In 2017, WADA announced that it would remove CBD from its banned list starting in 2018. The change came as a surprise to many athletes, coaches, and sports federations.
Why did the change matter? For decades, many cannabis derivatives were classified as banned substances in competitive sports. The new rule raised an obvious question: what changed, and what does it mean in practice?
Below, we’ll answer that question and explain what CBD is, how it differs from THC, and why THC remains prohibited.
What is CBD and how does it differ from THC?
The cannabis plant contains many active compounds known as phytocannabinoids. For decades, hemp and many of its extracts and derivatives appeared on the banned substances list in competitive sports, even when they did not contain psychoactive compounds.
The best-known of these compounds is THC, or tetrahydrocannabinol. It has been a focus of anti-doping rules because it can produce intoxicating effects, and it remains prohibited in competition settings.
CBD, or cannabidiol, is generally described as non-intoxicating. Researchers are still studying how it may affect the body, and the evidence is not yet conclusive. Some athletes include it in their routine, but results vary.
Why Was CBD Eventually Allowed?
WADA considers several criteria when deciding whether to add a substance to its prohibited list, including performance concerns and health risk. CBD was removed in 2018, while THC remained prohibited.
In recent years, several scientific studies have not found clear evidence that CBD improves endurance performance. For example, a 2024 clinical trial found no significant difference in runners’ performance after CBD use.
Other studies are still exploring CBD’s possible effects during recovery, but the evidence is limited and still developing. A 2021 literature review suggested there is still more to learn about how CBD may be studied in sports settings.
Research is still in the early stages, and competitive athletes should check the rules and product contents carefully before using CBD.
What Was the Impact?
WADA’s decision to remove CBD from the banned list received mixed reactions in the sports community. Some athletes and coaches saw it as a positive step, while researchers continued to study how CBD may relate to recovery, discomfort, inflammation, and sleep. The evidence is still being evaluated.
Not all countries and sports federations have adopted the change in the same way. In some places, CBD can still fall into a gray area, especially if the product’s THC-free status is not clear. Athletes should check the rules that apply to their sport and location.
It’s important to remember that being removed from the banned list does not mean every CBD product is automatically allowed for athletes.
There are several reasons for this:
- THC remains banned under WADA rules, and many CBD products may contain trace amounts, which can lead to a positive doping test. Athletes subject to testing should review product contents carefully.
- CBD products can vary widely in quality, purity, and composition by manufacturer, and labels may not always match what’s actually inside the product. That’s why it’s important to choose carefully.
- For competitive athletes, THC-free products are generally the safer starting point, but labels and applicable rules still need a careful review.
- Athletes are responsible for the substances found in their body, even if a product was taken unintentionally.
Athletes should choose CBD products from reliable sources and review any available lab test information to help confirm THC-free status before buying, while also checking the rules that apply to them.
Practical Tips
Using CBD in sports requires both legal and practical awareness. Product quality and composition can vary widely, so athletes need to review the specific product and understand the rules that apply to them.
A common issue when buying CBD is unclear or misleading labeling. For example, the difference between “broad-spectrum” and “full-spectrum” isn’t always obvious, and full-spectrum products may contain THC. For athletes subject to testing, even trace amounts of a prohibited substance can have serious consequences.
That’s why it’s especially important to:
- Learn the label terms, such as isolate, broad-spectrum, and full-spectrum,
- ask for any available independent laboratory test report for the product,
- Avoid unknown brands, aggressive marketing, or prices that seem too good to be true.
- Know that anti-doping rules are strict, and intent may not prevent a violation if a prohibited substance is found.
In sports, even small product-labeling or ingredient issues can create major problems. Careful product selection is part of being professional and staying informed.
Key Takeaways
WADA’s decision to remove CBD from the banned list changed the conversation around CBD in sports, but it did not remove every concern. Product composition and reliability still matter, especially for competitive athletes.
As research continues, more data may emerge about how CBD is studied in sports. For now, awareness, informed decisions, and careful product review remain the most important factors.
In our next article, we’ll look at how CBD policy changes may affect athletes in practice.

Important Legal and Anti-Doping Note
This article is for general information only and is not a substitute for advice from a medical, legal, or sports professional.
It’s important to know that THC (tetrahydrocannabinol), the psychoactive component of cannabis, is on WADA’s banned list and can create testing risk even in small amounts. CBD (cannabidiol) itself is not prohibited by WADA, but athletes should still review product contents carefully.
Other cannabinoids, such as CBG (cannabigerol) and CBN (cannabinol), are also part of the broader cannabinoid conversation. Under WADA rules, they are prohibited substances for competitive athletes.
This is especially important because broad-spectrum CBD products may still contain other cannabinoids. Competitive athletes should review product details carefully and understand the rules that apply to them.
For competitive athletes, CBD isolate is often the simplest format to review because it contains only CBD, but product quality and applicable rules still need to be checked.
For people who are not subject to doping control, broad-spectrum CBD oil products may be an option, but product composition can vary. Athletes should review product details carefully, talk with a qualified sports medicine professional, and stay up to date on the rules that apply to them.
