Eleven countries studied, one inescapable conclusion – the drug laws don’t work
Making drugs legally available in pharmacies would lead to: 
(1) organised crime looses a large chunk of its business, 
(2) no need for dealers to advertise to new users, they won't get the business anyways, 
(3) drugs would have medical-grade quality control and likely be cheaper than on the black market, 
(4) drugs can be taxed and this money can go into prevention and medical care,
(5) users are less likely to need to commit crimes to support their habit, 
(6) resources in law enforcement get freed for other things.The ethical question is if drug use would go up and thus a legalise-drugs policy would be guilty of leading people down a bad and potentially deadly path.  If the article is right that won't be so.
