Legalized Marijuana Is Spreading Through the US

Based on recent ballot initiatives, recreational marijuana use will be legal for about 20% of the US population.  Over 60% will live in states that permit medical marijuana usage.  The Marimekko chart below, based on data from,  groups all states and the District of Columbia by how it regulates marijuana usage:
