Bieber revealed that he first tried marijuana when he was just 13 after rocketing to fame as a child when he was discovered on YouTube.

After becoming dependent on weed, Justin began to drink lean — a narcotic substance often called purple drank or sizzurp — as well as taking pills, doing Molly, and trying mushrooms.

I got off the pills but never went to the root of everything so I just circled back around which most people do.'
