Yes, second hand smoke is listed as a class A carcinogen by the EPA, as well as the IARC, right along with Solar Radiation........will we be seeing sun-screen police soon?

But you are correct.......its really about rights......yours and mine and everyone elses'. You have as much right to choose a non-smoking establishment to patronize as I do to choose a smoking establishment......or at least I still have that right where I live, some of us don't any longer.
