Impact of Drug Policy Reform on the HIV Risk Environment Among IDUs in Tijuana (El Cuete, Phase IV)

El Bordo -- HIV/SIDA: The Epidemic in Tijuana - Episode 1
The overall objective of Proyecto El Cuete is to evaluate the impact of structural interventions in the legal environment that may influence drug use and HIV risk behaviors of people who inject drugs (PWID) in Tijuana, Mexico. Specifically, we will continue to monitor the impact of Mexico’s federal drug policy reform (narcomenudeo) which partially decriminalized possession of small, specified amounts of cocaine, heroin, methamphetamine and marijuana for personal use. We are also collecting data from an implementation science perspective to examine factors at the institutional, environmental and policy level that impede vs. promote operationalization of the narcomenudeo.
We will also use the El Cuete cohort to prospectively examine the impact of a police education program (PEP) newly designed to align law enforcement and HIV prevention programs in Tijuana. In Mexico and other countries, policing practices are directly and/or indirectly linked to behaviors that increase PWIDs’ vulnerability to HIV, viral hepatitis and STIs. These include syringe confiscation and police misconduct (e.g., physical and sexual abuse). PEPs have been successfully piloted in several locations, but to date, evaluations were limited to brief pre-post assessments of police knowledge, attitudes and/or intentions. Since the impact of PEPs on policing behaviors is unknown, the El Cuete cohort will be utilized to examine the impact of the PEP on PWIDs’ behaviors that influence their risk of acquiring HIV and other blood-borne infections. Our specific aims are:
- To continue to monitor the following impacts of the narcomenudeo in Tijuana with respect to: i) temporal trends in drug use behaviors; ii) PWIDs’ health risks and protective behaviors; iii) experiences with drug treatment; iv) interactions with law enforcement.
- To prospectively examine extent to which police detention and arrest behaviors adhere to narcomenudeo legislation that institutionalizes diversion of substance users to substance use treatment instead of incarceration.
- To study factors at the institutional, environmental and policy level that are impeding vs. promoting implementation of the narcomenudeo legislation.
- To evaluate the impact of a PEP on PWIDs’ outcomes with respect to i) temporal trends in high risk injection behaviors (e.g., rushed injections, needle sharing, injecting in shooting galleries); iii) protective behaviors (e.g., attendance at syringe exchange and drug treatment programs); iii) interactions with law enforcement (e.g., experience with police misconduct, syringe confiscation).
As the narcomenudeo reforms continue to be scaled up, our study will generate important findings that will inform drug policy reforms in Mexico and in other countries. In particular, since the next UN General Assembly Special Session on Drugs will be held in 2016, our study results will be particularly timely. Our study also would be the first to evaluate the impact of a PEP on PWIDs’ risk behaviors, which could serve as a model for other countries. We are also comparing HIV prevalence, incidence and risk behaviors among PWID in Tijuana to a parallel cohort of PWID in San Diego, STAHR II.
