Jack Black's Bad Heroin Trip

(andPOP) - Jack Black has admitted to a one-time experience with heroin.

The "Kung Fu Panda" star told Blender magazine: “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.”

Black has recently opened up about his troubled childhood, when he used to sniff glue and steal money from his mother to buy cocaine before the age of 15.
