Looks like Justin Bieber wasn't just high on life when he was arrested last week for DUI. According to the singer's preliminary toxicology report, obtained and published by TMZ on Thursday, Jan. 30, the 19-year-old pop star tested positive for marijuana and prescription medication.

The report indicates that Bieber had both THC and Alprazolam in his system at the time of his bust. (THC is the principal psychoactive chemical in the cannabis plant, and Alprazolam is the key ingredient in depression/anxiety medication Xanax.) He tested negative for cocaine, opiates, meth, and other prescription drugs.

As previously reported, the "Heartbreaker" crooner was booked early Thursday, Jan. 23, for DUI, resisting arrest, and driving with an expired license in Miami Beach. He was released from jail later that day on $2,500 bail, and has since pleaded not guilty to the charges against him.

Unfortunately for Bieber, he now faces another charge in connection with a separate incident in Toronto. According to police there, he was involved in an altercation with a limo driver shortly before the new year.

"The Toronto Police Service requested that Justin Bieber appear in Toronto today to face an allegation of assault relating to an incident on December 29, 2013," Bieber's rep said in a statement to Us Weekly on Jan. 29. "We anticipate that this matter will be treated as a summary offense, the equivalent of a misdemeanor in the United States." 

"Our position is that Mr. Bieber is innocent," the statement continued. "As the matter is now before the Court, it would be inappropriate to address the specifics of either the allegation or of our defense at this time."
