USADA's Drug Reference Line provides athletes, parents, coaches, etc., a personal resource to understanding prohibited substances based on the WADA Prohibited List. A pharmacist 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 (800) 233-0393 within the United States and (719) 785- 2020 outside the country.
