Scott E. Hadland (born November 19, 1981) is a Canadian-American physician and scientist who serves as a pediatrician, and addiction specialist at Massachusetts General Hospital and Harvard Medical School, where he is the Chief of the Division of Adolescent and Young Adult Medicine. He previously served as an addiction specialist at the Grayken Center for Addiction at Boston Medical Center.
A key finding of Hadland's research has been to confirm that an increase in dollars spent on marketing from the pharmaceutical industry to American doctors was linked to mortality from opioid overdoses one year later.
Research A series of studies led by Hadland provide evidence linking the marketing of opioids directly to doctors, and the addiction epidemic in the United States. Counties where opioid manufacturers offered gifts and payments to doctors were found to have more overdose deaths involving prescription painkillers than counties where direct-to-physician marketing was less aggressive. In this study, which examined marketing in 2014, Insys Therapeutics was responsible for half of all marketing dollars to doctors.
Hadland's work has also examined drug company marketing of stimulant medications to treat attention deficit hyperactivity disorder (ADHD), the effects of prescription drug monitoring programs on adolescent injection drug use, and treatment for teens addicted to nicotine.
Hadland's writing on various health-related topics has appeared in USA Today, CNN and Newsweek. He has also appeared on CNN News to discuss COVID-19 related issues and quoted by ABC News.
Personal life Hadland is married and lives in Boston with his husband, Jason Vassy, and two children.
