As I've pointed out each time someone brings up the subject, the health risks are no longer part of the discussion. The general public is simply tired of leaving bars and such smelling of stale smoke, cigarette, pipe or cigar. Add, that to the fact that smoking is a purely selfish decision ... Well, there you have it.
Smoking is being pushed back to it's roots, private clubs or one's home/farm. Of course one wuld need to own one's own home. Banks will soon, I'm convinced, refuse home loans to smokers when finally permitted to. Landlords are now selective with respect to smokers. They simply don't need the expense of changing out draperies, repainting and new carpet in their property each time a smoker moves out. Employers, since unions started demanding health insurance, wish to improve their bottom line by banning or, at the least, reduce the number of smokers employed. Health insurers can readily show the stats which show smokers as a body are risk takers and have worse attendance records than nonsmoking employees.
Smoking is a purely selfish choice which impacts others in ways they do not like. Just accept that we are engaging in a purely selfish act which is no longer tolerated by society in general. So, move indoors, buy a bigger plot of land and accept the fact that we, as smokers are not to be tolerated for a number of very valid reasons. I defy any of us here to put up an argument that supports smoking other than, "I like/enjoy it."
I suspect doctors are out there who, for a fee, would write a prescription for smoking as necessary for a patient to ... well, something, relax? I doubt it would withstand a challenge though.
