By Steve Higgins | According to a new survey the USA has highest level of illegal cocaine and cannabis use in the world. Thank goodness the War for Drugs is working so well! Ohh… wait… that’s the war ON drugs and it’s supposed to protect us from ourselves and our nasty drug habits. Well anyway.. here’s the details on the study:
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) and is published in this week’s PLoS Medicine.
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.
The survey found differences in both legal and illegal drug use among different socioeconomic groups. For example, males were more likely than females to have used all drug types; younger adults were more likely than older adults to have used all drugs examined; and higher income was related to drug use of all kinds. Marital status was found to be related to tobacco, cannabis, and cocaine use, but not alcohol use (the never married and previously married having higher odds of lifetime cocaine and cannabis use than the currently married; tobacco use is more likely in people who have been previously married while less likely among the never married).
Drug use “does not appear to be simply related to drug policy,” say the authors, “since countries with more stringent policies towards illegal drug use did not have lower levels of such drug use than countries with more liberal policies.” In the Netherlands, for example, which has more liberal policies than the US, 1.9% of people reported cocaine use and 19.8% reported cannabis use.
Data on drug use were available from 54,068 survey participants in 17 countries. The 17 countries were determined by the availability of research collaborators and on funding for the survey. Trained lay interviewers carried out face-to-face interviews (except in France where the interviews were done over the telephone) using a standardized, structured diagnostic interview for psychiatric conditions and drug use. Participants were asked if they had ever used alcohol, tobacco, cannabis, or cocaine.
The study’s main limitations are that only 17 countries were surveyed, within these countries there were different rates of participation, and it is unclear whether people accurately report
their drug use when interviewed. Nevertheless, the findings present comprehensive data on the patterns of drug use from national samples representing all regions of the world.

So the take home messages… people in the U.S. have a bunch of disposable income for drugs and we really f’n love cocaine! Although (I should really look at the article directly), it doesn’t look like they check out the countries in which the cocaine was produced. I’d be curious to see a survey on a wider variety of countries.
And finally… the most important take home message: Drug Policy has NOTHING to do with drug use. We can put users, dealers, producers, cousins of uncles of friends of users, their dogs, cats, guinea pigs, or the lint under their couches in jail or to death and it will have no effect on whether people use drugs or not. Education however… just maybe that will help. Oh.. that and taxation – Heavy heavy taxation. After all tobacco use has gone drastically down in the last decade with more education and higher drug prices.
