You may have noticed that cannabidiol (CBD) seems to be available almost everywhere, and marketed as a variety of products including drugs, food, dietary supplements, cosmetics, and animal health products. Other than one prescription drug product to treat seizures associated with Lennox Gastaut syndrome (LGS), Dravet syndrome (DS), or tuberous sclerosis complex (TSC) in people one year of age and older, the U.S. Food and Drug Administration (FDA) has not approved any other CBD products, and there is very limited available information about CBD, including about its effects on the body.
CBD products are also being marketed for pets and other animals. The FDA has not approved CBD for any use in animals and the concerns regarding CBD products with unproven medical claims and of unknown quality equally apply to CBD products marketed for animals. The FDA recommends pet owners talk with their veterinarians about appropriate treatment options for their pets.
Potential harm, side effects and unknowns
The FDA is concerned that people may mistakenly believe that using CBD “can’t hurt.” The agency wants to be clear that we have seen only limited data about CBD’s safety and these data point to real risks that need to be considered. As part of the drug review and approval process for the prescription drug containing CBD, it was determined that the risks are outweighed by the benefits of the approved drug for the particular population for which it was intended. Consumer use of any CBD products should always be discussed with a healthcare provider. Consumers should be aware of the potential risks associated with using CBD products. Some of these can occur without your awareness, such as:
We are aware that there may be some products on the market that add CBD to a food or label CBD as a dietary supplement. Under federal law, it is illegal to market CBD this way.
Despite the 2018 Farm Bill removing hemp — defined as cannabis and cannabis derivatives with very low concentrations (no more than 0.3% on a dry weight basis) of THC — from the definition of marijuana in the Controlled Substances Act, CBD products are still subject to the same laws and requirements as FDA-regulated products that contain any other substance.
But many people are hoping those regulations will happen soon. Even the CBD industry is concerned and asking for oversight. For instance, without more regulations, organizations like the U.S. Hemp Authority are unable to certify CBD oils as it does with CBD topicals, tinctures, and edibles. And, until that happens, consumers have very little way of knowing what they are getting when they purchase a CBD oil.
If you are considering vaping CBD oil as a way to address a medical concern, talk to your doctor first. The risks associated with vaping and CBD oil are significant and may not provide the benefits you want.

Is Vaping CBD Oil Safe?
Generally speaking, vaping is an unsafe practice regardless of what substances are in the vape pen. And, CBD oil is no exception. In fact, the Centers for Disease Control and Prevention (CDC) has recently linked vaping products to an outbreak of nearly 3,000 lung illnesses that were so serious that even young people were being admitted to the hospital. Meanwhile, nearly 70 people have died from what is now being called EVALI (e-cigarette and vaping associated lung injury). And, the CDC believes thousands more may have admitted to the hospital with lung issues related to vaping.
Because this testing was a such a small sample, the AP noted that their sampling is not representative of the entire CBD market. However, their testing does show just how risky it is to vape CBD oil when there is little to no regulation of the product. Vapers have no idea what they are getting when they take a puff.
Additionally, numerous scientists, doctors, and researchers are concerned with the safety of inhaling CBD oil because little is known about the long-term effects. What’s more, when vaping devices are heated, a chemical reaction takes place in the vapor, which could pose additional risks to the lungs, especially in young people.
Although the CDC has traced many of the EVALI hospitalizations back to vitamin E acetate, a substance used to dilute oils used in vaping, the risks of vaping CBD oil are not without risk, especially if the vape pens are obtained from illicit dealers, online sources, or friends. At least 26 of the EVALI cases were hospitalized after vaping CBD oil.
Some CBD products may contain unwanted surprises. Forensic toxicologists at Virginia Commonwealth University examined nine e-liquids advertised as being 100 percent natural CBD extracts. They found one with dextromethorphan, or DXM, used in over-the counter cough medications and considered addictive when abused; and four with a synthetic cannabinoid, sometimes called Spice, that can cause anxiety, psychosis, tachycardia and death, according to a study last year in Forensic Science International.

Many soldiers return home haunted by war and PTSD and often avoid certain activities, places or people associated with their traumatic events. The Department of Veterans Affairs is funding its first study on CBD, pairing it with psychotherapy.
Is CBD harmful?
CBD is advertised as providing relief for anxiety, depression and post-traumatic stress disorder. It is also marketed to promote sleep. Part of CBD’s popularity is that it purports to be “nonpsychoactive,” and that consumers can reap health benefits from the plant without the high (or the midnight pizza munchies).
Cannabidiol and THC are just two of the plant’s more than 100 cannabinoids. THC is psychoactive, and CBD may or may not be, which is a matter of debate. THC can increase anxiety; it is not clear what effect CBD is having, if any, in reducing it. THC can lead to addiction and cravings; CBD is being studied to help those in recovery.
However, a double-blind study found healthy volunteers administered CBD had little to no change in their emotional reaction to unpleasant images or words, compared to the placebo group. “If it’s a calming drug, it should change their responses to the stimuli,” said Harriet de Wit, co-author of the study and a professor in the University of Chicago’s department of psychiatry and behavioral neuroscience. “But it didn’t.”
This year, 1,090 people have contacted poison control centers about CBD, according to the American Association of Poison Control Centers. Over a third are estimated to have received medical attention, and 46 were admitted into a critical care unit, possibly because of exposure to other products, or drug interactions. In addition, concern over 318 animals poured into the American Society for the Prevention of Cruelty to Animals’ Animal Poison Control Center.
