Cannabis Prohibition Is Facing a Public Opinion Problem as Anti-Legalization Groups Push to Roll Back Marijuana Laws
For more than a decade, the political debate over marijuana has largely moved in one direction: toward legalization, regulation and decriminalization. But in 2026, a small group of prohibition advocates is working to push the conversation backward, seeking to roll back marijuana laws in states where voters have already embraced legal cannabis.
The effort is running into a significant obstacle, the push to recriminalize marijuana is running to voter reality…and voting can ensure it doesn’t change.
According to a January 2026 Pew Research Center survey, 55% of American adults said marijuana should be legal for both medical and recreational use, while another 33% said it should be legal for medical use only. Just 11% said marijuana should not be legal at all.

This does not mean Americans agree on everything involving cannabis. Concerns about youth use, impaired driving, high-potency products, public consumption and regulation remain part of the national debate. But the polling makes one thing clear: outright marijuana prohibition is no longer where most Americans stand.
And yet, organized efforts to reverse legalization are emerging.
One of the most visible organizations in the prohibition movement is Smart Approaches to Marijuana, or SAM. The organization describes itself as opposing both marijuana legalization and criminalization, while advocating prevention, treatment and tighter restrictions on the commercial cannabis industry. SAM currently opposes federal legislation which would end federal marijuana prohibition.
At the state level, Massachusetts has become an important test case. A 2026 ballot initiative seeks to repeal portions of the state’s voter-approved marijuana legalization framework, including provisions involving home cultivation and the regulated adult-use market. Massachusetts voters approved legalization in 2016. Polling cited by NORML found 55% of respondents opposed or were likely to oppose the repeal proposal, compared with 33% who supported it.
Older Americans are generally less supportive of full recreational legalization than younger adults. Pew’s 2026 survey found that 63% of adults ages 18 to 29 supported legal marijuana for both medical and recreational use, compared with 51% of those ages 50 to 64 and 43% of those 65 and older. Still, even among the oldest group, only 12% said marijuana should not be legal at all.
That distinction matters. It is fair to describe some prominent figures in the modern prohibition movement as older white men, but demographics alone do not establish why someone holds a particular policy position. The more important story is the gap between organized opposition and the broader public’s increasingly permissive view of marijuana.
There is also a changing federal landscape. In 2026, the Justice Department and DEA moved FDA-approved marijuana products and state-licensed medical marijuana products into Schedule III, while beginning a new administrative process to consider broader rescheduling of marijuana. Federal prohibition has therefore not disappeared, but the government’s approach is no longer simply a question of whether marijuana should be treated like the most restricted controlled substances.

The political fight over cannabis is consequently entering a new phase. The question is no longer simply whether marijuana should be legal. It is increasingly about how legal cannabis should be regulated, taxed and controlled—and whether voters who approved legalization should have those decisions reversed.
For prohibition advocates, this creates a difficult political environment. They may continue to argue legalization has produced unacceptable consequences. But any effort to make marijuana illegal again must contend with decades of changing public opinion and a country in which a large majority now supports at least some form of legal marijuana.
The marijuana debate isn’t disappearing. It is changing—and the fight over whether America moves forward or backward on cannabis policy may increasingly be decided by how voters weigh regulation, public health, personal freedom and the consequences of prohibition itself.
