Should smoking in cars/in homes that have children in them be illegal? (question is specific to USA).

I have a good friend who smokes CONSTANTLY and does so around her kids (in her home and in the car with the windows up which is even more disgusting). 
Clearly I'm a non smoker but I really don't care what adults do to their bodies but when children are concerned, I think it's selfish. The children can't speak for themselves that their lungs are filled with disgusting second hand smoke not to mention the numerous toxic chemicals (they always smell like cigarettes too which many other people have noticed). There are more strict policies in place like this in other countries but I think that we need this to be illegal in America.
