The Modern Timeline
Idaho criminalizes cannabis
Idaho enacts state-law cannabis prohibition — a decade before the federal Marijuana Tax Act. The 1927 statute criminalizes possession and sale of "Indian hemp" or "cannabis indica."
Federal Marijuana Tax Act
Federal alignment with Idaho's existing prohibition.
Idaho Uniform Controlled Substances Act
Title 37, Chapter 27 codified. Marijuana placed on Schedule I. Penalty tiers, paraphernalia, trafficking concepts codified largely as they exist today.
Tough-on-drugs mandatory minimums
Federal "tough on crime" wave produces Idaho's mandatory-minimum trafficking scheme at §37-2732B. The 1-pound trafficking trigger and 25-lb / 100-lb escalators date from this era.
Failed initiative attempts
Multiple medical-marijuana initiatives fail to qualify for the ballot under Idaho's 6%-in-18-of-35-districts geographic-distribution requirement.
HCR 23 — symbolic resolution
Non-binding "Compassionate Cannabis" resolution acknowledging pediatric epilepsy patients potentially benefiting from CBD.
Sen. Hartgen's SB 1146 vetoed
Narrow CBD-oil bill for pediatric epilepsy passes the legislature; Gov. Butch Otter vetoes.
Big Sky Scientific seizure
ISP seizes ~7,000 pounds of industrial hemp from a Big Sky Scientific tractor-trailer on I-84 near Boise. Federal litigation follows.
HB 126 hemp + HJR 4 entrenchment
HB 126 creates Idaho's 0.0% THC hemp program. HJR 4 places constitutional cannabis-prohibition entrenchment amendment on Nov 2022 ballot.
HJR 4 defeat at ballot box
⚠️ Voters reject the constitutional cannabis-prohibition amendment ~55% / 45%. The most significant Idaho cannabis political event since 1971.
SCR 110 + HB 124 fail
Senate symbolic-prohibition resolution passes; House psilocybin-therapy bill fails in committee.
Kind Idaho 2026 medical initiative
Active signature-gathering for November 2026 ballot. Open governor's race; federal rescheduling overhang.
The 1990s Mandatory-Minimum Era
The 1990s federal "tough on crime" wave produced Idaho's mandatory-minimum trafficking scheme codified at §37-2732B. The 1-pound trafficking trigger and the 25-lb / 100-lb escalators date from this era, as does the school-zone enhancement at §37-2739B. See trafficking page.
The 2002 Medical-Marijuana Ballot Rejection
A 2002 medical-marijuana proposal failed to qualify for the ballot. Subsequent legislative attempts in 2003–2008 received no committee hearings.
The 2010s — Initiative Attempts and HCR 23
The 2012, 2014, and 2018 initiative attempts (see failed initiatives) all failed to qualify. In 2014 the legislature adopted HCR 23, a non-binding "Compassionate Cannabis" resolution acknowledging the existence of pediatric epilepsy patients potentially benefiting from CBD. HCR 23 had no operative effect — it neither legalized CBD nor created a program — but it was the first Idaho legislative document to formally acknowledge therapeutic cannabis context.
2015 — Sen. Hartgen's CBD Oil Bill Veto
In 2015 the legislature passed SB 1146, a narrow CBD-oil bill for pediatric epilepsy. Gov. Butch Otter (R) vetoed it and instead issued an executive order creating a tightly limited "Expanded Access" trial through Idaho hospitals. The veto remains a touchstone in reform-side rhetoric.
2018 — Big Sky Scientific Seizure
January 2018: ISP seizes ~7,000 pounds of industrial hemp from a Big Sky Scientific tractor-trailer on I-84 near Boise. The federal litigation that follows produces the 9th Circuit decision (see page) and effectively forces Idaho to adopt some hemp law.
2021 — HB 126 Hemp + HJR 4 Entrenchment
A pivotal year:
- HB 126 (signed by Gov. Brad Little in April 2021) created Idaho's hemp program — at the 0.0% THC standard — finally ending Idaho's status as the only no-hemp state. See 0.0% standard.
- HJR 4, passed by the legislature the same session, placed the constitutional cannabis-prohibition entrenchment amendment on the November 2022 ballot.
2022 — HJR 4 Defeat at the Ballot Box
⚠️ November 8, 2022: voters reject HJR 4 ~55% / 45%. The most significant Idaho cannabis political event since 1971. See HJR 4 page.
2023–2024 — Stalemate and SCR 110
The 2023 and 2024 sessions saw no significant cannabis legislation pass:
- SCR 110 (2024) — non-binding Senate concurrent resolution reaffirming opposition to legalization.
- HB 124 (2024) — psilocybin-therapy bill; failed in House Health & Welfare.
2025 — Federal Rescheduling Overhang
⚠️ Through 2024–2025 the DEA's proposed rule to reschedule cannabis from Schedule I to Schedule III moved through administrative-law-judge proceedings, and various procedural complications and litigation extended timelines into 2026. As of April 2026 the federal-schedule outcome is not final. Idaho's statutory schedule is independent of federal action and would not change automatically.
2026 — The Current Stalemate
As of April 2026, Idaho has:
- No medical program.
- No decriminalization.
- 0.0% THC hemp standard.
- A pending Kind Idaho 2026 medical-cannabis initiative collecting signatures.
- An open governor's race with both major-party fields forming.
- A Republican legislative supermajority with no cannabis bill on the calendar.
The next inflection point will be either the Kind Idaho 2026 ballot qualification (or non-qualification) or a federal rescheduling decision that materially changes the legal-and-political ground.
