Why do you need to avoid being offered it? Surely you're able to say no if you don't want any. If they're the types who aren't going to like you if you don't do coke then you're not going to have a good time with them whatever you do and are better off finding a different party, but I'd have thought considering the price and moreishness of it they'd be happy to not have to give away their stash













There was a debate about this a while back too.
