Second hand smoke impacts the health of people who aren’t smoking but are inhaling the smoke due to their proximity to one who is. In an attempt to prevent injury from second-hand smoke, many states in the US have already banned smoking in restaurants, bars and other public areas. Recently though, several cities have started limiting it even further, placing restrictions on smoking in outdoor public areas such as parks and patios of restaurants and bars. Furthermore, in California, beginning in 2009 statewide, smoking in the presence of a minor 18 years or younger while driving will be a misdemeanor offense (referenced: Wikipedia).
