If someone asks me I'll answer fully and honestly. I don't like all recreational drug use, think it's a waste of time and potentially dangerous to yourself and others. Then I'll share a bunch of statistics about how alcohol is responsible for 3.5% of all cancer deaths. And how even small levels of consumption increase the risk.

I'm not going to stop anyone from doing this, but if they're asking my opinion already then I'll let them know I think it's a bad idea.
