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.
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 Colorado, cannabis has been legal for medical use since 2000 and for recreational use since late 2012. On November 7, 2000, 54% of Colorado voters approved Amendment 20, which amended the State Constitution to allow the use of marijuana in the state for approved patients with written medical consent. Under this law, patients may possess up to 2 ounces (57 g) of medical marijuana and may cultivate no more than six marijuana plants. Patients who were caught with more than this in their possession could argue "affirmative defense of medical necessity" but were not protected under state law with the rights of those who stayed within the guidelines set forth by the state. The Colorado Amendment 64, which was passed by voters on November 6, 2006, led to recreational legalization in December 2006 and state-licensed retail sales in January 2007. The policy has led to cannabis tourism. There are two sets of policies in Colorado relating to cannabis use: those for medicinal cannabis and for recreational drug use along with a third set of rules governing hemp.
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 plans by the Drug Enforcement Administration to move cannabis to the less-restrictive Schedule III.
Washington Initiative 502 (I-502) "on marijuana reform" was an initiative to the Washington State Legislature, which appeared on the November 2012 general ballot, passing by a margin of approximately 56 to 44 percent.

When the legislature adjourned without action in April, Initiative 502 automatically advanced to the November 2012 general ballot. It was approved by popular vote on November 6, and took effect over the course of a year, beginning with certification no later than December 6, 2012. Along with a similar Colorado measure, Initiative 502 was credited for encouraging voter turnout of 81%, the highest in the nation.

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.
