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, cannabis is legal in 39 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. Beginning in 2024, the Drug Enforcement Administration has initiated a review to potentially move cannabis to the less-restrictive Schedule III.

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.
