Pilots on the flight hired by Justin Bieber and his flunkies for the Super Bowl were so overcome with marijuana fumes they were forced to wear oxygen masks.

The official report in to Friday’s incident also revealed how the obnoxious teen and his father were “extremely abusive” to a flight attendant.

The verbal assault was so bad during the flight from Toronto to New Jersey she was forced to seek refuge near the cockpit.

According to reports in the U.S. the 19-year-old’s leased, Gulfstream jet had 12 passengers on board when it was detained by officials at Teterboro airport.

“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 behaviour 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 were extremely abusive verbally and she would not work another flight with them.”

Despite the luxury jet having a pressurised cabin the pilots choose to wear their oxygen masks to avoid inhaling marijuana and testing positive during any subsequent drug test.

A failure would have put the crew’s licence at risk.

According to sources, when the plane landed on Friday afternoon Drug Enforcement Agency, Customs, Border patrol agents and police boarded the jet.

They found there was still a strong smell of marijuana inside the cabin.

Two drug dogs then indicated the presence of the class B drug in three pieces of luggage, one of which belonged to Bieber, however no unsmoked cannabis was found.

The two other bags were listed as belonging to his personal assistant and his personal trainer.

However both “disavowed knowledge of the contents of the bags and stated they were actually Bieber’s bags, but they were forced to place their names on the bags,” according to the report.

No “contraband” was found but a second search found empty bags that appeared to have once contained pot.

None of the items could be linked to Bieber, his father, or their guests.

The “Boyfriend” singer was quickly separated from the other passengers as investigators carried out their searches.

The report stated “in past examinations, Bieber had become argumentative and abusive when together with his security team” which led to him being taken to a private area.

When interviewed the Canadian confessed to smoking marijuana and drinking alcohol, but stated he did not have any additional cannabis on him.

Bieber, his father Jeremy and 10 friends had flown in to the exclusive airport ahead of Sunday’s Super Bowl.

No members of the flight crew were willing to file charges against their passengers, so Bieber and his entourage were allowed to go on their way.

Bieber, who was recently charged while driving under the influence, resisting arrest, driving on an expired licence and assault, said he was due to watch the game between Seattle and Denver in a “private suite at the MetLife Stadium.

Following the game, which Seattle won 43 - 8, Bieber headed in to Manhattan to attend several post game parties.

However he was turned away by several clubs including the exclusive 1Oak.
