Jack Black has confessed that he experimented with heroin but was so terrified by the experience that he never touched it again.

Jack Black confesses that he experimented with heroin

He told Blender: "It didn't agree with me. I couldn't really feel my legs, and my heart felt like it was slowing down too much. I thought, 'Oh my God, it's going to shut me down. I'm going to die.'

"I went down to the 7-Eleven at the bottom of the hill, and I had this strange sensation that my legs were pumping, but the feet were just sort of lifeless stumps.

"I did a little shopping and then walked back up the hill and survived. And never did it again."
