WADA Prohibited List: How a Substance Gets Added or Removed – and What About CBD?
Fair play in sports is not just a noble ideal but the foundation of the entire system. For athletes to truly compete based on their training efforts and talent, a shared set of rules is essential. One of the most important elements of this is the annual prohibited list published by WADA, the World Anti-Doping Agency.
This list precisely defines which substances, compounds, and methods are considered banned performance enhancers. The regulation has a dual purpose: on one hand, to protect the health of athletes, and on the other, to ensure victories remain fair and credible.
The list is updated every year, reflecting current scientific research, medical experience, and new challenges emerging in sports. That is why some substances or methods may be added to the banned list over time, while others may be removed based on new knowledge.
But how are these decisions made? How does a substance end up on the banned or allowed list? And how is it possible that CBD—a hemp-derived compound—was banned just a few years ago but is now permitted under WADA rules?
If you’re curious about the behind-the-scenes details, it’s worth joining us as we take you step by step through how the banned list is structured, the criteria for decisions, and how the perception of certain substances and methods may change over time.
What criteria guide the decisions?
It’s not enough for a substance to be new or popular—for WADA to put it on the banned list, it must meet several strict criteria. The decision process is based on a transparent, scientific evaluation system.
WADA examines a substance or method based on three main criteria:
- Performance-enhancing effect – If a substance or compound can influence strength, endurance, concentration, or recovery ability, there is suspicion that it provides an unfair advantage.
- Health risk – Substances that potentially harm athletes’ short- or long-term health can also be banned, even if they do not significantly enhance performance.
- Contrary to the spirit of sport – This includes any method or substance that violates the moral standards, ethics, or fair competition principle of sport.
Decisions are not made by a single body. WADA operates various committees, such as the List Expert Advisory Group, which evaluates scientific and medical data, and the Health, Medical and Research Committee, which develops professional recommendations.
Before updating the banned list, broad consultations take place: anti-doping organizations, sports federations, laboratories, and sometimes athlete representatives all provide input. Committees request specific clinical and laboratory data to make informed decisions.
How does a substance get removed? – The case of CBD
WADA’s banned list is updated annually to reflect the latest scientific and sports medical findings. During updates, not only can new substances be added, but previously banned items can be removed if expert committees determine that continued prohibition is no longer justified.
A good example is CBD, or cannabidiol, which has not been on the banned list since January 1, 2018.
Previously, all forms of cannabis were uniformly banned, but over time increasing evidence showed that different cannabinoids affect the body in distinct ways. CBD holds a special place among these because it is non-psychoactive, does not cause intoxication, and has no mind-altering effects, unlike THC, which remains banned.
Some early studies have looked at CBD’s possible effects, and more athletes have started using CBD oil products or creams as part of their routine.
Based on these facts, WADA’s medical and scientific committees reviewed the classification of the compound. They concluded that:
- CBD does not unfairly enhance performance,
- it does not pose health risks,
- and it does not violate the ethical principles of sport.
As a result, CBD was removed from WADA’s banned list. Athletes should still check product labels carefully and choose THC-free options, since THC remains prohibited.
The Role of Athletes and Their Support Teams
The existence of the WADA banned list alone is not sufficient; athletes and their support teams must continuously monitor current changes. Since the list is reviewed annually—and sometimes a substance’s status changes—staying up to date is essential for competing within the rules.
The updated banned list is published by WADA each year in early October, with new rules coming into effect on January 1 of the following year after a three-month preparation period. This timeframe allows athletes, coaches, medical staff, and sports federations to adapt to any changes.
Athletes should review the current WADA Prohibited List, check the anti-doping resources that apply to their sport and country, and verify any hemp-derived product with current lab documentation before use.
This ongoing communication helps athletes make informed decisions when questions come up about a substance.
Final thoughts
WADA’s banned list is not just a legal document; it’s an evolving system designed to protect the integrity of sport and the health of athletes. That is why it’s not enough to learn the rules once—athletes and their coaches must continuously follow updates to avoid unintended mistakes or doping violations.
The development of the list is based on complex scientific, ethical, and health considerations. The CBD example clearly shows that decision-making is not rigid but responsive to new knowledge. This means the banned list reflects both the progress of science and the changing needs of the sports world.

Medical, Legal, and Anti-Doping Disclaimer
This article is for general information only and is not a substitute for advice from a licensed medical professional, attorney, or qualified sports authority.
It’s important to know that THC (tetrahydrocannabinol)—the psychoactive part of cannabis—is on WADA’s banned list and can trigger a doping violation even at low levels. CBD (cannabidiol) is not on the banned list, but athletes should still check product ingredients and current rules before use.
Other cannabinoids such as CBG (cannabigerol) or CBN (cannabinol) may also be present, and WADA rules may apply to them as well.
Broad-spectrum CBD products may still contain other cannabinoids even when THC has been removed, so competitive athletes should review the product and current rules carefully.
For competitive athletes, CBD isolate products may be a lower-risk option because they contain CBD only, but athletes should still verify the product and current rules before use.
For those not subject to doping controls, broad-spectrum CBD oils are a completely safe alternative, as they offer more complex plant components without THC. Athletes are always advised to choose based on independent laboratory test reports, consult their sports physicians and coaches in advance, and stay informed about the applicable anti-doping rules and WADA resources.
