Question 1

Is Delta-8 legal in Idaho?

Accepted Answer

Idaho bans all forms of THC including hemp-derived delta-8. Idaho law defines any amount of THC as a controlled substance with no exemption for hemp-derived isomers.

Question 2

Can I buy CBD in Idaho?

Accepted Answer

CBD is legal in Idaho ONLY if it contains absolutely 0.0% THC. Products must be derived from mature hemp stalks or seeds and contain no THC whatsoever. HB 879 (2026, effective July 1, 2026) updated the state industrial hemp program (Idaho Code §22-1701 et seq.).

Question 3

What is the age limit for hemp products in Idaho?

Accepted Answer

Idaho has no statutory minimum age specific to hemp products; retailers commonly require 21+.

Question 4

Will hemp products be legal in Idaho after November 2026?

Accepted Answer

Section 781 of H.R. 5371 (Continuing Appropriations and Extensions Act, 2026, Pub. L. 119-37) — signed November 12, 2025, effective November 12, 2026 — redefines hemp with a 0.4 mg total-THC-per-container cap and excludes artificially derived cannabinoids. Idaho already applies a zero-THC controlled-substances definition independent of federal hemp law, so the federal rider has little practical effect; the state bans essentially all hemp-derived THC regardless of the 0.4 mg cap. Impact is low.
