Justin Bieber 'abusing drugs regularly'

Justin Bieber is being urged by his people to go to rehab since he is using drugs with alarming regularity, it has been revealed.

According to a source, the 'Baby' hitmaker has been using sizzurp regularly, which is typically codeine and promethazine mixed with Sprite and a Jolly Rancher, TMZ.com reported.

Bieber and his crew refer to it as "lean", and it's a very dangerous narcotic that can trigger seizures.
