Justin Bieber's toxicology report from his DUI arrest has allegedly shown that he has tested positive for marijuana and prescription medicine.
The 19-year-old singer's urine was tested right after being hauled into a police station in Florida and the reports claim the presence of cannabis and Alprazolam, ingredient in anti-anxiety medication Xanax, in his system, TMZ.com reported.
The report also showed that the 'Baby' hitmaker tested negative for cocaine, opiates, meth and other drugs.
