(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.

[Separate exclusion for FDA-approved CBD drugs with] "no more than one-tenth of one percent (0.1%) (w/w) residual tetrahydrocannabinols". [ISDA draft rule strawman 8/19/2026: hemp products are] "All inhalable and/or ingestible hemp products intended for human ingestion or inhalation"; [end products must have] "no detectable THC of any kind".
