Jack Black was a cocaine addict during his teens

“I remember just lots of turmoil from that time period. I was having a lot of troubles with cocaine… I was hanging out with some pretty rough characters. I was scared to go to school (because) one of them wanted to kill me. I wanted to get out of there,” Jack said.

The “School of Rock” star felt he had no one to turn up to in the family and decided to confess everything to the school therapist.

“I spilled my guts, telling him I felt guilty about stealing from my mom to get money for cocaine. I cried like a baby. It was a huge release and a huge relief. I left feeling euphoric, like an enormous weight had been lifted from me. It changed me,” he recalled.
