United pilot refuses to fly after passenger smokes pot on plane: 'Not willing to risk it'

He didn’t want to be flying high.

A United Airlines pilot refused to fly from San Francisco to Cancun, Mexico on Tuesday after a passenger smoked pot on the plane, resulting in a nearly four-hour delay.

In a viral Reddit post , a passenger who was aboard flight UA1679 recalled how the ill-fated trip was initially “delayed due to technical issues” then again after “someone smoked weed in the front bathrooms.”

“They got removed from the flight then sat on the plane for 40ish minutes waiting for crew to figure out what to do,” they explained. “Crew was concerned they got exposed, so we deplaned and are awaiting new crew.”

“The likelihood of testing positive from secondhand marijuana smoke in a well-ventilated aircraft is laughably low,” wrote A View From The Wing contributor Gary Leff.
