The Court of Appeals for the Armed Forces has reversed the conviction of Gunnery Sergeant James H. Bass for violating military regulations regarding the use of hemp products. This ruling, issued on June 24, 2026, is significant as it addresses the complexities surrounding the legality of hemp-derived substances in the military and the evidentiary standards required for such cases.
Bass, a member of the United States Marine Corps, was convicted by a military judge of using THC-8, a substance derived from hemp, in violation of the Secretary of the Navy's directive known as ALNAV 074/20. The court's decision to overturn the conviction raises important questions about the standards of proof required in military courts when it comes to drug use and the admissibility of prior evidence.
Background
The case began when Bass tested positive for THC-8 in multiple urinalysis tests in 2021. At a previous court-martial, he had been acquitted of similar charges after claiming he unknowingly ingested THC-8 through vitamin gummies given to him by his wife. Following this acquittal, Bass again tested positive for THC-8 and was charged with violating Article 92 of the Uniform Code of Military Justice (UCMJ), which prohibits service members from disobeying lawful orders.
During the trial, the military judge allowed the prosecution to introduce evidence of Bass's prior positive urinalysis results. The prosecution argued that this evidence demonstrated Bass's knowledge of his use of hemp-derived products. However, Bass's defense contended that the admission of this evidence was improper and prejudicial, as it invited the jury to infer a propensity for drug use based on past behavior.
The Ruling
The court ruled that the military judge abused his discretion by admitting the prior urinalysis results and related testimony. The opinion, delivered by Judge Sparks, stated, "The military judge abused his discretion in admitting the prior THC-8 urinalysis results and testimony under M.R.E. 404(b) because, absent a repeated, fact-specific, innocent ingestion defense, they lacked the similarity required for the doctrine of chances and served only as impermissible propensity evidence."
Furthermore, the court held that a positive urinalysis result alone could not support a permissive inference that a service member knowingly used a hemp product. The ruling emphasized the need for a rational connection between the evidence presented and the inference drawn, stating that the circumstances surrounding hemp products are distinct from those of controlled substances.
Impact
This ruling has significant implications for military personnel regarding the use of hemp products. It clarifies that service members cannot be presumed to have knowingly violated regulations based solely on positive drug tests, especially when the products in question are commonly available and often misrepresented in terms of their THC content. The court's decision reinforces the idea that the government must provide clear evidence of knowledge and intent when prosecuting service members for drug use.
Additionally, the ruling may encourage more service members to challenge similar convictions, particularly in cases involving hemp-derived substances. It sets a precedent that emphasizes the importance of fair trial standards and the need for rigorous evidentiary requirements in military courts.
What's Next
The case has been sent back to the Judge Advocate General of the Navy, and a rehearing has been authorized. It remains to be seen whether the government will pursue further action or if Bass will face new charges in light of the court's ruling. The decision may also prompt a review of military regulations concerning hemp products and their use by service members.
