Reports that a South African drug called whoonga contains antiretroviral (ARV) medications are wrong. Whoonga is a popular (and illegal)  drug that is smoked and is made up of mostly low-grade heroin. But samples taken by South Africa's University of KwaZulu-Natal found no traces of ARVs. The Treatment Action Campaign, a South African AIDS group, worries the rumors will fuel theft of ARVs, which could jeopardize supplies of meds for HIV-positive people.
