Which is worse exposure to second hand cigarette smoke or exposure to auto exhaust?

Nothing to choose: Both are bad in different ways. Tobacco smoke predisposes to heart attacks, aggravates respiratory problems and may marginally increase the risk of cancers. Auto exhaust causes respiratory damage, carbon monoxide poisoning and depending on the type of exhaust may increase the risk of cancers.

A 50-year-old member asked:

Isn't breathing car exhaust as bad, or worse for a child than breathing second hand cigarette smoke?

Avoid both: Infants do not benefit from any toxic exposure, inhaled or otherwise. Gasoline fumes, carbon monoxide, perfume, plug ins, fragrent cleaning supplies and smoke all should be avoided.I don't know of any kid who is held as close to an exhaust pipe as many women do to their smoke tainted hair. There is no justification for smoking if a child is present in the home. Second hand smoke is a killer period !
