This combination really worries me, because the only times I've been to parties and events with coke, there was always a lot of drinking going on too. I always read that it is such a dangerous combination and to practice harm reduction you should only do one of these at a time. But I can't even imagine a situation where someone is doing coke and not drinking too? It just doesn't seem to be the way things work out in reality. What do you think? It scares me a bit but this must be one of the most common party combinations out there. Are there really people that separate drinking and drugging?
