Cannabis contains a seemingly unique class of chemicals, the cannabinoids, of which more than 60 have been described, but only a few are psychoactive. Cannabinoids are produced in specialized epidermal glands, which differ notably in distribution on different organs of the plant (high concentrations occur on the upper surface of the young leaves and young twigs, on the tepals, stamens, and especially on the perigonal bract). Given this distribution, the glands would seem to be protective of young and reproductive above-ground tissues (the roots lack glands). Two classes of epidermal glands occur—stalked and sessile (Fig. 8), but in either case the glandular cells are covered by a sheath under which resin is accumulated, until the sheath ruptures, releasing resin on the surface. The resin is a sticky mixture of cannabinoids and a variety of terpenes. The characteristic odor of the plant is due to the abundant terpenes, which are not psychoactive. The more important cannabinoids are shown in Fig. 9. In the plant the cannabinoids exist predominantly in the form of carboxylic acids, which decarboxylate with time or when heated. Delta-9-tetrahydrocannabinol (D9-THC, or simply THC) is the predominant psychoactive component. Other THC isomers also occur, particularly D8-THC, which is also psychoactive. Technically, the euphoric psychological effects of THC are best described by the word psychotomimetic. Cannabidiol (CBD) is the chief non-psychotomimetic cannabinoid. A THC concentration in marijuana of approximately 0.9% has been suggested as a practical minimum level to achieve the (illegal) intoxicant effect, but CBD (the predominant cannabinoid of fiber and oilseed varieties) antagonizes (i.e. reduces) the effects of THC (Grotenhermen and Karus 1998). Concentrations of 0.3% to 0.9% are considered to have “only a small drug potential” (Grotenhermen and Karus 1998). Some cannabinoid races have been described, notably containing cannabichromene (particularly in high-THC forms) and cannabigerol monomethyl ether (in some Asian strains). The biosynthetic pathways of the cannabinoids are not yet satisfactorily elucidated, although the scheme shown in Fig. 10 is commonly accepted. At least in some strains, THC is derived from cannabigerol, while in others it may be derived from CBD. CBN and D8-THC are considered to be degradation products or analytical artifacts (Pate 1998a).
CBC is another lesser-known yet still crucial cannabinoid in marijuana, especially from a therapeutic perspective. While bereft of the psychoactive quality of THC (and to a lesser extent THCV), CBC is gaining popularity as an anxiety reducer. While research on cannabichromene lags behind others, there’s good reason to continue looking into its potential as a medicine.
The Food and Drug Administration (FDA) does not consider CBD or products that contain CBD to be dietary supplements. This is because CBD has been studied and approved for use as a new drug to treat epilepsy, which means it is outside the definition of a dietary supplement.5 There may be products available that are marked as dietary supplements, however the amount of cannabidiol they claim to contain may not be accurate.
"Production differences depend on whether the cannabis plant is grown for fiber/oilseed or for medicinal/recreational uses. These differences involve the varieties being grown, the methods used to grow them, and the timing of their harvest (see discussion in 'Hemp' and 'Marijuana,' below). Concerns about cross-pollination among the different varieties are critical. All cannabis plants are open, wind and/or insect pollinated, and thus cross-pollination is possible.
Some jurisdictions use free voluntary treatment programs and/or mandatory treatment programs for frequent known users. Simple possession can carry long prison terms in some countries, particularly in East Asia, where the sale of cannabis may lead to a sentence of life in prison or even execution. Political parties, non-profit organizations, and causes based on the legalization of medical cannabis and/or legalizing the plant entirely (with some restrictions) have emerged in such countries as China and Thailand.
James Joliat, a 35-year-old video producer in Denver, has long experienced muscle and joint pain—mostly related to sports injuries. He says he started looking at natural remedies as an alternative to the prescription patches and pills his doctor recommended. After experimenting with homemade rubs infused with plant compounds—stuff like arnica and turmeric—he eventually stumbled onto topical cannabidiol (CBD) rubs.
Anything that is natural is abundant , there are many Natural cures on this planet. There is no money in Free, there is no money in none research. There is money in man made things. If we knew the cure for all the ailments and knew we could just grow them. Well that would put a lot of Professions out of business along with chemical companies just to name a few. There would be a lot less wealthy, rich people. No one wants to give up the good life. That’s why the world is the way it is UNFAIR. The few make sure it stays that way. Good luck my Fellow Americans… Keep up the good fight ..
While research into the effects of CBD on specific conditions is important, a broader perspective on the relationship between CBD and the human body is necessary to understand how this unique compound works. Interestingly, many of the conditions that are supposedly helped by CBD have no well-understood cause, from acne to Alzheimer’s disease. However, one of the few common denominators between these conditions is the involvement of the endocannabinoid system (ECS) in their causes.
