Back when I was younger, I would usually breathe in second hand smoke from people who smoke almost everywhere in public. I would smell cigarette smoke while walking down a busy street, along the park or eating in a restaurant. A couple of years back, our local city government has implemented laws regarding prohibition of public smoking so now, the air feels much better to breathe whenever I go out on public. There are designated smoking zones in the city and anyone caught smoking in all the non-smoking zones are immediately warned by authorities. Is it also the same where you live? What are your thoughts on this?
