I used to be of the opinion, in a vague haven't-really-considered-it sort of way, that smoking was rude to other people but should be allowed anyway, because it wasn't any of the state's business whether people were rude.

Then I developed a close friendship with a person with asthma. She cannot go anywhere where there might possibly be people smoking, because she might die. Now I think smoking shouldn't be allowed anywhere, out- or in-doors.

However, I also think the tobacco companies should get busy developing a strain of Nicotiana that can be consumed some other way. A tisane, perhaps. Something that allows people to continue to get their fix without threatening anyone else's life.
