And Welty said the studies that have featured humans for these other CBD uses have either been case reports or studies that did not compare results against a control group that did not use the oil.
Last month, a U.S. Food and Drug Administration advisory panel unanimously recommended approval of the CBD medication Epidiolex to treat two rare forms of childhood epilepsy.
This could mean that people taking anti-epilepsy drugs alongside CBD will need to adjust their dosage downward to avoid side effects, Welty noted.
“About 2 to 3 percent of individuals taking CBD actually had to discontinue because their liver enzymes went so high it was of concern to the people running the study,” he said.
Worse, about 1 in 5 CBD products contained the intoxicating pot chemical THC, Bonn-Miller and his colleagues found.
Cannabidiol is extracted from the flowers and buds of marijuana or hemp plants. It does not produce intoxication; marijuana’s “high” is caused by the chemical tetrahydrocannabinol (THC).
This is the potential use for CBD with the most evidence after usefulness in epilepsy, but “there’s a decent gap between those two,” he said.
One perk of hemp seed oil is that it's completely cleared by the Food and Drug Administration (FDA), and legal to buy or sell pretty much anywhere. With CBD oil, the laws are a bit trickier and vary from one state to the next. As a rule of thumb, CBD oils are legal if they contain less than 0.3% THC content. THC is the chemical compound that gives marijuana its psychoactive effects; in other words, it's the part that gets you high, which is why it's limited in all but a handful of states.
If you are searching for CBD products, here are a few things to look for as you shop:
If you want the added natural benefits of hemp seed oil, but with a less natural taste, Green Roads is the brand to go for. Its products are formulated by a licensed pharmacist and come with a few flavor options: natural, apple kiwi, and mint breeze. This CBD oil formula is a bit thicker than other oils on the market, and it’s also available in full-spectrum and broad-spectrum options for anyone who wants a THC-free CBD oil.
Hemp oil vs. CBD oil
Since the FDA has yet to formally evaluate CBD products, the market is highly unregulated. As such, consumers are advised to do their homework and to be careful when browsing different CBD oil products online.
In recent years, CBD oil has become an increasingly popular natural remedy. Its proponents vouch for its abilities to alleviate a wide range of symptoms, and people can't seem to get enough of this non-intoxicating cannabis extract.
As CBD has grown in interest, there has been renewed interest in hemp oil as well. In fact, there are some common questions about CBD oil vs. hemp oil because both products are extracted from the hemp plant, yet have very different effects on the body.
There are also some important distinctions in the way CBD oil and hemp seed oil are processed. The latter is usually made through cold-pressing hemp seeds to create a dark, thick oil that is highly concentrated and nutrient-rich. CBD oil, on the other hand, is made from different processes such as ethanol or CO2 extraction, which draw from the whole hemp plant and create a final product that contains more beneficial plant compounds, like cannabinoids and terpenes.
