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.
