In the 2010s, there were several efforts to legalize the recreational use of marijuana, but none were successful. However, support for legalization did increase in the state;
Washington Post-
University of Maryland polls found that 54% of Marylanders supported legalization in 2014, and 61% supported legalization in 2016. In 2017, legalization was introduced in the state legislature (sponsored by Democratic Delegate
Curt Anderson, Democratic Senator
Richard Madaleno, and others) to legalize, tax, and regulate recreational marijuana in the state. The bills would have allowed persons 21 or older to lawfully possess up to of marijuana and grow up to six marijuana plants and would impose a
excise tax for cultivators and a 9 percent sales tax for buyers (the same sales tax as for alcohol sales in Maryland). The legislation also contained a provision that would expunge prior convictions for possession of marijuana in those amounts or less. The legislation did not pass. In 2021, Delegate
Jazz Lewis, a Democrat from
Prince George's County, introduced H.B. 32, which would legalize the adult use of recreational marijuana and expunge prior cannabis related convictions. Another marijuana legalization bill that had been brought up in 2021 is SB 708, which had been introduced by State Senator
Brian Feldman, a Democrat from
Montgomery County. Feldman and Lewis were reportedly working to "harmonize" the two bills. On July 16, 2021,
Maryland House of Delegates Speaker
Adrienne A. Jones announced that a referendum should decide whether to legalize recreational use of cannabis and that the House would pass legislation early next year to put this question before the voters. She also formed a bipartisan work group to work out the myriad details that such legalization would entail, from changes to criminal laws to the taxing structure.
2022 referendum In February 2022, Maryland lawmakers filed House Bill 837 in anticipation of voter approval of a ballot question in the November 2022 election; this bill would legalize recreational possession and use of cannabis on or after July 1, 2023. Furthermore, the bill would allow adults 21 and older to purchase and possess up to of marijuana, decriminalize possession of amounts greater than that up to , and allow the General Assembly to set a tax rate on the sale of marijuana. This bill would also establish a Cannabis Business Assistance Fund to support equity initiatives for minority- and women-owned businesses. The aforementioned fund would go toward incubator and educational programs to promote participation in the industry by people most impacted by criminalization. The bill would also automatically
expunge prior criminal convictions for conduct made legal under the proposed law. In April 2022, Governor Larry Hogan allowed the abovementioned bill to become law — with no action of a signature or veto to legalize cannabis recreationally within Maryland. Medicinal cannabis was already legal in Maryland. However, another bill that passed the
Maryland General Assembly in April 2022, House Bill 1, put the same cannabis policy onto the ballot as an initiative for Maryland voters to implement in the November 2022 election, negating the need for the governor's signature. Voters approved the
2022 Maryland Question 4 referendum on November 8, 2022, with 67.2% of voters in favor. It took effect on July 1, 2023. Both chambers reached a compromise bill with 9% tax and other provisions, and a vote was slated for April 10, the last day of the legislative session. On April 8, 2023, the Maryland General Assembly established rules for the recreational sale of cannabis. Under the new rules, people who are age 21 and older will be able to buy recreational cannabis in Maryland from July 1. The legislation also addresses commerce-related issues such as the number and types of cannabis business licenses that will be available. It sets the amount of sales tax those businesses must charge as well. As of September 2023, the Maryland Cannabis Administration (MCA) has issued cannabis dispensary licenses to 101 entities. In July 2023, Maryland's first month of regulated adult-use cannabis sales, retailers reported nearly $85 million in sales. ==Medical cannabis==
