Justin Bieber, dad chose to overlook pilot's warning to put pot away

Justin Bieber and his father Jeremy Bieber reportedly refused to listen to the pilot when he repeatedly asked them to stop smoking pot during a flight from Canada to New Jersey.

A law enforcement source told CNN that marijuana smoke was so strong in the jet's cabin that flight crew members put on oxygen masks because they were concerned they might inhale so much it would cause them to test positive for drug use.

The source added that the 'Baby' hit maker and his dad were verbally abusive to the flight crew.
