The Los Angeles County District Attorney's office said Redmond O'Neal is scheduled to be arraigned later Tuesday.
Authorities suspect the 24-year-old was carrying heroin when he was arrested Sunday at a jail in Castaic while giving a ride to a friend. O'Neal remains in custody.
His attorney did not immediately return a phone message Tuesday morning.
It is the most recent in a string of drug-related arrests for O'Neal, who remains in custody.
Prosecutors amended their complaint Tuesday morning to note that O'Neal was already on bail for a drug arrest last year in a case involving his father. Prosecutors also raised their bail recommendation to $75,000.
Redmond O'Neal and his father were arrested last year at the actor's Malibu home after deputies said they found methamphetamine and drug paraphernalia during a search. Redmond O'Neal was on probation for a previous drug conviction and has pleaded not guilty in that case.
Ryan O'Neal pleaded guilty in the case and was ordered into an 18-month drug diversion program. He was nominated for a best actor Academy Award for 1970's "Love Story."
