Found a cool techno 'net radio station, and surfing around their forums a bit while I was bored I found this link...

Kinda makes ya think about some of the stuff you do and how dangerous it really is. As far as it relates to this discussion... weed has a 1 in 10-million chance of killing you, while alcohol falls into the 1 in 1000 category, and tobacco in the 1 in 100 category. Also interesting (from my point of view at least) - the most dangerous drug I've ever tried according to this chart falls into the 1 in 10000 category (not counting alcohol, which I don't believe causes 1 in 1000 to die unless you drive right after or some such) is far safer than say motorbike racing, which I'm leaving tomorrow morning to do for the weekend.
