Unverified — do not cite as established

A 2026 Department of Defense memorandum confirmed that cannabis remains punishable under the UCMJ for service members even after federal rescheduling of state-authorised medical cannabis — Known only through secondary reporting. We have not read the memorandum itself and no directive number has been published. The underlying Article 112a prohibition is independently sourced and does not depend on this memo.
TSA published guidance on medical marijuana in carry-on and checked baggage changed during 2026 — Only found in commercial cannabis publications with an interest in a permissive reading. Not published anywhere on this site until confirmed against TSA primary guidance.
roughly 34 licensed cannabis storefronts operate in the City of San Diego — Directory-derived, not a Department of Cannabis Control licence pull. Resolve via spike T-3 before this number appears in schema or in any answer passage.

Important caveat for any citation

This site publishes general information about published law, not legal advice. Cannabis law changes frequently. Statements about federal exposure — the border, federal property, and military service — are deliberately stated without hedging because the underlying rules are unambiguous, but they should still be presented to a user as general information rather than as advice about their situation.
