OPINION OF THE COURT
Richard “Bird” Hodge and Akil Greig appeal their convictions on drug and fire *431 аrm charges. Greig also appeals his conviction for assault on a federal officer. The primary issue in this appeal is whether the appellants possessed and distributed a “controlled substance analogue” within the meaning of 21 U.S.C. § 802(32)(A) when they sold a mixture of candle wax and flour to undercover agents under the pretense that it was crack cocaine. We hold that the wax and flour mixture is not a controlled substance analogue.
I. Background
On April 12, 1999, Special Agent Michael Patrick of the Bureau of Alcohol, Tobacco, and Firearms, posing as a Jamaican drug dealer and accompanied by a confidential informant (“Cl”), entered the Paul M. Pearson Housing Community in St. Thomas, United States Virgin Islands. Another officer videotaped the operation from a distance and the Cl wore a “wire” recording device. Patrick and the Cl approached a group of individuals that included Hodge and inquired about purchasing crack cocaine. Hodge informed them that he had nothing with him, but that they should return in approximately one hour.
After Patrick and the Cl left, Yambo Williams, an acquaintance of Hodge and Greig, retrieved a mixture of candle wax and flour which “looked like crack.” Hodge divided the mixture into two packages. He gave one package to Greig to sell to the “Yardies” 1 — by which he meant Patrick and the Cl — under the pretense that it was crack cocaine. Hodge, Greig, Williams, and Williams’s father intended to defraud Patrick and the Cl of $800, the price of an ounce of crack cocaine, and share the proceeds. In addition, Greig had a gun with him and announced that he planned to rob the Yardies when they returned, but Hodge told him that a gun would not be necessary.
When Patrick and the Cl returned to the Pearson Housing Community at around 11 a.m., Hodge was not present, but Williams and Greig were. Greig informed them that Hodge had sent him to complete the transaction. In an alley, Patrick paid $800 for the wax/flour mixture, which he described as a “rock crystalline substance.” Patrick and the Cl turned to leave, but Greig called them back and asked if they would like another ounce for $600. Patrick stated that he was not interested in additional purсhases. At the same time, Williams tugged on Patrick’s shirt, exposing his firearm. Patrick attempted to exit the alley, but Greig then grabbed Patrick by his shirt and tried to pull him back. After a momentary scuffle, Patrick shoved free from Greig. As Patrick was walking away he heard a gun shot fired behind him. He turned around to see Williams, Greig, and the Cl, but he could not tell who fired the gun. Williams then fled into apartment 81 of the housing community. Greig followed him into the apartment and gave him his gun. Williams escaped from the back door to the apartment and tossed the firearm onto the balcony of apartment 95. It was later recovered with five rounds of ammunition remaining in the cylinder chamber; one round had been fired.
Greig, Hodge, and Williams subsequently were arrested and indicted.

pleаded guilty and testified for the prosecution; Hodge and Greig were tried together. A jury in the United States District Court for the Virgin Islands convicted Greig on Counts I (assault on a federal officer), II (using a firearm during a drug trafficking crime and a crime of violence), IV (conspiracy to possess with intent to distribute a controlled substance analogue), and V (possession with intent to distribute a controlled substance analogue). The jury convicted Hodge on Counts III (using a firearm during a drug trafficking crime); IV (conspiracy to possess with intent to distribute a controlled substance analogue), and V (possession with intent to distribute a controlled substance analogue). Greig was sentenced to twenty-four months imprisonment for his convictions on Counts I, IV, and V, to be sеrved concurrently, and to ten years imprisonment for his conviction on Count II, to be served consecutively to his sentences on Counts I, IV, and V. Hodge was sentenced to twenty-one months imprisonment for his convictions on Counts IV and V, to be served concurrently, and to ten years imprisonment for his conviction on Count III, to be served consecutively to his sentences on Count IV and V. Both defendants filed motions for a judgment of acquittal pursuant to Fed.R.Crim.P. 29 and for a new trial pursuant to Fed. R.Crim.P. 33. The District Court denied both motions,

II. Discussion
A Controlled Substance Analogue
1. Background
A “controlled substance analogue,” which is defined more precisely below, is “substantially similar” to a controlled substance but not specifically prohibited under the federal drug laws. 21 U.S.C. § 802(32)(A). The Controlled Substance Analоgue Enforcement Act of 1986 (the “Analogue Act”) provides that “[a] controlled substance analogue shall, to the extent intended for human consumption, be treated, for the purposes of any Federal law as a controlled substance in schedule I.” 21 U.S.C. § 813. The object of the Analogue Act is to prevent underground chemists from producing slightly modified drugs that are legal but have the same effects and dangers as scheduled controlled substances. Examples of controlled substance analogues include gamma-butyrolaetone, an analogue of GHB (more commonly called the “date-rape drug”), and l-(3-oxy-3 phenyl-propyl)-4 phenyl-4-propionoxypiperidine, which is a synthetic form of heroin.
See United States v. Fisher, 289
F.3d 1329 (11th Cir. 2002);
United States v. Ono,
The statutory definition of the term “controlled substance analogue” states:
*433 [With certain exceptions not relevant here,] the term “controlled substance analogue” means a substance -
(i) the chemical structure of which is substantially similar to the chemical structure of a controlled substance in schedule I or II;
(ii) which has a stimulant, depressant, or hallucinogenic effect on the central nervous system that is substantially similar to or greater than the stimulant, depressant, or hallucinogenic effect on the central nervous system of a controlled substance in schedule I or II; or
(iii) with respect to a particular person, which such person represents or intends to have a stimulant, depressant, or hallucinogenic effect on the central nervous system that is substantially similar to or greater than the stimulant, depressant, or hallucinogenic effect on the central nervous system of a controlled substance in schedule I or II.
21 U.S.C. § 802(32)(A).
The Government, focusing on the word “or” between subparts (ii) and (iii), proposes a disjunctive interpretation for § 802(32)(A), namely that a substance is a controlled substance analogue if it satisfies any one of clauses (i), (ii), or (iii). If so, the mixture of candle wax and flour that Hodge and Greig sold appears to be a controlled substance analogue under sub-part (iii). Hodge and Greig “repre-sentad]” their product to be crack cocaine and, therefore, to have a “stimulant ... effect on the central nervous system” “substantially similar” to a “controlled substance in schedule I or II.” Appellants, on the other hand, read § 802(32)(A) conjunc-tively. They argue that a controlled substance analogue must satisfy both clause (i) and either clause (ii) or (iii). A candle wax and flour mixture is not “substantially similar” in chemical structure to crack cocaine as required under clause (i). Accordingly, under appellants’ reading, it cannot be a controlled substance analogue regardless whether they represented it to be crack cocaine.
The District Court in this case rеad the definition disjunctively, but every other federal court to consider the issue has read it conjunctively. We exercise plenary review over the District Court’s interpretation of a statute and, more generally, its legal conclusions.
See In re CM Holdings, Inc.,
In
United States v. Forbes,
The District Court for the Southern District of New York reached a similar conclusion in
United States v. Roberts,
In
United States v. Clifford,
Next, the District Court for the Northern District of Georgia in
United States v. Vickery,
Finally,
United States v. Klecker,
Parting company with the above decisions, the District Court in this case determined that § 802(32)(A) must be read dis-junctively.
Greig,
[t]he structure of section 802(32)(A) and the plain meaning of its language compel the conclusion that this is an ordinary disjunctive series. In all three clauses, a dependent relative clause modifying a precedent noun is signaled by the relative pronoun “which.” In each case, the precedent noun is “a substance,” which is found in the main clause.
Id.
Turning to the legislative history, the District Court found that neither the House nor the Senate intended to require proof by the Government of both a chemical structure substantially similar to that of a controlled substance
and
a substantially similar effect. The House version of the bill initially included the word “and” after clause (i) and its three prongs were structured differently so that what is now clause (i) was more obviously a requirement in every case; however, these indications of a conjunctive meaning were deleted from the final version without explanation.
4
Likewise, the Senate’s version of the bill required the Government to prove either that the alleged controlled substance analogue possessed a chemical structure “substantially similar to the chemical structure of a controlled substance” or was “specifically designed to produce an effect substantially similar to, or greater than, the effect of a controlled substance,” but not both.
Id.
at 393 (quoting 132 Cong. Rec. 30322, 30329 (1986)) (emphasis added by the District Court). “Since there is no ‘clearly expressed legislative intention to the contrary,’” the Distriсt Court noted that it “must follow the Supreme Court’s directive and regard the plain language of section 802(32)(A) as conclusive.”
Id.
at 393-94 (quoting
American Tobacco Co. v. Patterson,
We reject the District Court’s disjunctive reading and adopt instead the conjunctive reading endorsed in Forbes, Roberts, Clifford, Yickery, and Klecker. Our reasoning is similar to that of these district courts. In short, we conclude that the plain meaning of § 802(32)(A) is ambiguous and that the legislative history indisputably favors the conjunctive reading.
2. Plain Meaning
We begin, of course, with the plain meaning of a statute.
See Smith v. Fid. Consumer Disc. Co.,
This proposition •— that “or” between two words indicates that each can stand alone — decides the ordinary case. But is this the “ordinary” case,
i.e.,
does “the context dictate otherwise”? Here, even within § 802, Congress did not always consider a single “or” between the final terms of a series sufficient evidence of disjunctive intent. As noted in
Clifford,
the definition of “depressant or stimulant substance” in § 802(9) contains an “or” after each clause.
Indeed, in the context of the Analogue Act, we think that the definition of a controlled substance analogue reads more naturally in the conjunctive. First, clause (i) seems to state an independent requirement; even the dictionary defines chemical analogues in terms of their similar chemical structures.
5
See
American Heritage Dictionary 65-66 (3d ed.1992) (defining “analogue” in chemistry as “[a] structural derivative of a parent compound that often differs from it by a single element”). At the same time, clauses (ii) and (iii) read in parallel and appear subordinate to clаuse (i) because the functional language in each begins with the relative pronoun “which.” The doctrine of the last antecedent teaches that “qualifying words, phrases, and clauses are to be applied to the words or phrase immediately preceding” and not to “others more remote.”
See Resolution Trust Corp. v. Nernberg,
Notwithstanding this analysis, we readily concede that the disjunctive reading is plausible. The word “or” between clauses (ii) and (iii) does not prove that all three *437 clauses of § 802(32)(A) are disjunctive, only that many people would read it that way. With two possible readings, we conclude that § 802(32)(A) is ambiguous as to whether it should be read conjunctively or disjunctively.
3. Legislative History
When the language of a statute is ambiguous, we look to its legislative history to deduce its purpose.
See Gerbier v. Holmes,
The Analogue Act’s purpose is to make illegal the production of designer drugs and other chemical variants of listed controlled substances that otherwise would escape the reach of the drug laws. This was the goal — the only goal — announced by legislators during debate on the House and Senate versions of the bill that became the Analogue Act. See, e.g., 131 Cong. Rec. 19114 (1985) (statement of Sen. Thurmond) (“This proposal will prevent underground chemists from producing dangerous designer drugs by slightly changing the chemical composition of existing illegal drugs.”); 131 Cong. Rec. 27311 (1985) (statement of Sen. D’Amato) (stating that the Analogue Act “closes the loophole in present law that allows the creаtion and distribution of deadly new drugs without violating Federal law”); 131 Cong. Rec. 32950 (1985) (statement of Rep. Lungren) (“The focus of this proposal is clearly to impact on the designer drug phenomena by making it illegal for the clandestine chemists to manufacture and distribute these substances.”). Congress was concerned about chemicals that have been altered by “adding a fluoride or an extra carbon molecule” from their scheduled counterparts, 131 Cong. Rec. 27311 (1985) (statement of Sen. D’Amato), not about mundane compounds such as candle wax and flour. See 131 Cong. Rec. 32950 (1985) (statement of Rep. Lungren) (explaining that “this proposal is not intended to cover alcoholic beverages, tobacco products, aspirin, or оther legitimate consumer products”).
The District Court emphasized that while the House’s original version of § 802(32)(A) unambiguously was phrased conjunctively and the Senate’s version was phrased disjunctively, the final version was “an amalgam of the House and Senate versions” that “effectively transformed the House’s original two prongs into three prongs, deleted the House’s conjunctive ‘and,’ included the Senate’s ‘substantially similar’ language in subpart (ii), and retained the disjunctive ‘or’ between sub-parts (ii) and (in).”
Greig,
We disagree. What the District Court overlooks is that neither the original House nor Senate version evidenced any *438 intent to extend the drug laws to substances, like wax and flour, that bear no similarity to scheduled controlled substances. The House version, as already described, required both a similar chemical structure to a controlled substance and a similar effect. Id. at 390. The Senate version required either a similar chemical structure or that the substance was “specifically designed” to produce the effect of a controlled substance. Id. at 393. Thus, while the Senate version was disjunctive in one sense, both prongs of its test plainly referred to attempts to create actual chemical substitutes for scheduled controlled substances. Neither the Senate version nor the House version had anything to do with criminalizing the sale of non-drugs labeled as scheduled сontrolled substances. Accordingly, whether the final draft of § 802(32)(A) was an “amalgam” of the House and Senate version does not affect our conclusion. Two competing versions of the same law, neither of which would impose liability separately, do not result in liability when put together. 6
Further, we fundamentally disagree with the District Court’s implicit presumption that § 802(32)(A) criminalizes the appellants’ conduct absent a clear legislative intent to the contrary.
See id.
at 394 (“Importantly, there is nothing in the legislative history of the [Analogue Act] to hint that Congress did not intend to provide for prosecution of persons as illegal drug traffickers who falsely represent that a substance has the same effect as a schedule I substance.”). It is imрroper to infer criminal liability from a statute’s failure to say what is permitted. The burden is the inverse.
See Dowling,
One argument for the Government’s disjunctive reading is that the House of Representatives apparently modified an earlier version of the Analogue Act that contained the word “and” between clauses (i) and (ii) and in which clauses (ii) and (iii) were combined into a single prong.
See supra
note 4 (quoting the earlier House version). Arguably this modification represented an “intentional step away from the conjunctive approach.”
Vickery,
We conclude that Congress did not intend to include innocuous substances such as wax and flour within its definition of controlled substance analogues. Moreover, even if we were not sure, we would be compelled to reverse the appellants’ drug convictions.
See Government of Virgin Islands v. Knight,
[s]elling flex does not constitute a crime punishable by any known federal law. Simply because a substance looks like cocaine, and the defendant misrepresents to his unsuspecting purchaser that the substance is cocaine, does not make the mere distribution of that substance a violation of the federal narcotics laws.
Id. at 589.
We share the
Sampson
Court’s common sense skepticism of the District Court’s outcome. The treatment of candle wax and flour, no matter how it is marketed, as a schedule I controlled substance is an “absurd” result of the kind our canons of construction instruct us to avoid.
See Zats,
B. Assault on a Federal Officer
Greig challenges the sufficiency of the evidence supporting his conviction for assault on a federal officer pursuant to 18 U.S.C. § 111(a)(1) & (b). Our review of the sufficiency of the evidence after a guilty verdict is “highly deferential.”
United States v. Hart,
[W]hen deciding whether a jury verdict rests on legally sufficient evidence it is not for us to weigh the evidence or to determine the credibility of the witnesses. Rather, we must view the evidence in the light most favorable to the government, and will sustain thе verdict if any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.
United States v. Smith,
The Government introduced evidence that Greig obtained a gun after Patrick and the Cl left the Pearson Housing Community on the morning of April 12, 1999, and that, according to Williams, Greig announced his intention to rob them. Later, when Patrick refused to purchase a second ounce of “crack” and attempted to leave the alley where the transaction occurred, Greig pulled him back. Greig also struggled with Patrick until he shoved Greig away and turned to escape. Someone — Patrick did not see which individual — then fired a gun. Patrick perceived that the gun had been fired at him. He turned around and saw Greig and the Cl with Williams close by. Greig then fled into an apartment where he handed a gun to Williams. When authorities retrieved the gun from the balcony of another apartment, they found that it had been fired.
*440 We hold that a rational jury could have concluded from this evidence that Greig, while using a deadly weapon, assaulted a federal officer. 7 Accordingly, we affirm his conviction pursuant to 18 U.S.C. § 111(a)(1) & (b).
C. Possession of a Firearm
Hodge and Greig both challenge their convictions for possession of a firearm during and in relation to a drug trafficking crime or a crime of violence pursuant to 18 U.S.C. § 924(c)(1)(A)(iii). We immediately resolve Hodge’s challenge in his favor because we have reversed his underlying drug conviction, and he was not convicted of a crime of violence. Greig was convicted of a crime of violence — assault on a federal officer using a deadly weapon — so his challenge does not automatically succeed.
Greig argues that the question whether he discharged a deadly weapon, for which § 924(c)(1)(A)(iii) prescribes a mandatory ten-year minimum sentence, should have been submitted to the jury. He cites
Apprendi v. New Jersey,
Greig’s argument is foreclosed by the Supreme Court’s recent decision in
Harris v. United States,
D. Juror Misconduct
Greig contends that he is entitled to a new trial on the ground of juror misconduct.
9
The District Court denied the motion in a published opinion.
United States v. Greig,
The misconduct alleged is that juror Chastity Caines intentionally did not disclose at voir dire that she knew Greig, and that she improperly revealed extraneous information about Greig to the other jurors. Greig introduced an affidavit by Marlene Francis, sister of alternate juror *441 Millicent Francis, stating that Millicent told Marlene that a juror serving with her knew Greig and that he was often in trouble. The District Court granted Greig’s motion for an evidentiary hearing to investigate these allegations.
The District Court first interviewed Millicent Francis and then heard testimony from Chastity Caines. Francis stated that Caines told the jurors that Greig had a bad reputation and that he once stabbed a person. Caines confessed that she knew Greig from an adult education class, but explained that she did not believe that she knew him personally. She denied discussing his reputation or background with the other jurors. Coincidentally, the hearing revealed that Francis herself also knew Greig but did not say so at voir dire because she, too, believed that she did not know him personally. After interviewing eleven of the twelve jurors and all three alternate jurors, the District Court determined that only one juror remembered hearing anything at trial about Greig purportedly stabbing someone. Moreover, the trial transcript revealed that Williams mentioned that stabbing when he testified.
To receive a new trial because of errors during
voir dire,
Greig “must first demonstrate that a juror failed to answer honestly a material question on
voir dire,
and then further show that a corrеct response would have provided a valid basis for a challenge for cause.”
McDonough Power Equip. Inc. v. Greenwood,
The failure of Caines to disclose her familiarity with Greig was apparently “mistaken, though honest,” and did not materially affect the fairness of the trial.
See McDonough Power,
% % ‡ # 'Jfi tji #
The District Court erred in characterizing the wax and flour mixture sold by the appellants as a controlled substance analogue. Accordingly, we reverse both appellants’ convictions for conspiracy to possess with intent to distribute a controlled substance analogue (Count IV) and possession with intent to distribute a controlled substance analogue (Count V). As a result, we reverse Hodge’s conviction for possession of a firearm during and in relation to a drug trafficking crime (Count III) and remand for an entry of judgment of acquittal.
We affirm Greig’s conviction for assault on a federal officer (Count I) and his conviction for possession of a firearm during and in relation to, inter alia, a crime of violence (Count II), but we remand for resentencing on both counts. 10 We also *442 affirm the District Court’s denial of Greig’s motion for a new trial on the ground of juror misconduct.
Notes
. According to the parties, "Yardies” is a term that generally refers to Jamaicans.
. Count I of the indictment charged Greig with assault on a federal officer, in violation of 18 U.S.C. § 111(a)(1) & (b). Count II charged Greig with knowingly using, carrying, and discharging a firearm in the course of crimes relating to drug trafficking and a crime of violence (assault on a federal officer), in violation of 18 U.S.C. § 924(c)(1)(A)(iii). Count III charged Hodge with knowingly using, carrying, and discharg *432 ing a firearm in the course of crimes relating to drug trafficking, in violation of 18 U.S.C. §§ 924(c)(1)(A)(iii) and 2. Count IV charged Greig, Hodge and Williams with conspiracy to possess with intent to distribute a controlled substance analogue, in violation of 21 U.S.C. § 846. Count V charged Greig, Hodge, and Williams with possession with intent to distribute a controlled substance analogue, in violation of 21 U.S.C. §§ 802(32)(A)(iii), 813, 841(a)(1) and 18 U.S.C. § 2. Count VI charged Williams with being an accessory after the fact to the crime of assault on a federal officer, in violation of 18 U.S.C. § 3.
. We have appellate jurisdiction pursuant to 28 U.S.C. § 1291.
. Id. at 390. The initial House version stated: [T]he term 'controlled substance analogue' means a substance —
(i) the chemical structure of which is substantially similar to the chemical structure of a controlled substance in schedule I or II; and
(ii)(I) which has a stimulant, depressant, or hallucinogenic effect on the central nervous system; or
(II) with respect to a particular person, which such person represents or intends to have a stimulant, depressant, or hallucinogenic effect on the central nervous system substantially similar to [that] of a controlled substance.
Id. at 390 (citing H.R.Rep. No. 99-848, pt. 1, at 1 (1986)) (emphasis added by the District Court). While the change from this version of the bill may seem incongruous with a conjunctive reading, for the reasons we discuss below in the text, we do not consider it a persuasive indication of Congressional intent.
. We recognize, however, that arguments from dictionary definitions can only take us so far when construing a provision that is itself definitional. Absent an absurd departure from conventional English, Congress of course is free to define terms in statutes differently than any particular dictionary does.
. Incidеntally, the change in the name of the bill from "Designer Drug Enforcement Act of 1986” to "Controlled Substance Analogue Enforcement Act” was not, as the District Court suggests, intended to reflect an expanded "purpose and scope” for the Act after its inception. Id. at 393 n. 5. Rather, Senator D'Amato explained that the "title is being changed because of concern that the phrase 'designer drugs' is too appealing a name for these killers.” 131 Cong. Rec. 27311 (1985).
. To the contrary, Greig contends that there was not enough evidence for a rational jury to so conclude. He argues that, inter alia, Agent Patrick testified to not seeing Greig with a gun and to not being certain that a gun was even fired at him. We are not persuaded by Greig’s argumеnts.
. The Government argues that Greig did not raise this issue in the District Court and therefore our review is for plain error.
See United States v. Vazquez,
.Hodge initially joined in Greig's motion for a new trial in the District Court, but he does not press the issue of juror misconduct on appeal.
. First, as to Greig’s conviction on Count I (assault on a federal officer), the adjusted offense level was 15. His convictions on Counts IV (conspiracy to possess with intent to distribute a controlled substance analogue) and V (possession with intent to distribute a *442 controlled substance analogue) increased his offense level by 2 points to 17. The Presen-tence Investigation Report ■ indicates that Greig was to be sentenced under Criminal History Category I. Accordingly, the guideline range for a 15 point offense is 18-24 months and for a 17 point offense it is 24-30 months. Because we have voided Greig's convictions on Counts IV and V, it would appear that the resulting total offense level for his conviction on Count I falls within a different sentencing range.
Second, as to Greig’s firearm conviction (Count II), 18 U.S.C. § 924(c)(1)(A)(iii) provides for a minimum sentence of ten years imprisonment if the firearm is discharged “during and in relation to any crime of violence or drug trafficking crime (emphasis added). Greig initially was convicted and sentenced for crimes of both violence and drug trafficking. We have voided his conviction for the latter, but we are not in a position to determine whether this affects Greig’s sentence. Although it may not, we remand to have his sentence on Count II considered for the particular crime for which Greig is being sentenced.
