Principle of Strict Liability

In anti-doping, the principle of Strict Liability applies, whereby an athlete is responsible for any prohibited substances found in their urine and/or blood sample collected during doping control, regardless of whether they intended to dope or not. 

Athletes must be aware of the Prohibited List and carefully check any medications or supplements prior to taking them.  IPC recommends that athletes consult a trained professional, such as a doctor, pharmacist or nutritionist, who is best placed to interpret the List and provide advice.
