Strains of Cannabis sativa L. cultivated for its tough bast fiber and edible seeds and oil; with a minimal level of delta-9-tetrahydrocannabinol / THC. Used industrially to develop products such as clothing fiber, paper, skincare products and therapeutic mixtures. Cultivated hemp is often distinguished from cannabis by possessing very low levels of psychoactive substance THC. The flowering portions of the hemp variety may be used to extract CBD. Hemp is separated into two species, the tall loosely branched (c. Sativa) and the low-growing densely branched (C. indica)
The Controlled Substances Act does not define hemp, per se. Its definition of marijuana includes all parts of the Cannabis sativa L. plant and the seeds and resin extracted from any part of such plant; it exempts all marijuana stalk, fiber, and sterilized seeds (and preparations made from them).
The 2018 Farm Bill descheduled Hemp / CBD having less than 0.3% THC by dry weight and states these products must not be used as supplements or foods, nor can it be used to treat a medical condition.
