Where Is Marijuana Legalized?

Marijuana use was legal for most of human history until the early 20th century. Between 1916 and 1931, 29 U.S. states banned the use of marijuana. The Marihuana Tax Act of 1937 essentially made cannabis illegal across the U.S.

What's next for marijuana legalization?

Both medical and recreational marijuana use remains federally illegal, with the Controlled Substances Act of 1970 classifying cannabis as a Schedule I drug. Despite this classification, which is reserved for substances with no accepted medical use and a high potential for abuse, the medicinal benefits of marijuana are hard to dispute.

More states are likely to legalize medical and recreational marijuana in the coming years. As public support keeps increasing, and the number of marijuana stocks are rapidly proliferating, more states are considering the potential tax revenue benefits from cannabis sales.

Efforts are also underway in the U.S. Congress to enact major cannabis reform at the federal level. The U.S. House of Representatives passed a bill in April 2022 that would legalize cannabis throughout the U.S. However, the legislation seems unlikely to receive a vote in the U.S. Senate.
