A child that is grown in a ghetto where everybody smokes and drinks.
Where gambling is seen as a normal thing. Where all manner of hard drugs are taken. That very child will grow up and continue taking all those hard drugs believing that it is a real way of life.
Before he would understand that he is not in the right lane. It would be late for him and by then it might have turned into addiction. Government has a very important role to play by making sure the standard of living of her citizens is okay and also enforcing laws to avoid drug abuse.
