> Or are you referring to punishing the parents? Generally these kinds of laws go after adults who sell, or otherwise enable access, to drugs, or pornography, or violent films, etc., to children. In my jurisdiction, it's a crime for a store to sell cigarettes to children under 19. And failure of parents to take basic steps to prevent their younger kids (up to 14) from getting their hands on them, is considered child abuse/neglect, much like if you allowed a toddler to drink poison.
