As the legalization of cannabis spreads across America, the medicinal use of cannabis now legal in 33 states, and adult recreational use of cannabis now legal in 11 states, it raises questions around traveling with the substance. Until recently, TSA has been firm that traveling with any form of the plant is illegal. But new guidelines released by the federal branch loosen previous restrictions, allowing passengers to bring products that contain hemp-derived CBD oil or are FDA-approved.

CBD, which stands for cannabidiol, is a naturally occurring compound found in the resinous flower of cannabis. CBD is a safe, non-addictive substance and unlike THC does not have a psychoactive effect, meaning, it will not get you high. The compound has a host of benefits, treating everything from seizures, and anxiety, to chronic pain and depression. It’s also become a popular ingredient in beauty products, hailed for its anti-inflammatory and moisturizing components.

TSA said the change in its policy was prompted by the only FDA-approved drug that contains CBD oil, Epidiolex, which is used to treat seizures in children with epilepsy. TSA’s guidance on flying with medical marijuana now reads:

Possession of marijuana and certain cannabis-infused products, including some Cannabidiol (CBD) oil, remain illegal under federal law. TSA officers are required to report any suspected violations of law, including possession of marijuana and certain cannabis-infused products.

Products/medications that contain hemp-derived CBD or are approved by the FDA are legal as long as it is produced within the regulations defined by the law under the Agriculture Improvement Act 2018.
