The attorney for Ryan O’Neal says the actor “found it extremely frustrating and upsetting” that he and 23-year-old son Redmond were charged yesterday with felony possession of methamphetamine following a Sept. 17 bust in Malibu, Calif. “He's not a drug user and he doesn't want to be thought of as a drug user,” the lawyer tells People of O’Neal, 67.
