Hong Kong (CNN) -- The global war on drugs is failing, new research suggests, as the price of heroin, cocaine and cannabis has fallen while their purity has increased.
Using seven sets of government drug surveillance data, a team of Canadian and U.S. researchers reviewed drug supply in the United States, Europe and Australia and drug production in regions such as Latin America, Afghanistan and Southeast Asia.
They found that illegal drugs have become cheaper while their potency has increased, indicating that efforts to control "the global illegal drug market through law enforcement are failing."
