Illegal

As of November 12, 2026, HHC-P (Hexahydrocannabiphorol) is illegal to sell at retail in Idaho. HHC-P illegal: synthetic cannabinoid derivatives of similar structure are Idaho Schedule I (37-2705(d)(29)). Listed as schedule 1, effective 2021-04-16. Controlling source: Idaho Code 37-2705 -- Schedule I (subsection (d)(29): tetrahydrocannabinols and synthetic substances/derivatives/isomers with similar chemical structure).

HHC-P is a synthetic cannabinoid derivative with chemical structure similar to tetrahydrocannabinols, a Schedule I class under Idaho Code 37-2705(d)(29).

What the record says

Idaho Code 37-2705(d)(29) places in Schedule I tetrahydrocannabinols, synthetic equivalents of plant substances, and synthetic substances, derivatives and their isomers with similar chemical structure, and its examples include a dimethylheptyl hexahydrocannabinol (HU-243). HHC-P, the heptyl homolog of HHC made by hydrogenating converted THCP, is a synthetic substance with structure similar to the listed tetrahydrocannabinols, read the same way as HHC in the sibling rows. The industrial hemp exception covers only THC in industrial hemp, and Idaho has no lawful retail channel.

(u) "Marijuana" or "marihuana" means all parts of the plant of the genus Cannabis, regardless of species, and whether growing or not; the seeds thereof; the resin extracted from any part of such plant; and every compound, manufacture, salt, derivative, mixture, or preparation of such plant, its seeds or resin. It does not include: (1) Industrial hemp or hemp possessed, grown, transported, farmed, produced, processed, or possessed by any other entity engaged in hauling, transporting, delivering, or otherwise moving hemp in interstate or intrastate commerce pursuant to a license granted under the provisions of the 2014 farm bill, the 2018 farm bill, 7 CFR 990.1 et seq., or the approved state plan for the state of Idaho. “Industrial hemp” or "hemp" means the plant species Cannabis sativa L. and any part of that plant, including the seeds thereof and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, whether growing or not, with a measured total delta-9 tetrahydrocannabinol concentration of not more than three-tenths of one percent (0.3%) on a dry weight or volume basis that shall determine the total delta-9 tetrahydrocannabinol (THC) concentration, including both delta-9 tetrahydrocannabinol and delta-9 tetrahydrocannabinolic acid (THCA) evaluated by decarboxylation during analysis, or by measuring each compound and calculating the total percentage of delta-9 tetrahydrocannabinol if the THCA was decarboxylated, which must not exceed three-tenths of one percent (0.3%). (2) The mature stalks of the plant genus Cannabis unless the same are intermixed with prohibited parts thereof, fiber produced from the stalks, oil or cake made from the seeds or the achene of such plant, any other compound, manufacture, salt, derivative, mixture, or preparation of the mature stalks, except the resin extracted therefrom or where the same are intermixed with prohibited parts of such plant, fiber, oil, or cake, or the sterilized seed of such plant which is incapable of germination. Evidence that any plant material or the resin or any derivative thereof, regardless of form, that does not meet the definition of “industrial hemp” or "hemp" as provided in this section, or that is possessed without a license granted under the provisions of the 2014 farm bill, the 2018 farm bill, 7 CFR 990.1 et seq., or the approved state plan for the state of Idaho, contains any of the chemical substances classified as tetrahydrocannabinols shall create a presumption that such material is "marijuana" as defined and prohibited herein. "Marijuana" does not include drug product in finished dosage formulation that has been approved by the United States food and drug administration that contains: (i) cannabidiol (2-[1R-3-methyl-6R-(1-methylethenyl)-2-cyclohexen-1-yl]-5-pentyl-1,3-benzenediol), derived from cannabis and no more than one-tenth of one percent (0.1%) (w/w) residual tetrahydrocannabinols; or (ii) nabiximols. Additionally, Idaho Code 22-1705(4), added by 2026 House Bill 879 (Session Law Chapter 292, effective 7/1/2026): "Establishments offering hemp products intended for human ingestion or inhalation, excluding nonviable hulled hemp seed, hemp seed protein powder, or hemp seed oil, shall be subject to the provisions of this chapter. Such hemp products shall meet the criteria provided by sections 37-2701(u) and 37-2705(d)(29)(i), Idaho Code."
