Eric Roberts moved into Dr. Drew Pinsky’s Pasadena Recovery Center last week for a crippling addiction to prescription marijuana, his wife has revealed.

The actor has been off hard drugs and alcohol for 15 years, Eliza Roberts tells E! News. “He has no interest in anything, other than marijuana.”

Roberts has anxiety issues, so he turned to doctor-prescribed weed for relief after traditional medication did not agree with his body. He had no such issue with the marijuana. “However, a dependency is a dependency and he doesn’t want to be dependent on it anymore.”

A rep for the actor has already tried to downplay Eliza Roberts’ revelation, saying the actor is seeking help “not for any serious drug/substance, or prescription drug abuse problem.
