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.
So, many of CBD's popularized benefits aren't well-proven. But are there any harms in trying CBD-containing products? In a word, yes. While any reported side effects from CBD alone are minor (think dry mouth and dizziness), they can be serious if the CBD products interact with other medications, experts say. Since CBD is metabolized by the same enzyme in the liver that metabolizes many conventional medicines and supplements, the chemical can cause the levels of other drugs in the system to rise; in some cases – like for those taking a drug to prevent their bodies from rejecting a donor organ – to a deadly level, Tishler says.
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.

In isolate form, CBD is separated from other cannabinoids found in hemp and cannabis. Previously, users and researchers believed that CBD isolates were more potent than full spectrum CBD hemp edibles. But that myth was eventually proven wrong by different studies performed in recent years. Therefore, full spectrum CBD oil is more effective than CBD isolate.
First, ethanol is a polar solvent. This means that it will readily mix with water and dissolve water-soluble molecules. This creates a great challenge for companies using the ethanol extraction method because chlorophyll is one of the compounds that will easily co-extract. Chlorophyll in the concentrate will result in a dark green coloring and an unpleasant bitter, grassy flavor.

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.
Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.

Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.
