In a recent interview with Playboy, JT was asked if he was still a pot smoker. 

"Absolutely," he answered. "Sometimes I have a brain that needs to be turned off. Some people are just better high." The singer/actor, now 30 years old, admits that during his episode of MTV's Punk'd, he was stoned off his ass.

As far as his plans for the rest of the year, it sounds like Justin has basically cleared his schedule to pursue every pothead's dream life. He says:

"There’s a lot to enjoy if I can just sit still, actually stop and take more time. That’s what I’m trying to do this year. I did four movies in a row and finished the fourth—the movie Now—on my birthday. Ever since, I’ve been retreating, doing nothing, listening to music, enjoying myself, playing golf."
