Bieber's Miami toxicology reports reveals weed, pills use

Justin Bieber

It comes as no surprise, but the toxicology report is just in from Justin Bieber’s DUI/drag racing arrest in Miami Beach — and yes, it proved positive.

The teen superstar’s urine was tested right after he was arrested on a charge of driving under the influence on Jan. 23.

According to the report, first scooped by TMZ, Bieber’s urine indicated the presence of Alprazolam (key ingredient in the Xanax anti-anxiety prescription medication) — as well as marijuana use.

(Of course, Bieber himself had told the arresting police officers that he had been smoking pot in his recording studio for much of the evening.)

The good news — so to speak — was that the singer tested negative for cocaine, opiates, meth and other drugs.
