Justin is "absolutely" a pot smoker, he said in a 2011 interview with Playboy. "The only thing pot does for me is it gets me to stop thinking. Sometimes I have a brain that needs to be turned off. Some people are just better high," he said. That certainly wasn't the case when he first appeared on MTV's Punk'd. "I actually stopped smoking pot for nine to 10 months after that. I was so stoned. If you ask my friends, if they're honest, they would probably say that's the only way to get me as dizzy as I was."
