The downsides of graphene are its dwindling sources and costly process to mine and import from rural areas in China and India. Hemp, however, can be grown in almost any terrain or country, and produces hemp bast, the key material used to replace graphene, as a waste byproduct of hemp processing. According to Mitlin’s research, hemp processing is 1,000 times cheaper than graphene processing.
Selective breeding of cannabis plants has expanded and diversified as commercial and therapeutic markets develop. Some growers in the U.S. succeeded in lowering the proportion of CBD-to-THC to accommodate customers who preferred varietals that were more mind-altering due to the higher THC and lower CBD content. Hemp is classified as any part of the cannabis plant containing no more than 0.3% THC in dry weight form (not liquid or extracted form).
Cannabis, also referred to as marijuana, has been an integral part of human civilizations for millennia. Both as a medicine and as a recreational substance, cannabis is the most popular illicit drug in the world. Today, the legal landscape that has prohibited marijuana for much of the twentieth century is giving way to decriminalization and full legalization. Legal, commercial cannabis businesses are already making an enormous economic impact.
Wild North American hemp is derived mostly from escaped European cultivated hemp imported in past centuries, perhaps especially from a revival of cultivation during World War II. Wild Canadian hemp is concentrated along the St. Lawrence and lower Great Lakes, where considerable cultivation occurred in the 1800s. In the US, wild hemp is best established in the American Midwest and Northeast, where hemp was grown historically in large amounts. Decades of eradication have exterminated many of the naturalized populations in North America. In the US, wild plants are rather contemptuously called “ditch weed” by law enforcement personnel. However, the attempts to destroy the wild populations are short-sighted, because they are a natural genetic reservoir, mostly low in THC. Wild North American plants have undergone many generations of natural adaptation to local conditions of climate, soil and pests, and accordingly it is safe to conclude that they harbor genes that are invaluable for the improvement of hemp cultivars. We have encountered exceptionally vigorous wild Canadian plants (Fig. 52), and grown wild plants from Europe (Fig. 53) which could prove valuable. Indeed, studies are in progress in Ontario to evaluate the agronomic usefulness of wild North American hemp. Nevertheless, present policies in North America require the eradication of wild hemp wherever encountered. In Europe and Asia, there is little concern about wild hemp, which remains a valuable resource.
Cannabis use for medicinal purposes dates back at least 3,000 years.[1-5] It was introduced into Western medicine in 1839 by W.B. O’Shaughnessy, a surgeon who learned of its medicinal properties while working in India for the British East India Company. Its use was promoted for reported analgesic, sedative, anti-inflammatory, antispasmodic, and anticonvulsant effects.
Hemp is the fiber and seed part of the Cannabis Sativa L. plant, opposed to the flower part of the plant which is “legally considered” marijuana. The fiber and seeds are incredible valuable and is why hemp is often called a “cash crop”. Hemp is a very hearty plant and grows very quickly in very diverse soil conditions. Cultivation of hemp for industrial purposes has been done by many civilizations for over 12,000 years. Industrial hemp was the desired fiber used to manufacture rope, canvas, paper, and clothing until alternative textiles and synthetics for these purposes were discovered. Although China has been the largest hemp producer over the years, other countries such as Australia and Canada are catching up. It has been illegal for anyone to grow hemp in the United States as hemp is illegal under the marijuana prohibition act but Colorado has changed the laws and paved the way for industrial hemp production again in the United States(see hemp history). Now hemp oils, hemp plastics, hemp building materials and many hemp fiber products can be seen and purchased on the market. Hemp is truly an amazing plant with the potential to help “green up” many industries.
There are new CBD companies coming online every week – these span the range from truly awful to really great. So how to choose the best? The quality of the CBD oil itself is obviously the most important factor – and many companies do take the quality of their products seriously. To reward those companies, we gave more weight to the quality of the product than any other category.
Probably indigenous to temperate Asia, C. sativa is the most widely cited example of a “camp follower.” It was pre-adapted to thrive in the manured soils around man’s early settlements, which quickly led to its domestication (Schultes 1970). Hemp was harvested by the Chinese 8500 years ago (Schultes and Hofmann 1980). For most of its history, C. sativa was most valued as a fiber source, considerably less so as an intoxicant, and only to a limited extent as an oilseed crop. Hemp is one of the oldest sources of textile fiber, with extant remains of hempen cloth trailing back 6 millennia. Hemp grown for fiber was introduced to western Asia and Egypt, and subsequently to Europe somewhere between 1000 and 2000 BCE. Cultivation in Europe became widespread after 500 ce. The crop was first brought to South America in 1545, in Chile, and to North America in Port Royal, Acadia in 1606. The hemp industry flourished in Kentucky, Missouri, and Illinois between 1840 and 1860 because of the strong demand for sailcloth and cordage (Ehrensing 1998). From the end of the Civil War until 1912, virtually all hemp in the US was produced in Kentucky. During World War I, some hemp cultivation occurred in several states, including Kentucky, Wisconsin, California, North Dakota, South Dakota, Minnesota, Indiana, Illinois, Ohio, Michigan, Kansas, and Iowa (Ehrensing 1998). The second world war led to a brief revival of hemp cultivation in the Midwest, as well as in Canada, because the war cut off supplies of fiber (substantial renewed cultivation also occurred in Germany for the same reason). Until the beginning of the 19th century, hemp was the leading cordage fiber. Until the middle of the 19th century, hemp rivaled flax as the chief textile fiber of vegetable origin, and indeed was described as “the king of fiber-bearing plants,—the standard by which all other fibers are measured” (Boyce 1900). Nevertheless, the Marihuana Tax Act applied in 1938 essentially ended hemp production in the United States, although a small hemp fiber industry continued in Wisconsin until 1958. Similarly in 1938 the cultivation of Cannabis became illegal in Canada under the Opium and Narcotics Act.
The main difference between the two is in its chemical composition, specifically in tetrahydrocannabinol (THC). THC is the chemical responsible marijuana’s psychological effects.An average batch of marijuana contains anywhere from 5-20% THC content. Some premium marijuana can have up to 25-30% THC. Hemp, on the other hand, has a max THC level of 0.3%, essentially making it impossible to feel any psychoactive effect or get a “high”. This threshold is heavily regulated in other countries that have legalized hemp.Hemp also has high cannabidiol (CBD) content that acts as THC’s antagonist, essentially making the minimal amount of THC useless.
Over the ages, countless innovations have attempted to improve on the basic experience of inhaling the smoke of combusted cannabis. As a result, there are numerous ways to smoke marijuana. The rolling technique is at the root of joints, blunts, and spliffs. On the other hand, glassware and other devices are essential for smoking weed out of a pipe, bong, or bubbler.
I have digenerative disc disease/4 bulgin discs was taking 9---10mg hydrocodones a day... i started with 3 drops of 300mg and within 5 mins started feeling better than i have theses last 6 years or so... not only that, the inflamation has decrease substantially, i wake up with energy and have begun to work out again... if im making it seem like a miracle drug... its because it is... so the first week i took 3 drops twice a day... now 3 weeks in... im taking about 5 drops 3 times a day and zero pain pills... for the first time in years i have taken control of my life agin... not depending on doctor scripts/bills etc....
