USADA Drug Reference Phone Line

USADA's Drug Reference Line provides athletes, parents, coaches, etc., a personal resource to understanding prohibited substances based on the WADA Prohibited List. An expert is available to answer questions athletes may have about the status of a substance; whether a Therapeutic Use Exemption (TUE) is needed; and how that process can be started or carried out. The resource is available Monday through Friday 8 a.m. to 4 p.m. MST. The number is within the United States and outside the country.
