The latest in a series of polls ahead of the November elections continues to show that a sizable majority Massachusetts voters oppose a measure on the ballot that would roll back the state’s marijuana legalization law.
The new survey, published on Tuesday by CommonWealth Beacon and conducted by MassINC Polling Group (MPG), shows that 61 percent of likely voters oppose the initiative—which would repeal laws allowing the regulated commercial sales of recreational cannabis and home cultivation while maintaining legal possession and continuing the medical marijuana system.
Just 27 percent of respondents said they favor the anti-cannabis ballot measure, while 11 percent are undecided and 1 percent responded that they would prefer not to state their opinion.
No age, race, geographic of political demographic showed majority support for rolling back marijuana legalization in the survey, though Republicans were twice as likely to back the anti-cannabis initiative (42 percent) than Democrats were (21 percent).
The poll also shows that the marijuana legalization repeal has less support than any other measure on the November ballot, except for a veto referendum question for which a “yes” vote will keep a 2024 gun law in effect and a “no” vote will repeal it.
The survey additionally asked voters to list their top issues on the ballot, finding that marijuana and guns were the only measures that people cited as reasons to vote.
“Those are your two marquee ones that were actually drawing people out,” MPG vice president Rich Parr said.
The poll included interviews with 800 likely voters between September 14-22, 2026 and has a margin of error of +/- 4 percentage points.
A separate poll released last week by The University of New Hampshire, shows that nearly three-quarters (71 percent) of respondents plan to vote against the anti-cannabis measure, while just 24 percent plan to support it.
Another survey released last month found that Massachusetts voters oppose the marijuana legalization repeal measure, 55 percent to 33 percent.
The Massachusetts Cannabis Control Commission, which regulates the legal industry, announced this month that the state has surpassed $10 billion in adult-use cannabis purchases since the market launched in 2018.
CCC Chair Chris Harding told Marijuana Moment that he can’t comment directly on the initiative and that the commission does not take positions on pending ballot questions or legislation, but he said that, in general, “repeal of the adult-use industry could eliminate thousands of jobs, hundreds of businesses and billions in tax revenue.”
Meanwhile, a top labor union—the Service Employees International Union (SEIU) Massachusetts State Council—is urging voters to reject the cannabis legalization rollback initiative.
While the latest survey results provide some comfort to cannabis reform supporters, advocates are not resting.
A coalition of Massachusetts marijuana business leaders, healthcare professionals and other advocates have launched a campaign to defeat the measure.
The Marijuana Policy Project (MPP) recently issued a warning that passage of the legalization rollback measure would have “disastrous political and economic consequences for legal cannabis markets everywhere.”
“Even a too-close victory would spook markets and incentivize a rash of similar initiatives in states around the country, each costing millions to try and defeat,” the group said.
After the Secretary of the Commonwealth’s Office determined that organizers for the anti-cannabis proposal had turned in enough valid signatures to put the measure before voters, a marijuana reform advocate filed an objection with the State Ballot Law Commission claiming that various signatures were not genuine, obtained through fraudulent means or were not “signed substantially as registered.”
The body rejected the challenge to the legal marijuana rollback measure, however, clearing it to go before voters to decide.
In June, the campaign behind the anti-legalization ballot measure fired a signature gatherer it says was shown appearing to engage in “wholly unacceptable” conduct in a recent video.
As Marijuana Moment reported, a man petitioning for the Massachusetts initiative as well as a similar anti-cannabis proposal in Maine was depicted in recent social media posts seeming to argue that voters who support legal marijuana access should sign the petitions in order to advance or protect reform.
The campaign later said it has “zero tolerance for any circulation tactics that would mislead petition signers.”
“The identified canvasser was immediately terminated, in coordination with our vendor, upon being made aware of the alleged conduct,” the group said. “The conduct apparent in the video would be wholly unacceptable and does not reflect how this campaign operates. We demand honesty, transparency and professionalism from everyone associated with our effort.”
A video posted to Reddit of the signature gatherer shows the man collecting signatures outside a retail store in Massachusetts next to a sign that says “keep cannabis legal.”
When confronted by a marijuana reform supporter who recorded the petitioner’s interactions with voters, he appeared to be trying to convince them that it is important to qualify the anti-cannabis measure for the ballot in order to then defeat it.
“This is what we’re fighting against right here. That’s why we vote no,” he said. “If we can get this to the ballot right here, we vote no.”
The person who captured the video pointed out that Massachusetts voters already approved marijuana legalization years ago, and that the only way it could be imminently repealed is if the new ballot measure qualified for the November election. If the initiative does not get enough signatures to go before voters, the state’s laws will remain the same.
“It’s my job,” the petitioner insisted, however. “I know what I’m talking about.”
“It’s a group of rich folks from out of state that want to basically take marijuana to when it was a medical marijuana card,” he said. “We don’t want that to happen.”
The same man also appeared to also be gathering signatures for a separate measure in Maine that would similarly repeal laws allowing regulated adult-use marijuana sales and home cultivation rights for adults while keeping possession legal and adding new testing requirements for medical cannabis.
A staffer for the prohibitionist organization Smart Approaches to Marijuana (SAM), whose affiliated group SAM Action is largely funding the anti-cannabis ballot campaigns in both states, declined to comment about the petitioner’s conduct when reached by Marijuana Moment.
The campaigns have previously been accused of misleading petitioning tactics.
In Massachusetts, some voters reported that the campaign used fake cover letters for other ballot measures on unrelated issues like affordable housing and same-day voter registration during the first round of petitioning. Legal cannabis supporters filed an earlier formal complaint about the prohibitionist effort’s tactics, but the State Ballot Law Commission rejected the challenge.
The measure also faced a legal challenge from cannabis industry operatives who argued it contains “impermissibly unrelated subjects,” and that the state attorney general’s official summary is “misleading and deficient.” The state Supreme Judicial Court heard oral arguments on the litigation challenging the anti-marijuana initiative but it ultimately ruled against the lawsuit.
The governor of Massachusetts last week filed legislation proposing to increase military veterans’ access to medical marijuana by allowing them to receive patient cards without having to get a doctor’s recommendation.
