Beginning March 1, my company (a large industrial/aerospace firm) is banning all tobacco from company property. Cigarettes, cigars, pipes, chewing tobacco, everything. They have gone so far as to ban the possession of tobacco, not just using it.
Whether this becomes enforceable remains to be seen, but the point is that employers have decided that smokers cost them money in lost productivity and increased medical expenses. So employers are trying to make it harder to smoke in the hope that smokers will either quit smoking or quit the company.
The writing is on the wall. In case anyone has missed it, smoking has almost completely become socially unacceptable. Life as a smoker is likely to get a lot worse before it gets better (if ever). Consider that 20 years ago, there were virtually no restrictions on smoking anywhere and try to imagine what it will be like 20 years from now.
