A recent study has been performed regarding the traffic deaths from 1990 to 2009. The study looked at data from all 50 states but focused in on the states that have passed medical marijuana legislation. It turns out that states with medical marijuana provision have had a 9% decrease in all traffic fatalities. The study was done by professors at the University of Oregon, Montana State University, and The University of Colorado-Denver. The study doesn’t address what the reason behind this decrease in traffic deaths is due to, but many people believe that more people are ingesting medical marijuana instead of alcohol. It would be interesting to see if the amount of alcohol sales dropped along with the traffic fatalities. If I hear any more information about this topic, I’ll be sure to keep you informed.
