Cannabis, or marijuana, has come a long way on the road back to legitimacy in the United States, and it soon may pass an important milestone: rescheduling. That’s the technical term for reclassifying it as a less dangerous drug, which would loosen some restrictions around it at the federal level.

Cannabis was widely used as medicine in the 1800s and early 1900s. But Congress effectively criminalized it in 1937 with passage of the Marihuana Tax Act. However, starting in 1996, marijuana has since become accessible in most states for adult medical or recreational use.

But it’s a different story at the federal level. Currently, cannabis is a Schedule I drug, under the Controlled Substance Act, alongside drugs such as heroin and LSD. By definition, Schedule I drugs have a high potential for abuse and no currently accepted medicinal use. The US Department of Justice is in the process of considering moving marijuana from a Schedule I to a less-restricted Schedule III drug.

Rescheduling cannabis is a complicated process. President Joe Biden officially requested the shift in 2022, and it involves multiple agencies, including the US Drug Enforcement Administration and the US Department of Health and Human Services.
