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.
