Dizzee Rascal doesn't smoke "straight" cigarettes.
The British rapper has revealed he doesn't "see the point" in smoking unless the cigarette contains illegal substances.
He said: "I've never been just a straight cigarette smoker. I didn't see the point - I always thought if I was going to smoke, I was going to get high."
But the 'Dance Wiv Me' hitmaker insists he has rarely been tempted to experiment with drugs.
He said: "To be fair, I haven't had that much experience. Every now and then, if I'm around certain people, they're smoking weed and I want to get the vibe, I do it. But I've never spent my last tenner on a bag of weed. I've popped a couple of pills, but I've never done cocaine, I've never done heroin."
However, the 24-year-old star does have some habits which cause him problems. He added: "Sex is really important to me. It gets me into trouble, actually. It's a bit too important!"
