On Tuesday, former talk show host Montel Williams was stopped by the Transportation Security Administration also known as TSA at the airport in Milwaukee, according to the Milwaukee County Sheriff’s Office.

Police stopped Williams as he went through security for possessing a metal pipe commonly used to smoke marijuana. The pipe reportedly set off the metal detector, alerting the TSA to its presence. Williams has multiple sclerosis and allegedly uses pot to manage his pain from the disease.

Reports say that Montel Williams was cooperative and was released after paying a $484 fine. Williams aged 54, has been a medical marijuana advocate since being stopped at a Detroit airport last year for possessing drug paraphernalia.
