It is; the two molecules apparently form another molecule as part of your enzymatic processing of them I think -- instead of cocaine and alcohol, you end up with cocaethylene. It's interesting to note though that I've seen documentaries that stated some researchers say up to 75% of cocaine users always drink at least some alcohol while using. Apparently it lengthens the effect of the coke.I find this bizarre, personally, because alcohol kills the amphetamines that I so enjoy and I don't touch it unless I'm not taking speed. But it is interesting if true.
