ecently, the Bay Area city of Belmont passed a law that targets people who smoke in their own homes. “I’m pretty sure I still live in America,” says smoker and Belmont resident David Scott. But if Scott lights up once the new law takes effect in January, he might just get a visit from a police officer. The mayor who championed the new law declares, “It is our responsibility to take care of everyone!’ and a pro-ban councilmember who worries about smoke wafting into neighboring units compares smoking in an apartment to shooting a gun through the wall. Smoking is one of the worst things you can do to your body, but how dangerous is second-hand smoke? Are banners saving lives or battering science? Are they progressive champions or plunderers of property rights?
