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.
