*and science. Although, I give the gov't too much credit -- privately funded research (by tobacco companies) also clearly revealed the harmful effects of smoking, including secondhand smoke... in some cases before publicly funded research, IIRC.

Anyway you are correct, studies show that the various smoking bans are having dramatic effects on the incidences of smoking-related diseases. Seems to work better than telling impoverished kindergartners that they are free to leave their public school classroom anytime they want if their teacher starts smoking.
