Rumors circulating in May 2026 suggested the U.S. Transportation Security Administration (TSA) had updated its rules to allow medical marijuana in both carry-on and checked luggage. However, a Snopes investigation found the claim to be misleading.

While the TSA did revise its website in April, removing some references to federal cannabis laws, the agency confirmed its policy has not changed since at least 2019. Medical marijuana is only permitted if it complies with federal regulations, which still classify most cannabis products as illegal.

TSA officers focus on security threats rather than actively searching for drugs, but any illegal substances discovered may be referred to law enforcement. The final decision ultimately rests with the screening officer.
