Short answer
TSA does not search for drugs. Checkpoint screening looks for weapons, explosives, and items that threaten an aircraft. TSA officers do not file drug charges. If screening turns up drugs, TSA can call local police, and local police decide what happens next.

What the checkpoint is for
Screening at a US airport has one stated purpose: aviation security. Officers check IDs, X-ray carry-on bags, and screen passengers with body scanners or pat-downs. A bag search follows a trigger: an X-ray anomaly, an alarm, or a prohibited item in the image. Officers are not looking for a bag of cannabis or a loose pill bottle.

That does not make a checkpoint a shield. Screening gives officers lawful access to the contents of a bag. Items in view during that access are fair to act on.

What happens when TSA finds drugs
TSA's public position: officers do not search for marijuana or other illegal drugs, and a finding is reported to law enforcement. The referral goes to airport police or the local agency with jurisdiction. TSA does not arrest, seize for prosecution, or file charges on its own.
- Carry-on find: TSA calls airport or local police. Police choose a citation, an arrest, or no action.
- Checked bag find: a TSA baggage inspector opens the bag for a physical inspection. A drug in the bag triggers the same referral.
- No finding: the bag closes and the flight proceeds.
Federal law applies in the air
Airports and aircraft sit in federal jurisdiction. Marijuana is a Schedule I substance under the Controlled Substances Act, and federal law does not recognize state medical or adult-use programs. A passenger who buys cannabis in California under state law can still meet federal exposure at a California checkpoint.
State status matters to local police. It does not bind federal officers. Federal penalties for possession are set in 21 U.S.C. 844.
Cannabis specifics
TSA's cannabis guidance covers flower, edibles, oils, and CBD products with THC. TSA says officers do not search for these items and says a finding goes to law enforcement. In practice the result depends on the police agency at that airport and its local policy.
Points to keep straight
- TSA is not a drug enforcement agency. Its officers screen for threats to the plane.
- Screening still opens bags. Any item in view can be referred.
- Federal law covers the airport and the aircraft. State cannabis law does not change that.
- Airport police, not TSA, make the arrest decision.
Carry quantities and packaging policies differ by state and by airline. Check the rules for the airport and the carrier before a flight.
