The Marijuana Policy Project (MPP) is the largest organization working solely on marijuana policy reform in the United States in terms of its budget, number of members, and staff.
In the United States, increased restrictions and labeling of cannabis as a poison began in many states from 1906 onward, and outright prohibitions began in the 1920s. By the mid-1930s cannabis was regulated as a drug in every state, including 35 states that adopted the Uniform State Narcotic Drug Act. The first national regulation was the Marihuana Tax Act of 1937.
In the United States, the use of cannabis for medical purposes is legal in 38 states, four out of five permanently inhabited U.S. territories, and the District of Columbia, as of March 2023. Ten other states have more restrictive laws limiting THC content, for the purpose of allowing access to products that are rich in cannabidiol (CBD), a non-psychoactive component of cannabis. There is significant variation in medical cannabis laws from state to state, including how it is produced and distributed, how it can be consumed, and what medical conditions it can be used for.
Gonzales v. Raich, 545 U.S. 1 (2005), was a decision by the U.S. Supreme Court ruling that, under the Commerce Clause of the U.S. Constitution, Congress may criminalize the production and use of homegrown cannabis even if state law allows its use for medicinal purposes.
In the United States, cannabis is legal in 38 of 50 states for medical use and 24 states for recreational use. At the federal level, cannabis is classified as a Schedule I drug under the Controlled Substances Act, determined to have a high potential for abuse and no accepted medical use, prohibiting its use for any purpose. Despite this prohibition, federal law is generally not enforced against the possession, cultivation, or intrastate distribution of cannabis in states where such activity has been legalized.
The legal history of cannabis in the United States began with state-level prohibition in the early 20th century, with the first major federal limitations occurring in 1937. Starting with Oregon in 1973, individual states began to liberalize cannabis laws through decriminalization. In 1996, California became the first state to legalize medical cannabis, sparking a trend that spread to a majority of states by 2016. In 2012, Washington and Colorado became the first states to legalize cannabis for recreational use.
Cannabis in South Dakota is legal for medical use as of July 1, 2021, having been legalized by a ballot initiative on November 3, 2020. Prior to then, cannabis was fully illegal, with South Dakota being the only U.S. state which outlawed ingestion of controlled substances. Testing positive for cannabis can be a misdemeanor offense. South Dakota would have become the first state in US history to legalize recreational and medical cannabis simultaneously, but an amendment legalizing recreational marijuana that was approved in the same election was struck down as unconstitutional the following February. The challenge claimed the amendment violated Amendment Z, the "Single-Subject Rule". The decision was appealed to the South Dakota Supreme Court, which upheld the lower court's decision on November 24, 2021.

The Florida Medical Marijuana Legalization Initiative, also known as Amendment 2, was approved by voters in the Tuesday, November 8, 2016, general election in the State of Florida. The bill required a super-majority vote to pass, with at least 60% of voters voting for support of a state constitutional amendment. Florida already had a medical marijuana law in place, but only for those who are terminally ill and with less than a year left to live. The goal of Amendment 2 is to alleviate those suffering from these medical conditions: cancer, epilepsy, glaucoma, positive status for human immunodeficiency virus (HIV), acquired immune deficiency syndrome (AIDS), post-traumatic stress disorder (PTSD), amyotrophic lateral sclerosis (ALS), Crohn's disease, Parkinson's disease, multiple sclerosis, chronic nonmalignant pain caused by a qualifying medical condition or that originates from a qualified medical condition or other debilitating medical conditions comparable to those listed. Under Amendment 2, the medical marijuana will be given to the patient if the physician believes that the medical use of marijuana would likely outweigh the potential health risks for a patient. Smoking the medication was not allowed under a statute passed by the Florida State Legislature, however this ban was struck down by Leon County Circuit Court Judge Karen Gievers on May 25, 2018.

The Donald Trump administration took positions against marijuana and against the easing of laws regarding marijuana. Although Trump indicated during his 2016 presidential campaign that he favored leaving the issue of legalization of marijuana to the states, his administration subsequently upheld the federal prohibition of cannabis, and Trump's 2021 fiscal budget proposal included removing protections for state medical marijuana laws. In 2018, the administration rescinded the 2013 Cole Memorandum, an Obama-era Justice Department policy that generally directed federal prosecutors not to pursue marijuana prosecutions in states where marijuana is legal as a matter of state law.

U.S. President Joe Biden stated in February 2021 that his administration will pursue cannabis decriminalization as well as seek expungements for people with prior cannabis convictions. It can still be found on his campaign website under sentencing reform. As of October 2022, Biden pardoned thousands of people convicted of marijuana possession under federal law. However, according to the Marshall Project, nobody was released from prison as a result of the October 2022 pardons, as no federal inmates were incarcerated for simple marijuana use at the time.
