Addiction is one of the nation’s most common and deadly medical conditions. The Substance Abuse and Mental Health Services Administration, the nation’s leading federal behavioral health agency, estimates 44.6 million Americans had a substance-use disorder in 2025, including 25.7 million with alcohol-use disorder. The Centers for Disease Control and Prevention estimates 70,000 Americans died from drug overdoses that year.
The University of Virginia just appointed a leading addiction specialist to chair its Department of Psychology and Neurobehavioral Sciences at UVA Health. Dr. Nassima Ait-Daoud Tiouririne is also the medical director of UVA’s office-based addiction treatment program, where psychiatrists, nurses and social workers treat people with substance-use and behavioral addictions, like gambling.
