Legalization of medical marijuana is not linked with increased traffic fatalities, a new study finds. In some states, in fact, the number of people killed in traffic accidents dropped after medical marijuana laws were enacted.
“Instead of seeing an increase in fatalities, we saw a reduction, which was totally unexpected,” said Julian Santaella-Tenorio, the study’s lead author and a doctoral student at Columbia University’s Mailman School of Public Health in New York City.
Since 1996, 28 states have legalized marijuana for medical use.
Deaths dropped 11 percent on average in states that legalized medical marijuana, researchers discovered after analyzing 1.2 million traffic fatalities nationwide from 1985 through 2014.
The decrease in traffic fatalities was particularly striking – 12 percent – in 25- to 44-year-olds, an age group with a large percentage of registered medical marijuana users, the authors report in the American Journal of Public Health.
