On your 2026 ballot
3 statewide measures are certified for Idaho's 2026 ballots so far.
HJR 4Constitutional amendment · Drug policy · Nov 3, 2026
This amendment would provide that only the state legislature has the authority to legalize marijuana, narcotics, or other psychoactive substances. This would prevent legalization through citizen-initiated ballot measures.
A yes vote means: Gives the legislature sole authority to legalize marijuana, narcotics, or other psychoactive substances.
A no vote means: Keeps current law, under which citizen initiatives can also address these substances.
HJR 6Constitutional amendment · Language · Nov 3, 2026
This amendment would add language to the Idaho Constitution designating English as the official language of the state.
A yes vote means: Designates English as Idaho's official state language in the constitution.
A no vote means: Leaves the constitution without an official language designation.
Official State Gun QuestionBallot measure · State symbols · Nov 3, 2026
This non-binding advisory question asks voters to choose Idaho's official state gun from six historic firearm options. The legislature would still need to pass a separate law to adopt the winning choice.
A yes vote means: Selects one of six listed firearms as your preference for Idaho's official state gun.
A no vote means: There is no yes/no option; the result only advises the legislature and does not change the law by itself.
