Cannabis legalization in 2025 could create several new markets across the United States. Some states are considering adult-use sales, while others are working to establish medical cannabis programs.

For businesses and investors, understanding these developments is essential for strategic planning. With 2025 shaping up to be another important year, here are nine promising cannabis markets that could emerge or expand.

States Transitioning From Medical to Adult-Use Cannabis

Pennsylvania: The Keystone State Considers Recreational Cannabis

Pennsylvania could become one of the country’s largest new adult-use markets. Governor Josh Shapiro has publicly supported legalization, declaring, “It’s time to legalize it.”

The state has 13.1 million residents. It also welcomes 192.4 million visitors each year, generating approximately $76 billion in tourism spending. Together, these factors give Pennsylvania substantial market potential.

Pennsylvania’s medical cannabis program has already created much of the infrastructure needed for adult-use sales. Legislative proposals such as HB 2210 and SB 846 have also received bipartisan support.

Governor Shapiro continued urging lawmakers to approve legalization in 2025. If legislation passes, Pennsylvania could quickly become a major recreational cannabis market.

Hawaii: A Potential Tourism-Driven Market

Hawaii came close to legalizing recreational cannabis in 2024 through SB 669 and HB 1246. Although those efforts stalled, support for reform remained strong.

The state has approximately 1.4 million residents. However, Hawaii’s tourism industry greatly expands its potential customer base. The islands welcome about 9.5 million visitors annually, generating $17.75 billion in tourism spending.

Legalization efforts were expected to return in 2025. These proposals may place greater emphasis on social equity and the creation of an effective regulatory framework.

If successful, Hawaii could develop a unique market supported by both residents and tourists.

Virginia: Completing the Legalization Process

Virginia occupies an unusual position in the cannabis industry. Adult-use possession is legal, but retail sales remain prohibited.

Lawmakers previously made progress toward creating a regulated retail market. However, Governor Glenn Youngkin vetoed the legislation.

Advocates may attempt to override the veto or introduce another proposal. Either option could move the state closer to launching legal sales.

Virginia’s potential market is significant. The state has 8.8 million residents and welcomes approximately 43.6 million visitors each year. Those visitors generate an estimated $33.3 billion in annual spending.

New Medical Cannabis Markets

Kentucky: A Historic Medical Program Launch

Kentucky launched its medical cannabis program on January 1, 2025, following the passage of SB 47.

The launch represented a major policy shift for a state with a long history of cannabis prohibition. Kentucky has approximately 4.6 million residents and welcomes 79.3 million visitors annually.

Product access will initially be tightly regulated. However, the program creates a foundation for future growth and possible adult-use legislation.

South Carolina: Medical Cannabis Gains Momentum

South Carolina moved closer to legalizing medical cannabis when the state Senate passed the Compassionate Care Act, or SB 423, in 2024.

The state House was expected to consider the legislation in 2025. If approved, South Carolina could become one of the last Southern states to establish a medical cannabis program.

South Carolina has 5.3 million residents and welcomes approximately 30 million visitors annually. Tourism generates about $24 billion in spending, adding to the state’s potential as an emerging cannabis market.

Nebraska: Voter Approval Meets Implementation Challenges

Nebraska voters approved two medical cannabis ballot measures in November 2024.

Initiatives 437 and 438 legalized possession of up to five ounces of cannabis for medical use. They also established the Nebraska Medical Cannabis Commission.

However, the program faced several implementation challenges. Legislative Bill 677, which was intended to regulate the program, failed to advance from committee in April 2025.

Ongoing legal disputes and regulatory uncertainty further complicated the rollout. As a result, Nebraska’s 1.9 million residents may face delays in accessing the voter-approved program.

High-Potential States Without Legal Cannabis

Wisconsin: Pressure for Reform Builds

Wisconsin remains a major cannabis policy outlier in the Midwest. The state is surrounded by legal markets, including Illinois, Michigan, and Minnesota.

This contrast creates economic and political pressure for reform. Wisconsin residents can cross state lines to purchase cannabis, sending potential tax revenue to neighboring states.

The economic opportunity is substantial. Wisconsin has 5.9 million residents and welcomes approximately 113 million visitors annually. Those visitors generate about $22.2 billion in spending.

Although legalization remains uncertain, Wisconsin is an important market to watch in 2025.

Kansas: Growing Support for Medical Cannabis

Kansas remains one of the few states without any form of legal cannabis. However, public support for cannabis reform continues to grow.

Lawmakers have introduced several medical cannabis proposals in recent legislative sessions. In addition, the success of Missouri’s neighboring adult-use market may increase pressure for change.

Kansas has approximately 2.9 million residents and welcomes 36.5 million visitors annually. Because the state does not yet have a regulated program, it represents a largely untapped market.

South Dakota: Another Opportunity for Legalization

South Dakota has experienced a complicated legalization process. Voters approved adult-use cannabis in 2020, but the courts later overturned the measure.

Cannabis advocates continued their efforts and qualified another measure for the 2024 ballot.

South Dakota has approximately 919,000 residents. The state also attracts 14.5 million annual visitors, who generate an estimated $4.4 billion in tourism spending.

If legalization efforts succeed, South Dakota could finally establish a regulated adult-use cannabis market.
