As the actor tells Vulture, "I actually stopped smoking pot almost a year ago."
The subject came up during an interview for his new movie "Wilson," when he was asked what misconceptions people have about him. "They think I'm a party animal, which ... I am a party animal. I mean, that might be one thing. But I am a party animal. But on the other hand, I haven't ... I'm now extremely moderate."
He says he gave up pot because he had spent "30 solid years of just partying too f**king hard."
However, he's still a fan. "I think it's great. I think it's a great drug ... Even cops say that the side effect is euphoria... But when you're doing it all the time, it just becomes ... Well, you know. I feel like it was keeping me from being emotionally available."
Harrelson admits he still drinks: "But I try to be moderate with the drinking, too."
He added, "I really don't want this interview to turn into a whole thing about [quitting pot]." Sorry, Woody, that's the big takeaway here.
