reporter: uniformsre compulsory, here at the treatment and rehabilitation center for drug addicts at camp bagong diwa in metro manila. patients wear white t-shirts with red shorts, which either they or their families have paid for. those sent to rehab with dr. leabres are charged 80 euros when they begin, and then 60 euros a month. those who can't afford the fees are given subsidies. dr. leabres: our challenge is to help people understand that an addict has a medical condition. he can be a frie, he c be a relative, he can be your son, or your husband or wife -- and all of this is part of you. help them. reporter: but not everyone is heeding this message. elected president in 2016, rodrigo duterte is waging war on drugs. 8000 spected drug pushers and users have been kied, many at the hands of the police or so-calledeath squads. more than a million have voluntarily turned themselves in and gone to prison in a bid to survive. the prisons are filled to bursting. and for these people, going cold turkey is a matter of life or death. others volunteer to go into >> the killings aren't right.
