Justin Bieber tested positive for marijuana and the anti-anxiety drug Xanax after his DUI arrest in Florida last week, but no traces of other illicit drugs were found, according to a preliminary toxicology report.

The 19-year-old pop star was arrested in Miami Beach on Jan. 23 after being pulled over for allegedly racing in a neighborhood. Bieber pleaded not guilty to charges of driving under the influence and with an expired license and resisting arrest. Police said he told authorities he had "consumed alcohol, smoked pot and prescription medication."

The preliminary toxicology report was released on Thursday, Jan. 30. Bieber was also tested for meth, cocaine, opiates, Oxycodone and other substances and no traces of them were found.

The legal drinking age in the United States is 21. A police report issued at the time showed breath tests placed Bieber's blood-alcohol content below the .02 level considered intoxicated for under-21 drivers, the Associated Press reported.

Detectable traces of tetrahydrocannabinol (THC), the psychoactive ingredient in marijuana, or cannabis, can remain in a person's body for up to three months if they are chronic users. Traces of one dose of Xanax can remain in a person's body for up to two days.

Pot is permitted in California, where Bieber maintains a home, if used for medicinal purposes. It is unclear if he has a prescription. In Florida, a vote to legalize marijuana for medicinal use has been scheduled for November following a Supreme Court ruling.

Assault charge in Canada

The news comes half a day after Bieber turned himself in to police in his native Canada and charged with assault stemming from an alleged December incident involving his and his entourage's limo driver in Toronto. His lawyer said the singer is innocent and that he expects the case to be treated on the same level as a misdemeanor.

Bieber is also being investigated for possible felony vandalism in California, where he maintains a home, following an alleged egging against his neighbor. The singer has not been charged with a crime and has not commented. Earlier this week, paparazzi photos of moving trucks at his house were posted online. He has not commented.

His legal turmoil and a slew of other incidents, such as one in which he urinated in a restaurant's mop bucket and sprayed cleaner fluid on a picture of former President Bill Clinton, spurred an online petition calling for the singer to be deported. It was posted on the White House website and has been signed more than the 100,000 times, which means the U.S. administration must respond to it.
