Justin Bieber's new documentary, Justin Bieber: Season is out, and the "Yummy" spoke rather candidly in the film about his prior drug use.

In the doc, Bieber admits to smoking his first blunt at 12 or 13 years old, before eventually becoming addicted to popping pills.

"It was just an escape for me," Bieber said. "I was young, like everybody in the industry, or in the world, who experiment. But my experience was in front of cameras and I had a different level of exposure. I had a lot of money and a lot of things, so then you have all these people around me hanging on and wanting stuff from me, knowing I was living this lifestyle that they also wanted to live."

The pop singer regularly made headlines for his bad boy behavior, but Bieber eventually got to a point where he knew that he had to stop:

"I decided to stop because... I was like, dying," he said. "My security were coming into the room at night to check my pulse. People don't know how serious it got. It was legit crazy-scary."
