Drug Reference Phone Line
Speak to an Expert
USADA’s Drug Reference Line® provides a personal resource to understanding prohibited substances based on the WADA Prohibited List. An expert is available to answer questions about the status of a substance; Therapeutic Use Exemptions (TUE); and how that process can be started or carried out. The resource is available Monday-Friday, 8 a.m. to 5 p.m. MST. If you reach our voicemail during office hours, please leave a detailed messaged and we will call you back as soon as possible.
