Kratom (Mitragyna speciosa) Verified 2026-05-23

Idaho has not enacted a Kratom Consumer Protection Act or a kratom ban. Kratom (Mitragyna speciosa) remains legal for sale and possession in Idaho with no statewide age, labeling, or purity standards beyond general consumer-protection law. Federally, kratom remains unscheduled by the DEA but has been the subject of FDA import alerts and warning letters; the FDA does not approve kratom for any therapeutic use. Local municipalities in Idaho may have enacted ordinances restricting sale; verify locally before retail operations.

Kava (Piper methysticum) Verified 2026-05-23

Kava (Piper methysticum) is legal for sale and consumption in Idaho with no statewide scheduling or sales restrictions. Kava bars (commercial kava-serving establishments) operate in many US states. The FDA issued a 2002 consumer advisory about potential hepatotoxicity associated with kava use; subsequent research has generally found risk concentrated in poor-quality preparations, but the advisory remains in place and informs the regulatory posture. Idaho may apply general dietary-supplement and food-safety rules to kava products.

CBD and hemp products Verified 2026-05-23

Idaho has historically imposed restrictions on CBD products beyond the federal Farm Bill floor. Specific restrictions vary: some states limit CBD to FDA-approved Epidiolex; others restrict CBD in food and beverage; others restrict hemp-derived intoxicating cannabinoids (Delta-8 THC, Delta-10 THC) more aggressively than the federal posture. Verify the current Idaho Department of Agriculture hemp-program rules and state Board of Pharmacy stance on CBD-in-food before retail operations.

Psilocybin and psychedelic compounds Verified 2026-05-23

Psilocybin and psilocin remain DEA Schedule I controlled substances federally and are prohibited under Idaho controlled-substance law. Sale, possession, and use carry criminal penalties under Idaho statute. Some US municipalities have decriminalized possession through local-priority resolutions (Denver, Oakland, Santa Cruz, Seattle, Detroit, and others) but municipal decriminalization does not change state or federal scheduling. Verify any Idaho city-level decriminalization status separately.

Age restrictions on supplement purchase Verified 2026-05-23

Federal law sets the nationwide minimum age for tobacco and nicotine products at 21 (Tobacco 21, 2019). Beyond tobacco/nicotine, US supplement age-restriction is patchwork: dietary supplements under DSHEA generally lack statutory minimum-purchase age at the federal level. Idaho does not impose a statewide minimum age for dietary supplement purchase beyond the federal tobacco/nicotine floor. Local municipalities may impose additional age restrictions on specific products (energy drinks, CBD, supplements with stimulant labels). Verify locally before retail operations.

Labeling and disclosure requirements Verified 2026-05-23

Dietary supplements sold in Idaho are subject to FDA labeling rules under the Dietary Supplement Health and Education Act (DSHEA, 1994), requiring Supplement Facts panel, ingredient list, "dietary supplement" identifier, manufacturer/packer/distributor name and address, and the FDA structure-function claim disclaimer where applicable. Idaho may impose additional state-specific labeling, testing, or licensing requirements for high-risk categories (kratom, CBD, kava, sports supplements). Verify current rules with the Idaho Department of Agriculture and Board of Pharmacy.
