Cannabis legalization and driving under the influence of cannabis in a national U.S. Sample.

ABSTRACT: The relationship between cannabis legalization and traffic safety remains unclear. Physiological measures of cannabis impairment remain imperfect. This analysis used self-report data to examine the relationship between cannabis legalization and driving under the influence of cannabis (DUIC). Using a cross-sectional national sample (2016-2017) of 1,249 past-30-day cannabis users, we regressed self-reported DUIC (driving within three hours of "getting high") on cannabis legalization (recreational and medical (recreational), medical only (medical), or no legal cannabis), adjusting for demographics, days of use (past 30 days), days of use*legal status, calibration weights, and geographic clustering. The risk of DUIC in recreational (risk ratio [RR] = 0.41, 95% confidence interval (CI):0.23-0.7
