Idaho
TLDR
Idaho is the most restrictive state in the nation for cannabis and hemp. It enforces a 0.0% THC zero-tolerance rule — not 0.3%, but absolute zero for all isomers and analogs. No medical, no recreational, no decriminalization. CBD is legal only if completely THC-free. Two competing November 2026 ballot measures create a critical juncture: medical legalization vs. a constitutional amendment that could permanently block voter-initiated cannabis policy.

How This Connects to Our Policy
Extreme prohibition state. ACFA Section 1 (Federal Hemp Protections) and TTSA Section 1 (Science-Based Standards) challenge blanket zero-tolerance bans. Idaho demonstrates the endgame of prohibition that OPS policy advocacy seeks to prevent nationwide.
