CPRD recently presented the results of research combining the Illinois Youth Survey results and data on marijuana dispensary locations around the state to examine whether dispensary locations may have an effect on increasing youth use of marijuana. Initial results, presented in the figure above, suggests no relationshipo or a very limited relationship if any. This subject probably warrants further research, especially as medical marijuana dispensaries are set to become recreational marijuana dispensaries as of July 1, 2020 in Illinois.

This research was recently presented at the Research Society on Marijuana Annual Conference in Vancouver, Washington.
