Brad Pitt laughs: 'I'm a drug addict' at movie screening Alberto Pizzoli / AFP - Getty Images Brad Pitt still hasn't said very much about his wedding plans with Angelina Jolie. One subject he opened up about a bit more on Friday? Drugs. "I'm Brad Pitt and I'm a drug addict," the "Killing Them Softly" star, 48, joked, laughing, at Friday's "The House We Live In" screening in Los Angeles, where he introduced filmmaker Eugene Jarecki, whose new documentary investigates the drug epidemic in the U.S. PHOTOS: Celebrity pot smokers "No, my drug days have long since passed," clarified the engaged father of six. Pitt (who announced his engagement to Jolie, 37, this past spring) has been frank about his marijuana use in the past. In a controversial Parade interview from September 2011, Pitt said the earlier phase of his superstardom (including his marriage to Jennifer Aniston) left him depressed -- and smoking pot. I started to get sick of myself sitting on a couch, holding a joint, hiding out. Pitt told Parade.

I could find anything you're looking for, give me 24 hours or so. And yet we still support this, I have to say, this charade called the drug war. The actor-humanitarian continued of the "drug war": "We've spent a trillion dollars, it's lasted, it's gone on, for over 40 years -- a lot of people have lost their lives for it. And we still talk about it like it's a success. And yet it's a flawed, a backwards system/strategy that actually perpetuates itself.
