International Subcommittee

The International Subcommittee of the NHSN works to provide a framework for multidisciplinary and international interaction for scientists involved in drug abuse research as it pertains to Hispanic populations. The subcommittee aims to foster networking and collegial exchange of ideas that will strengthen the research programs both within the United States as well as in their country.

The International Subcommittee of the NHSN aims at identifying researchers in Spanish-speaking countries interested in collaborating with other investigators, as well as supporting the needs and interests of these researchers. We need this information for two main reasons. Goal of the committee include increasing international member influence in the decisions taken by the international subcommittee, as well as facilitating networking for identification of international members interested in collaboration.
