Drug-Impaired Driving: Marijuana and Opioids Raise Critical Issues for States

Marijuana and opioid use affect driving and can cause crashes. State highway safety offices are concerned: in a survey, virtually all said drugged driving is a problem and the majority rated it equal to or more important than driving while impaired by alcohol. States must find effective strategies to address impaired driving resulting from marijuana or opioids. This report should help states understand the key facts. It incorporates information from a February 2018 survey of state highway safety offices on their challenges and strategies for dealing with marijuana- and opioid-impaired driving. This report begins by describing the size of the Driving Under the Influence of Drugs (DUID) problem, using the best available data but pointing out the substantial limitations in these data. The next two sections discuss marijuana and opioids, respectively: how frequently each is used and what is known about how each affects driving ability and crash risk. These sections document current state laws, active legislation, and public knowledge and attitudes regarding marijuana and opioids. The next section documents current state DUID detection, arrest, and prosecution strategies that apply to marijuana or opioids. It discusses legal and policy issues that may hinder these strategies. Finally, the report provides recommendations for what states can and should do to address marijuana- and opioid-impaired driving within their impaired driving programs.
