I don't believe in a drug free place, it just gets moved to a more underground state and in smaller numbers, governments can squash it but it just pops up like a bad spot that won't go away, you cant fight what is normal imo !
That is the problem. Already the drug trade is underground. The latest crackdown will send it many layers below, to the deep-underground. It will be extremely hard for the NGOs and the charities to monitor the drug users. The incidence of HIV and deaths due to overdose are going to rise.
Very often I see that young people are often interested in soft drugs, due to the fact that they want to have fun. But it usually ends in tears. Because, as always, first light, and then the transition to hard drugs. These problems need to fight the whole world together.
