1) They have now absolutely proven that second-hand smoke is harmfull, not only long term, but short term, causing pulmonary and cardiac cells to function at a lower level while exposed.
2) It\'s fine to say that owners have a right to run any kind of establishment, but then they\'re discriminating not only against non-smokers, but against the waitresses and bartenders who would NOT be able to find jobs away from smoky bars.
3) They\'re not taking away your right to smoke (yet... that\'s probably decades away), but they\'re saying that your right to smoke interferes with MANY other peoples right not to, and so you\'ll have to take it outside.... where the others won\'t be affected.
Remeber... every rule and law in civilized society is based on one principal, and if everyone followed it, we would all be a lot better off.
You have the right to do almost anything you want, but your rights end where another individual\'s (or society\'s) rights begin.
*edit*
PS - Since Ottawa went smoke-free last year, the night life here has improved 100%, at first, there was a drop in night-goers, but now it\'s as busy as before (smoker\'s simply going outside), and I don\'t have to quarantine and dry-clean my shirt, pants, and jacket every time I go out. I for one love the improvement.
