There is legislation in almost every state to prohibit smoking in cars with children under 18. The anti’s just can’t stop themselves from stamping out tobacco everywhere. They will find a way to get into your home, if you have children, it is only a matter of time.
In the 70’s there was a major movement, through the schools, to report parents who smoked marijuana at home. Children did report their parents because they had no idea of the consequences. Many children were removed from their home and placed in foster care.
It is a safe assumption that this will be a new avenue for the anti-movement.
