Prior to Justin Bieber‘s jet being held at an airport in New Jersey on Friday on suspicion that it was carrying marijuana, the pilots and flight attendants were forced to deal with the pint-sized pop brat on what’s been dubbed the “pot plane.”

According to an official report, the troubled teen singer and his entourage smoked so much marijuana on the flight between Canada and New Jersey that the pilots were forced to wear oxygen masks.

They wore the masks, so they wouldn’t risk inhaling marijuana and failing any subsequent drug test, which would put their licenses at risk.

“The captain of the flight stated that he warned the passengers, including Bieber, on several occasions to stop smoking marijuana,” the official report of the incident, obtained by NBC News, said.

In addition, Bieber, 19, his father Jeremy, 38 have been accused of abusing a flight attendant on a private jet until she was forced to hide in the cockpit -- refusing to work for him again.
