Idaho Voters Preserve Ballot Route for Marijuana Legalization

Unofficial results published by the Idaho Secretary of State showed voters rejecting House Joint Resolution 4 in the November 3, 2026, general election, preserving citizens’ ability to pursue marijuana legalization or decriminalization through state statutes initiated by ballot petition. The statewide returns, updated November 4, 2026, recorded 471,288 no votes, or 66.27%, against 239,893 yes votes, or 33.73%. The amendment required 50% plus one vote to pass.

The ballot asked whether only the Idaho Legislature should have the power and authority to legalize the growing, producing, manufacturing, transporting, selling, delivering, dispensing, administering, prescribing, distributing, possessing or using of marijuana, narcotics or other psychoactive substances. A no vote retains citizens’ ability to initiate state statutes that would legalize or decriminalize those substances.

What the Amendment Would Have Changed

The resolution’s text proposed adding a second subsection to Section 26, Article III of the Idaho Constitution. It would have vested the listed legalization powers only in the Legislature, effective immediately upon voter adoption. The proposal therefore concerned who could change state law; it did not itself legalize or decriminalize cannabis.

HJR 4 originated with the Legislature’s State Affairs Committee rather than a citizen cannabis petition. Its legislative history records a 58-10 House adoption vote on March 5, 2025, with two members absent, followed by a 29-6 Senate adoption vote on March 11, 2025. The resolution directed that the question be submitted to voters at the next general election.

The Initiative Route Remains Demanding

Keeping that route available does not make ballot qualification automatic. Sponsors of a statewide initiative must collect signatures equal to 6% of the total registered voters at the last general election. The signatures must also meet a geographic requirement: distribution across at least 18 legislative districts, with signatures from at least 6% of registered voters in each district by the deadline.

Two cannabis proposals failed to join HJR 4 on the ballot. The Idaho Medical Cannabis Act and the Decriminalize Cannabis Now Initiative did not qualify after failing to submit the required number of valid signatures both statewide and in the required legislative districts.

Earlier efforts also fell short. The Idaho Medical Marijuana Initiative did not qualify in 2024. In 2022, both the Idaho Medical Marijuana Act of 2022 and the Personal Adult Marijuana Decriminalization Act failed to qualify. A separate initiative to establish a medical marijuana program for qualifying patients also failed to qualify in 2020.

That history defines the practical consequence of the vote. Idaho citizens retain the power to propose legalization or decriminalization statutes, but retaining the mechanism is different from securing a ballot place. For future cannabis sponsors, the central test is whether they can satisfy both the statewide signature total and the required geographic distribution.
