When asked about relapsing, the 55-year-old said “I don’t have a problem at all with smoking. I think it’s great. I think it’s a great drug.” Harrelson continues “The effect of it 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.”
