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% had more CBD than indicated, while 26% had less, and some had unexpected THC. “There’s a 75% chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.

Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD.

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.
The most abundant cannabinoid in hemp oil, making up over 90% of the cannabinoid content, cannabidiol or CBD is non-psychoactive and is the focus of the benefits from hemp oil. CBD has little affinity for CB1 or CB2 receptors, the main points of interaction for cannabinoids in the endocannabinoid system, and instead acts as an indirect antagonist of cannabinoid agonists, possibly allowing CBD to temper the high caused by THC. Our Gold Label RSHO™ is almost 25% CBD, making up most of oil’s weight. All other cannabinoids come in under 0.4% by weight.
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:
With the rapid rise in the popularity of CBD in everything from vape juice to lattes, many people are asking- “what is CBD oil?”.
