Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid.[45] In strongly basic media and the presence of air, it is oxidized to a quinone.[46] Under acidic conditions it cyclizes to THC.[47] The synthesis of cannabidiol has been accomplished by several research groups.[48][49][50]
Cannabis Indica – The annual plant of the Cannabaceae family is considered a species of the genus Cannabis, but separate from Cannabis sativa, and originating in the Hindu Kush Mountains and suited for cultivation in temperate climates. Used to induce sleep, the plant is described as relatively short and conical with dense branches and short, broad leaves, while Cannabis sativa is tall with fewer branches and long, narrow leaves.
Cannabis, especially the cannabinoid CBD, has also demonstrated its abilities as a powerful anti-convulsant. This property is what accounts for cannabis’ ability to reduce the severity and frequency of seizures, especially for people with epilepsy. In the United States, epilepsy is the most widely adopted qualifying condition for medical cannabis use, especially for children.
State policymakers have taken action to address various policy issues — the definition of hemp, licensure of growers, regulation and certification of seeds, state-wide commissions and legal protection of growers. At least 41 states have passed legislation related to industrial hemp, such as defining hemp and removing barriers, and at least 39 states have allowed for hemp cultivation and production programs. Some states establishing these programs require a change in federal laws or a waiver from the DEA prior to implementation.
Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”

About half of the world market for hemp oil is currently used for food and food supplements (de Guzman 2001). For edible purposes, hempseed oil is extracted by cold pressing. Quality is improved by using only the first pressing, and minimizing the number of green seeds present. The oil varies in color from off-yellow to dark green. The taste is pleasantly nutty, sometimes with a touch of bitterness. Hemp oil is high in unsaturated fatty acids (of the order of 75%), which can easily oxidize, so it is unsuitable for frying or baking. The high degree of unsaturation is responsible for the extreme sensitivity to oxidative rancidity. The oil has a relatively short shelf life. It should be extracted under nitrogen (to prevent oxidation), protected from light by being kept in dark bottles, and from heat by refrigeration. Addition of anti-oxidants prolongs the longevity of the oil. Steam sterilization of the seeds, often required by law, allows air to penetrate and so stimulates rancidity. Accordingly, sterilized or roasted hemp seeds, and products made from hemp seed that have been subjected to cooking, should be fresh. The value of hemp oil from the point of view of the primary components is discussed below. In addition, it has been suggested that other components, including trace amounts of terpenes and cannabinoids, could have health benefits (Leizer et al. 2000). According to an ancient legend (Abel 1980), Buddha, the founder of Buddhism, survived a 6-year interval of asceticism by eating nothing but one hemp seed daily. This apocryphal story holds a germ of truth—hemp seed is astonishingly nutritional.
Hemp, (Cannabis sativa), also called industrial hemp, plant of the family Cannabaceae cultivated for its fibre (bast fibre) or its edible seeds. Hemp is sometimes confused with the cannabis plants that serve as sources of the drug marijuana and the drug preparation hashish. Although all three products—hemp, marijuana, and hashish—contain tetrahydrocannabinol (THC), a compound that produces psychoactive effects in humans, the variety of cannabis cultivated for hemp has only small amounts of THC relative to that grown for the production of marijuana or hashish.
Hemp rope was used in the age of sailing ships, though the rope had to be protected by tarring, since hemp rope has a propensity for breaking from rot, as the capillary effect of the rope-woven fibers tended to hold liquid at the interior, while seeming dry from the outside.[42] Tarring was a labor-intensive process, and earned sailors the nickname "Jack Tar". Hemp rope was phased out when Manila, which does not require tarring, became widely available. Manila is sometimes referred to as Manila hemp, but is not related to hemp; it is abacá, a species of banana.
CBD has been producing a whole lot of buzz in the health community of late – but perhaps not the kind of buzz you might expect from a cannabinoid. Since you’re reading this, you’ve probably heard of CBD and its many touted benefits. From chronic pain to mental health, CBD has the potential to alleviate an astonishing number of ailments. But like many, you might be fuzzy on the details. Consider this your primer on all things CBD.
Hemp allows farmers to build a livelihood from a crop that’s both good for the environment and the growers themselves. Hemp puts back nitrogen into the soil. Cotton, on the other hand, can deplete the land’s nutrients, especially if not rotated with other crops. Unlike cotton which produces shorter fibers, hemp, though brittle when dry, thrives when it’s wet, explains Derek Thomas, co-founder of Hemp Blue, a LA-based startup producing hemp-based jeans, jackets, and shirts. The long, wet fibers don’t break, but actually grow in strength, he says. Hemp’s longer, wet fibers have greater durability than cotton, which has short fibers that need to be spun and woven.
The environment in which hemp and marijuana are grown is strikingly different. Hemp is grown closely together (as close as 4 inches apart) and are typically grown in large multi-acre plots. It can also grow in variety of climates and its growth cycle is 108-120 days. Unlike hemp, marijuana requires a carefully controlled, warm, and humid atmostphere for proper growth. Its growth cycle only 60-90 days. Medical cannabis also cannot be grown too close to each other. They are typically grown 6 feet apart. If, somehow, marijuana grows among (or close to) a hemp field, the hemp’s pollen would immediateately ruin the marijuana crop, diluting marijuana’s psychoactivity.
A population-based case-control study of 611 lung cancer patients revealed that chronic low Cannabis exposure was not associated with an increased risk of lung cancer or other upper aerodigestive tract cancers and found no positive associations with any cancer type (oral, pharyngeal, laryngeal, lung, or esophagus) when adjusting for several confounders, including cigarette smoking.[7]
There are also other difficulties in researching the effects of cannabis. Many people who smoke cannabis also smoke tobacco.[265] This causes confounding factors, where questions arise as to whether the tobacco, the cannabis, or both that have caused a cancer. Another difficulty researchers have is in recruiting people who smoke cannabis into studies. Because cannabis is an illegal drug in many countries, people may be reluctant to take part in research, and if they do agree to take part, they may not say how much cannabis they actually smoke.[266]
Marijuana is the most popular illicit drug in the world, for no reason other than the fact that it produces a psychoactive chemical called tetrahydrocannabinol. Still, recreational marijuana use, which involves pursuing the euphoric sensations produced by cannabis consumption, is steadily becoming more and more legal, both in the United States and abroad.
“The week before we tried it, we had 64 seizures,” Penny told me, noting those were only the visible seizures, while unseen neurological events would likely push the number into the hundreds. “We administered hemp oil, and the next week we logged in 28 seizures. ... The very next week, her second week on the hemp oil, we logged none.” Penny paused and repeated herself, as though she could still only half believe the miracle: “None.”

The gateway effect may appear due to social factors involved in using any illegal drug. Because of the illegal status of cannabis, its consumers are likely to find themselves in situations allowing them to acquaint with individuals using or selling other illegal drugs.[256][257] Utilizing this argument some studies have shown that alcohol and tobacco may additionally be regarded as gateway drugs;[258] however, a more parsimonious explanation could be that cannabis is simply more readily available (and at an earlier age) than illegal hard drugs. In turn alcohol and tobacco are easier to obtain at an earlier point than is cannabis (though the reverse may be true in some areas), thus leading to the "gateway sequence" in those individuals since they are most likely to experiment with any drug offered.[249]
Breeding for low THC cultivars in Europe has been reviewed by Bócsa (1998), Bócsa and Karus (1998), and Virovets (1996). Some researchers have claimed to have produced essentially THC-free strains, although at present no commercial cultivar seems to be 100% free of THC. THC content has proven to be more easily reduced in monoecious than in dioecious varieties. It should be possible to select THC-free strains, and there has been speculation that genetic engineering could be helpful in this regard. As a strategic economic and political tactic, France has been attempting for several years to have the European Union (EU) adopt legislation forbidding the cultivation of industrial hemp cultivars with more than 0.1% THC, which would mean that primarily French varieties would have to be cultivated in Europe. However, the Canadian government has found that some French material has proven to be excessively high in THC.
Cannabinoids may also contribute to pain modulation through an anti-inflammatory mechanism; a CB2 effect with cannabinoids acting on mast cell receptors to attenuate the release of inflammatory agents, such as histamine and serotonin, and on keratinocytes to enhance the release of analgesic opioids has been described.[45-47] One study reported that the efficacy of synthetic CB1- and CB2-receptor agonists were comparable with the efficacy of morphine in a murine model of tumor pain.[48]
Did you get an answer for this? I have the exact same scenario. I'm treating my TN with Tegretol, and recently tried CBD. I think I took too much and there are some weird drug interactions with Tegretol and I felt quite stoned....was alone and talking to myself in my head thinking I was Einstein. It freaked me out a bit but I think I took too much. I'm trying lower doses again as recently my TN seems to be resisting the meds, although I have had a lot of emotional stress, which seems to be a trigger. Thanks!! Anna
