The FDA continues to believe the drug approval process represents the best way to ensure that safe and effective new medicines, including any drugs derived from cannabis, are available to patients in need of appropriate medical therapy. The agency is committed to supporting the development of new drugs, including cannabis and cannabis-derived drugs, through the investigational new drug and drug approval process.
The FDA is actively working to learn more about the safety of CBD and CBD products, including the risks identified above and other topics, such as:
The FDA is evaluating the regulatory frameworks that apply to certain cannabis-derived products that are intended for non-drug uses, including whether and/or how the FDA might consider updating its regulations, as well as whether potential legislation might be appropriate. The information we have underscores the need for further study and high quality, scientific information about the safety and potential uses of CBD.
Some CBD Products are Being Marketed with Unproven Medical Claims and Could be Produced with Unsafe Manufacturing Practices
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.
The FDA’s top priority is to protect the public health. This priority includes making sure consumers know about products that put their health and safety at greatest risk, such as those claiming to prevent, diagnose, treat, mitigate, or cure serious diseases. For example, the agency has warned companies to stop selling CBD products they claim are intended to prevent, diagnose, treat, mitigate, or cure serious diseases such as cancer, Alzheimer’s disease, psychiatric disorders and diabetes. While we have focused on these types of products, we will continue to monitor the marketplace for any product that poses a risk to public health, including those with dangerous contaminants, those marketed to vulnerable populations, and products that otherwise put the public health at risk.
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:
Unlike the FDA-approved CBD drug product, unapproved CBD products, which could include cosmetics, foods, products marketed as dietary supplements, and any other product (other than Epidiolex) making therapeutic claims, have not been subject to FDA evaluation regarding whether they are effective to treat a particular disease or have other effects that may be claimed. In addition, they have not been evaluated by the FDA to determine what the proper dosage is, how they could interact with other drugs or foods, or whether they have dangerous side effects or other safety concerns.
Under the FD&C Act, any product intended to diagnose, cure, mitigate, treat or prevent a disease, and any product (other than a food) that is intended to affect the structure or function of the body of humans, is a drug. OTC drugs must be approved by the FDA or meet the requirements for marketing without an approved new drug application under federal law, including drug products containing CBD, regardless of whether CBD is represented on the labeling as an active ingredient or an inactive ingredient.
The FDA issued warning letters to:
The FDA has not approved any CBD-containing drug products other than one prescription drug for the treatment of seizures associated with tuberous sclerosis complex, Lennox-Gastaut syndrome and Dravet syndrome in human patients.
Products Listing CBD as Inactive Ingredient Cited for Unapproved Drug and Misbranding Violations
The U.S. Food and Drug Administration has issued warning letters to two companies for selling products labeled as containing cannabidiol (CBD) in ways that violate the Federal Food, Drug, and Cosmetic Act (FD&C Act). Specifically, the warning letters address the illegal marketing of unapproved drugs labeled as containing CBD. The FDA has not approved any over-the-counter (OTC) drugs containing CBD, and none of these products meet the requirements to be legally marketed without an approved new drug application. The letters explain that, as CBD has known pharmacological effects on humans, with demonstrated risks, it cannot be legally marketed as an inactive ingredient in OTC drug products that are not reviewed and approved by the FDA. Additionally, the letters cite substandard manufacturing practices, including failure to comply with current good manufacturing practices.
The FDA has previously sent warning letters to other companies illegally selling unapproved CBD products that claimed to prevent, diagnose, mitigate, treat or cure various diseases, in violation of the FD&C Act.
“The FDA continues to alert the public to potential safety and efficacy concerns with unapproved CBD products sold online and in stores across the country,” said FDA Principal Deputy Commissioner Amy Abernethy, M.D., Ph.D. “It’s important that consumers understand that the FDA has only approved one drug containing CBD as an ingredient. These other, unapproved, CBD products may have dangerous health impacts and side effects. We remain focused on exploring potential pathways for CBD products to be lawfully marketed while also educating the public about these outstanding questions of CBD’s safety. Meanwhile, we will continue to monitor and take action, as needed, against companies that unlawfully market their products — prioritizing those that pose a risk to public health.”
The products that are the subject of the warning letters issued today have not gone through the FDA drug approval process and are considered unapproved new drugs. There has been no FDA evaluation of whether these unapproved drug products are effective for the uses manufacturers claim, what an appropriate dose might be, how they could interact with FDA-approved drugs or other products or whether they have dangerous side effects or other safety concerns.
FDA is committed to encouraging the development of cannabis-related drug products, including CBD. Those interested in cannabis-derived and cannabis-related drug development are encouraged to contact the relevant CDER review division and CDER’s Botanical Review Team (BRT) to answer questions related to their specific drug development program. The BRT serves as an expert resource on botanical issues and has developed the Botanical Drug Development Guidance for Industry to assist those pursuing drug development in this area. FDA encourages researchers to request a Pre-Investigational New Drug application (PIND) meeting to discuss questions related to the development of a specific cannabis-derived and cannabis-related drug product.
If the IND is authorized by FDA as “safe to proceed” the sponsor may then submit their clinical protocol registration application, including referenced IND number, to DEA to obtain the protocol registration. Once this is received, the sponsor contacts NIDA or another DEA-registered source to obtain the cannabis and/or cannabis-derived substances and they can then begin the study.
FDA reviews the submitted IND. The sponsor must wait 30 calendar days following IND submission before initiating any clinical trials, unless FDA notifies the sponsor that the trials may proceed sooner. During this time, FDA has an opportunity to review the submission for safety to assure that research subjects will not be subjected to unreasonable risk.
The sponsor sends a copy of the IND and clinical protocol, including a LOA (if applicable), to FDA.
Conducting clinical research using cannabis-derived substances that are considered controlled substances under the CSA often involves interactions with several federal agencies. For example:
