Murphy Lee was arrested on Halloween on charges of drug possession and driving under the influence of drugs.
The rapper and St. Lunatics member had been pulled over on October 31 near St. Louis for an expired license plate when police found marijuana in his Mercedes, according to The Associated Press.
Lee was arrested for possessing less than 35 grams of marijuana and driving under the influence of drugs after Sheriff's deputies allegedly smelled marijuana in his car. He is expected to appear in court next month.
An attorney for Lee, born Tohri Harper, told the AP that the rapper expects to plead not guilty.
