  • Association Between Lifetime Hallucinogen Use and Valvular Heart Disease

    Open Access•Kevin H Yang, Miranda Rasmussen et al.•ARTICLE•Journal of Psychoactive Drugs•2026

    Recent literature suggests potential associations between hallucinogen use and valvular heart disease (VHD) due to prolonged activation of serotonin 5-HT2B receptors, which may lead to valvular fibrosis – a condition also linked to drugs including fenfluramine and pergolide. Despite these concerns, epidemiological studies exploring this association are lacking. This exploratory analysis investigated associations between lifetime hallucinogen use …

  • Differences in opioid use and overdose among younger and older justice-impacted adults

    Open Access•Meghan M O’Neil, Wayne Kepner et al.•ARTICLE•Health & Justice•2025

    BACKGROUND: Justice-impacted persons aged 40 and up with substance use disorders (SUD) demonstrate increased health risks and health disparities relative to general population peers. Persons with SUD are less likely to age out of criminal behavior, appearing on criminal dockets, in jails, prisons, and under community supervision throughout the life course, with greater community-level cost burdens as they age. Justice system involvement presents …

  • Prevalence and Correlates of Lifetime Ecstasy/MDMA Use Among Asian American and Pacific Islander Adult Populations in the United States, 2015–2020

    Open Access•Wayne Kepner, Kevin H Yang et al.•ARTICLE•Journal of Psychoactive Drugs•2025

    Little is known about ecstasy/MDMA use among Asian American and Pacific Islander populations. Research is important because AAPIs face unique cultural factors that may influence use. We estimated the prevalence and correlates of lifetime ecstasy/MDMA use based on a representative sample of US AAPI adults aged ≥18 from the 2015-2020 National Survey on Drug Use and Health. An estimated 5.1% of AAPI adults used ecstasy in their lifetime. Compared to…

    Wayne Kepner, Meredith C Meacham et al.•ARTICLE•Substance Use & Misuse•2022

    Background: Digitally-mediated peer support may improve opioid use disorder (OUD) recovery. Our objective was to examine the types and sources of stigma that people seek support for in online OUD recovery communities (subreddits) on Reddit. Methods: We extracted all posts containing stigma keywords from three subreddits as well as a random sample that do not contain stigma keywords. We conducted deductive content analysis to confirm that the post…

This study explores the societal response to the first wave of the pandemic outbreak in Italy, look…
