The hemp derives from CBD (Cannabidiol) oil. Some people are confused marijuana with hemp but hemp is a very different plant. Marijuana and hemp that share the same scientific name, but not the same, read this post here.
Marijuana is mainly cultivated for recreational and medical use for its psychoactive ingredient, a chemical compound called tetrahydrocannabinol or THC. The weed contains THC as well as CBD.
Hemp only contains a drop of THC, less than 0.3% relative to the heavy 5-35% pot. CBD is the key cannabinoid in hemp, but there are more than 100 other cannabinoids in hemp, as well as compounds that create tastes and scents called terpenes (e.g. citrus door of oranges, unusual fragrance of pine trees, or pleasant smell of lavender).
Hemp has been cultivated for thousands of years for food, clothing, fibre, and fuel. This is one of the oldest domesticated cultivations in the world. Hemp was a vitally significant crop in the US in the early days. Colonial farmers cultivated hemp during the 1700s mainly because of its strong fibre.
Hemp production however came to a sharp halt when the 1937 Cannabis Tax Act was passed. Mainstream views towards cannabis began to turn to the negative. Hemp has been the “evil weed,” as it contains the same genes as marijuana, although it does not contain the concentrated THC of marijuana.
Throughout the years, many have suggested that the real reason for the anti-cannabis movement was boiled down to the fear that hemp could become a low-cost paper pulp substitute. Throughout the wood and newspaper industry, American industrialist William Randolph Hearst and the DuPont family had big investments. They launched a smear campaign to disrupt the lucrative hemp market for fear of hemp rising undermining their income. Yet it became clear years later that hemp does not contain a sufficiently high concentration of cellulose to be an efficient paper substitute.
Eighty long years later, following the passage of the 2018 Farm Bill, hemp finally regained its legal status in the US. Hemp, classified as cannabis with less than 0.3 per cent THC, is exempt from the controlled substances in Schedule I. Hemp products are legal provided they come from approved hemp growers. It has started research by more and more universities and hospitals. Americans can legally use the CBD now. It can be purchased and delivered directly to all 50 states.
