ACCA Predicate Drug Offenses in Georgia: Incorporation of Federal Drug Schedules Defeats “Broader Cocaine Definition” Overbreadth Challenges

1. Introduction

In United States v. Emory Austin Carter (11th Cir. 2026), the Eleventh Circuit considered whether four prior Georgia cocaine-distribution convictions could qualify as “serious drug offense[s]” triggering the Armed Career Criminal Act (“ACCA”) 15-year mandatory minimum for a felon-in-possession conviction under 18 U.S.C. §§ 922(g)(1) and 924(e)(1).

The core dispute was categorical: Carter argued that Georgia’s statutory definition of “cocaine” is broader than the federal definition because Georgia referenced “any … stereoisomers of cocaine,” while federal law referenced only “optical and geometric isomers.” Carter supported this argument with an expert chemistry declaration positing that “conformational isomers” could exist and could fall within Georgia’s “stereoisomers” wording but outside the federal schedule.

Carter also pressed a separate “ioflupane” mismatch argument, contending that because federal scheduling later excluded ioflupane, Georgia cocaine convictions should not count as ACCA predicates—at least when measured against the federal schedules at the time of federal sentencing.

2. Summary of the Opinion

The Eleventh Circuit affirmed the 210-month sentence and held that Carter’s Georgia cocaine-distribution convictions qualify as ACCA “serious drug offense[s].” Even assuming textual differences between Georgia’s and federal cocaine definitions, the court concluded those differences do not create any “actual legal consequences” under Georgia law because Georgia defines “controlled substance” to include only drugs listed on both Georgia and federal schedules, as authoritatively interpreted by the Georgia Court of Appeals in C.W. v. Dep’t of Human Servs..

The court also rejected Carter’s ioflupane argument because Brown v. United States requires using the federal schedules in effect when the defendant committed the state drug offense (not the schedules in effect at the later federal sentencing), and in any event Georgia’s “both schedules” rule defeats the mismatch theory.

3. Analysis

3.1. Precedents Cited

  • United States v. Jackson, 55 F.4th 846 (11th Cir. 2022), aff’d sub nom., Brown v. United States, 602 U.S. 101 (2024): Provided the baseline ACCA categorical-approach framework and the “match” requirement between state drug definitions and federal schedules at the time of the state offense. The Carter panel treated this as the settled “major premise” of Carter’s syllogism: overbroad state drug statutes cannot serve as ACCA predicates.
  • Brown v. United States, 602 U.S. 101 (2024): Foreclosed Carter’s ioflupane timing theory by requiring reference to the federal schedules “at the time the defendant committed his state-law drug crime.”
  • United States v. Laines, 69 F.4th 1221 (11th Cir. 2023): Reinforced that, under the categorical approach, “all the controlled substances covered by the state [statute] must also be controlled substances under federal law.” Carter extends this principle by emphasizing that state-law incorporation of the federal schedules can eliminate overbreadth in practical legal effect.
  • C.W. v. Dep’t of Human Servs., 836 S.E.2d 836 (Ga. Ct. App. 2019): The pivotal state-law authority. It interpreted O.C.G.A. § 16-13-21(4)’s definition of “controlled substance” to require a drug be listed “in both Georgia and federal schedules.” Carter treats this as dispositive: if a substance is not federally scheduled, then it is not a “controlled substance” under Georgia law, regardless of how a Georgia drug definition reads in isolation.
  • Deference-to-state-law line of cases—EmbroidMe.com, Inc. v. Travelers Prop. Cas. Co. of Am.; Mullaney v. Wilbur; Pinkney v. Secretary, DOC; In re Cassell; United States v. Rosales-Bruno: Used to justify treating Georgia appellate courts as authoritative expositors of Georgia statutory meaning, including for ACCA element analysis.
  • Intermediate-appellate-court binding effect—King v. Ord. of United Com. Travelers of Am.; United States v. Hill; CSX Transp., Inc. v. Gen. Mills, Inc.; Flintkote Co. v. Dravo Corp.: Supported the court’s reliance on C.W. absent “persuasive evidence” the Georgia Supreme Court would disagree.
  • Realistic probability doctrine—Gonzales v. Duenas-Alvarez; Chamu v. U.S. Att’y Gen.; Ramos v. U.S. Att’y Gen.: Provided the “realistic probability, not a theoretical possibility” requirement and Carter’s key move: even where text differs, a defendant must show those differences have “actual legal consequences.”
  • Burden of proof at ACCA sentencing—United States v. Harris: Acknowledged that the government bears the burden to justify the enhancement, but held that, regardless of burden allocation, Georgia law made Carter’s overbreadth theory legally impossible.
  • Standard of review—United States v. White: Confirmed de novo review for whether a prior conviction qualifies as an ACCA serious drug offense.
  • Second Amendment foreclosing precedent (mentioned but not reached on the merits)—United States v. Hicks; United States v. Dubois: Disposed of Carter’s separate § 922(g)(1) constitutional challenge.

3.2. Legal Reasoning

The court accepted the ACCA categorical-approach “matching” framework but rejected Carter’s premise that Georgia’s cocaine definition can be evaluated without considering Georgia’s separate statutory definition of “controlled substance.” Carter’s analysis focused on the cocaine-definition provision (O.C.G.A. § 16-13-26(1)(D)), but his actual statutes of conviction (O.C.G.A. § 16-13-30(b)) criminalize distribution (and possession with intent) of a “controlled substance,” and O.C.G.A. § 16-13-21(4) defines that term conjunctively by reference to Georgia schedules and federal schedules.

The opinion’s operative reasoning proceeds in three steps:

  1. Identify the statutory “gatekeeper” element under Georgia law. Georgia prosecutes the relevant conduct only when the substance is a Georgia “controlled substance.”
  2. Apply authoritative state-court interpretation of the gatekeeper definition. Under C.W. v. Dep’t of Human Servs., a substance qualifies as “controlled” in Georgia only if it appears on both state and federal schedules.
  3. Conclude that claimed state overbreadth is legally inert. If “conformational isomers” (or other forms) are not federally scheduled, they are not “controlled substances” in Georgia, so they cannot be the basis of a Georgia conviction under O.C.G.A. § 16-13-30(b). Thus, even assuming the cocaine-definition text is broader, there is no “realistic probability” of broader prosecution and no “actual legal consequences.”

Notably, the panel framed Carter’s argument as a syllogism and agreed with the “major premise” (overbroad state definitions generally fail the ACCA match), but deemed the “minor premise” false because Georgia law—properly understood through O.C.G.A. § 16-13-21(4) and C.W.—precludes convictions based on substances not federally scheduled.

The court also neutralized Carter’s attempt to leverage chemistry testimony. The expert declaration could at most suggest a theoretical textual mismatch between “stereoisomers” and “optical and geometric isomers,” but it could not create a legally cognizable mismatch under the categorical approach because Georgia law independently requires federal scheduling. In the court’s terms, this was precisely what Chamu v. U.S. Att’y Gen. warns against: “Different words alone are not enough.”

3.3. Impact

Immediate doctrinal effect in Georgia ACCA litigation. Carter significantly strengthens the government’s position in ACCA (and potentially guidelines) litigation involving Georgia drug predicates: defendants cannot establish overbreadth by isolating Georgia’s drug-definition language where the statute of conviction requires the substance to be a Georgia “controlled substance,” and Georgia defines that term to include federal schedules conjunctively.

Broader categorical-approach significance. The decision illustrates a general analytic template: when evaluating “controlled substance” predicates, courts must examine the full state-law element structure (including definitional cross-references and scheduling-incorporation provisions), not merely the standalone definition of the named drug. Carter also highlights how the “realistic probability” inquiry can be resolved as a matter of state law when a state appellate decision makes the claimed overbreadth legally impossible.

Timing disputes after Brown. Carter applies Brown v. United States to reject using federal schedules at the time of federal sentencing, reinforcing that post-offense federal scheduling changes (like the ioflupane exclusion) do not retroactively alter ACCA predicate status for earlier state offenses.

Limits and open questions. Carter’s reasoning is tightly tied to Georgia’s unusual “both schedules” definition as interpreted in C.W.. Other states that incorporate federal schedules differently (e.g., dynamically, or disjunctively, or not at all) may not be affected. Additionally, the opinion does not deeply engage divisibility/modified categorical approach questions because Georgia’s “controlled substance” requirement resolved the claimed mismatch categorically.

4. Complex Concepts Simplified

ACCA “serious drug offense”
A prior state drug conviction can trigger ACCA’s 15-year mandatory minimum if it involves manufacturing/distributing/possessing with intent to distribute a federally controlled substance and carries a sufficiently high maximum penalty.
Categorical approach
Courts compare the elements of the prior offense (what the statute requires to convict), not the defendant’s actual conduct. If the statute criminalizes a broader set of conduct than ACCA covers, the conviction cannot count as a predicate.
“Realistic probability”
A textual possibility is not enough; the defendant must show the state actually could apply the statute to non-generic conduct. Carter holds that when state law itself forecloses broader applications, there is no realistic probability of mismatch.
Isomers and the “stereoisomer” dispute
“Isomers” are molecules with the same formula but different structure. Carter’s expert suggested “conformational isomers” are a type of stereoisomer distinct from “optical” and “geometric” isomers. The court’s key point was legal, not chemical: Georgia law would not treat a non-federally scheduled isomer as a “controlled substance” anyway.
Incorporation of federal schedules (“and” vs. “or”)
Georgia defines “controlled substance” to include substances listed in Georgia schedules and in federal schedules. Under C.W. v. Dep’t of Human Servs., that “and” means both lists must include the substance.

5. Conclusion

United States v. Emory Austin Carter establishes (for Eleventh Circuit purposes) a powerful answer to “Georgia cocaine definition is broader” ACCA challenges: because Georgia’s definition of “controlled substance” requires a drug to be listed on both Georgia and federal schedules (per C.W. v. Dep’t of Human Servs.), Georgia cocaine-distribution convictions cannot rest on substances outside federal control, eliminating any meaningful categorical mismatch even where drug-definition wording differs. The decision also reinforces Brown v. United States on timing—federal schedules are assessed as of the state-offense date—and exemplifies how state-law interpretive authority and the “realistic probability” doctrine can decisively resolve categorical disputes.
