Ayotte’s Medical Cannabis Veto Becomes a Campaign Issue

A vetoed bill that would have let New Hampshire’s medical marijuana providers grow cannabis in greenhouses to lower patient costs has become a talking point in the state’s race for governor.

Cinde Warmington, the most prominent Democrat vying to challenge Republican Gov. Kelly Ayotte this fall, has seized on the veto to hit the incumbent over healthcare affordability, the theme at the center of her campaign. Ayotte vetoed the measure last month, and Warmington moved quickly to turn it into a line of attack.

A veto becomes a campaign attack

Warmington, a health care attorney who served four years on the New Hampshire Executive Council, framed the veto as one more example of the governor raising costs for residents. In a post to her campaign account, she wrote, “Making medical cannabis more expensive for Granite Staters? Come on, Kelly.”

She linked the decision to Ayotte’s broader record, pointing to higher Medicaid premiums and prescription co-pays under the current administration. Warmington, whose campaign for governor is built around the cost of living, argued the state should be working to lower healthcare costs rather than add to them.

The attack fits a familiar pattern for Warmington, who ran for governor in 2024 and has spent her career in health care. Ayotte, a first-term governor and former U.S. senator, is favored for reelection, but Democrats have made affordability their central argument against her, echoing a message the party has pushed nationally. A medical program that thousands of patients depend on gives Warmington a concrete, local example to point to, one that ties a cannabis policy fight to the kitchen-table costs her campaign talks about most.

What the vetoed bill would have done

The measure, Senate Bill 468, would have let the state’s licensed medical cannabis operators apply to the health department to run a greenhouse cultivation site, either at their existing location or a separate one. To win approval, an operator would have had to show the change would cut energy costs and lower prices, then report back to regulators each year. Greenhouses draw far less electricity than the fully enclosed indoor grows the state now requires, and supporters said those savings would reach patients at the register.

The bill cleared both the Senate and House on voice votes with bipartisan support, and drew only one opponent in testimony this session, the head of a New Hampshire group that opposes marijuana legalization.

New Hampshire’s therapeutic cannabis program, established in 2013, serves more than 12,000 registered patients through a small group of nonprofit alternative treatment centers that grow, process, and dispense the state’s medical marijuana. Those operators must currently cultivate indoors in fully enclosed, secured facilities, an energy-intensive requirement that backers of the bill blame for keeping prices high.

The governor’s veto message was brief. “I do not support expanding the cultivation of marijuana in our state,” Ayotte wrote, offering no further explanation.

The push to override

The bill’s sponsors are not letting the veto stand quietly. Sen. Howard Pearl, the Republican who led the legislation, and Sen. Tara Reardon, a Democratic co-sponsor, both say they want lawmakers to override it, arguing the change would have lowered costs for seriously ill patients without weakening the program’s safeguards. Reardon said the veto denies savings to the thousands of patients and veterans who rely on medical cannabis as part of their care.

Reversing a governor’s veto in New Hampshire is hard. It takes a two-thirds vote in both chambers, which the legislature will weigh when it reconvenes for a veto session later this year. It can be done: Delaware lawmakers recently overrode a veto on a cannabis zoning bill. But the math is steep, and the bipartisan voice votes that carried the bill the first time do not guarantee the wider margin an override demands. In 2024, then-Gov. Chris Sununu vetoed a nearly identical greenhouse proposal; the House had the votes to override, but the Senate fell short. Ayotte’s action makes it the second time in two years that a New Hampshire governor has blocked the idea.

Ayotte’s resistance runs deeper than this one bill. She has pledged to veto any adult-use legalization measure that reaches her desk, leaving New Hampshire the only New England state without a legal recreational market even as other states widen access, with Iowa recently doubling its medical dispensary cap. For patients, the practical question is whether the override push can find the votes this fall. If it can’t, the greenhouse option, and the lower prices its backers promised, stays off the table until a future legislature, or a different governor, takes it up.
