Oral fluid testing for marijuana intoxication: enhancing objectivity for roadside DUI testing

As of 2016, eight U.S. states and the District of Columbia have legalized marijuana for recreational use. One of those states, Colorado, has seen an increase in the proportion of fatal motor vehicle crashes involving drivers testing positive for marijuana. This study focuses on the use of oral fluid (OF) testing, which has become a common mechanism for roadside drug testing in high-income countries. OF tests involve swabbing the inside of the mouth, offering a minimally invasive procedure with a rapid analysis time that allows for the identification of intoxication on-site. Nine European countries, Australia and New Zealand allow on-site testing for drugged driving, and this article offers an analysis of a 2009 Belgium policy requiring on-site OF testing. The authors also examine legal issues associated with OF testing, and they consider the how the Belgium policy may inform policymakers in U.S. states where marijuana has been legalized, decriminalized, or made available for medical use.
