How Does the UCMJ Address Drug Offenses in the Military?
On this page
Article 112a of the UCMJ (10 U.S.C. § 912a) makes it an offense to wrongfully use, possess, manufacture, distribute, import, export, or introduce onto military property a controlled substance. The term “wrongful” means without legal justification or authorization, and knowledge of the substance’s presence is part of wrongful use. A positive urinalysis, explained by expert testimony, permits but does not require an inference of knowing, wrongful use. Maximums range from 2 to 15 years, plus 5 more in listed aggravating settings. Hemp and CBD products are prohibited separately by service regulations.
What Article 112a covers
The statute names “Opium, heroin, cocaine, amphetamine, lysergic acid diethylamide, methamphetamine, phencyclidine, barbituric acid, and marijuana and any compound or derivative of any such substance”, plus substances the President lists and substances on Schedules I through V of the Controlled Substances Act (§ 912a(b)). Each act (use, possession, manufacture, distribution, importation, exportation, introduction, and possession, manufacture, or introduction with intent to distribute) is a separate offense.
Use means “to inject, ingest, inhale, or otherwise introduce into the human body, any controlled substance.” The Manual adds: “Knowledge of the presence of the controlled substance is a required component of use” (MCM 2024, Part IV, ¶50.c(10)).
Deliberate ignorance. “An accused who consciously avoids knowledge of the presence of a controlled substance or the contraband nature of the substance is subject to the same criminal liability as one who has actual knowledge” (¶50.c(11)).
Wrongfulness and its exceptions
Under ¶50.c(5), drug conduct “is wrongful if it is without legal justification or authorization.” Possession, distribution, introduction, or manufacture is not wrongful if done:
- in legitimate law enforcement activities (for example, an informant receiving drugs in an undercover operation);
- by authorized personnel in the performance of medical duties; or
- without knowledge of the contraband nature of the substance.
Wrongfulness “may be inferred … in the absence of evidence to the contrary.” The accused bears the burden of going forward with evidence of an exception; once the evidence raises it, “the burden of proof is upon the United States to establish that the use, possession, distribution, manufacture, or introduction was wrongful.”
What a positive urinalysis proves
Knowledge “may be inferred from the presence of the controlled substance in the accused’s body or from other circumstantial evidence”, and this “permissive inference may be legally sufficient to satisfy the Government’s burden of proof as to knowledge” (¶50.c(10)). The factfinder may draw the inference but is not required to.
The Court of Appeals for the Armed Forces’ digest records how courts handle the scientific foundation:
- Expert interpretation. In United States v. Green, 55 M.J. 76 (2001), the court held that where scientific evidence is the sole basis to prove wrongful use, “expert testimony interpreting the tests or some other lawful substitute in the record is required” to give the factfinder a rational basis for the inference. The military judge may consider whether the metabolite is produced only by the drug in question, whether the inference is appropriate given the cutoff level and the reported concentration, and whether the testing method is reliable, and “must ensure a careful and thorough Daubert-type analysis”.
- Other ways to prove it. In United States v. Campbell, 52 M.J. 386 (2000) (on reconsideration), the court held that this three-part approach is not the only means of proving knowing use, and that the expert testimony need not be tailored to the individual but may support the inference “with respect to human beings as a class”.
- Knowledge is required. In United States v. Webb, 66 M.J. 89 (2008), the court stated that “knowledge of the presence of the controlled substance is a required component of wrongful use”.
Innocent ingestion. A claim that the accused did not know a substance was present attacks the knowledge element; evidence supporting it puts the burden on the government to prove wrongfulness beyond a reasonable doubt.
How the sample is obtained
An order to produce urine is permissible as part of an inspection under Military Rule of Evidence 313(b)(1), which does not require probable cause. A collection whose primary purpose is to obtain evidence for a court-martial is not an inspection. When an examination to locate contraband follows a report of a specific offense and was not previously scheduled, singles out specific individuals, or subjects persons to substantially different intrusions, the prosecution must prove by clear and convincing evidence that it was a genuine inspection (M.R.E. 313(b)(3)(B)). Other collection routes include consent and probable cause authorizations; see how search and seizure rules apply in the military.
Maximum punishments
| Offense | Substance | Manual maximum (¶50.d) |
|---|---|---|
| Use, possession, manufacture, or introduction | Listed drugs (except marijuana use or possession under 30 grams), secobarbital, Schedules I-III | DD, total forfeitures, 5 years |
| Use, possession, manufacture, or introduction | Marijuana (use, or possession under 30 grams), phenobarbital, Schedules IV-V | DD, total forfeitures, 2 years |
| Distribution; possession, manufacture, or introduction with intent to distribute; importation or exportation | Listed drugs (including marijuana), secobarbital, Schedules I-III | DD, total forfeitures, 15 years |
| Same | Phenobarbital, Schedules IV-V | DD, total forfeitures, 10 years |
The confinement maximum increases by 5 years when the offense is committed while on duty as a sentinel or lookout; aboard a military vessel or aircraft; at a military missile launch facility; while receiving special pay under 37 U.S.C. § 310; in time of war; or in a military confinement facility (¶50.d). When all findings of guilty are for offenses committed after December 27, 2023, the military judge sentences within the applicable sentencing parameter beneath these maximums.
Hemp, CBD, and state legalization
Hemp and CBD. Although federal law removed low-THC hemp from the definition of a controlled substance, a Department of Defense memorandum of February 26, 2020, effective March 1, 2020, and service regulations prohibit using hemp-derived products. For example, Navy policy (ALNAV 074/20) prohibits Sailors and Marines from using “any product made or derived from hemp … including CBD, regardless of the product’s THC concentration, claimed or actual, and regardless of whether such product may lawfully be bought, sold, and used under the law applicable to civilians”, with exceptions for prescribed FDA-approved drugs and durable goods; Coast Guard, Army (AR 600-85), and Air Force (DAFMAN 44-197) policies contain similar prohibitions, and the Coast Guard text states that it “does not apply to the use of durable goods containing hemp, such as rope or clothing” (Operation Supplement Safety, Department of Defense). A violation of such a regulation can be charged as failure to obey a lawful general order or regulation under Article 92. If a product contains enough THC to produce a positive test, the Article 112a questions about knowledge and wrongfulness apply.
State marijuana laws. Marijuana is named in Article 112a itself. A state’s legalization does not change the UCMJ, which applies to service members in all places (Article 5).
Beyond the criminal case
A positive test can lead to administrative action, including separation processing (administrative separation versus court-martial), separate from any court-martial.
