The Texas College Survey of Substance Use is an example of what can be accomplished by integrating public policy objectives with academic research. The survey is sponsored by the Texas Health and Human Services Commission (HHSC) and has been facilitated by the staff of the Public Service And Administration (PSAA) at Texas A&M University since its inception in 1997.


Similarly, PSAA also administers for HHSC the Texas School Survey of Drug and Alcohol Use, an annual collection of self-reported tobacco, alcohol, inhalant, and substance (both licit and illicit) use data from students throughout the state of Texas.

The Public Service And Administration (PSAA) is an academic research organization conducting public policy research on a variety of social, economic, and civil issues.
