Child molesters are like hunters going after prey.
Teaching a child to say no to drugs, or anything else, begins in earliest childhood, when a parent respects the child's boundaries, listens to their feelings and allows them to exercise their right to say no. Obedience teaches just the opposite, that the child's no does not count. Guess what-some kids wanted me to smoke pot with them. When I told them I didn't want to, they said I was a sissy. I told them they were dumb.
