Plane forced to make emergency landing after passenger lights up

An unruly pot-smoking passenger forced an American Airlines plane into an emergency landing Friday night when he tried to light a doobie in the cabin.

The flight from Arizona to Minnesota was diverted to Colorado at around 6:30 p.m. when the man began to behave aggressively and punched another passenger, TMZ reported.

Denver cops detained the passenger, but determined he was suffering medical issues and did not press charges.
