Usable Multi-Drug “Mixture” Sentencing: Entire Weight Counts and Is Assigned to the Drug Producing the Higher Offense Level Absent Unusable Waste

Introduction

In United States v. Anthony Edward Jackson (11th Cir. Apr. 9, 2026) (unpublished), the Eleventh Circuit affirmed a 128-month sentence imposed after Jackson’s conviction for possession with intent to distribute controlled substances under 21 U.S.C. § 841(a)(1). The appeal raised two issues:

Whether the government failed to prove that a multi-drug powder mixture (containing heroin, fentanyl, and methamphetamine, plus certain noncontrolled substances) was “marketable as fentanyl,” such that its full weight could be treated as fentanyl for guideline calculations.
Whether the resulting 128-month sentence was substantively unreasonable under 18 U.S.C. § 3553(a).

The panel’s core holding is practical: when a seized mixture is a usable drug mixture containing multiple controlled substances, the Guidelines’ mixture rule applies as written—the entire weight is counted and assigned to the controlled substance producing the greater offense level; the defendant cannot invoke “unusable waste” precedents without actually identifying unusable material.

Summary of the Opinion

The Eleventh Circuit affirmed on both issues.

Drug-weight/mixture issue: The district court did not clearly err in attributing the full weight of a uniform powder mixture (1,659.89 grams) to fentanyl for guideline purposes. The court relied on the Guidelines’ mixture rule and testimony that traffickers cut drugs and can present such mixtures as fentanyl or heroin, and that buyers seeking fentanyl or heroin would purchase the mixture. Because fentanyl yielded the higher base offense level, the Guidelines directed using fentanyl.
Substantive reasonableness: The 128-month sentence—within the 121–151 months guideline range and below the statutory maximum of life—was not an abuse of discretion. Jackson’s sentencing-disparity claim failed for lack of a valid comparator, and the district court permissibly weighed his criminal history and personal characteristics (including mental/physical health).

Analysis

Precedents Cited

1) Guideline application and mixture-weight principles

United States v. Azmat, 805 F.3d 1018, 1046 (11th Cir. 2015): supplied the clear error standard for drug-quantity findings. The panel used this framework to uphold the district court’s factual determination about attributing the mixture’s weight.
United States v. Arguedas, 86 F.3d 1054, 1059 (11th Cir. 1996): provided de novo review for application of the Guidelines to established facts—i.e., once the mixture’s nature/weight is found, the legal step of how to apply § 2D1.1 is reviewed anew.
Chapman v. United States, 500 U.S. 453, 468 (1991): the Supreme Court’s foundational “mixture or substance” case, emphasizing “street weight” (diluted form) rather than purity. Jackson’s panel invoked Chapman to reinforce the general rule that the whole mixture weight counts where the mixture is the form distributed.
United States v. Rolande-Gabriel, 938 F.2d 1231, 1236 (11th Cir. 1991): recognized limits to Chapman where the mixture includes unusable waste. The panel distinguished this line because Jackson did not identify unusable materials in the seized mixture.
United States v. Jackson, 115 F.3d 843, 848 (11th Cir. 1997): another limiting case addressing materials that are not cutting agents (e.g., “bricks of sugar”) and therefore should not automatically be treated as part of the drug mixture. The panel again found it inapposite because the record showed a uniform powder containing controlled substances and common adulterants/cutting agents.

2) Substantive-reasonableness framework

Gall v. United States, 552 U.S. 38, 41 (2007): established deferential abuse-of-discretion review of substantive reasonableness considering the totality of circumstances.
United States v. Rosales-Bruno, 789 F.3d 1249, 1256 (11th Cir. 2015): articulated the Eleventh Circuit’s three-part description of substantive unreasonableness (failing to consider key factors, weighing improper factors, or clear error of judgment in weighing proper factors), and reiterated that district courts may attach greater weight to some § 3553(a) factors than others.
United States v. Riley, 995 F.3d 1272, 1279 (11th Cir. 2021): reinforced that weight assigned to a § 3553(a) factor is committed to district-court discretion.
United States v. Tome, 611 F.3d 1371, 1378 (11th Cir. 2010): placed the burden on the appellant to show unreasonableness under the record and § 3553(a).
United States v. Osorto, 995 F.3d 801, 823 (11th Cir. 2021): supported the proposition that a within-Guidelines sentence is generally reasonable.
United States v. Jayyousi, 657 F.3d 1085, 1118 (11th Cir. 2011): treated a sentence well below the statutory maximum as an indicator of reasonableness.
United States v. Docampo, 573 F.3d 1091, 1102 (11th Cir. 2009): required a meaningful comparator to sustain an “unwarranted disparity” argument.

Legal Reasoning

1) The “mixture” rule and why Jackson’s “marketability” argument failed

The operative guideline provision was U.S.S.G. § 2D1.1(c), note (A), which states (in substance) that, unless otherwise specified, the relevant weight is the entire weight of any mixture containing a detectable amount of a controlled substance; and if the mixture contains more than one controlled substance, the entire weight is assigned to the drug producing the greater offense level.

The panel treated Jackson’s reliance on United States v. Rolande-Gabriel and United States v. Jackson as a category error: those cases address circumstances where part of the seized mass is unusable (waste) or plainly not a cutting agent (e.g., separable sugar), such that counting the whole mass would not reflect the “mixture or substance” concept.

Here, by contrast, the record described a uniform powder containing heroin (7.1%) and fentanyl (2.4%) and methamphetamine, plus noncontrolled substances (e.g., caffeine, lidocaine, dimethyl sulfone) commonly mixed with controlled substances. Crucially, Jackson did not identify any portion that was unusable waste or otherwise should be excluded. On that record, the district court’s factual determination was not clearly erroneous, and the Guidelines’ legal directive—assign the full weight to the drug producing the higher offense level—was correctly applied.

The opinion also notes testimony from a DEA case agent that traffickers cut products and can present the resulting mixture as one of the drugs within it, and that buyers seeking fentanyl or heroin would purchase it. That testimony functioned as additional support for treating the mixture as a usable, distributable drug product rather than as waste or packaging.

2) Why the 128-month sentence was upheld as substantively reasonable

Applying Gall v. United States and United States v. Rosales-Bruno, the panel emphasized traditional reasonableness markers:

The sentence fell within the correctly calculated 121–151 month guideline range.
It was well below the statutory maximum of life imprisonment.
The claimed disparity was unsupported because Jackson provided no comparator as required by United States v. Docampo.
The district court considered individualized factors, including extensive criminal history and health-related personal characteristics.

Jackson’s argument that a mandatory minimum would have been sufficient essentially asked the appellate court to reweigh the § 3553(a) factors—something the abuse-of-discretion standard generally forbids absent a clear error of judgment or reliance on improper considerations.

Impact

Although designated “NOT FOR PUBLICATION” (and thus not binding precedent), the decision is instructive in at least three ways for future sentencing disputes in multi-drug mixture cases:

Clarifying the proper target of “unusable waste” challenges: A defendant seeking to avoid counting the full mixture weight must squarely argue—and support with evidence—that some portion is unusable or not truly part of the drug mixture (as in United States v. Rolande-Gabriel and United States v. Jackson). Mere assertions about “marketability” do not substitute for an unusability showing.
Reinforcing Note (A)’s assignment rule in multi-drug mixtures: Where more than one controlled substance is present in a usable mixture, the entire weight is attributed to the drug that yields the higher base offense level—here, fentanyl. This creates a strong incentive for litigants to focus on whether the mixture contains excluded material, not on purity percentages alone.
Sentencing-disparity arguments remain comparator-driven: The panel reiterates that generalized disparity claims rarely succeed without a specific, similarly situated comparator record (United States v. Docampo).

Complex Concepts Simplified

“Mixture or substance” (drug-weight rule): For many drug guidelines, sentencing is based on the total weight of a mixed substance containing any detectable amount of the drug—often reflecting “street weight,” not pure drug content (Chapman v. United States).
“Unusable waste”: A judicially recognized limit where part of what is seized is not a usable, consumable, or distributable drug mixture (e.g., waste liquid or other unusable material), and thus should not increase sentencing weight (United States v. Rolande-Gabriel).
“Cutting agent” vs. separable non-drug material: Cutting agents/adulterants are substances mixed into drugs to dilute or modify them (often still part of the distributed product). In contrast, separable materials that are not part of a drug mixture (e.g., “bricks of sugar” used to conceal) may be excluded from the weight calculation (United States v. Jackson).
Substantive reasonableness: Whether the sentence is “too much” or “too little” given the § 3553(a) factors, reviewed deferentially for abuse of discretion (Gall v. United States). Appellate courts do not re-sentence; they check for serious weighing errors or improper considerations.

Conclusion

United States v. Anthony Edward Jackson affirms a straightforward application of U.S.S.G. § 2D1.1(c), note (A) in a multi-drug mixture: when the seized substance is a usable mixture containing more than one controlled substance, the Guidelines direct counting the entire weight and assigning it to the drug that produces the greater offense level. Attempts to invoke “unusable waste” limitations must be grounded in a concrete showing of unusability, not merely in disputes about “marketability” or low purity. On reasonableness review, the decision reiterates familiar Eleventh Circuit themes: within-Guidelines sentences are generally upheld, disparity arguments require comparators, and district courts retain broad discretion in weighing § 3553(a) factors.
