: North America experiencing an unprecedented overdose epidemic, with data estimating almost 110,000 overdose deaths occurring in 2022 in the United States (US). To address fatal overdoses in the US, community organizations and local health departments in some jurisdictions have expanded community distribution of naloxone, and increased overdose prevention education, and other harm reduction supplies and services (e.g., fentanyl test strips, drug checking programs) to reduce harm for people who use drugs (PWUD). : Understanding how PWUD manage overdose risk within the context of these expanded services is important for ensuring public health services are meeting their needs. Semi-structured qualitative interviews were conducted with 25 PWUD who were accessing harm reduction services in Rhode Island. Data were imported into NVivo where they were coded and analyzed thematically. : Our findings demonstrate the complexity of managing overdose risk in the context of a fentanyl drug supply. While most participants were concerned about overdosing, they sought to manage overdose risk through their own harm reduction practices (e.g., testing their drugs, going slow) and drug purchasing dynamics, even when using alone. : Study findings point to the need to implement and scale-up community-level interventions to better support PWUD within the context of the current US overdose crisis.

Objective: While opioid overdose has begun to decrease in recent years, stimulant overdose has continued to increase and has not been adequately addressed. Unlike opioid use disorder, there are no medications approved by the U.S.

Introduction: Prescription opioid dose reductions can raise the risk of adverse events for patients on long-term opioid therapy for non-cancer pain. Evidence on whether risks differ by age or sex is needed to support tailored clinical decision-making.
Methods: In 2024, a secondary analysis of an observational cohort study was conducted across 8 U.

Sex offender registration and notification (SORN) policies have significantly destabilizing material and psychosocial collateral consequences for people required to register. There are strong theoretical and anecdotal reasons to believe that SORN policies likely increase substance-use-related harms for registrants. However, no research has directly examined relationships between SORN policies and substance-use-related harms.

This two-year retrospective analysis examined whether cannabis use among BZD users was associated with changes in outcomes of (1) all-cause mortality, (2) hospitalizations, (3) emergency department (ED) visits, and (4) whether it demonstrated BZD-sparing effects on prescription quantity over time.
Methods: Using data from Yale New Haven Health System, we conducted a retrospective, longitudinal cohort study among BZD users.
Background Fentanyl is a potent synthetic opioid widely used for pain management and anesthesia, but the high prevalence of its misuse and its key contribution to overdose fatalities in the United States have made it a major drug of concern. Although fentanyl's onset, duration, and toxicity depend on its pharmacokinetics and specific tissue distribution, most studies have focused primarily on plasma concentrations, leaving its distribution in critical tissues largely unexplored (this knowledge gap limits our understanding of fentanyl's clinical effects, tissue accumulation, and the factors influencing its efficacy and safety). Here, we report the radiosynthesis of [ C]fentanyl for PET imaging and present a preliminary whole-body pharmacokinetic study in rodents.
