U.S. Airport Security Guidelines and Marijuana Travel Restrictions

The Transportation Security Administration (TSA) advises travelers to prepare for airport checkpoints by using trusted‑traveler programs such as TSA PreCheck, ensuring identification is in order, packing bags with security rules in mind, and verifying reservation details. PreCheck can speed screening by allowing shoes, belts and light jackets to remain on and permitting liquids and laptops to stay in carry‑on bags.

Under federal law, recreational marijuana remains illegal and the TSA, which enforces federal regulations, treats it as a prohibited item. Medical marijuana was reclassified to Schedule III, and the TSA says it may be carried in checked or carry‑on baggage with “special instructions,” though those instructions are not detailed. Most major airlines also forbid any marijuana on board. Travelers found with marijuana may face confiscation, fines, or other enforcement actions depending on the amount, medical status, and state laws.
