Article
Interactions with the police may result in police brutality, particularly for people of color. Black men who have sex with men (BMSM) face disproportionate risk of police contact and may experience elevated violence risk. We measured longitudinal associations between discriminatory police harassment (DPH) and subsequent risk of a range of interpers...
Article
Black sexual minority men (BSMM) and Black transgender women (BTW) have disproportionately high HIV prevalence, making HIV testing critical for treatment and prevention. Racism and homophobia may be barriers to testing among BSMM/BTW, particularly in the context of previous incarceration. We analyzed a subsample (n = 655) of HIV-negative, previousl...

Article
Full-text available
Injecting drugs for the first time almost always requires assistance from an experienced person who injects drugs (PWID). While there has been moderate amount of research on PWID who assist with first injections, most of this research has focused on identifying characteristics of PWID who assist with first injections. We do not have a formal model...
Chapter
In this chapter, we present notes on the harm reduction approach to drug use with special focus on the current opioid epidemic in United States. Harm reduction is the most recent, and we believe the most effective, framework for addressing the problems of psychoactive drug use in large, complex societies. Harm reduction arose in opposition to previ...
Article
Background Psychiatric comorbidities are frequent among people who inject drugs, they are associated with a poorer prognosis and need to be addressed. Their interaction with daily heroin injection requires clarification. Methods A cross-sectional survey was conducted among PWID recruited in the city of Haiphong, Vietnam, by respondent-driven sampl...
Article
Full-text available
Introduction In Vietnam, people who inject drugs (PWID), who are the major population infected by hepatitis C virus (HCV), remain largely undiagnosed and unlinked to HCV prevention and care despite recommended universal hepatitis C treatment. The data on the outcomes of HCV treatment among PWID also remain limited in resource-limited settings. The...

Background and Aims While substance use can lead to incarceration, the disruptive effects of incarceration may lead to, or increase psychosocial vulnerability and substance use. Using causal inference methods, we measured longitudinal associations between incarceration and post-release substance use among Black men who have sex with men (BMSM), pop...
Article
Background: Hepatitis C virus (HCV) infection is associated with substantial morbidity and mortality among people who use drugs (PWUD). Health disparities related to race/ethnicity and immigration status also increase the risk of HCV infection and decrease the probability of linkage to care. Effective, curative treatment is now available for HCV in...
Article
Full-text available
In Vietnam, harm reduction programs to control HIV among people who inject drugs (PWID) were implemented approximately 10 years ago. Since then, the HIV prevalence has declined in this population, however, the impact of these programs on the rate of new HIV and Hepatitis C (HCV) infections remains unknown as high mortality can exceed the rate of ne...
Article
Background: Overdose deaths increased exponentially in the United States to be the leading cause of adult injury deaths, and declining economic opportunity may contribute.
