Tourists come to Zanzibar for traveling but heroin shipped through East Africa is headed for Europe and North America. Suleiman Mauly who stopped using heroin six years ago, operates a network of so-called sober houses that is a drug treatment program includes art therapy, yoga and even acupuncture. This is done by Kassim Nyuni but the sixty percent of those in the program return to heroin. Suleiman Mauly hopes to expand the network in Zanzibar and send former addicts to work with heroin users in prisons.
