I also yearn for smoke-free places. Since January they made train stations and trains non-smoking. Some people still flout the rule, but it's not too bad in the stations. However, on the platforms...there are smoking areas at the end of the platforms, but most smokers seem to believe because they are 'outside' (in a small, enclosed area) their smoke won't bother anyone. Officials are not especially good about enforcing the rule either. Also when I walk in to the station I have to walk through people clustered by the door to smoke.
So I still have to take a shower every night if I've gone to work, to get rid of the allergins. If I want to go out to eat, I have to take an allergy pill. And of course I still carry my inhaler.
I think perhaps these people don't realise that their smoke carries because they are no longer capable of smelling it. I, on the other hand, could probably be used as a drug-sniffing dog if they ever make smoking illegal. At work I have to repeatedly remind people that if they smoke by the (open) basement door the smoke is pulled in to the building, and I really can smell it on the second floor.
I really don't have a problem with people taking whatever drugs they like, provided others aren't forced to take them in the process. I don't understand how so many pill-form drugs can be illegal in many countries, while something that affects everyone around can be considered socially acceptable and legal.
