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.
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.

Some work-place drug screens and tests detect THC and not the presence of Cannabinoids or other legal hemp based constituents. However, studies have shown that ingesting hemp can cause confirmed positive results. Based on this information, if you are subject to any form of drug screening or testing or are a member of the United States Armed Services, we cannot recommend that you ingest this product. Please consult with your healthcare practitioner as well as your employer or drug screening company.
The same terms could be applied to what's actually in CBD products. While some do contain CBD, others (often marketed as "CBD-rich hemp oil") may have barely any, Asquith says. And depending on state laws, they can include varying levels of THC too – a combination shown to have some benefits, but also drawbacks, of course, if you're not looking for a high. "People will play all these games with the numbers because the consumers aren't really educated in this space yet and it's easy to get taken advantage of," he says. "It's the milligrams of the actual CBD molecule that matter."

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.


Isolate CBD is the CBD gets its extraction from the cannabis plant without other terpenes and cannabinoids. Many users of this CBD type consider this much better than the full spectrum. They go as far enough to get this type of CBD by isolating the CBD from others themselves. They are even different dosage methods and levels for each kind of CBDs and therefore should carefully be in separation for each of the CBD types.
The appeal? Proponents claim CBD can help ease pain, anxiety, depression and stress, boost focus and productivity, improve the immune system, reduce inflammation and more. And – unlike its psychoactive cousin THC – CBD, they say, is harmless, legal and can't get you high. "The known is it's good for you, it helps a lot of people and a lot of things, and you can't hurt yourself," says Phil Asquith, a farmer and producer of extra-virgin olive oil in California, who founded one of the first companies in the CBD space. "The unknown is all the details."
