The simple answer is dont fuckin try. Seriously, this type of peer pressure gives us smokers a shitty rep. I usually ask "do you toke? do you want to? well tell me if you ever do" and leave it at that. That's one less person mooching off my stash, and they're getting the bad end of the deal, cause weed kicks ass.

If someone wants to try it for their first time, I'm glad to help (and I have a few times), otherwise, its their problem, not mine. Just don't peer pressure, you'll just sound like a douchebag.
