A study that has not been peer-reviewed but rather published as part of a “discussion series” by a German labor journal is getting a lot of publicity. Time Magazine, Join Together, the Denver Post, and other outlets have published stories about the study. The study concludes that traffic fatalities are reduced in medical marijuana states because, as the author’s assert, “alcohol and marijuana are substitutes.” So, as substitutes, the authors contend that medical marijuana laws cause people to drink less and therefore not drive drunk. This is most certainly a spurious and coincidental relationship, however, as a large body of data points to other reasons why we have witnessed historic reductions in road fatalities over the last 20 years.
