> The second hand smoke you’d encounter on a sidewalk is completely harmless. Any affect, if any, to your health would be completely insignificant and unmeasurable. This sounds correct to me but keep in mind marketing the dangers of second hand smoke was an effective way to get people who thought of it as a solitary activity to thing of the secondary impacts. Most smokers don’t care about their long term health enough, but they may care about the health of those around them.
