Former day-time talk show host Montel Williams was cited for possession of drug paraphernalia as he attempted to board a flight at Mitchell International Airport in Milwaukee.

Williams was caught with a smoking pipe by Transportation Security Administration agents while walking through a security checkpoint. However, when the pipe was tested by TSA agents, it did not test positive for marijuana residue.

“There were four police officers involved in this entire situation,” Williams told The Milwaukee Journal Sentinel. “It’s very interesting that a wooden pipe that tested negatively took away the actions of four security officers that were there to protect and serve the country against the potential of terrorist attacks, bombs and other things.”

Williams paid $484 for the citation, forfeited the pipe, and was freed to continue his travel plans for the rest of the day, according to the Journal Sentinel.

Williams, who suffers from multiple sclerosis and founded the Montel Williams MS Foundation, has admitted using marijuana to ease the effects of the disease. He told reporters he was in Wisconsin to undergo a special treatment at the University of Wisconsin medical school.

According to the Journal Sentinel, Williams’ treatment involved stimulating the tongue with electrical impulses which flow into the brain to allow a smoother processing of information in patients with MS and other nervous system ailments. Williams has been undergoing the treatment since September.
