Interact Our data

We have created two interactive tools that allow you to quickly filter down to the datapoints you need. The NSDUH SAE tool allows you to quickly see data by state and substate areas. The Quick Statistics tool provides state profiles for TEDS, N-SSATS, and N-MHSS data.

Analyze Our data

We have two data analysis systems (PDAS for public use and the restricted-use RDAS) available for researchers. As part of PDAS, there is also a NSDUH SAE tool to quickly see data by state and substate areas.
