For those not familiar with the drug called Sizzurp, they’re bound to be familiar with it now, since one of the biggest pop stars on the planet has allegedly been using it.

According to TMZ, the 19-year old has been drinking Sizzurp on a regular basis, which is a mixture of soda, codeine and promethazine. Some people toss a piece of hard candy in there too, like a Jolly Rancher.

This isn’t the first time Bieber has been linked to drug use, as he was caught smoking weed on a couple of different occasions, and as a result made fun of himself in a “Saturday Night Live” skit. And based on a TMZ source, the singer has also been popping Xanax, which might explain some of his recent erratic behavior.

Additionally, the celebrity gossip site revealed that Bieber doesn’t sip just any type of promethazine, he prefers an expensive brand called Actavis, which goes for about $800 a pint, and it’s also the most you can buy in one bottle. Allegedly, people on the inside of Bieber’s circle have been aware of his drug usage for quite some time, and they’ve been trying to get him into rehab.

Some would probably say the past year for the pop star has been somewhat peculiar, as he’s been acting much differently than he was in his younger and more squeaky clean days. And others might say the acting-out and the drug experimentation is normal for a teenager trying to figure out himself and determine what’s really right and wrong. But the alleged drug use could be a sign that Bieber is on a downward spiral towards a bad place, and if he doesn’t pull it together, he could lose everything that he’s worked for up until this point.

Whether the Sizzurp allegations are true or not remains to be seen, but the fact that Bieber has been hanging out with folks who use drugs and he’s been caught smoking funny looking cigarettes, it’s going to be hard to convince people that he’s totally sober. It’s safe to say that both time and Bieber’s future behavior will determine if he really has a drug problem or not.
