Résumé :
ENGLISH:
OBJECTIVES: To evaluate motor vehicle crash fatality rates in the first 2 states with recreational marijuana legalization and compare them with motor vehicle crash fatality rates in similar states without recreational marijuana legalization.
METHODS: We used the US Fatality Analysis Reporting System to determine the annual numbers of motor vehicle crash fatalities between 2009 and 2015 in Washington, Colorado, and 8 control states. We compared year-over-year changes in motor vehicle crash fatality rates (per billion vehicle miles traveled) before and after recreational marijuana legalization with a difference-in-differences approach that controlled for underlying time trends and state-specific population, economic, and traffic characteristics.
RESULTS: Pre-recreational marijuana legalization annual changes in motor vehicle crash fatality rates for Washington and Colorado were similar to those for the control states. Post-recreational marijuana legalization changes in motor vehicle crash fatality rates for Washington and Colorado also did not significantly differ from those for the control states (adjusted difference-in-differences coefficient = +0.2 fatalities/billion vehicle miles traveled; 95% confidence interval = -0.4, +0.9).
CONCLUSIONS: Three years after recreational marijuana legalization, changes in motor vehicle crash fatality rates for Washington and Colorado were not statistically different from those in similar states without recreational marijuana legalization. Future studies over a longer time remain warranted.

Des scientifiques ont enquêté sur le nombre annuel de décès accidentels de véhicules automobiles entre 2009 et 2015 à Washington, au Colorado, et dans 8 États témoins. Ils ont constaté que "trois ans après la légalisation récréative de la marijuana, les changements dans les taux de mortalité accidentelle des véhicules à moteur pour Washington et le Colorado n'étaient pas statistiquement différents de ceux dans des états similaires sans légalisation de la marijuana récréative".
