Examining a migration-based phenomenon of heroin use in an urban drug scene in Sao Paulo, Brazil

Abstract

PurposeBrazil’s street-based drug use is mostly characterized by non-injection psychostimulant (e.g. crack-cocaine) drug use in Brazil, with limited interventions and service availability. Recently, an influx of multi-ethnic migrants within an urban drug scene in Sao Paulo was associated with heroin use, a drug normatively absent from Brazil. The purpose of this paper is to characterize and compare heroin use-related characteristics and outcomes for an attending sub-sample of clients from a large community-based treatment centre (“CRATOD”) serving Sao Paulo’s local urban drug scene.Design/methodology/approachAll non-Brazilian patients (n= 109) receiving services at CRATOD for 2013–2016 were identified from patient files, divided into heroin users (n= 40) and non-heroin users (n= 69). Based on chart reviews, select socio-demographic, drug use and health status (including blood-borne-virus and other infections per rapid test methods) were examined and bi-variately compared. Multi-variate analyses examined factors independently associated with heroin use.FindingsMost participants were male and middle-aged, poly-drug users and socio-economically marginalized. While heroin users primarily originated from Africa, they reported significantly more criminal histories, drug (e.g. injection) and sex-risk behaviors and elevated rates of BBV (e.g. Hepatitis C Virus and HIV). A minority of heroin users attending the clinic was provided methadone treatment, mostly for detoxification.Originality/valueThis study documented information on a distinct sample of mostly migration-based heroin users in Sao Paulo, Brazil. Based on the local experience, global migration dynamics can bring changes to established drug use cultures and services, including new challenges for drug use-related related behaviors and therapeutic interventions that require effective understanding and addressing.
