Over the past year, the U.S. Food and Drug Administration has embarked on a comprehensive evaluation of cannabidiol (CBD) products, with a focus on educating the public about the risks and unknowns of these products, gathering the science needed to better understand both these safety concerns and potential benefits to inform our regulatory approach, as well as taking steps when necessary to address products that violate the law in ways that raise a variety of public health concerns.
Today, we are providing updates on our efforts in this area, including several new steps in areas of education, research and enforcement with the ultimate goal of continuing to protect the public health and working to provide market clarity.
Educating the Public About Potential Risks of Using CBD
We’re seeing CBD being marketed in a number of different products, such as oil drops, capsules, syrups, food products, such as chocolate bars and teas, cosmetics and other topical lotions and creams, as well as products marketed for pets and other animals – and we understand consumers are seeking out these novel products for a variety of perceived health-related or other reasons.
But as the agency has stated before, we are concerned that some people wrongly think that the myriad of CBD products on the market have been evaluated by the FDA and determined to be safe, or that using CBD ‘can’t hurt.’ Aside from one prescription drug approved to treat two rare, severe pediatric epilepsy disorders, no other CBD products have been evaluated or approved by the FDA.
We remain focused on educating the public about the number of questions that remain regarding CBD’s safety. There may be risks that need to be considered before using CBD products outside of the monitored setting of a prescription from your health care provider.
In particular, the agency recently updated the public on concerns about potential harm from CBD products, including potential liver injury, interactions with other drugs and male reproductive toxicity, as well as side effects such as drowsiness. In addition, there is still much we do not know about other potential risks. For example, other than the approved prescription drug, we know little about the potential effects of sustained and/or cumulative use of CBD, co-administration with other medicines, or the risks to vulnerable populations like children, pregnant and lactating women, the elderly, unborn children and certain animal populations. This does not mean that we know CBD is unsafe to these populations or under these circumstances, but given the gaps in our current knowledge, and the known risks that have been identified, we also are not at a point where we can conclude that unapproved CBD products are safe for use. We encourage Americans to consult with their health care providers before using CBD products.
We will continue to expand our educational efforts on this front. This includes consumers broadly, specific populations where there are additional, important health considerations, as well as health care professionals who must understand these risks when talking to their patients. We will also continue to update our online resources for consumers, researchers and industry, as well as sustain multiple lines of communication with Congress, industry, researchers and our regulatory partners at the federal, state, local, territorial, tribal and international levels to share and collect needed information and hear a variety of perspectives.
Closing Knowledge Gaps in Both Safety and Potential Benefits
The marketplace for CBD-containing products is quickly evolving and it is critical that we work together with stakeholders and industry to develop high-quality data to close the knowledge gaps about the science, safety and quality of many of these products, as well as further evaluate any potential benefits outside of the one FDA-approved drug product to treat two rare, severe pediatric epilepsy disorders.
To address the questions and concerns we’ve already raised, we’re seeking reliable and high-quality data. This includes data on, among other things: the sedative effects of CBD; the impacts of long-term sustained or cumulative exposure to CBD; transdermal penetration and pharmacokinetics of CBD; the effect of different routes of CBD administration (e.g., oral, topical, inhaled) on its safety profile; the safety of CBD for use in pets and food-producing animals; and the processes by which “full spectrum” and “broad spectrum” hemp extracts are derived, what the content of such extracts is, and how these products may compare to CBD isolate products.
Given the importance of answering these questions, we’re exploring a number of ways to address the data gaps as quickly as possible. This includes encouraging, facilitating and initiating more research on CBD, providing venues for industry and researchers to share new data with the agency and identifying opportunities to further collaborate with our federal partners at Centers for Disease Control and Prevention, Substance Abuse and Mental Health Services Administration and National Institute on Drug Abuse on this important issue.
Importantly, the Agriculture Improvement Act of 2018 – which, among other things, changed federal law so that cannabis and cannabis derivatives with very low levels of the psychoactive intoxicating component of cannabis, delta-9 tetrahydrocannabinol (THC) are no longer controlled substances – has opened significant new opportunities for research, and as that body of research develops and grows, there will be considerably more information available. In particular, there’s been an increased interest in drug development from CBD and other compounds found in cannabis and we are working to support drug development as much as possible.
First, given all the research and activity in this space, we are taking new steps to provide a public and transparent way for stakeholders to provide new and emerging information to us in real time as it becomes available. To this end, in the coming days we are re-opening the public docket we established for our May 2019 public hearing. The docket provides a valuable conduit for submission of scientific data on CBD to the agency, so we have decided to extend the comment period indefinitely to allow the public to comment and to share relevant data with the agency. As the agency continues to move forward to explore viable pathways for CBD products outside the drug context, this extension will allow stakeholders to continue to provide relevant data as research in this area evolves.
This docket also includes a mechanism for a stakeholder to submit data or information that the stakeholder believes to be confidential. We hope that this will enable responsible industry participants, academic researchers, and other stakeholders to share relevant information with the FDA – including information about specific products, which could help inform appropriate regulatory steps.
We also are working to generate data to help inform our work in this area. For example, the FDA’s Office of the Chief Scientist recently awarded a grant to the FDA’s National Center for Toxicological Research to conduct a study to better understand the effects of CBD exposure during pregnancy. Additionally, we’ve initiated a research study in partnership with the University of Mississippi to evaluate the levels of CBD and THC in a sample of cosmetic products to assess sensitization of THC and CBD topically, and dermal penetration.
As data become available that are high-quality, reliable and relevant to our evaluation of CBD products that fall under the FDA’s purview, we will be able to refine – and, perhaps in some cases, revise – our thinking and approaches.
Monitoring the Marketplace with a Focus on Greatest Risk to Public Harm
As we work to educate the public and close the knowledge gaps to further guide our approach to CBD products, we will continue to monitor the marketplace and take appropriate action against unlawful CBD products that pose a risk of harm to the public.
We have seen many CBD products being marketed with claims of therapeutic benefit, such as treating or curing serious diseases such as cancer and Alzheimer’s disease, or other drug claims, without having gone through the drug approval process. The proliferation of such products may deter consumers from seeking proven, safe medical therapies for serious illnesses – potentially endangering their health or life.
We also have serious concerns about products that put the public at risk in other ways. For example, we are aware of the risks posed by product contaminants such as heavy metals, THC or other potentially harmful substances. We also have significant concerns about products marketed with false claims or statements such as omitted ingredients, incorrect statements about the amount of CBD, products marketed for use by vulnerable populations like children or infants, and products that otherwise put the public health at risk.
As we move forward, we are currently evaluating issuance of a risk-based enforcement policy that would provide greater transparency and clarity regarding factors the agency intends to take into account in prioritizing enforcement decisions. Any enforcement policy would need to further the goals of protecting the public and providing more clarity to industry and the public regarding the FDA’s enforcement priorities while we take potential steps to establish a clear regulatory pathway.
Our ongoing efforts related to CBD, including the steps we’re announcing today, are in line with our mission to protect the public, foster innovation and promote consumer confidence. We recognize the significant public interest in CBD and we must work together with stakeholders and industry to develop high-quality data to close the substantial knowledge gaps about the science, safety and quality of many of these products. We are committed to working efficiently to further clarify our regulatory approach to these products – as always, using science as our guide and upholding our rigorous public health standards.
The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices. The agency also is responsible for the safety and security of our nation’s food supply, cosmetics, dietary supplements, products that give off electronic radiation, and for regulating tobacco products.
