50 Cent insists he's one of the cleanest rappers because he has never even tried marijuana -- despite once being a drug dealer.
The rap star decided as a teenager he would never touch drugs because he saw what they did to his friends and clients.
He tells Spin magazine, "I got arrested ... when I was just a teenager. It was my second time being arrested as a juvenile, so the authorities thought it would be better to send me to a drug treatment program and see how drugs actually affected people.
"I stayed away from it, because I'd been hustling since I was 12 ... I was addicted to the lifestyle. I was always surrounded by people with drug addictions. I was in a household where everyone was drunk and crazy."
But 50 admits he has often had second-hand highs because his entourage is always smoking pot.
He adds, "Everybody I know always smoked pot, but I never had an urge to try."
And the rapper, who doesn't even drink alcohol, insists his recorded boasts about drug taking aren't for real: "That's me knowing there are 500,000 people out there who just want to play my records and get high."
