After California became the first state to legalize medical marijuana in 1996, other states followed, in part because of overwhelming voter support. According to a 2021 Pew Research Center survey, 91 percent of adults believe marijuana should be legal. Thirty-one percent of those surveyed favored legal medicinal use only, and 60 percent said they supported both medical and recreational use.
In recent years, state marijuana legalization has intensified at a rapid pace. Several states have migrated from legal medical marijuana to legalizing recreational marijuana use, while others have also established state programs to regulate marijuana sales and cultivation.
Along with the tide of state marijuana legalization, there are also signs of a possible federal law. In late 2020, the House of Representatives passed a bill to decriminalize marijuana at the federal level. Although the Senate has not approved it, President Biden has indicated his support.
