The toxicology report for Justin Bieber from his recent Miami arrest is out, reports TMZ and NBC 6 in Miami.
The pop star, 19, who was tested right after he was arrested for driving under the influence on Jan. 23, came up positive for THC and Alprazolam, says TMZ.

THC is in marijuana and Alprazolam is the key ingredient in Xanax (prescription anti-anxiety medication).

The report also shows Bieber tested negative for cocaine, opiates, meth and other drugs. It all jibes with what he told police when he was arrested.
