Unruly Passenger Blames Medical Pot Cookies Calif. man had double dose before in-flight freak-out By Rob Quinn, Newser Staff Posted Feb 4, 2010 4:36 AM CST 20 comments Comments Cookies containing marijuana are shown for sale at the San Francisco Medical Cannabis Clinic in San Francisco. (AP Photo/Eric Risberg) (Newser) – A San Francisco man who screamed, dropped his pants and attacked crew members on a US Airways flight now says it was the pot cookies that made him do it. Kinman Chan, who holds a valid medical marijuana card, told FBI agents that he ate a double dose of marijuana cookies before boarding the Philadelphia to Los Angeles flight last weekend, AP reports. Chan's antics forced the flight to be diverted to Pittsburgh, where he is being held on charges of interfering with the duties of a flight attendant. Marijuana advocates say Chan's problems are probably bigger than a cookie. "Most anecdotal evidence shows marijuana makes you even more subdued," the California director of the Marijuana Policy Project tells SF Weekly. "I'm definitely dubious of this claim."
