Assessing changes in sleep across four weeks among adolescents randomized to incentivized cannabis abstinence.
Published in Drug and alcohol dependence
Withdrawal from cannabis use is associated with sleep disturbances, often leading to resumption of use. Less is known about the impact of abstinence on sleep in adolescence, a developmental window associated with high rates of sleep disturbance. This study investigated effects of sustained abstinence on self-reported sleep quality and disturbance i...

Provide evidence on racial and ethnic differences in biomarkers of exposure from rising e-cigarette use among U.S. adults. Data were drawn from Waves 1-5 of the Population Assessment of Tobacco and Health study (September 2013-November 2019). Differences in biomarkers of exposure and potential harm (BOE/BoPH) across non-Hispanic (NH)-Whites, NH Bla...
Trends in buprenorphine dosage and days supplied for new treatment episodes for opioid use disorder, 2010-2019.
Published in Drug and alcohol dependence
Buprenorphine reduces risk of opioid overdose mortality. However, its benefits are limited by low retention, particularly in early treatment. Optimizing initial dosage may impact retention. However, little is known about the prescription characteristics of new buprenorphine treatment episodes. In a US sample of commercial and employer-sponsored pha...
Prevalence of fentanyl in methamphetamine and cocaine samples collected by community-based drug checking services.
Published in Drug and alcohol dependence
Overdose deaths involving stimulants and opioids simultaneously have raised the specter of widespread contamination of the stimulant supply with fentanyl. We quantified prevalence of fentanyl in street methamphetamine and cocaine, stratified by crystalline texture, analyzing samples sent voluntarily to a public mail-in drug checking service (May 20...
Longitudinal relationships among exclusionary school discipline, adolescent substance use, and adult arrest: Public heal...
Published in Drug and alcohol dependence
Exclusionary school discipline is an initiating component of the school-to-prison pipeline that is racialized and may lead to short- and long-term negative substance use and criminal legal outcomes. However, these impacts, and racial disparities therein, have not been well explored empirically at the individual-level. We analyzed data from the Nati...
Overdose deaths involving synthetic opioids: Racial/ethnic and educational disparities in the eastern and western US.
Published in Drug and alcohol dependence
This study examined racial/ethnic and educational disparities in US synthetic opioid overdose mortality East and West of the Mississippi River. Using restricted-access 2018-2021 mortality data from the Centers for Disease Control and Prevention and population estimates from the American Community Survey, age-standardized rate ratios (SRRs) and 95% ...
Predicting quantity of cannabis smoked in daily life: An exploratory study using machine learning.
Published in Drug and alcohol dependence
Cannabis use is prevalent in the United States and is associated with a host of negative consequences. Importantly, a robust indicator of negative consequences is the amount of cannabis consumed. Data were obtained from fifty-two adult, regular cannabis flower users (3+ times per week) recruited from the community; participants completed multiple e...
Exploring the performance of during-treatment substance use outcome measures in predicting longer-term psychosocial func...
Published in Drug and alcohol dependence
The selection of appropriate efficacy endpoints in clinical trials has been a long-standing challenge for the substance use disorder field. Using data from a large, multi-site National Drug Abuse Treatment Clinical Trials Network trial (CTN-0044; n=474), this secondary data analysis aimed to explore whether specific proximal (during-treatment) subs...
Integration of a geospatially targeted community-based testing approach with respondent-driven sampling to identify peop...
Published in Drug and alcohol dependence
Respondent-driven sampling (RDS), a network recruitment approach, is effective at reaching people who inject drugs (PWID), but other strategies may be needed to reach PWID at risk or living with HIV and/or Hepatitis C (HCV). We examined the impact of integrating geospatially targeted community-based HIV/HCV testing with an RDS survey. PWID were rec...
