How can I access the NCS-1, 1990-1992 study? I can no longer find it on the SAMHDA site.

The NCS-1, 1990-1992 study has been transferred from the SAMHDA archive to the National Addiction & HIV Data Archive Program (NAHDAP) Archive. NCS-1 data and documentation files can now be accessed through the NAHDAP and ICPSR General Archive websites. We apologize for any inconvenience this transition may have caused.
