Drug testing screening methods used at North American Natural Bodybuilding Federation (NANBF), Organization of Competitive Bodybuilders (OCB),  and International Fitness & Physique Association (IFPA) events are a means to determine eligibility. If competitors can not successfully pass any screening methods used, they will either not be allowed to compete if determined prior to the event (Ex. Polygraph test), or will be disqualified and be removed from official results if determined after an event (Ex. Urine test).

Competitors cannot have used any substances indicated as being banned for NANBF/OCB/IFPA competitions during the specified duration periods.

All participants at each NANBF, OCB, and IFPA show must submit to polygraph screening for use of banned substances (polygraph test results from OCB or NANBF amateur shows can be honored for other OCB or NANBF amateur shows held within three weeks of each other). OCB and NANBF events that are designated as IFPA pro qualifiers conduct urinalysis testing for Bodybuilding and Figure Open and Masters pro qualifying placements in addition. IFPA pro events conduct urinalysis testing for cash prize winners in each category.

Competitors are responsible for ensuring they are tested at events. Polygraph examiners supply the NANBF, OCB, and IFPA home offices with lists of contestants tested after each show. Urinalysis results go directly to the NANBF/OCB/IFPA home offices. If it's discovered any participants who should have been polygraph tested were not, they will be disqualified and removed from the official results. If any pro qualifying winners do not provide a urine sample at IFPA pro qualifiers, eligibility to compete in the IFPA pro federation will be void. If any cash prize placement winners at IFPA pro shows do not provide a urine sample at the event, they will be disqualified and removed from the official results

Forms of drug testing in addition to the required may be requested of select Bodybuilding, Figure, Fitness or Fitness Model at any event at the promoter's discretion and expense. This could include urinalysis, voice stress, blood, saliva, hair testing or other means of detection. Competitors are ultimately responsible for substances they take. If urine test results come back positive for any banned substance, competitors are disqualified regardless of what may have been responsible for the positive result.

IFPA athletes are subject to out of contest (spot) drug testing throughout the year. IFPA members are responsible for keeping the IFPA up-to-date whenever changes to contact information occur.

Products that contain ingredients that have chemical names similar to anything on the banned substance list could potentially cause a positive urine test result. Check with the NANBF/OCB/IFPA drug testing officials if uncertain as to whether a particular product is disallowed or not.

• Athletes, like all others, may have illnesses or conditions that require them to take particular medications. If the medication an athlete is required to take to treat an illness or condition happens to fall under the prohibited list, a therapeutic use exemption may give that athlete the authorization to take the needed medicine. Criteria for granting a therapeutic use exemption are 1.) The athlete would experience significant health problems without taking the prohibited substance or method, 2.) The therapeutic use of the substance would not produce significant enhancement of performance, and 3.) There is no reasonable therapeutic alternative to the use of the otherwise prohibited substance or method
