A San Francisco man claims he was high on a double dose of medical marijuana cookies when he screamed, dropped his pants and attacked crew members on a cross-country flight, forcing its diversion to Pittsburgh, the FBI said Wednesday. 
 
 Kinman Chan, 30, was charged in a criminal complaint with interfering with the duties of a flight attendant on allegations that he fought with crew members of US Airways Flight 1447 from Philadelphia to Los Angeles on Sunday. His federal public defender, Jay Finkelstein, declined to comment. 
 
 Crew members said Chan made odd gestures before he entered the plane's rear restroom shortly after takeoff and began to scream, according to the complaint. 
 
 Chan told the FBI that he "came back to reality" and exited the restroom, at which point the crew noticed his "pants were down, his shirt was untucked and all the compartments in the restroom were opened." 
 
 When crew members tried to get Chan to sit, he fought them and had to be subdued in a choke hold, the complaint said. 
 
 Chan told agents who interviewed him in Pittsburgh that he ate marijuana cookies while waiting for his flight to depart in Philadelphia. 
 
 Margaret Philbin, a spokeswoman for the U.S. attorney's office in Pittsburgh, said Chan has a legally issued medical marijuana card for a "legitimate" health issue, which she declined to identify. 
 
 Chan was arrested in Pittsburgh, then jailed until a federal magistrate granted him bond Tuesday, Philbin said. 
 
 Chan remained jailed Wednesday because Allegheny County officials have also charged him with disorderly conduct, Philbin said. 
 
 The charge of interfering with the duties of a flight attendant carries up to 20 years in prison and a $250,000 fine.

 There's a reason Reefer Madness has become a laugh riot among bong-toting college students across the realm. After all, you don't have to be stoned into the next dimension to get a laugh out of earnest depictions of marijuana turning people into crazed, violent killers and rapists. And boom microphones dropping into the shot are funny, too.Well, enter Kinman Chan. The 30-year-old San Francisco man is using the "Pot Made Me Do It" defense regarding a midair outburst in which he fought with US Air personnel and forced his Philadelphia-to-Los Angeles flight to land in Pittsburgh . According to flight crew members, Chan ransacked an airplane bathroom while screaming, then emerged from the commode with pants down and shirt untucked. After refusing to take a seat, he grappled with flight attendants. He now claims he popped twice his normal dosage of medical marijuana cookies ― which apparently explains it all.Well, not for Aaron Smith. The California director of the Marijuana Policy Project said Chan may have some problems ― but too much pot isn't one of them. "Most anecdotal evidence shows marijuana makes you even more subdued. [Violence] is something alcohol is linked to when you hear about problems on airplanes," he said. "I'm definitely dubious of this claim."While a spokeswoman for the U.S. attorney's office in Pittsburgh ― where Chan is being held in custody ― noted that he had a medical marijuana card for a "legitimate" health issue, Smith doesn't think this instance will cast aspersions on other medical pot users."I think everybody knows that marijuana doesn't cause this sort of behavior," he said. "I don't think this guy's claims are going to have much affect beyond this little story."Regarding Chan's medical marijuana cookies, a chuckling Smith adds, "Maybe it was the sugar."
– 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."
