CBD and THC are the main cannabinoids (among several) found in cannabis. The term “marijuana” is used for the recreational and medicinal use of products derived from flowers and leaves.
Hemp, or industrial hemp, is a botanical class of Cannabis sativa cultivars grown specifically for industrial or medicinal use. It has long been known for its more than 25,000 potential uses as a product thanks to its fibrous composition and versatile seeds.
Hemp can be used to make a wide range of products, and is among the fastest growing plants on Earth. It was also one of the first plants to be converted 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 (Cannabis sativa) is sometimes confused with cannabis plants that serve as sources of the drug marijuana and prepared hashish. Although all three products (hemp, marijuana and hashish) contain tetrahydrocannabinol (THC), a compound that produces psychoactive effects on humans, the cannabis strain cultivated for hemp contains only small amounts of THC compared to that grown for the production of marijuana or hashish.
Cannabis is one of the most cultivated plants in the world and the only widely abused drug cultivated within the borders of the United States. The main psychoactive (mind-altering) chemical in marijuana, responsible for most of the intoxicating effects people seek, is delta-9-tetrahydrocannabinol (THC). The chemical substance is found in the resin produced by leaves and buds, mainly from the female cannabis plant. The plant also contains more than 500 chemicals, including more than 100 compounds chemically related to THC, called cannabinoids. Hemp is grown in temperate areas as an annual crop from seed and can reach a height of up to 5 meters (16 feet).
In addition to the CO2 absorbed during its growth period, hemp is repeated during the creation of concrete.
Hemp InsulationHemp insulation is naturally lightweight and non-toxic, allowing for exposed installation in a variety of spaces, including floors, walls and ceilings. Completed nine years later, the buildings were discovered to be one of the most technologically advanced structures made of hemp-based material.
HydroponicsHydroponics simply means growing without soil, using a liquid solution that contains all the nutrients and minerals needed to produce a healthy plant. The porous material of hemp insulation allows air and moisture to penetrate, with an apparent density of up to 20% without losing any thermal properties.
Hemp for VictoryHemp for Victory, a short documentary produced by the United States Department of Agriculture during World War II. In order to recover the weakened Portuguese naval fleet after the Restoration of Independence in 1640, King John IV placed renewed emphasis on the cultivation of hemp.
HistoryBarber (199), however, argued that the spread of the name kannabis was due to its more historically recent use of plants, starting in the south, around Iran, while THC-free hemp varieties are older and prehistoric.
From the 1950s to the 1980s, the Soviet Union was the world's largest producer of hemp (3000 square kilometers (1200 square miles) in 1970). In the United Kingdom, the Department for Environment, Food and Rural Affairs treats hemp as an exclusively non-food crop, but with appropriate licenses and proof of a THC concentration lower than 0.3%, hemp seeds can be imported for planting or sale as a food or food ingredient.
