Justin Bieber smoking drugs on leased GIV.
I've just been reading about Justin Bieber and his entourage smoking so much pot on a flight into Teterboro that the pilots had to wear oxygen masks to prevent them from inhaling the smoke. The FA had to stay in the cockpit because the abuse from the passengers became too much to handle. Surely all this, especially the pot smoking, is enough to justify an immediate diversion. Apparently the captain asked them several times to stop smoking the drugs without result. I know I would not have continued the flight under those circumstances.
