5 States Most Likely to Legalize Cannabis in 2025: The Next Wave of Marijuana Reform

5 States on the Verge of Legalizing Cannabis in 2025

The movement to legalize recreational cannabis continues to gain traction across the United States. With 24 states already allowing adult-use marijuana, several others are poised to follow suit in 2025. Legislative efforts, growing public support, and shifting political landscapes are fueling the push for legalization in multiple regions.

While numerous states are considering marijuana reform, these five states stand out as the most likely to pass legalization measures this year.

1. Hawaii: A Push for a Constitutional Amendment

Hawaii lawmakers are making another attempt to bring recreational marijuana to the islands. House Bill 519, introduced by Representatives Gene Ward (R) and Kim Iwamoto (D), seeks to place a constitutional amendment on the November 2025 ballot. If passed, the amendment would allow adults 21 and older to possess and consume cannabis while granting the state legislature the power to regulate its distribution, taxation, and use.

Hawaii came close to legalization in 2024 when a bill cleared the Senate with a 19-6 vote and advanced through multiple House committees. However, it was blocked before reaching a full House vote. Advocates remain optimistic, as a recent survey found 52% of Hawaiian adults support legalization, compared to just 31% opposed. With growing public pressure, 2025 could finally be the year that Hawaii embraces legal cannabis.

2. New Hampshire: Strong Legislative Efforts Continue

New Hampshire has been steadily working toward cannabis legalization, and 2025 may be the year it happens. Lawmakers are considering multiple bills, including House Bill 75, which would legalize recreational cannabis for adults 21 and older, remove marijuana from the state's controlled substances list, and expunge past cannabis-related convictions. Another proposal, House Bill 186, is also set for discussion and aims to establish a regulatory framework for legal cannabis sales.

Although a previous legalization bill passed the Senate but failed narrowly in the House, the political landscape is evolving. Governor-elect Kelly Ayotte has expressed opposition to legalization but has not confirmed whether she would veto a bipartisan bill. With 65% of New Hampshire voters supporting legalization, according to recent polls, lawmakers may be motivated to push forward.

3. Pennsylvania: Governor’s Support Could Be a Game-Changer

Pennsylvania is moving closer to recreational cannabis legalization, with Governor Josh Shapiro announcing that his upcoming budget proposal will include provisions for legal cannabis sales. A bipartisan bill allowing adults to possess up to 30 grams of marijuana and establishing a regulatory framework is expected to be reintroduced soon.

The state's political climate is also shifting in favor of legalization. With Democrats maintaining a narrow majority in the House, there is increased momentum to advance cannabis reform. Majority Leader Matt Bradford has signaled the House’s readiness to pass legalization measures, while pressure is mounting on the Senate to take action. Polling data indicates that over 60% of Pennsylvanians support a regulated cannabis market, suggesting broad public backing for the initiative.

4. Wisconsin: Public Support Driving the Conversation

Wisconsin Governor Tony Evers has made cannabis legalization a key priority for 2025, signaling strong executive support for reform. While Democrats remain in the minority in the state legislature, they gained seats in the 2024 election, and bipartisan conversations about legalization are increasing.

A poll conducted by the Tarrance Group in August 2024 found that over 60% of Wisconsin residents favor legalizing marijuana for adult use. This widespread public support is adding pressure on lawmakers to take action. With neighboring states already benefiting from cannabis tax revenue, Wisconsin legislators may be compelled to follow suit.

5. Kentucky: A Surprising Contender for Legalization

Kentucky has long been seen as a conservative stronghold on cannabis policy, but recent developments suggest that the state may be moving toward reform. Multiple bills have been introduced in 2025, including Senate Bill 36 and House Bill 105, which propose a constitutional amendment to legalize adult-use cannabis. These measures would allow individuals to possess up to one ounce of cannabis, cultivate up to five plants, and establish a regulated market overseen by the General Assembly.

Additionally, Senate Bill 33 seeks to decriminalize the possession of up to eight ounces of cannabis and the cultivation of up to five plants. While Kentucky remains the least likely state on this list to legalize cannabis in 2025, the momentum behind these proposals is undeniable.

The Road Ahead: What to Expect in 2025

While each of these states faces unique political challenges, growing public support and shifting attitudes toward cannabis suggest that legalization efforts will continue to gain ground. With Hawaii, New Hampshire, Pennsylvania, Wisconsin, and Kentucky leading the charge, 2025 could be another pivotal year for cannabis reform in the United States.
