Post-legalization shifts in cannabis use among young adults in Georgia-A nationally representative study.

Background And Aim: In 2018, the country of Georgia legalized cannabis for recreational use and decriminalized limited possession. This study aimed to assess whether cannabis use increased among young adults (ages 18-29 years) in Georgia after national policy changes and to evaluate whether perceived access became easier after legalization and current risk factors of young adult cannabis use.

Methods: We used data from the Georgian nationally representative survey administered in 2015 (n = 1308) and 2022 (n = 758), before and after decriminalization.

A citizen science approach to develop a digital intervention to reduce HIV stigma and promote HIV self-testing among adolescents and young adults: a mixed methods analysis from Kazakhstan.

Introduction: Kazakhstan has one of the fastest-growing HIV epidemics in the world, with increasing rates among adolescents and young adults (AYA). Innovative strategies are needed to increase HIV testing uptake and decrease HIV stigma among AYA. Citizen science, defined as the active engagement of the general public in scientific research tasks, promotes and facilitates community engagement throughout the research process.

Mobile addiction treatment and harm reduction services as tools to address health inequities: a community case study of the Brockton Neighborhood Health Center mobile unit.

Opioid overdose deaths continue to increase in the US. Recent data show disproportionately high and increasing overdose death rates among Black, Latine, and Indigenous individuals, and people experiencing homelessness. Medications for opioid use disorder (MOUD) can be lifesaving; however, only a fraction of eligible individuals receive them.

Substance use stigma: A systematic review of measures and their psychometric properties.

Background: Instruments to measure substance use stigma are emerging, however little is known regarding their psychometric properties. While research has evolved to view substance use stigma as a context sensitive international phenomenon that is embedded within cultures, validated self-report measures are lacking and comprehensive reviews of the existing measures are extremely limited. In this systematic review of substance use stigma and shame measures, we aim to contextualize results from existing research, lay the groundwork for future measurement development research, and provide a thorough resource for research scientists currently designing studies to measure substance use stigma.

Socioeconomic Status and CD4 Count Among People with HIV Who Inject Drugs in St. Petersburg, Russia.

Lack of access to resources is a "fundamental cause" of poor HIV outcomes across the care cascade globally and may have the greatest impact on groups with co-existing marginalized identities. In a sample of people living with HIV (PWH) who inject drugs and were not on antiretroviral therapy (ART), we explored associations between access to resources and HIV severity. Fundamental Cause Theory (FCT) sees socioeconomic status/access to resources as a root cause of disease and emphasizes that individuals with limited resources have fewer means to mitigate health risks and implement protective behaviors, which ultimately generates disparities in health outcomes.

Effects of the Communities that Heal (CTH) intervention on perceived opioid-related community stigma in the HEALing Communities Study: results of a multi-site, community-level, cluster-randomized trial.

Background: Community stigma against people with opioid use disorder (OUD) and intervention stigma (e.g., toward naloxone) exacerbate the opioid overdose crisis.

Comparative costs and potential affordability of a multifaceted intervention to improve treatment outcomes among people with HIV who inject drugs in Russia: economic evaluation of the LINC-II randomized controlled trial.

Introduction: The LINC-II randomized controlled trial in St. Petersburg, Russia for HIV-positive adults who inject drugs found that a multi-component intervention including initiation of antiretroviral therapy (ART) during admission to an addiction hospital, strengths-based case management and naltrexone significantly increased 12-month HIV viral suppression and ART retention. We conducted a comparative cost analysis to determine if the 12-month cost of the intervention is affordable within the current Russian health system.

Community advisory board members' perspectives on their contributions to a large multistate cluster RCT: a mixed methods study.

Background: Community advisory boards (CABs) are an established approach to ensuring research reflects community priorities. This paper examines two CABs that are part of the HEALing Communities Study which aims to reduce overdose mortality. This analysis aimed to understand CAB members' expectations, experiences, and perspectives on CAB structure, communication, facilitation, and effectiveness during the first year of an almost fully remote CAB implementation.

Stigma and other correlates of sharing injection equipment among people with HIV in St. Petersburg, Russia.

Stigma that people with HIV who inject drugs experience negatively impacts HIV and substance use care, but stigma's association with sharing injection equipment is not known. This is a cross-sectional analysis of data from two studies of people with HIV reporting drug injection ( = 319) in St. Petersburg, Russia (September 2018-December 2020).

Mobile treatment for opioid use disorder: Implementation of community-based, same-day medication access interventions.

Background: Medications for Opioid Use Disorder (MOUD) are lifesaving, but <20 % of individuals in the US who could benefit receive them. As part of the NIH-supported HEALing Communities Study (HCS), coalitions in several communities in Massachusetts and Ohio implemented mobile MOUD programs to overcome barriers to MOUD receipt. We defined mobile MOUD programs as units that provide same-day access to MOUD at remote sites.

Community-level determinants of stakeholder perceptions of community stigma toward people with opioid use disorders, harm reduction services and treatment in the HEALing Communities Study.

Background: Community stigma toward people with opioid use disorder (OUD) can impede access to harm reduction services and treatment with medications for opioid use disorder (MOUD). Such community OUD stigma is partially rooted in community-level social and economic conditions, yet there remains a paucity of large-scale quantitative data examining community-level factors associated with OUD stigma. We examined whether rurality, social inequity, and racialized segregation across communities from four states in the HEALing Communities Study (HCS) were associated with 1) greater perceived community stigma toward people treated for OUD, 2) greater perceived intervention stigma toward MOUD, and 3) greater perceived intervention stigma toward naloxone by community stakeholders in the HCS.

Rapid access to antiretroviral therapy, receipt of naltrexone, and strengths-based case management versus standard of care for HIV viral load suppression in people with HIV who inject drugs in Russia (LINC-II): an open-label, randomised controlled trial.

Background: Antiretroviral therapy (ART) coverage in Russia is low for people with HIV who inject drugs. HIV and addiction treatment in Russia are not well integrated. We aimed to evaluate an intervention to link people with HIV in addiction treatment to HIV care to achieve HIV viral load suppression.

Provider-patient experiences and HIV care utilization among people living with HIV who inject drugs in St. Petersburg, Russia.

Providers' disrespect and abuse of patients is a recognized but understudied issue affecting quality of care and likely affecting healthcare utilization. Little research has examined this issue among people living with HIV (PWH) who inject drugs, despite high stigmatization of this population. No research has examined this issue in the context of Russia.

A Qualitative Study of Health Equity's Role in Community Coalition Development.

Opioid overdose deaths are dramatically increasing in the United States and disproportionately affecting minority communities, with the increasing presence of fentanyl exacerbating this crisis.
