At present, we have the following classification of cannabinoids: endocannabinoids (produced naturally in the body, mainly from fatty acid precursors), phytocannabinoids (compounds that have a plant origin, with the cannabis plant being the best-studied source of phytocannabinoids though not the only one), and artificial cannabinoids (created while studying THC, to garner the benefits of marijuana without the recreational component).
If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $22 billion by 2022, per the Chicago-based research firm Brightfield Group.
Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43 percent had more CBD than indicated, while 26 percent had less, and some had unexpected THC.“There’s a 75 percent chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.
CBD hemp oil has a number of uses and comes in many forms including capsules, tinctures, sublingual supplements, liquid oil, oil as a paste, sprays, salves, creams and in edible forms, such as candies or sweets. You can also inhale CBD oil from vapor-releasing pens, similar to the technology for e-cigarettes. This variety also provides a lot of controlled flexibility in terms of concentration, making CBD hemp oil useful and desirable for people of all ages, economic means, and personal needs.
So how does it work? Scientists are still working out the details of how CBD works to calm the mind, though it seems that its effects on serotonin and glutamate production are part of that equation. This comprehensive 2015 review of scientific literature on CBD as a potential treatment for anxiety concluded that CBD has considerable potential and strongly recommended further study.
Unless you've been tuned out to the beauty world these last few months, odds are you've heard of an ingredient called CBD (short for cannabidiol). The buzzy ingredient, which, no, won't get you high, even if ingested as an oral tincture or supplement, has now evolved into a bonafide skin-care trend, with brands offering a luxe spin on what used to be a highly niche category. "With an impressive and evergrowing number of studies finding CBD to be a powerful antioxidant and anti-inflammatory among many other properties, it is now being used to treat pain, anxiety, spasms, and much more," New York City-based aesthetician Jeannel Astarita tells Allure.
Nevertheless, as populations age all across the globe, constant pain brought on by chronic illnesses in the elderly will surely become a matter of public health and compassion. A 2008 study inquired on the efficacy of cannabinoids other than THC in pain management. Painkillers with cannabinoids proved to be well tolerated, with minimum side-effects, and a prospect for low long-term toxicity. Furthermore, a combination of cannabidiol and opioids is thought to be the breakthrough of the future in palliative care.
Some studies have investigated the role of CBD in preventing cancer cell growth, but research is still in its early stages. The National Cancer Institute (NCI) says that CBD may help alleviate cancer symptoms and cancer treatment side effects. However, the NCI doesn’t fully endorse any form of cannabis as a cancer treatment. The action of CBD that’s promising for cancer treatment is its ability to moderate inflammation and change how cell reproduce. CBD has the effect of reducing the ability of some types of tumor cells to reproduce.
