Drug Reference Phone Line

Speak to an Expert

USADA’s Drug Reference Line® provides a personal resource to understanding prohibited substances based on the UFC 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 4 p.m. MST.

Not able to make a phone call? Email the drug reference team at ufcdrugreference@usada.org.
