Bieber Drug Test Shows Xanax, Pot

While the test results have not been formally released, law enforcement sources say that the toxicology report for Justin Bieber’s arrest in Miami Beach had him testing positive for marijuana and Xanax. The pop star pleaded not guilty to the DUI charges on Wednesday, as well as resisting arrest and driving with an expired license. An arraignment is set for February 14, but Bieber’s presence is not required.
