U.S. Navy Bans Kratom, Mitragynine, and 7-OH: Sailors Face UCMJ Action for Use

Why it matters

The Navy's ban exposes sailors to UCMJ disciplinary action for using a substance still legal in most U.S. states, setting a formal military policy precedent and reflecting growing concern about kratom's safety risks in high-readiness personnel.

The big picture

Federal agencies have not yet banned kratom nationally, but individual armed services branches are taking matters into their own hands. The Navy's January 2026 directive follows growing evidence that 7-hydroxymitragynine can be more potent than morphine. The Coast Guard issued a similar ban in May 2026, suggesting a broader military-wide trend toward zero-tolerance kratom policies.

Key findings

• Navy issued a Jan. 14, 2026 service-wide ALNAV message banning kratom, mitragynine, and 7-hydroxymitragynine
• Violators face administrative and/or disciplinary action under UCMJ Article 92 for failure to obey a lawful general order
• The Navy cited specific risks including seizures, tachycardia, hepatotoxicity, hypertension, and death
• The FDA does not federally regulate kratom but has moved to classify 7-OH as a controlled substance
• Sailors with substance use concerns were referred to the Navy's Substance Abuse Rehabilitation Program

What they say

"Protecting service member welfare and readiness is paramount to maintaining an effective fighting force. Substance misuse by members of the armed forces is incompatible with military standards of good order, discipline, performance, and operational readiness." — U.S. Navy ALNAV message, January 2026

Bottom line

Any sailor found using kratom — still legal in most states — now faces potential UCMJ disciplinary action under the Navy's January 2026 ban.
