Idaho

Medical cannabis is prohibited in Idaho. Severe criminal penalties may apply for possession, use, or trafficking.

Idaho maintains the strictest cannabis laws in the United States, with no medical cannabis program, no CBD-specific exemptions beyond federal hemp compliance (0.3% THC), and no decriminalization provisions. In 2025, Governor Brad Little signed H0007, creating a mandatory minimum $300 fine for possession of 3 ounces or less effective January 1, 2026, in addition to possible jail time. The legislature passed HJR 4 in March 2025 to prohibit citizens from using ballot initiatives to change cannabis or drug laws, reserving that power exclusively to the legislature. The Natural Medicine Alliance of Idaho is attempting to collect signatures for a medical cannabis ballot measure for November 2026, with an April 30, 2026 deadline. Idaho is one of the few states with no legal cannabis access of any kind.
