Extracts of CBD—either from marijuana or hemp (a cannabis variant that is essentially free of THC)—are sold as an oil or in tinctures. You can also get CBD via a transdermal patch, capsule, sublingual spray, gel, cream, or vapor. Some contain pure CBD extract (or so they say); others—particularly if you’re in a state where recreational marijuana is not legal—will contain hemp extract, which includes CBD as part of its makeup. As of this reporting, recreational marijuana is legal in nine U.S. states and medical marijuana in 29. Don’t miss these 50 weird things that are banned in the United States.
CBD is one of over 110 active cannabinoids inside marijuana plants and is most predominant inside the resin glands (trichomes) of the female cannabis plant. Your body contains cell receptors known as cannabinoid receptors. Cannabinoids, found in cannabis, are agonists that bind to these receptors. Cannabinoid receptors can be found all over the body including, but not limited to, the:
So Herrera, who's experienced her own share of pain due to a shoulder injury followed by a bout of Lyme disease, went to a local herb shop and bought a vial of the oil, which, by some definitions, is legal in all states if it doesn't contain more than 0.3 percent THC – the psychoactive component of cannabis. She began putting seven to nine drops under her tongue first thing most mornings – and was startled by the results. "It's changed my pain level, my anxiety level and my stress level," says Herrera, who already practiced yoga, meditated regularly, ate a healthy diet and tried conventional medical treatments for pain and mobility. "It was shocking," she says, because she thought her patients' reports were due to the placebo effect. "Right now," she adds, "I feel pretty amazing."
Isolates are typically the CBD oil product of choice for those who get drug tested or are sensitive to other cannabinoids such as THC. Products labeled as isolates will generally be highlighted as being 99+% “pure CBD.” Usually, these products will have nothing but CBD in them because the CBD has literally been isolated from everything else. You can find pre-made isolate oils that typically consist of a carrier oil, such as MCT oil, infused with the crystalline isolate powder. You can also find the “raw” CBD crystalline powder or slabs (a form of concentrate) on its own.
Whole plant CBD oils can be made in a variety of ways. The “original” CBD oil was created by Rick Simpson. This method requires you to soak the plant material in a solvent, such as grain alcohol. Once the material soaks, the remaining liquid is full of CBD (and other cannabinoids), you evaporate the solvent and the remaining oil is ready for consumption.
Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.
“There’s no oversight,” says Marcel Bonn-Miller, PhD, adjunct assistant professor of Psychology in Psychiatry at the University of Pennsylvania and author of the JAMA article. Beyond the label, he adds, “There’s no consistency. You know that every Hershey’s bar you buy and every Coke you buy will be exactly the same. But that’s not the case with the majority of CBD products. It’s not unexpected to see variability within a given brand.” This means that you may notice improvements the first time you buy and try a particular product, but none the next.
