Yet Another Study Finds No Link Between Cannabis Legalization And Traffic Casualties

Once again, yet another study finds that recreational cannabis legalization and retail commercialization did NOT lead to an increase in fatal or injury traffic crashes.  This study looked at Washington State, one of the first two states to legalize cannabis for recreational use, and actually found that legalization itself led to fewer fatal and injury crashes, while commercialization (retail sales) led to no statistically significant impacts on fatal or injury crashes (albeit correlated with a modest increase in non-injury crashes, likely from tourists).  These results jibe well with survey data that did not find a significant change in driving behavior while under the influence, despite a self-reported increase in cannabis use in general. 

These results dovetail rather nicely with several other studies in both the USA as well as Canada.

In other words, the fear that legalization or retail sales would cause carnage on the highways has turned out to be unfounded.  Look like yet another card in the prohibitionists' vast rolodex full of myths, lies, and half-truths needs to be retired for good.

UPDATE:  Also, a new study found that mental health treatment admissions actually go DOWN following recreational cannabis legalization.
