No. TSA does not search for marijuana. Transportation Security Administration officers screen passengers for weapons and explosives that threaten aviation security, and the agency states it is not a drug enforcement agency. Screeners will not open a bag just to hunt for cannabis, but they can still find it during routine screening.

What does TSA actually search for?
TSA's mission is aviation security, not drug enforcement. Officers look for guns, explosives, and other items on the federal prohibited items list. Drug detection falls to other agencies, such as airport police or U.S. Customs and Border Protection.
Does TSA search your bag for weed?
A bag gets opened when the X-ray image shows something that looks prohibited, or when the bag itself triggers an alarm. If cannabis turns up during that search, the discovery is incidental rather than the reason for it.
Can You Fly with CBD Oil? TSA Regulations Guide
Odor alone is rarely the trigger for a checkpoint bag pull. How a TSA officer or local police respond can still vary by airport and state.
What happens if TSA finds weed in your luggage?
TSA does not arrest you or write you a citation. The officer alerts airport law enforcement, who then apply state and local rules. In a legal-cannabis state that may lead nowhere, while in other jurisdictions you could face a citation or an arrest.
Does TSA confiscate marijuana?
TSA has no authority to seize cannabis as a drug forfeiture or to charge you. The agency can turn the item over to law enforcement, who handle it under their own policies. Because a screener's judgment is involved, outcomes are not uniform from airport to airport.
Can TSA call police about cannabis?
Yes. TSA's published policy says officers who discover marijuana may refer the matter to law enforcement. That referral, not the search itself, is where the real risk sits.
Can you fly with legal cannabis between two legal states?
State legalization does not change federal law. Air travel moves through federally regulated airspace, so cannabis stays a Schedule I controlled substance for the duration of the trip. TSA applies the same referral policy no matter where your flight lands.
What about international flights and customs?
When you arrive from another country, Customs and Border Protection enforces federal law at the border. CBP can seize cannabis, issue fines, or deny entry, and non-citizens may face immigration consequences. Never pack cannabis on an international itinerary.
Do airports use drug dogs to find marijuana?
Drug dogs at airports normally belong to local police or federal agencies, not TSA. Their work is often aimed at larger trafficking cases rather than personal amounts. Even so, a dog alert can justify a police search of your bag.
Does a medical card protect you?
No. A state medical cannabis card or dispensary receipt carries no weight against federal rules at a federally regulated checkpoint. It may help you explain the situation to local police in a legal state, but it is not a guarantee.
Will TSA punish me for edibles or vape cartridges?
Edibles, cartridges, and flower are handled the same way. TSA does not target them, but if they appear on the screen or in a bag search, the referral process is identical. Packaging that resembles ordinary food does not change the policy.
Can TSA tell THC products apart from CBD?
No. Screeners cannot test potency or read a lab report, and legal hemp items can raise questions because they look like cannabis. Keep hemp products in their original labeled packaging to reduce confusion.
Is it a crime to bring weed to an airport?
That depends on state and local law, not on TSA policy. Check the rules of the airport's jurisdiction before you pack, and when in doubt, leave it at home.
