“…For example, a recent study by Anderson and Rees concluded that per se drugged driving laws have not been effective in decreasing traffic fatality rates in states implementing these laws. 42 Policy makers should consider additional measures to increase primary prevention of drug use by drivers. For example, our study findings suggest that older drivers using drugs, including prescription medications, may be responsible for a growing share of road fatalities.…”

“…18,19 The later 4 covariates were coded as “1” if the state had the law in any given year and “0” otherwise. We also controlled for state-level graduated driver license laws, 20 blood alcohol content laws (0.08 g/dL), drug per se laws, 21 administrative license revocation laws, 22 and laws banning cell phone use and texting while driving, separately targeting adolescents and adults. 23 These later 5 covariates were coded as “1” if the state had the law in any given year and “0” otherwise; also, if the enactment of the law occurred during a calendar year, we coded that year as the proportion of the year the law was in effect.…”

Objectives To determine the association of medical marijuana laws (MMLs) with traffic fatality rates. Methods Using data from the 1985–2014 Fatality Analysis Reporting System, we examined the association between MMLs and traffic fatalities in multilevel regression models while controlling for contemporaneous secular trends. We examined this association separately for each state enacting MMLs. We also evaluated the association between marijuana dispensaries and traffic fatalities. Results On average, MML states had lower traffic fatality rates than non-MML states. Medical marijuana laws were associated with immediate reductions in traffic fatalities in those aged 15 to 24 and 25 to 44 years, and with additional yearly gradual reductions in those aged 25 to 44 years. However, state-specific results showed that only 7 states experienced post-MML reductions. Dispensaries were also associated with traffic fatality reductions in those aged 25 to 44 years. Conclusions Both MMLs and dispensaries were associated with reductions in traffic fatalities, especially among those aged 25 to 44 years. State-specific analysis showed heterogeneity of the MML–traffic fatalities association, suggesting moderation by other local factors. These findings could influence policy decisions on the enactment or repealing of MMLs and how they are implemented.

“…A strict THC limit above which drivers are automatically considered impaired may, in the future, be viewed by the public and policymakers as a necessary complement to legalizing recreational marijuana. However, there is little evidence that, as currently implemented, such limits actually improve roadway safety (Anderson & Rees, ). Given this lack of evidence, policymakers might consider lowering the BAC limit.…”
