As many across the country celebrate the unofficial marijuana holiday, Vox compiled 24 maps and charts that explain marijuana, its history, and the policies that surround it.

The visualizations are based on data from a variety of sources such as the Centers for Disease Control and Prevention, the Office of National Drug Control Policy, the National Survey on Drug Use and Health, the Economist, Gallup, the Pew Research Center, and the Marijuana Policy Project.
