Justin Bieber gave SNL permission to write pot jokes.

Justin Bieberhas given Saturday Night Live writers permission to spoof him all they want when he hosts the show Feb 9 ... and that includes pot smoking

Sources connected with NBC tell TMZ ... Justin's camp has declared NOTHING off-limits. To the contrary, our sources say Justin himself has told producers to push him as far as they want.

Smart move ... It worked for aris Hilton, who appeared on SNL right after her sex tape was released. Alec Baldwin lso scored right after the whole Words with Friends thing.

FYI -- Justin's doing double duty on the show -- hosting and performing. Wonder how they're gonna stock the green room?


I hope Beliebers lose their shit tbh
