This funding opportunity announcement (FOA) invites mechanistic studies on the impact of social inequality on the brain and on the substance use trajectory. Applications investigating relevant mechanisms at the behavioral, cognitive, neurocircuitry, cellular, genetics, and epigenetics levels are encouraged.
Exploratory and high-risk research projects are appropriate for this FOA. Applications testing a fully conceptualized and hypothesis-based solid premise founded with adequate preliminary data should consider applying to the companion R01 announcement RFA-DA-22-007.
