Why Does the FDA Keep Sending Warning Letters About CBD?
Over the past few years, cannabidiol (CBD) has surged in popularity as a natural wellness product, appearing in everything from oils to gummies to skincare. Yet, alongside this booming market, most consumers are probably aware of an ongoing issue: the Food and Drug Administration (FDA) frequently sends warning letters to CBD companies about their marketing and labeling practices. You might wonder, why does the FDA keep cracking down on CBD products despite its widespread use? In this article, we'll break down the basics of CBD, explain the legal and regulatory landscape, clarify FDA-approved uses versus over-the-counter (OTC) products, and highlight why quality tools like certificates of analysis (COAs) are critical for consumers.
CBD Basics: Understanding Cannabidiol vs. THC
First, it's important to understand what CBD is and how it differs from tetrahydrocannabinol (THC), the psychoactive compound in cannabis responsible for the "high."
- CBD (Cannabidiol): A non-intoxicating compound found in hemp and marijuana plants. It does not cause the euphoric or impaired feelings typical of THC.
- THC (Tetrahydrocannabinol): The psychoactive ingredient found predominantly in marijuana. THC causes intoxication and is the compound most tightly regulated under federal law.
The 2018 Farm Bill legalized hemp cultivation federally, defining hemp as cannabis plants containing less than 0.3% THC by dry weight. This distinction allowed for hemp-derived CBD to be sold legally, but the presence of THC must be minimal to comply with federal law.
FDA-Approved CBD Use vs. Over-The-Counter (OTC) Products
One source of confusion lies in the difference between FDA-approved CBD medications and the countless OTC CBD products available today.
FDA Approval: Epidiolex as a CBD Medication
Currently, the FDA has only approved one CBD-based prescription drug: Epidiolex. Epidiolex is approved to treat severe seizure disorders such as Dravet syndrome and Lennox-Gastaut syndrome. This means it has passed rigorous testing for safety and efficacy at defined doses under medical supervision.
The OTC CBD Market: Different Standards
By contrast, most CBD products found on store shelves or online are marketed as dietary supplements or wellness products without FDA approval. These products have:
- Not undergone clinical trials confirming safety or effectiveness.
- Not been evaluated for proper dosage or potential interactions with medications.
- Claims that often lack scientific evidence, including miracle-cure assertions for anxiety, pain, or other health issues.
The FDA's warning letters often target companies making unsubstantiated treatment claims, which can mislead consumers and pose health risks.
The Legal Landscape: 2018 Farm Bill and THC Limits
The 2018 Farm Bill helped legalize hemp and hemp-derived products at the federal level, but with key caveats:
- Hemp must contain less than 0.3% THC by dry weight.
- The law does not grant automatic FDA approval for all hemp-derived products, especially those marketed with health claims.
- The regulation of CBD as a food additive or dietary supplement remains complex and under FDA review.
Because of these nuances, labels or marketing slogans like "THC-free" often require careful scrutiny, ideally backed up by batch-specific Certificates of Analysis (COAs). Unfortunately, some companies fail to provide transparent lab testing results, which frustrates regulators and consumers alike.
Quality Variation Among CBD Products: Why Certificates of Analysis (COAs) Matter
One major challenge with CBD products is the wide variation in quality and potency. Unlike pharmaceuticals, OTC CBD is largely unregulated at the manufacturing level, which means:
- CBD content may be lower or higher than the label claims.
- THC levels sometimes exceed legal limits, risking intoxication or positive drug tests.
- Products can contain contaminants like pesticides, heavy metals, or residual solvents.
This is where batch-specific Certificates of Analysis (COAs) come in. A COA is an official lab report that details:
- Exact cannabinoid content (CBD, THC, others).
- Testing for contaminants such as microbes and chemicals.
- The date and batch number to ensure the report matches the product purchased.
Companies like Joy Organics often provide COAs on their websites, allowing consumers to verify product quality independently. However, not all companies do this, even when labeling phrases like "THC-free," which can be misleading without proof.

Why the FDA Sends Warning Letters About CBD
The FDA issues warning letters to companies that fail to comply with the agency’s regulations regarding the marketing and safety of CBD products. Common reasons include:
- Making unapproved health claims: Claims that CBD can cure, treat, or prevent diseases such as cancer, anxiety, depression, or COVID-19 without scientific evidence.
- Marketing CBD as a dietary supplement: Currently, CBD is not approved as a dietary supplement ingredient, so marketing products as such violates FDA rules.
- Labeling inaccuracies: Including incorrect cannabinoid content or failing to provide batch-specific COAs.
- Unsafe manufacturing practices: Use of contaminants or failure to follow good manufacturing protocols.
These violations can lead to regulatory actions, fines, or forced product recalls. The FDA’s primary concern is consumer safety and preventing misleading marketing.

How Consumers Can Navigate the CBD Market Safely
To avoid falling victim to overhyped claims or low-quality products, here are some tips:
- Look for batch-specific COAs: Verify THC levels are under 0.3% and check for contaminants.
- Beware of miracle-cure language: Legitimate CBD products will not promise to cure diseases or replace prescribed meds.
- Choose reputable companies: Brands like Joy Organics maintain transparency and provide lab testing data.
- Consult your healthcare provider: Especially if you’re on medications that may interact with CBD.

The FDA's ongoing warning letters to CBD companies underscore a key reality: despite billions of dollars in sales, the CBD market remains largely unregulated regarding safety, quality, and truthful marketing. While CBD itself is not the villain—being a promising compound with legitimate medical uses in some contexts—consistent oversight is crucial to protect consumers from exaggerated claims and subpar products.
