I see your point, but just want to draw a line between something you ingest willingly that affects only you, and something foisted semi-secretly on the entire public by a special interest (basically to make cars and/or fuel more marketable) despite their knowing, almost from the beginning, how toxic it was. (One of many great examples of humans using technology because they can, without giving due consideration to whether they should.) I would rather the law protected me from the actions of others, and let me be the one to worry about what I do to myself. [Edit: Which isn't to say there couldn't be a very persuasive weed marketing campaign or something, that influences people to use it and hides the negative effects. Just as there was a campaign to squelch public debate about the negative effects of tetraethyl lead. Nonetheless, being able to individually decide to reject inhaling lead, like you can with pot, would've been a welcome privilege.] Not sure what "current" generation means, by the way. I'm currently alive, and currently, I'm in the same generation I've always been in. (I'm not mad, just teasing you a bit.)
