In the United States, the removal of cannabis from Schedule I of the Controlled Substances Act is a proposed legal and administrative change in cannabis-related law at the federal level. It has been proposed repeatedly since 1972. The category is the most tightly restricted category reserved for drugs that have "no currently accepted medical use."
In the United States, the non-medical use of cannabis is legalized in 24 states and decriminalized in 7 states, as of November 2023. Decriminalization refers to a policy of reduced penalties for cannabis offenses, typically involving a civil penalty for possessing small amounts, instead of criminal prosecution or the threat of arrest. In jurisdictions without penalty the policy is referred to as legalization, although the term decriminalization is sometimes used for this purpose as well.
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.
The use, sale, and possession of cannabis containing over 0.3% THC by dry weight in the United States, despite laws in many states permitting it under various circumstances, is illegal under federal law. As a Schedule I drug under the federal Controlled Substances Act (CSA) of 1970, cannabis containing over 0.3% THC by dry weight is considered to have "no accepted medical use" and a high potential for abuse and physical or psychological dependence. Cannabis use is illegal for any reason, with the exception of FDA-approved research programs. However, individual states have enacted legislation permitting exemptions for various uses, including medical, industrial, and recreational use.
Cannabis in Oregon is legal for both medical and recreational use. In recent decades, the U.S. state of Oregon has had a number of legislative, legal, and cultural events surrounding use of cannabis. Oregon was the first state to decriminalize the possession of small amounts of cannabis, and among the first to authorize its use for medical purposes. An attempt to recriminalize possession of small amounts of cannabis was turned down by Oregon voters in 1997.
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.
Cannabis in California has been legal for medical use since 1996, and for recreational use since late 2016. The state of California has been at the forefront of efforts to liberalize cannabis laws in the United States, beginning in 1972 with the nation's first ballot initiative attempting to legalize cannabis. Although it was unsuccessful, California would later become the first state to legalize medical cannabis through the Compassionate Use Act of 1996, which passed with 56% voter approval. In November 2016, California voters approved the Adult Use of Marijuana Act with 57% of the vote, which legalized the recreational use of cannabis.
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. On May 1, 2024, the Associated Press reported on federal plans to change marijuana to a Schedule III drug.
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 Massachusetts is legal for medical and recreational use. It also relates to the legal and cultural events surrounding the use of cannabis. A century after becoming the first U.S. state to criminalize recreational cannabis, Massachusetts voters elected to legalize it in 2016.
The Ending Federal Marijuana Prohibition Act is a series of federal marijuana decriminalization bills that have been introduced multiple times in the United States Congress.
Cannabis on American Indian reservations historically largely fell under the same regulations as cannabis nationwide in the United States. However, the August 2013 issuance of the Cole Memorandum opened discussion on tribal sovereignty as pertains to cannabis legalization, which was further explored as the states of Washington and Colorado legalized marijuana. A clarifying memo in December 2014 stated that the federal government's non-interference policies that applied to the 50 states, would also apply to the 326 recognized American Indian reservations. U.S. Attorney for Oregon, Amanda Marshall, stated that the clarification had been issued in response to legal questions from tribal nations, but that only three unnamed tribes, in California, Washington state, and "the Midwest" had stated explicit interest in legalizing.
Cannabis in Wisconsin is illegal for recreational use. Possession of any amount is punishable by up to 6 months in prison and a $1000 fine for a first offense. A second offense is punished as a felony with up to 3.5 years in prison and up to a $10,000 fine. At the local level, however, numerous municipalities and counties have decriminalized cannabis or lessened penalties for minor possession offenses. Medical use is legal only in the form of low-THC cannabis oil.
Cannabis in Texas is illegal for recreational use. Possession of up to two ounces is a class B misdemeanor, punishable by up to 180 days in prison and a fine of up to $2000. Several of the state's major municipalities have enacted reforms to apply lesser penalties or limit enforcement, however.
Cannabis in Washington relates to a number of legislative, legal, and cultural events surrounding the use of cannabis. On December 6, 2012, Washington became the first U.S. state to legalize recreational use of marijuana and the first to allow recreational marijuana sales, alongside Colorado. The state had previously legalized medical marijuana in 1998. Under state law, cannabis is legal for medical purposes and for any purpose by adults over 21.
Cannabis in Mexico is legal for both recreational and medicinal purposes. It became legal for recreational purposes in June 2021, upon application and issuance of a permit from the health secretariat, COFEPRIS. On 29 June 2021, the Supreme Court of Mexico decriminalized the recreational use of cannabis. President Andrés Manuel López Obrador signed a bill that allows adults 18 and over to possess up to 28 grams of cannabis and grow up to six marijuana plants on their property.
The Cole Memorandum was a United States Department of Justice memorandum issued August 29, 2013, by United States Deputy Attorney General James M. Cole during the presidency of Barack Obama. The memorandum, sent to all United States Attorneys, governed federal prosecution of offenses related to marijuana. The memo stated that given its limited resources, the Justice Department would not enforce federal marijuana prohibition in states that "enacted laws legalizing marijuana in some form and ... implemented strong and effective regulatory and enforcement systems to control the cultivation, distribution, sale, and possession of marijuana," except where a lack of federal enforcement would undermine federal priorities.
The 2018 farm bill or Agriculture Improvement Act of 2018 is an enacted United States farm bill that reauthorized $867 billion for many expenditures approved in the prior farm bill. The bill was passed by the Senate and House on December 11 and 12, 2018, respectively. On December 20, 2018, it was signed into law by President Donald Trump.
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.
