Drugged Driving now more widespread than Drunk Driving: “This report, originally released in September 2015, was prepared by Dr. James Hedlund under contract with the Governors Highway Safety Association (GHSA), the national association of state and territorial highway safety offices that address behavioral highway-safety issues, including drug-impaired driving. An open forum on drugged driving at GHSA’s 2014 Annual Meeting noted the need for this type of resource. Funding was provided by the Foundation for Advancing Alcohol Responsibility (Responsibility.org). This revision, also prepared by Dr. Hedlund, updated the report to April 2017. It includes 34 additional citations, drug-impaired driving data from 2015, state laws as of April 2017, and 15 state programs The report was guided by an advisory panel of experts from the states, the research community, and several organizations concerned with impaired driving. It provides references to research and position papers, especially papers that summarize the research on drugs and driving that have appeared in the last 20 years. It includes information obtained by GHSA from a survey of state highway safety offices. It does not attempt to be a complete review of the extensive information available on drugs and driving.”
