> Hopefully one day Cannabis will mostly supplant alcohol as the social drug of choice.

I hope not. I find the smell of Cannabis to be nauseating (almost like a swamp or distant sewage plant), and I wish people would consider that more often before smoking it in social settings. I realize that alcohol can smell as well, but it usually takes quite a lot of it for me to notice at least.

Another consideration: It's a lot easier for non-participating guests to abstain from alcohol than from Cannabis. Apart from peer pressure concerns, I can abstain or moderate my alcohol intake while still participating in social activities, regardless of the alcohol intake of my friends. When Cannabis is smoked in an enclosed hotbox though, I have to choose between intoxication and leaving.

I don't mind the brownies though.
