I disagree; I favor the legality of alcohol and tobacco, but I don't favor their use.
Has no affect on my comment at all.
Then did you mean that others may infer your favoring use if you favor legalization? Sadly, that's all too true ... even by "others" who should (and very possibly do) know better.
Yes, that is what I meant. There are millions of teetotalers and non drug users right now. But for something to be illegal and then to legalize it, to some that means, "OK, it used to be bad but now it is OK." Not good logic but true psychology.
