2024 WADA Prohibited List

The CSCM Nutrition team has reviewed the 2024 WADA Prohibited List and compiled a list of the biggest updates. This list is by no means exhaustive, and athletes are required to review the entire list themselves to make sure they are compliant with the rules.


Dietary supplements can benefit athletes when integrated properly, but the need for expert guidance is necessary to identify suitable products, assess risks, and ensure a positive risk-benefit balance.

Supplements are poorly regulated and may contain prohibited or contaminated substances, have inaccurate labeling, and make false claims. Athletes must be cautious and are liable. Athlete entourages are also liable for Anti-Doping Rule Violations if determined to be complicit. The World Anti-Doping Agency publishes an updated prohibited list every year, it is important for the athletes and their entourages to familiarize themselves with the list and its effective time.

It’s important to consult the Sports Dietitian/Physician before starting any supplement.

2024 WADA Prohibited List Major Changes: Effective January 1st, 2024.

Be aware of the following:


Tramadol, an opioid medicine used for the short-term relief of moderate to severe pain, also part of Canada’s Controlled Drugs and Substances Act since March 2022; is now prohibited in-competition. This is due to its potential to enhance performance and adversely affect athlete health.

It is important to note:

  1. The use of Tramadol in or close to competition puts athletes at risk for a positive anti-doping test.
  2. Stay familiar with competition and international federation rules for when in-competition periods start.
  3. The recommended washout period, as provided by WADA, for therapeutic use of tramadol is 24 hours.

The “washout period” is the time between the last dose and the start of in-competition, usually at 11:59 p.m. the day before the event.


Donation of blood plasma via Plasmapheresis will be permitted if performed in an official registered blood donation facility.


New Glucocorticoids wash-out periods for rectal route administration out-of-competition. Athletes using rectal glucocorticoids should adhere to new guidelines to determine when they must stop using them before competition.

2024 WADA Monitoring Program

Substances in the Monitoring Program are not banned. WADA labs test the monitored substances to track usage patterns, but athletes won’t face anti-doping violations for using these substances.

In 2024, the following substances have been added:

  1. Ecdysterone (Anabolic agent) was added to examine patterns of use in and out-of-competition.
  2. Gonadotrophin-releasing hormone (GnRH) analogues were added to monitor patterns of use in females under 18 years only in and out-of-competition.
  3. Hypoxen (polyhydroxyphenylene thiosulfonate sodium) was added to examine prevalence of use in and out-of-competition.
  4. Bupropion, caffeine, nicotine, phenylephrine, phenylpropanolamine, pipradrol and synephrine were added to monitor patterns of use in-competition only.
  5. Tapentadol and dihydrocodeine (Narcostics) were added to monitor patterns of use in-competition.
  6. Semaglutide (GLP-1 analog) was added to examine prevalence of use in and out-of-competition.

Remember: As an athlete, you are liable and responsible for your own compliance. Review the WADA list yearly, check your supplements and medication every time you purchase new supply, and track all your information systematically.

If you have any questions or concerns about supplementations, medication and the WADA Prohibited list, please reach out to your CSCM Sport Dietitian.
