Sharon B. Garrett MPH, MA

Sharon Garrett, MPH, MA is a Research Scientist at the University of Washington’s Addictions, Drug & Alcohol Institute (ADAI). She has overseen the implementation of multiple protocols within the National Drug Abuse Treatment Clinical Trials Network, evaluating psychosocial and pharmacotherapy interventions for treating substance use disorders. Currently, she is Project Director for CTN-0080 and CTN-0099, both of which will compare injectable to sublingual buprenorphine in the treatment of opioid use disorder. 

Since 2012, she has been an active member of ADAI’s Cannabis Education & Research Program (CERP), where she has collaborated on various projects exploring public health impacts of cannabis legalization in WA State.  She has been a Project Coordinator in the development of three online trainings; a CME course for healthcare providers on the use of cannabis to treat chronic pain, and two cannabis trainings designed for helpline staff and for the public. She has also contributed to projects funded by the WA State I-502 dedicated marijuana to better understand adult cannabis use in the context of legalization, including focus groups with adult cannabis users, cannabis retail store staff, and parents who use cannabis. In 2022, this team evaluated policy options for reducing harms related to high-THC products, resulting in a package of recommendations for the WA State legislature.

Ms. Garrett is a member of UW’s Internal Review Board – Committee J, where she reviews studies involving human subjects from across the university to ensure ethical treatment of study participants. She also coordinates the ADAI Lunch-and-Learn, a series of informal, monthly presentations by ADAI staff and guest speakers.
