Tyler, The Creator: No drugs in the studio

Rapper Tyler, The Creator refuses to allow marijuana or booze in the recording studio when he's working on new music because he demands everyone has a "clear mind," a lesson learned by one of A$AP Rocky's entourage members over the summer, when the two rappers got together to create their song 'Potato Salad'.

After noticing the guy light up a joint, Tyler recalled to Fantastic Man magazine, "I went in the room and took the blunt out of somebody's hand, threw it on the ground and stepped on it and said, 'This is a distraction. This needs to stop. We are here to f##king work. Not to hang out.' F##k that. Clear mind. At least once, godd##n. We're drug-free at night."

The 27-year-old went on to explain why he has no desire to drink to excess, insisting it's never appealed to him.

"I just don't want to drink," he said. "I know that I don't want to be that drunk guy. But I do know I want to hit a jump on a dirt-bike. I can look at that and say: 'I want to do that.' I've never seen anyone drunk, like, 'Damn, I want to be that.' So, I guess I just naturally got it pushed into my head that I have no reason to go over there and get f##king drunk."
