Steve O, a comedian/stuntman from the 2000s MTV show Jackass, claims that he snorted cocaine mixed with HIV infected blood - for a thrill.

The comedian, whose real name is Stephen Glover, talked openly about his substance abuse in an interview on In Depth With Graham Besinger, where he discussed the incident.

"I had this drug dealer, he lived very close by. Sometimes I would show up and the door would be unlocked but he would be passed out, 'cause he was very much a drug user as well as a dealer," Steve-O explained.

The 44-year-old told the interviewer that on one occasion, he was unable to wake his dealer, but noticed some cocaine residue on a table in the house.

"I went over to this table to scrape up a pile of cocaine to snort it, but as I had sat down looking at it, blood had been squirted, you could see, like, the little tiny little blood splattered on the residue." 

"This is how desperate and pathetic my addiction was, that I sat there, like, knowingly scraping up this tainted, like, blood cocaine and uh, I sat there and snorted it," he said.

"Which is so f**ked up - I snorted the blood of an intravenous drug user."
