Rapper NAS first sampled marijuana when he was just nine years old.

The I Can hitmaker reveals his jazzman father Olu Dara would return from tours with tall tales and pot he'd share with his young son.

Nas says, "He'd be in the house smoking weed. He gave me weed when I was, like, nine years old. That was cool.

"(We'd) listen to music, talk, watch TV. I'd bug him for a hit, and on a few occasions he let me hit it."

And, despite what some may think about his early introduction to illegal drugs, Nas insists his dad was the perfect role model: "Other kids didn't have fathers like that. Either their father wasn't around or they were in jail - they weren't musicians who travelled the world and came back with stories."
