One Exception: The Story of Epidiolex
While the vast majority of CBD products remain unapproved, the prescription drug Epidiolex marks a major exception. In June 2018, the FDA approved Epidiolex, a purified form of cannabidiol, for the treatment of seizures associated with Lennox-Gastaut syndrome and Dravet syndrome in patients aged one year and older. This drug went through the rigorous testing and review process required for all new medications, including extensive clinical trials to prove its safety and effectiveness. Its approval is a testament to the potential therapeutic value of CBD, but it also highlights the strict standards and evidence needed to earn an official stamp of approval from the federal agency. The key difference is that Epidiolex is a pharmaceutical drug, not a dietary supplement or conventional food product.
Why Other CBD Products Aren't Regulated as Drugs
For a product to be sold as a drug, it must undergo the FDA's New Drug Application (NDA) process. This is a costly and time-consuming process that requires manufacturers to demonstrate that their product is both safe and effective for its intended use through controlled clinical trials. Most CBD brands on the market do not have the resources or intent to go through this process, and as a result, their products are not considered drugs and cannot make claims about treating specific diseases. This leads to a critical regulatory gray area, particularly for consumer products like oils, tinctures, and edibles.
The FDA's Stance on CBD in Foods and Dietary Supplements
Since the passage of the 2018 Farm Bill, which legalized hemp and its derivatives, the CBD market has boomed, but the FDA's position on CBD in foods and supplements has remained firm. The agency has concluded that it is unlawful to introduce CBD into interstate commerce as a food additive or market it as a dietary supplement. This is largely due to two key reasons:
- Exclusionary Clause: Federal law prohibits marketing a substance as a dietary supplement or adding it to food if it has been previously investigated or approved as a drug. Because Epidiolex was approved as a drug, CBD falls under this 'exclusionary clause', effectively preventing its use in foods and dietary supplements under current regulations.
- Safety Concerns: The FDA has identified significant safety concerns related to CBD, including potential liver injury, interactions with other medications, and risks for certain populations like pregnant women and children. In January 2023, the FDA announced that existing regulatory pathways for food and supplements are not appropriate for managing these risks and that a new framework is needed from Congress.
Potential Risks of Unregulated CBD Products
Without consistent FDA oversight, the quality, labeling, and safety of non-pharmaceutical CBD products can be highly unreliable. Consumers should be aware of several potential risks associated with these unregulated products, which can include:
- Inaccurate Labeling: Studies, including one published in JAMA, have shown that many non-FDA approved CBD products are inaccurately labeled, containing either more or less CBD than claimed. This inconsistency makes proper dosing difficult.
- Contaminants: Some products have been found to contain harmful contaminants like heavy metals and pesticides, which are not always screened for in an unregulated market.
- THC Content: Some CBD products may contain higher levels of THC than legally permitted, posing a risk of intoxication or a failed drug test.
- Unproven Claims: Many companies make unsubstantiated health claims, marketing CBD as a cure or treatment for a wide range of serious conditions without any scientific backing.
Comparison: FDA-Approved Epidiolex vs. Unregulated CBD Products
| Feature | FDA-Approved Epidiolex | Unregulated CBD Products |
|---|---|---|
| Regulatory Status | Approved as a prescription drug | Largely unapproved; sold in regulatory gray areas |
| Evidence | Rigorously tested in clinical trials for specific conditions | Limited scientific evidence for claims; efficacy is unproven |
| Manufacturing Standards | Produced under strict cGMP standards | Variable standards, may be produced without proper oversight |
| Labeling | Guaranteed accurate concentration and dosage | Inaccurate labeling is common, leading to inconsistent dosing |
| Safety & Side Effects | Known safety profile with controlled risks and warning labels | Unknown long-term safety; risks include liver injury and drug interactions |
| Intended Use | Specific medical use for rare seizure disorders | Marketed for general wellness or unproven therapeutic uses |
| Availability | Requires a doctor's prescription and dispensed by a specialty pharmacy | Sold online, in stores, and gas stations without medical oversight |
The Path Forward: Congressional Action and Consumer Safety
The FDA has explicitly stated that regulating CBD requires a new framework, one that does not currently exist under their food or dietary supplement authorities. The agency has asked Congress to step in and create specific legislation to allow for proper oversight, including clear labeling, content limits, and other consumer protections. In the meantime, the FDA continues to issue warning letters to companies making false or unsubstantiated claims. Until Congress acts, the marketplace for non-pharmaceutical CBD products will remain largely unregulated, putting the onus on consumers to research products carefully and consult healthcare professionals.
Conclusion: Consumer Due Diligence is Key
While interest in CBD's potential benefits continues to grow, it is crucial for consumers to understand the current regulatory landscape. No, the vast majority of CBD products sold in stores or online are not FDA approved. The only exception is the prescription medication, Epidiolex, which has undergone extensive testing for specific seizure conditions. For all other products, consumers should proceed with caution, conducting thorough research and seeking guidance from a healthcare provider. The lack of federal oversight means products may be inaccurately labeled and potentially contain harmful contaminants, making informed decision-making vital for safety.
