The LDS Political Coalition in Idaho

Last verified: April 2026

The Demographic Reality

You cannot understand Idaho cannabis policy without understanding that roughly 26.4% of Idahoans are members of The Church of Jesus Christ of Latter-day Saints, the highest non-Utah percentage in the United States. This is the demographic and political ground on which Idaho prohibition rests.

The LDS Geography

LDS concentration is highly regional. The southeastern quadrant of the state — the Snake River Plain east of Boise — is the heart of the Idaho church:

The Mormon Corridor

The corridor from Idaho Falls south through Pocatello, Burley, and into Utah's Cache and Box Elder Counties is sometimes called "the Mormon Corridor" — the demographic spine of the Intermountain West LDS population.

The Word of Wisdom

LDS opposition to recreational drug use rests on the Word of Wisdom, a revelation recorded in Doctrine and Covenants Section 89 in 1833. Originally received as advice and elevated to commandment status in the early 20th century, it counsels against tobacco, alcohol, "hot drinks" (interpreted as coffee and tea), and "harmful or addictive substances."

Faithful members in good standing — those who hold a temple recommend — must abstain. Cannabis is not specifically named in D&C 89 but has been treated by 20th- and 21st-century church leadership as falling within the scope of the prohibition.

Official Church Positions

The LDS Church has issued formal positions on cannabis policy three times in the past decade:

1. 2016: opposed Arizona Proposition 205 (adult-use legalization, defeated).
2. 2018: opposed Utah Proposition 2 (medical), then negotiated and supported the legislative replacement known as the "Utah Compromise" — a tightly regulated medical program with no smokable flower at retail (later relaxed) and pharmacist involvement.
3. 2020 onward: opposed any further recreational legalization, including Arizona Prop 207 (passed despite opposition).

The Idaho-specific posture has been to oppose any cannabis ballot initiative or legislative reform, including narrow medical bills. The church has not publicly endorsed an Idaho version of the Utah Compromise, and Idaho legislators close to the church have explicitly rejected one.

Why the Utah Compromise Didn't Translate to Idaho

1. No initiative pressure in Idaho. The Utah Compromise was negotiated because Prop 2 was about to pass; the church chose engagement over defeat. In Idaho, no initiative has qualified for the ballot, so the church faces no comparable forcing event.
2. Different legislative culture. Utah's legislature has institutional reform machinery and a tradition of brokered compromise. Idaho's legislature, dominated by the Idaho Freedom Foundation wing of the GOP, treats compromise as ideological surrender.
3. Different church-state interface. Utah's lawmakers are majority LDS and the state operates in close communication with church headquarters. Idaho's LDS legislators are a powerful caucus but not a majority, and Idaho's prohibition coalition includes evangelical and libertarian-prohibitionist factions whose interests are not identical to LDS interests.

Idaho LDS Legislators

Several of the most influential Idaho prohibitionist legislators are LDS, including Sen. C. Scott Grow (R-Eagle), the sponsor of HJR 4 (the constitutional cannabis-prohibition entrenchment amendment). The LDS legislative caucus is informal but cohesive; on cannabis votes it has historically held nearly 100% NO.

The "Mormon Belt" Comparative Frame

The Bonneville County Surprise

One of the most surprising data points in modern Idaho cannabis politics: Bonneville County (Idaho Falls, ~50% LDS) voted NO on HJR 4. The political class anticipated YES votes from LDS-belt counties; the actual ballot result showed that even in heavily-LDS communities, voters were not willing to constitutionally entrench cannabis prohibition. This suggests the LDS coalition's anti-cannabis power is real but not absolute. See HJR 4 page.
