The Longitudinal Study of Stimulant Use Disorder

This project is a five-year observational study that will use a variety of assessments and tasks to phenotype participants with lifetime or current Stimulant Use Disorder as well as healthy control individuals. The data collection will include collecting urine samples for diagnostic tracking, socio-demographic and lifestyle factors, clinical and behavioral assessments, blood-based biomarkers, genomics, cell-based assays, EEG, and MRI to establish phenotypic biosignature subtypes over the longitudinal timeline.
