Well, yeah, I live in an apartment building too and when I walk through the lobby I can smell tobacco if it's being smoked, pot too. But just because I can smell it doesn't necessarily lead me to the conclusion that there are enough smoke particles in my apartment over a long enough period of time to do me any harm. So just how much of a risk is second hand smoke in an apartment building? We should not be passing legistlation based on fear, IMO. Banning smoking in apartment buildings would be another step down the slippery slope we are already on to more government intervention in our private lives. I just think all options need to be explored before asking the government to take away more of our rights.
