The Marijuana Opportunity Reinvestment and Expungement Act, also known as the MORE Act, is a proposed piece of U.S. federal legislation that would deschedule cannabis from the Controlled Substances Act and enact various criminal and social justice reforms related to cannabis, including the expungement of prior convictions. Introduced in 2019, the U.S. House of Representatives passed the bill on December 4, 2020, marking the first time a chamber of Congress approved legislation to end federal marijuana prohibition.
