Justin Bieber pot smoke so thick, airplane pilots forced to wear oxygen masks: singer and dad Jeremy Bieber 'extremely abusive' to Canada flight crew [VIDEO]

Oh, Justin Bieber... what's next?

According to NBC, the singer's private jet was searched upon arrival at the Teterboro Airport on January 31 (before heading to the Super Bowl in NJ). And things weren't too pretty.

Apparently, airplane pilots were forced to wear oxygen masks in order to not get high - because there was SO much pot smoke in the air.

NBC obtained a police report claiming that clouds of smoke from the marijuana were "so thick," the flight crew had to put on their "emergency equipment" in order to land the plane safely.

Bieber was partying onboard with ten other friends (and his father).

Not only that, but the 19-year-old pop sensation and his dad Jeremy Bieber were supposedly not very nice during the trip. Isn't smoking weed supposed to clam you?

The father and son "tag team" allegedly got "extremely abusive verbally" to a female flight attendant. They refused to stop such "harassing behavior" - the unidentified female was forced to take "refuge" near the cockpit. The entire crew tried to stop such vulgar attitudes, but nothing helped.

Maybe Mr. Bieber isn't the best influence on his son...

Here's a portion of the police report:

"The captain of the flight stated that he warned the passengers, including Bieber, on several occasions to stop smoking marijuana...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 were extremely abusive verbally and she would not work another flight with them." 

After finally landing in New Jersey, the Biebs was again questioned by officials separately because "in past examinations, Bieber had become argumentative and abusive when together with his security team." The "Believe" crooner finally admitted to smoking marijuana and drinking alcohol, but he had no more weed in his possession.

Two drug dogs boarded the plane and allegedly alerted authorities to the presence of drugs in three pieces of luggage:

"One bag was labeled as belonging to Justin Bieber, one was listed as belonging to his personal assistant ... and one [was] labeled as belonging to his personal trainer," the report says. "[They] 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."

However, no members of the flight crew were willing to filed charges - wonder why?

What's up with Bieber's troublesome behavior - maybe it's time for a break?
