Hemp (Cannabis sativa), also known as industrial hemp, is a plant of the Cannabaceae family that is cultivated for its fiber or edible seeds. It is one of the fastest growing plants on Earth and was one of the first plants to be spun into usable fiber 50,000 years ago. Hemp can be refined into a variety of commercial items, such as paper, ropes, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food and animal feed. Hemp is a variety of the cannabis sativa plant and contains tetrahydrocannabinol (THC), but it is different from cannabis in terms of composition and use.
In the 1600s, King John IV placed renewed emphasis on the cultivation of hemp in order to recover the weakened Portuguese naval fleet after the Restoration of Independence. As mechanical technology evolved, the separation of the fiber from the core was achieved by shredding rollers and brush rollers, or by milling with a hammer. Hemp seeds have a high energy content and are a traditional staple food for poultry mixes due to their low cost. Hemp can be used to make a variety of items such as clothing, paper, animal feed, and textiles.
It can also be used for insulation due to its porous materiality which allows air and moisture penetration without losing any thermal properties. Hemp cultivation lasts approximately 100 days which is much faster than the average tree used for construction. Hemp seed oil has been evaluated for its effects on growth, body composition and meat quality parameters with no difference found with respect to the added oil. The Hemp Plan recently approved by the IDOA complies with changes made from the provisional rule to the final rule.
The product under study was an industrial hemp extract reconstituted in olive oil which mainly contained CBD together with low concentrations of other phytocannabinoids.
