The WADA Prohibited List (World Anti-Doping Agency) is in force worldwide and contains ten different classes of substances (S0 to S9), three kinds of prohibited method groups (M1 to M3) and one substance group (P1) which only apply to certain sport disciplines.
S0-S5: prohibited at all times
S6-S9: prohibited in-competition
M1-M3: prohibited at all times
Beta-blockers: prohibited in particular sports
Which substances or methods shall be added to the list is decided by a body of WADA composed of numerous international scientists: The so-called List Expert Group.
Before inclusion on the Prohibited List, substances and methods are checked for three criteria: for their performance enhancing effects, for potential damage on health and whether they contradict the spirit of sport. Normally, the Prohibited List is changed once per year. Under special circumstances, when we find acute and strong hints of abuse, the List can be changed before the 12-month period. The Prohibited List contains all substances and methods that are forbidden. It is subdivided into sections with substances and methods that are prohibited at all times, substances which are only prohibited in competition and substances which are only prohibited in particular sports.
These are substances with no current approval by any government regulatory health authority for human therapeutic use.
Steroid hormones (abbreviated as steroids) are the ‚classical‘ anabolic agents which structurally are derived from the sex hormone testosterone. An example for this group, apart from steroids like testosterone, nandrolone and stanozolol is clenbuterol, which also has anabolic effects.
One of the best-known substances of this group is Epo (Erythropoietin), an endogenous hormone that is produced in the kidneys and is needed to stimulate the production of red blood cells. Further examples for substances which belong to this group S2. are CERA (Methoxy polyethylene glycol-epoetin beta), hGH (Human Growth hormone), LH (Luteinising Hormone) and Xenon.
Beta-2-Agonists are used to treat asthma. Prohibited Examples are fenoterol, reproterol and vilanterol.
This category includes insulins, aromatase-inhibitors, selective estrogen receptor modulators and other anti-estrogenic substances.
Diuretics are substances that influence the kidneys and cause an increased excretion of urine. Examples are furosemide, hydrochlorothiazide and probenecid.
Manipulations of blood and blood components are, for example, blood transfusions, blood plasma donations and dialyses, and thus, they are forbidden.
Among them, for instance, chemical manipulations of samples, urine substitution or intravenous infusions.
Stimulants are substances that can enhance physical and mental efficiency in the short term. Examples are amfetamines, ephedrine, cocaine, methylphenidate.
Narcotics have strong pain alleviating and relaxing effects. Amongst others including fentanyl and its derivates, morphine, and oxycodone.
Cannabinoids are substances which are either extracted from the hemp plant or synthesised. They contain the active ingredient tetrahydocannabinol (THC). Examples are hashish and marijuana.
