Who is most at risk for secondhand smoke?

Anyone who is in the environment of a burning cigar, pipe or cigarette where that smoke expands to fill the space in a car or room, and anyone exposed to that breathing space is at risk. Second-hand smoke is not safe no matter what quantity you breathe it in. For some people it's even more dangerous. That would include people who live with smokers, roommates, spouses, the children, co-workers, anyone exposed to the sensation. If you can smell cigarette smoke, you're at risk for having some of the toxic effects occurring in you. The smaller you're packaged, meaning children or pets, the higher the individual risk is for them for the toxic effect.
