According to the Transportation Security Administration (TSA), the only cannabis-related products that are legal to bring onto a plane (in either carry-ons or checked baggage) are those that contain no more than 0.3 percent THC or medication that has been approved by the FDA.

In 2026, the question of where to put cannabis edibles—whether in a suitcase or carry-on—is fraught with legal complexity because cannabis remains federally illegal in the United States, even if you are traveling between two "legal" states. TSA’s primary focus is on security and threats, not drugs; however, if a TSA officer discovers what they suspect to be marijuana during screening, they are required by federal law to refer the matter to local law enforcement. Placing them in a carry-on increases the chance of discovery during the X-ray or a random bag search. While checked suitcases are also screened, they are less likely to lead to an immediate face-to-face confrontation with an officer. However, the safest advice is not to fly with them at all. If you choose to take the risk, ensure they are in their original, discreet packaging and contain no more than 0.3 percent THC on a dry weight basis to comply with the 2018 Farm Bill regarding hemp-derived products. International travel with any cannabis product is strictly prohibited and can lead to imprisonment in many countries, regardless of where the item was packed.
