The 48-year-old Phillips is out on $20,000 bail.
Phillips was heading to New York last month when she failed to pass a security screening and a secondary search turned up needles and suspected drugs.
She is the daughter of John Phillips, founder of The Mamas and the Papas pop group. She was fired from "One Day at a Time" in 1982 for drug-related reasons.
