In today’s episode, Mpho Lakaje speaks to a 36-year-old South African man who uses a drug called Nyaope or Whoonga. It’s a type of black tar heroin often mixed with other powdered substances that include cleaning chemicals. But the problem of substance abuse and addiction isn't limited to one country - and the United Nations says it expects the number of people using drugs in Africa to rise 40% by 2030. Sierra Leone is also dealing with a drug commonly known as Kush, a psychoactive blend of addictive substances. Earlier this year, 23 people died and 20 others went blind after allegedly consuming poisonous alcohol in Kenya. And Malawi also has a concoction notoriously known as “God take me”.
