Infodrogas_VIH is an app developed by Working Group on HIV (TWG) which aims to reduce damage in people with HIV on antiretroviral therapy using drugs for recreational use and / or other substances. The central tool is a seeker of interactions, which lets you enter antiretroviral medications you take and a number of recreational drugs and / or substances frequently used without medical supervision -such as sedatives, steroids, erection enhancing drugs, among others, and check for interactions between HIV medications and each of those substances or recreational drugs. The resort also provides access to news and information of interest and alerts issued by the organization Energy Control, reporting on adulteration or incidents observed in their chemical drug testing, a service offered free of charge and allows users to use safer recreational drugs.
