FILE - A TSA employee searches the luggage of a United Airlines passenger at a security checkpoint at San Francisco International Airport on Aug. 10, 2006. TSA officers are required to report any suspected violations of law, including possession of marijuana and cannabis infused products. While they don't search for marijuana or other illegal drugs, in the event they find an illegal substance, they will refer the matter to a police officer to enforce state law.
