As part of a wider survey on drug use patterns and harms conducted at the end of 2011 by Global Drug Survey (www.globaldrugsurvey.com), in partnership with Mixmag and the Guardian newspaper, we asked current cannabis smokers about the risk of being identified as intoxicated with cannabis (without alcohol) while driving if they were pulled over by the police within two hours of smoking a joint.1 2 We obtained data from more than 10 000 cannabis users from around the world. The table⇓ outlines the results from the UK, US, and Australia. The findings support Hall’s cautious view on the likely impact of roadside drug testing on driving while under the influence of drugs. For any drug driving policy to be an effective deterrent, drivers must consider the risk of being stopped and subsequently detected a real possibility.
