According to the report by TMZ, Bieber's urine was tested following his arrest and when he was caught driving under the influence on January 23. The test revealed that there was THC and Alprazolam in his body at the time of the incident.

The toxicology report also demonstrated the 19-year-old singer did not test positive for meth cocaine, opiates, and other drugs.

In the early hours of last Thursday, he was detained in Miami Beach after a police officer pulled him over on suspicion of racing a hired yellow Lamborghini on a public street.

The singer was also indicted with resisting arrest and driving on an expired license. The young star was later freed on bail of $2,500.

According to TMZ, the toxicology report matched with the police department's report when officers said Bieber told them his mother Patricia "Pattie" Mallette had given him with prescription pills.

As for the marijuana found in his system, Bieber also said to the police he had been smoking marijuana in his recording studio throughout the night, according to TMZ.
