THC-dominant edibles (like chocolates) can carry an even higher risk. “It can take one or two hours to feel an effect from ingestion as opposed to a few seconds from inhalation,” says Dr. Bonn-Miller. “This makes titration very difficult.” Add to that, an edible is made to taste good. So you can easily eat more than you should in the course of a few minutes—and end up feeling negative effects hours later.
Dr. Devinsky’s research, which was recently published in The New England Journal of Medicine, is beginning to provide that much-needed data in the field of epilepsy research. In a landmark multinational randomized double-blind study for a treatment-resistant form of the condition, subjects taking an oral solution of 20 mg CBD per kilogram of body weight for 14 weeks, along with standard treatment, experienced a 42 percent reduction in drop seizures (the muscles go limp). Those taking a 10 mg CBD per kilogram of body weight saw a 37 percent decrease; patients who got a placebo saw a 17.2 percent decrease. The mechanism hasn’t quite been worked out yet, Dr. Devinsky says, though there’s some evidence that a receptor known as GPR55 may be critical for the anti-seizure effect.
While there is much debate on which form is better, this 2015 study leans in favor of full spectrum CBD oil products. There are many that believe that other cannabinoids, THC especially, are necessary to take full advantage of what cannabis has to offer. Ultimately, however, we are all different and it comes down to the individual user and their needs. If drug testing is a concern, you’re encouraged to seek out CBD isolate products (or terpsolates) or broad spectrum products instead of full spectrum.
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.
Immediately after reading this article I realized this is not the difference I was expecting.  While the USDA says that it takes a chemical analysis to tell the difference between hemp and medical marijuana, for most of us it would only take 2 seconds to notice the difference between a field of hemp and a medical marijuana grow operation.  As far as definition is concerned the two are not so far off from one another. Hemp and marijuana are both cannabis and it would seem that the only real difference is that “marijuana” or more recent term “medical marijuana” is classified as a variety of cannabis with a high percent of THC and, occasionally, high CBD as well.
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.
