Heroin, coke, and alcohol. Quickest way to overdose, even if it is fun... RIP mate, we'll miss you.<p>My worst OD was with that mixture as well, only I was lucky enough to have people with me and live in a country where calling the emergency services doesn't end with police at your door for overdoses. Narcan in the back of the ambulance brought me back. I got clean a month later, and am still clean 20 months later.<p>Some of my friends weren't so lucky, and neither was Jack, the poor bastard. He did awesome work. Mudge had an awesome talk at Defcon where he told a story about Jack in Dubai, go have a listen, it's well worth it.<p>Drug abuse (opiates in particular) is more common in our field than we think, I believe.
