In 2015, with the initiative of three organizations, the Association ŠKUC, Legebitra and DrogArt, Kemseks (Chemsex) program was established. The motive behind it was the recognition that there is an increased risk in the MSM group (men who have sex with men) who use drugs during sex, and that this kind of behavior required new approaches to prevent the spread of sexually transmitted infections. The program is built on the basis of two years of research and interaction with users and is unique in Slovenia in the area of harm reduction. Special emphasis in the program is given to field interventions on the premises where MSM socialize, while the program also provides information via group activities  on-line as well as counseling.
