Can You Fly With CBD or Cannabis? TSA and Federal Law

Where these numbers come from

TSA's role is aviation security, not drug enforcement, and its cannabis page says so directly: officers do not go looking for marijuana or other illegal drugs. The catch is that if screening turns something up, TSA refers it to a law enforcement officer, and officers must report suspected violations to local, state or federal authorities. So the fact that a bag is not searched for cannabis does not mean the contents are cleared.

What is legal depends on federal law, because every commercial flight is under federal jurisdiction, even between two states where cannabis is legal. TSA states that marijuana and certain cannabis-infused products, including some CBD oil, remain illegal under federal law, with two exceptions: products containing no more than 0.3 percent THC on a dry weight basis, and products approved by the FDA. A hemp CBD tincture that meets the 0.3 percent line sits on the legal side. A dispensary product above that line does not, whatever the state says.

A labeled example helps. A 30 ml hemp CBD oil bottle rated 0.3 percent THC or less is federally legal, and because 30 ml is under the 100 ml limit it fits in the quart bag for a carry-on. A 120 ml bottle of the same oil must go in a checked bag. Keep the product in its original package with the lab report or certificate of analysis so you can show the THC content if asked. A gummy, vape cartridge or topical has its own status, but the THC percentage and the origin still decide the legal side.

State and destination laws add another layer. A product that is fine in your departure state can be illegal where you land, and some countries treat CBD as a controlled drug, so check the destination before you fly. TSA does not confirm your THC percentage at the checkpoint. If you use cannabis-related vape devices, also review the e-cigarette and vape rules, which prohibit them in checked bags, and the medications page for prescription items.
