Getting to Zero: We Can't Do It Without Addressing Substance Use.

HIV elimination by 2030 cannot occur without attention to substance use. It cuts across risk groups and affects sexual risk behavior, treatment adherence, and systemic processes such as immunity and inflammation. There continues to be often limited attention to non-injection drug use and the syndemic character of HIV and substance use. There is a need for a more comprehensive approach that addresses the multiple influences of substance use on HIV prevention and care, integrating this into evidence-based services and building on the successes of comprehensive Seek, Test, Treat, and Retain approaches to substantially reducing new HIV cases among drug users.
