Four of them—Florida, Montana, North Dakota and Arkansas—will be voting on medical marijuana measures that either expand or establish the availability of cannabis for patients. Five others—California, Nevada, Arizona, Massachusetts and Maine—will be voting on whether to allow adults 21 and older to consume cannabis recreationally.
If all the measures pass, that would bring the total number of states with comprehensive medical marijuana laws to 28. (Several other states allow for limited medicinal uses.)
On the adult use side, the number of states would more than double—from four to nine—and population gains would be even bigger. While about 5% of the population currently lives in a place where weed is fully legal, nearly a quarter of the U.S. population could wake up on Nov. 9 in a place where pot can be consumed for fun.
