What is industrial hemp?
As defined in s.94.55 (1) Wis. Stats. “industrial hemp” means the plant Cannabis sativa L., or any part of the plant including seeds, having a Delta-9-Tetrahydrocannabinol (THC) concentration of 0.3% or less. The statute includes the definition a substance, material, or product that is not designated as a controlled substance under the state Uniform Controlled Substances Act, or the federal Controlled Substances Act, or both.
Industrial hemp is classified as non-drug Cannabis sativa varieties, whose fruit is technically an achene, or a single-seeded fruit similar to a sunflower. Both the seed and hemp’s tall stalk provide significant carbohydrate feedstocks for a wide variety of industrial purposes that are used in several countries. The oil pressed from hempseed in particular, is a rich source of polyunsaturated omega-3 and omega-6 fatty acids, which are essential for human health. These same fatty acids in hempseed oil make it a fine drying oil that is used in the production of paints, varnishes, and other coating materials. Plastic flooring such as linoleum and similar materials have been made from hempseed oil, and other non-food uses of hempseed oil are similar to those of linseed oil (flaxseed oil).
