Funds requests for biospecimen and data access from the ABCD, HBCD and PATH studies on adolescent brain development and tobacco use.

Between cyclesNational Institutes of HealthGlobal

Three of NIH's largest cohort studies already hold biospecimens most researchers could never collect on their own, and the limiting factor is access rather than new data collection.

This mechanism lets the scientific community request access to biospecimens from the Adolescent Brain Cognitive Development (ABCD) Study, the HEALthy Brain and Child Development (HBCD) Study, and the Population Assess

Requests for access to biospecimens and associated data from the Adolescent Brain Cognitive Development Study, the HEALthy Brain and Child Development Study, and the Population Assessment of Tobacco and Health Study, for research that maximises the scientific value of these limited samples and advances understanding of genetic and environmental factors — including substance exposure — affecting health across the lifespan.
