Research Overview:

Dr. Smith’s research focuses on behavioral and policy aspects of cannabis use, and ultimately seeks to address the question, “Under what circumstances can cannabis yield therapeutic benefits, and how might cannabis-related harms be minimized?” Her work addresses this question through studies that examine: 1) overlapping aspects of nicotine and cannabis and their impact on use behaviors and health; 2) contextual factors that contribute to cannabis use behaviors and associated health outcomes (e.g., policy and use contexts); and 3) cannabis use in the context of cancer prevention, care, and symptom management.

Dr. Smith is also interested in new and emerging forms of drug delivery, specifically electronic vaping products and heat-not-burn products used to administer nicotine and cannabis. Her work integrates mixed methods including laboratory, clinical, and observational studies. She is also involved in development and analysis of longitudinal cohort studies of nicotine use, including the International Tobacco Control (ITC) Survey and Population Assessment of Tobacco and Health (PATH) Study.
