This is an earlier photo of Redmond O’Neal, 26, the troubled son of actors Ryan O’Neal and the late Farrah Fawcett, who was arrested several years ago on drug related charges. It seems his drug problems are far from over even though he has promised publicly to stay clean.

People.com reports:

A year after graduating from an intensive, court-ordered drug program, Redmond O’Neal was arrested for investigation of drug possession Thursday by Santa Monica police during a traffic stop.

“After Mr. O’Neal admitted to being on felony probation and consented to a search, the officers found heroin and marijuana in the vehicle,” Sgt. Richard Lewis tells PEOPLE.

O’Neal said last year he planned to stay clean and sober after serving time for various drug-related arrests and then attending Los Angeles’s drug-court program.
