Dude used cocaine and mdma (as he was an avid raver). I'm not condoning nor condemning the use of recreational drugs. I sometimes use those too in all honesty. The problem is, Zyzz was using juice during that time. So even if you did some blow the night before and made sure to do your cycle the next day, your heart had no time to recover. This guy most likely lived tachycardia and never paid it any attention. Worst thing was he goes into a Turkish bath type of thing and well, you know the rest. They don't put those warnings in saunas and steam rooms for no reason. It's not cool to die of a heart attack at such an early age. Aesthetic or not.
