According to an official report obtained by NBC News, there was so much marijuana smoke in Justin Bieber's Super Bowl-bound plane that pilots were forced to wear oxygen masks. The report also states that Bieber and his father were "extremely abusive" to a flight attendant.

The flight attendant, according to NBC's sources, spent most of the flight near the pilots because she was afraid of the Biebers and the other passengers. From NBC News:

"The captain of the flight stated that he warned the passengers, including Bieber, on several occasions to stop smoking marijuana," says the official report of the incident. "The captain also stated he needed to request that the passengers stop their harassing behavior toward the flight attendant and after several warnings asked the flight attendant to stay with him near the cockpit to avoid any further abuse."


"The flight attendant stated the passengers, including Bieber and his father, Jeremy Bieber," stated the report, "were extremely abusive verbally and she would not work another flight with them."

The pilots reportedly put on their oxygen masks to avoid inhaling the smoke; in addition to possibly intoxicating them, the pilots were concerned that the smoke might cause a positive drug test, which would have put their pilots licenses at risk.

According to the report, Bieber admitted to smoking marijuana in the plane, but told officials no drugs remained aboard. Officials from the Customs and Border Patrol and the Port Authority reported that the plane smelled strongly of marijuana but no drugs were found.

The flight crew refused to press charges, and Bieber and his crew were released after several hours of interrogation.
