Abstract:

In July 2014, Washington State allowed legal sales of recreational marijuana. Working with the Washington Traffic Safety Commission, NHTSA assisted the State in conducting a roadside study to examine the prevalence of marijuana use before and after sales began. The study also examined drivers’ use of alcohol and other drugs. National roadside studies have been conducted approximately every decade since the 1970s. This study used a similar research design as the national studies but included several enhancements. It included more than 70 over-the-counter, prescription (antidepressants, sleep medications, etc.), and illegal drugs (cocaine, opioids, etc.) that may impair driving-related skills.
