Cause of death unknown

"I was working on Lost Boys when I smoked my first joint. I did cocaine for about a year and a half, then it led to crack. I started on the downers which were a hell of a lot better than the uppers because I was a nervous wreck. But one led to two, two led to four, four led to eight, until at the end it was about 85 a day." Corey Haim
Hmmmm I wonder how he died?
