Commission on Narcotic Drugs in Vienna, UNAIDS Executive Director, Michel Sidibé emphasized the urgent need to provide effective services. … As part of its continuing work to demonstrate the benefits of actively scaling up quality programs that are based on human rights and public health needs, UNAIDS released an advocacy brief… [which] gives examples from around the world on the importance of investing in HIV prevention, treatment, care and support programs for people who use drugs; the need to engage people who use drugs in program development; and the importance of implementing strong and effective harm reduction programs” (3/18).
