The toughest policies - the highest use. It would be hilarious if it
wasn't so tragic.

United States Has Highest Level Of Illegal Cocaine And Cannabis Use

ScienceDaily (July 1, 2008) — A survey of 17 countries has found that
despite its punitive drug policies the United States has the highest
levels of illegal cocaine and cannabis use. The study, by Louisa
Degenhardt (University of New South Wales, Sydney, Australia) and
colleagues, is based on the World Health Organization's Composite
International Diagnostic Interview (CIDI).

The authors found that 16.2%% of people in the United States had used
cocaine in their lifetime, a level much higher than any other country
surveyed (the second highest level of cocaine use was in New Zealand,
where 4.3%% of people reported having used cocaine). Cannabis use was
highest in the US (42.4%%), followed by New Zealand (41.9%%).

In the Americas, Europe, Japan, and New Zealand, alcohol had been used by
the vast majority of survey participants, compared to smaller proportions
in the Middle East, Africa, and China.
