Brad Pitt has confessed he still knows how to get any drug he wants.

The 48-year-old father-of-six - who opened up about his former marijuana habit earlier this year - said he no longer uses drugs but is confident he would have no problem getting his hands on anything he wanted within 24 hours.

The 'Killing Them Softly' actor said: "My drugs days are long since passed but it's certainly true that I could probably land in any city in any state and get you whatever you wanted. I could find anything you were looking for. Give me 24 hours or so."

Brad was speaking to the audience at a Los Angeles screening for the new hard-hitting documentary he executive produced called 'The House I Live In' about the war on drugs on Friday (12.10.12), according to the Huffington Post.

He said: "We have spent a trillion dollars. It's lasted for over 40 years. A lot of people have lost their lives for it. And yet we still talk about it like it's this success."

Earlier this year, the 'Moneyball' star revealed he once used drugs as a way to escape the pressures of fame and this led to his battle with depression.

He said: "I got really sick of myself at the end of the 1990s: I was hiding out from the celebrity thing; I was smoking way too much dope; I was sitting on the couch and just turning into a doughnut; and I really got irritated with myself.

"I used to deal with depression, but I don't now, not this decade -- maybe last decade.

"I was doing the same thing every night and numbing myself to sleep -- the same routine: Couldn't wait to get home and hide out. But that feeling of unease was growing and one night I just said, 'This is a waste.'"
