Meh, lots of crap is dangerous, depending on a lot of factors. Marijuana is not, to me, as dangerous as going into a gun fight with only a knife, but it is more dangerous than, say, holding a de-clawed kitten.
I would not engage in it, that does not mean I don’t do things that could potentially be more dangerous (like cutting my vegetables toward me instead of away from me). So I guess what I’m saying is, just because something could be dangerous doesn’t necessarily mean you should strictly keep away from it in every instance. That does not, of course, apply to hardcore drugs, which everyone knows should be kept away from, as they’re highly addictive and more dangerous than a great many things.
