An amazing study authored by professors D. Mark Anderson (University of Montana) and Daniel Rees (University of Colorado) shows that traffic deaths have been reduced in states where medical marijuana is legalized.

According to their findings, the use of medical marijuana has caused traffic related fatalities to fall by nearly nine percent in states that have legalized medical marijuana (via The Truth About Cars).

The study notes that this is equal to the effect raising the drinking age to 21 had on reducing traffic fatalities.

One key factor is the reduction in alcohol consumption. The study finds that there is a direct correlation between the use of marijuana and a reduction in beer sales, especially in the younger folks aged 20-29.

A drop in beer sales supports the theory that marijuana can act as a substitute for liquor.
