Justin Bieber and his buddies drink the champagne of sizzurp ... and lots of it -- TMZ has learned.
Sources familiar with the situation tell TMZ ... Justin is a fan of Actavis prometh with codeine cough syrup -- known in the lean community as top of the line.
Street value runs around $800 a pint ... the biggest size you can get. It's not something you can buy over the counter at CVS for sure. You can either get it with a prescription or get it somewhere outside the U.S. We're told Bieber does the latter -- he has a connection that secures it in another country.
Our sources say when Justin is at his worst ... he downs between 8 and 12 ounces a day ... which is A LOT.
We broke the story ... Justin's people are urging him to go to rehab to tackle his drug problem ... but so far he's been resistant.
This is actually sad and serious and I can't at people rejoicing at this.... Celebrities obviously go through a lot and have immense pressure on them. It's not wonder Justin acts the way he does with his family life being a mess, his parents seemingly using him for money, and tons of people giving him hate every day. One of my friends worked backstage at a show that Justin was at and said that he had outbursts where he would start crying and his people said it was a normal thing. He needs help, not sick people rejoicing in his demise.
