Sayon Mandal from India received the 2023 College on Problems of Drug Dependence (CPDD) International Committee Award for Best International Research Poster. This award is presented to a NIDA International Forum research poster participant selected by a review panel organized by the CPDD International Committee. The poster—“Barriers to Treatment of Substance Use in Transgenders”—presented findings of a scoping review of studies assessing factors that influence seeking treatment for substance use among transgender individuals. The review found that suboptimal engagement of transgender people in substance use services was due to several factors, including structural barriers such as the lack of treatment services tailored to the needs of transgender people and anticipated or felt stigma. However, the analysis concluded that well-designed, culturally sensitive research in this field is scarce, particularly from developing countries.
