"Certificate of registration" means the certificate issued by the department attesting that the applicant is registered to process hemp.

"Decarboxylated" means the completion of the chemical reaction that converts delta-9 tetrahydrocannabinol's acids (THCA) into delta-9-tetrahydrocannabinol. The decarboxylated value may be calculated using a conversion formula that sums delta-9-tetrahydrocannabinol and eighty-seven and seven tenths (87.7) per cent of THCA.

"Delta-9 tetrahydrocannabinol" or "THC" means the primary psychoactive component of cannabis.

"Department" means the department of health.

"Director" means the director of health.

"Dry weight basis" refers to a method of determining the percentage of a chemical in a substance after removing the moisture from the substance.

"Enclosed indoor facility" means a permanent, stationary structure with a solid floor, rigid exterior walls that encircle the entire structure on all sides, and a roof that protects the entire interior area from the elements of weather. Nothing in this definition shall be construed to relieve the registered applicant from the applicant's duty to comply with all applicable building codes and regulations.

"FDA" means the United States Food and Drug Administration.

"Hemp" means Cannabis sativa L. and any part of that plant, whether growing or not, including the seeds thereof and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, with a delta-9-tetrahydrocannabinol concentration of not more than 0.3 per cent on a dry weight basis, as measured post-decarboxylation or by other similarly reliable methods.

"Hemp processor" means a person processing hemp to manufacture a hemp product.

"Hemp product" means a product that:
(1) Contains naturally occurring cannabinoids, compounds, concentrates, extracts, isolates, resins or derivatives from processed hemp;
(2) Does not include any living hemp plants, viable seeds, leaf materials, or floral materials;
(3) Has a delta-9-tetrahydrocannabinol concentration of not more than 0.3 per cent, as measured post-decarboxylation, or other similarly reliable methods;
(4) Is intended to be consumed orally to supplement the human or animal diet; and
(5) Is in the form of a tablet, capsule, powder, softgel, gelcap, or liquid form (e.g. hemp oil) to be used by the consumer to infuse edible items at home for personal use or for topical application to the skin or hair.
For purposes of this chapter, a hemp product shall be considered as intended for oral ingestion in liquid form only if it is formulated in a fluid carrier and it is intended for ingestion in daily quantities measured in drops or similar small units of measure per labeled directions for use.

"Manufacture" means to compound, blend, extract, infuse, or otherwise make or prepare a hemp product, but does not include planting, growing, harvesting, drying, curing, grading, or trimming a hemp plant or part of a hemp plant.

"Person" means an individual, firm, corporation, partnership, association, or any form of business or legal entity.

"Processing" means making a transformative change to the hemp plant following harvest by converting an agricultural commodity into a hemp product.

"Synthetic cannabinoid" means a cannabinoid that is:
(1) Produced artificially, whether from chemicals or from recombinant biological agents including but not limited to yeast and algae; and
(2) Not derived from the genus cannabis, including biosynthetic cannabinoids.
