How should we respond to cannabis impaired driving?

Professor Wayne Hall has recently published a editorial for "Drug and Alcohol Review" titled "How should we respond to cannabis-impaired driving?" In the article, Professor Hall describes a recent international symposium on drug impaired driving, which attempted to unpack this issue.  One of the primary problems with roadside saliva testing for cannabis use, is that these tests do not have any correlation with actual impairment caused by THC. This makes it difficult to assess whether or not roadside saliva testing for cannabis can have a road safety benefit and critics of the approach says that these types of test are designed to discourage cannabis use rather than protect public safety.  In this article, Professor Hall describes the challenges related to responding to cannabis-impaired driving and describes the areas of research that are needed to adequately respond to these challenges.
