Who could benefit from this research
✓Could help
Ideal candidates are adolescents and young adults (roughly ages 12–30) who have or may be at risk for prescription drug misuse or polysubstance use.
✕Less likely to help
Young people not exposed to prescription medications or those outside the AYAs age range may not directly benefit.
What this research studies
This project tracks people aged roughly 12 to 30 to map how prescription drug misuse begins, evolves, and relates to other substances over years. Using large national datasets, it will examine patterns by age, birth cohort, and time period to identify when risk is highest and what factors drive polysubstance use. The goal is to inform policies and create better screening and intervention strategies for AYAs at risk. Participants may contribute by providing survey data through established national studies and may benefit indirectly from improved prevention tools.
Why it matters
Potential benefit: If successful, findings could lead to earlier identification of at-risk AYAs and more effective screening and intervention efforts for prescription drug misuse.
How similar studies have gone: Prior work has mapped prevalence and patterns, but this project adds longitudinal APC analyses and polysubstance considerations.
