Anti-retroviral drugs used to treat HIV/Aids are being bought and smoked by teenagers in South Africa to get high.
Reports suggest that the drugs are being sold by patients and even healthcare staff for money.
Schoolchildren have been spotted smoking the drugs, which are ground into powder and sometimes mixed with painkillers or marijuana.
Aids patients themselves have been found smoking the drugs instead of taking them as prescribed.
