Riley, 
    13 Va. App. 494
    (holding that police unlawfully seized the defendant based on suspected concealment of drugs when
    the defendant, in a high crime area, turned and reached toward his waistband upon seeing the
    officer); Goodwin v. Commonwealth, 
    11 Va. App. 363
    , 367 (1990) (holding that police unlawfully
    seized the defendant based on suspected concealment of a weapon when the defendant “shoved his
    hand in his coat pocket, apparently upon seeing the approaching patrol car”). Camann’s subsequent
    admission that he was concealing the foil underfoot does not add to the objective facts available to
    the deputy at the time of the seizure and does not convert the deputy’s hunch into reasonable
    suspicion.
    Even if, based on reliable witness reports, the deputies had reasonable suspicion to detain
    Camann to investigate alleged public indecency, Deputy Spears’s directive that Camann move his
    left foot was unlawful because the directive exceeded the scope of a lawful investigative detention
    related to the witnesses’ complaints. See Terry, 
    392 U.S. at 29
     (holding that an investigative
    detention must be “reasonably related in scope to the justification for [its] initiation”). Since the
    deputy’s inspection of the foil was not reasonably related to the investigation of alleged public
    indecency, the seizure of Camann to investigate the foil violated Camann’s constitutional right
    against unreasonable seizures.
    Since Deputy Spears seized Camann in violation of his Fourth Amendment rights, the
    evidence obtained pursuant to the unlawful seizure and subsequent arrest should have been
    suppressed and the convictions based on such evidence should be reversed. See Davis v.
    - 32 -
    Commonwealth, 
    37 Va. App. 421
    , 435 (2002) (reversing drug conviction where police unlawfully
    detained defendant without reasonable, articulable suspicion that defendant was involved in
    criminal activity and drugs were found as a result of the unlawful seizure). Because the evidence
    seized from Camann should have been suppressed, there would be insufficient evidence to sustain
    any drug convictions on retrial. Accordingly, I would reverse the trial court’s judgment denying
    Camann’s suppression motion, vacate Camann’s convictions, and dismiss the drug charges.20 See
    Whitehead v. Commonwealth, 
    278 Va. 300
    , 315-16 (2009) (citing Jackson v. Commonwealth, 
    267 Va. 666
    , 681 (2004)).
    II. NO PROBABLE CAUSE TO ARREST FOR POSSESSION OF A CONTROLLED SUBSTANCE
    Assuming arguendo that the pre-arrest seizure of Camann was constitutional, I disagree
    with the majority’s conclusion that the discovery of the full-size straw and burnt residue on the
    foil gave the deputies probable cause to arrest Camann for possession of a controlled substance.
    “‘[P]robable cause’ to justify an arrest means facts and circumstances within the officer’s
    knowledge that are sufficient to warrant a prudent person, or one of reasonable caution, in
    believing . . . that the suspect has committed, is committing, or is about to commit” the crime for
    20
    Camann’s motion to suppress clearly moved the trial court to suppress all evidence
    obtained from the warrantless seizure and search of his person. Camann did not separately move
    to suppress the evidence found in his wallet and the rest of the evidence also found on his person.
    Camann’s first assignment of error on appeal to this Court states:
    The trial court erred in denying the Appellant’s motion to suppress
    the narcotics seized from his wallet, because the police officer’s
    search of the Defendant’s person and wallet violated his rights
    under the Fourth and Fourteenth Amendments of the United States
    Constitution and Article I, Sections 8 and 10 of the Virginia
    Constitution in that the Defendant’s seizure and search of his
    person and wallet were not supported by probable cause.
    Amended Op. Br. 1-2. Although this assignment of error was inartfully drafted, it sufficed to
    inform the Commonwealth and this Court that Camann’s appeal challenged the trial court’s
    ruling denying his motion to suppress. Thus, this assignment of error is not reasonably read as
    being limited to the suppression of the evidence found in Camann’s wallet.
    - 33 -
    which he is arrested. Dodd v. Commonwealth, 
    50 Va. App. 301
    , 307 (2007) (second alteration in
    original) (quoting Thomas v. Commonwealth, 
    38 Va. App. 49
    , 53 (2002)). Deputy Spears
    immediately arrested and handcuffed Camann when the foil under Camann’s foot was fully
    exposed, revealing a burn mark on the foil and a full-size straw. But neither Deputy Spears nor
    Deputy Russell testified to observing any substance on or inside the straw and neither deputy’s
    testimony indicated the identity of the burnt residue on the foil. Under the totality of these
    circumstances, a reasonably cautious officer would have examined or tested the foil and straw
    for the presence of a controlled substance before arresting Camann. However, although Deputy
    Spears subsequently tested the powder found in Camann’s wallet to determine whether there was
    probable cause to believe that the powder was a controlled substance, the deputies did not test
    the residue on the foil for the presence of a controlled substance.21
    To lawfully arrest someone for the offense of possession of a controlled substance, “an
    officer must have probable cause to believe ‘the defendant was aware of the presence and
    character of the drugs and that he intentionally and consciously possessed them.’” Dodd, 50
    Va. App. at 307 (quoting Castaneda v. Commonwealth, 
    7 Va. App. 574
    , 583 (1989) (en banc)).
    Here, the deputies did not have probable cause to believe that a controlled substance was present
    on the foil or the straw, let alone probable cause to believe that Camann was aware of the
    presence and character of such substance. Thus, even if Deputy Spears’s pre-arrest seizure of
    Camann was lawful, the warrantless arrest of Camann without probable cause was unlawful.
    Because the drugs were found on Camann when the deputies searched him incident to the
    unlawful arrest—in violation of his Fourth Amendment rights—the drugs found on Camann
    should have been suppressed. See, e.g., Jefferson v. Commonwealth, 
    27 Va. App. 1
    , 19-20
    21
    The Virginia Department of Forensic Science has approved field tests for
    law-enforcement officers to use to determine whether there is probable cause to believe that a
    substance is a controlled substance. See Code § 19.2-188.1(A).
    - 34 -
    (1998) (holding that the trial court should have suppressed evidence found in a warrantless
    search of the defendant incident to the unlawful arrest of the defendant).
    Contrary to the majority’s opinion, the cases cited by the majority do not support the
    conclusion that the deputy’s discovery of burnt residue on the foil gave the deputy probable
    cause to arrest Camann for possession of a controlled substance. In Carson v. Commonwealth,
    
    12 Va. App. 497
     (1991), an officer seized as contraband a one-and-a-half to two-inch straw that
    was in plain view on the driver’s seat of a car, between the driver’s legs. Id. at 499. The officer
    testified in Carson that from his experience in drug enforcement work, he “recognized the straw
    as the type ‘that people use to ingest cocaine through their nose.’” Id. This Court found that
    “[t]he uniqueness of the straw’s size distinguishes it from straws one would usually encounter for
    legitimate purposes.” Id. at 502. Therefore, the straw in Carson is distinguishable from the
    full-size straw at issue here. This Court held in Carson that “[t]he distinctive character of the
    straw coupled with the officer’s experience ‘would warrant a man of reasonable caution’ to
    believe that the straw might be useful as evidence of a crime.” Id. (emphasis added). Thus, we
    held that the officer’s seizure of the straw was lawful. This Court further held in Carson that the
    officer’s discovery of white powder residue on the straw gave the officer probable cause to
    search the car from which the straw was lawfully seized—not probable cause to arrest the driver
    for possession of a controlled substance.
    Here, in contrast with Carson, the evidence does not show that the foil and full-size straw
    found outside the 7-Eleven store have characteristics that distinguish them from foil and straws
    used for legitimate purposes. Foil can be used to cook or wrap food or to extinguish a cigarette,
    among myriad other legitimate purposes. Neither Deputy Spears nor Deputy Russell identified
    the burnt residue on the foil as a controlled substance. Despite Deputy Spears’s knowledge that
    - 35 -
    foil and straws are commonly used to smoke narcotics, the totality of the circumstances here did
    not give the deputies probable cause to believe that Camann possessed a controlled substance.
    In Commonwealth v. Ramey, 
    19 Va. App. 300
     (1994), this Court held that an officer had
    probable cause to seize “a homemade ‘bong’ used for smoking illegal drugs” that was seen in
    plain view protruding from a pack worn by the defendant. Id. at 301. This holding is based on
    “the distinctive character of the plastic bottle with foil on top and the highly unlikely event that it
    would have a legitimate use.” Id. at 304. Ramey did not address whether the officer had
    probable cause to arrest the defendant for possession of a controlled substance.
    The majority cites three cases from our sister states in purported support of the majority’s
    conclusion that the discovery of burnt residue on the foil gave the deputies probable cause to
    arrest Camann for possession of a controlled substance. But the cited authorities do not support
    the majority’s opinion. In State v. Rose, 
    282 P.3d 1087
    , 1093 (Wash. 2012) (en banc), the court
    held that the officer had probable cause to arrest the defendant for possession of a controlled
    substance where the officer saw chalky white residue in a glass tube protruding from the
    defendant’s bag. Id. at 1088, 1092-93. The officer in Rose testified that based on his training,
    the residue was consistent with smoking of some substance. Id. at 1093. The officer also
    testified that in his training and experience, he suspected the glass pipe with white residue inside
    “were consistent with drug possession” and he suspected the residue was either
    methamphetamines or cocaine. Id. In contrast with the officer’s testimony in Rose, the deputies
    who testified here did not identify the observed residue as a controlled substance. But in Rose,
    the officer’s identification of the residue as a controlled substance was essential to the court’s
    holding that the officer had probable cause to arrest the defendant for possession of a controlled
    substance. See id. at 1092-93. Therefore, Rose does not support the majority’s opinion.

    In People v. Edwards, 
    925 N.E.2d 576
    , 577 (N.Y. 2010), the court held that the police
    had probable cause to arrest the defendant based on the officer’s observation of cocaine residue
    on the defendant’s hand. As in Rose, the arresting officer in Edwards identified the observed
    residue as a controlled substance, distinguishing Edwards from Camann’s case. Therefore,
    Edwards does not support the majority’s opinion.
    In Bright v. State, 
    455 S.E.2d 37
    , 52 (Ga. 1995), the defendant was arrested for
    possession of a controlled substance after the police stopped his car pursuant to a lookout and
    “discovered on the window ledge outside the door of the car an object which the officer
    recognized to be a crack pipe containing residue of crack cocaine.” In addition to identifying the
    pipe as a distinctive crack pipe, the officer testified to his familiarity with crack cocaine residue.
    See 
    id.
     As in Rose and Edwards, the court’s holding that the police had probable cause to arrest
    the defendant for possession of a controlled substance was based on the officer’s identification of
    the observed residue as a controlled substance. Therefore, like Rose and Edwards, Bright does
    not support the majority’s opinion.
    It appears that there is no authoritative caselaw supporting the majority’s opinion that the
    discovery of unidentified burnt residue on a piece of foil is sufficient to provide probable cause
    to arrest a possessor of the foil with possession of a controlled substance. As explained above,
    the totality of the circumstances here—including the discovery of burnt residue on the foil under
    Camann’s foot—did not provide probable cause to arrest Camann for possession of a controlled
    substance. Absent probable cause to arrest Camann, the deputies searched Camann and found
    the drugs pursuant to an unlawful arrest, in violation of Camann’s Fourth Amendment rights.
    Therefore, the drugs should have been suppressed and Camann’s drug convictions should be
    reversed. See Jefferson, 27 Va. App. at 19-20.
