CBD oil is most readily available as a tincture. This can be taken by applying a few drops under your tongue, holding in your mouth for a few moments so it can be absorbed, before swallowing. It can also be added to water or smoothies. A spray form is available (simply spritz under your tongue), as are capsules, gummies, creams that can be applied topically, and e-liquid for vape pens.
CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
Cutting-edge science has shown that the endocannabinoid system is dysregulated in nearly all pathological conditions. Thus, it stands to reason that “modulating endocannabinoid system activity may have therapeutic potential in almost all diseases affecting humans,” as Pal Pacher and George Kunos, scientists with the U.S. National Institutes of Health (NIH), suggested in a 2014 publication.
“Marijuana and industrial hemp are different varieties of the same plant species, Cannabis sativa L. Marijuana typically contains 3 to 15 percent THC on a dry-weight basis, while industrial hemp contains less than 1 percent (Blade, 1998; Vantreese, 1998). Most developed countries that permit hemp cultivation require use of varieties with less than 0.3 percent THC. However, the two varieties are indistinguishable by appearance. DeMeijer et al. (1992), in a study of 97 Cannabis strains, concluded that short of chemical analysis of the THC content, there was no way to distinguish between marijuana and hemp varieties.” http://www.ers.usda.gov/media/328202/ages001eb_1_.pdf
In terms of how CBD is extracted from the cannabis plant, there a few different techniques that can be used. The most popular used to be by running harsh chemicals like butane (lighter fluid) or hexane over the raw plant material, but people quickly found out that this resulted in trace amounts of carcinogenic compounds (like formaldehyde) being left over in the end product. Not good.
There has been a fair amount of confusion surrounding the legality of CBD oil. But while the vast majority of cannabinoids are controlled substances under the Misuse of Drugs Act, rest assured that CBD oil is legal across the UK for medicinal purposes, provided it has been derived from an industrial hemp strain that is EU-approved. These strains contain very little to no THC (the psychoactive cannabinoid).
There's also the question of CBD's legality – something that's a lot grayer than the black-and-white picture most companies paint. The U.S. Drug Enforcement Administration considers CBD, like all cannabinoids, a schedule 1 drug. That means it's just as illegal as heroin and ecstasy. Meanwhile, hemp – a variety of the cannabis plant regulated by the U.S. Department of Agriculture – is legal , so long as its THC content is negligibly low. But because the agriculture department doesn't test for CBD – only THC – in hemp, more companies are getting away with selling products they say contain CBD, says Sara Jane Ward, an assistant professor of pharmacology at the Temple University Lewis Katz School of Medicine who's been studying CBD in rodent models for more than 10 years. Needless to say, the legality of CBD is "very confusing and very gray," she says.
The CBD oil derived from cannabis plant is ideal for treating children and adults with epileptic/seizure disorders. This is because of low content of THC which is the main compound responsible for giving pot smokers a high when they take marijuana. In view of the curative powers of CBD oil several states within United States are legalizing its possession among people that are not related to its research. CBD rich oil is also used as a chief ingredient in vaping oil for use in e-cigarettes which can gradually reduce smoking as it does not have the ill effects of regular nicotine rich tobacco smoke that destroys lungs over a period of time.
And, if you do luck out and get a tincture truly containing CBD, you'll likely dish out $200 or so to take 10 to 40 milligrams daily. Since research participants take closer to 1,000 milligrams a day, it's hard to imagine a benefit without drinking the whole (expensive, calorie-dense) bottle, Tishler says. "Most people will adjust their doses based on what they're comfortable spending," Asquith says.
