  • Machine Learning of Smoking Relapse: The Role of Racial Differences and E-Cigarette Vaping Characteristics on Former Smokers

    Open Access•H D Dai, Fang Qiu et al.•ARTICLE•Journal of Racial and Ethnic…•2026

  • Modified risk tobacco product (MRTP) claim, nicotine strength and nicotine label on ZYN perceptions and use intentions among adults who are currently smoking cigarettes

    Haijing Ma, Jianfeng Zhang et al.•ARTICLE•Tobacco Control•2026

    The proposed MRTP claim may have limited effectiveness in nudging switching from cigarettes to ZYN among adults who currently smoke. More education is needed to better inform people of ZYN health harm and nicotine risks

  • Discrete Choice Experiment on Financial Incentives for Engaging Young Adults in Vaping Cessation Programs

    Tzeyu L Michaud, Kaeli Samson et al.•ARTICLE•Substance Use & Misuse•2025

    INTRODUCTION: Contingency management involves rewarding individuals based on objective evidence of behavioral changes. This study explores preferences for financial incentives in vaping cessation programs. METHODS: A discrete choice experiment (DCE) was conducted among young adult current e-cigarette users aged 19-29. DCE attributes (and levels) included reward amount ($100, $300), reward schedule (consistent value, escalating value), reward proc…

  • Trends in e-cigarette flavour use and demographic correlates among US youth from 2020 to 2023

    Dayoung Bae, Tahsin Rahman et al.•ARTICLE•Tobacco Control•2025

    During 2020-2023, most US youth vaped non-tobacco flavours. Reducing the availability of: (1) fruit/ice-fruit flavoured e-cigarettes might impact most US youth, especially younger teens and (2) menthol-flavoured e-cigarettes might especially impact youth vulnerable to frequent vaping and rural youth

  • Changes in quality of life and mental health outcomes related to vaping cessation among US adults

    H D Dai, Brian Young•ARTICLE•Tobacco Control•2025

    This study demonstrates that vaping cessation is associated with improved quality of life and mental health. Future research should continue to explore long-term health outcomes and develop targeted interventions for vaping cessation

  • Tobacco control messages for individuals who use both cigarettes and e-cigarettes: A randomised trial comparing biomarker outcome with cessation experience narratives

    Roma Subramanian, Kaeli Samson et al.•ARTICLE•Tobacco Control•2025

    A biomarker outcome narrative message that highlights the efficacy of quitting smoking and vaping by presenting evidence-based, objective biomarkers of toxicant exposure may be a persuasive message format in anti-dual use messaging

  • Trends in Cannabis and Tobacco Use by Racial and Ethnic Groups Among U.S. Youth: 1991–2021

    Open Access•H D Dai, Hongying Dai•ARTICLE•Journal of Racial and Ethnic…•2025•References: 1

  • Biomarkers of metal exposure in adolescent e-cigarette users: Correlations with vaping frequency and flavouring

    Andrew Kochvar, Gary Hao et al.•ARTICLE•Tobacco Control•2024

    Vaping in early life could increase the risk of exposure to metals, potentially harming brain and organ development. Regulations on vaping should safeguard the youth population against addiction and exposure to metals

  • Randomised experiment for the effect of ‘Tobacco-Free Nicotine’ messaging on current e-cigarette users’ perceptions, preferences and intentions

    Kendra L Ratnapradipa, Kendra Ratnapradipa et al.•ARTICLE•Tobacco Control•2023

    Tobacco-free nicotine marketing message may prompt the transition to and promote a price premium for such products. With the proliferation of products in the market, comprehensive regulation of emerging synthetic vaping products is needed

  • A review of bidimensional acculturation and STI/HIV-related sexual risk behaviours among Hispanic youth

    Mariam Adeyeba, Cynthia Schmidt et al.•ARTICLE•Culture Health & Sexuality•2023

    A growing body of research suggests that acculturation may play a role in the disproportionate likelihood of sexual risk behaviour and STI/HIV infection among Hispanic youth in the USA. We systematically reviewed the relationship between acculturation and STI/HIV-related sexual risk behaviour among Hispanic youth aged 13-24 by reviewing studies that have used a bidimensional acculturation approach. Electronic databases were searched with the sear…

  • Hierarchical Analysis of Disparities in Suicidal Outcomes With Intersection of Sexual Minority and Gender Among U.S. Youth, 2017

    Open Access•Dylan Scoggins, Ali S Khan et al.•ARTICLE•Health Education & Behavior•2022

    Sexual minority youth have a higher risk of suicidal behaviors than their straight peers. Despite this alarming trend, there is limited information on how health-risk factors are systematically associated with suicidal outcomes in relation to the intersection of sex and sexual orientation identity. Data from the 2017 Youth Risk Behavior Survey (Grades 9–12, N = 14,108) were analyzed to examine three distinct suicidal outcomes (i.e., suicidal idea…

  • Using place-based characteristics to inform FDA tobacco sales inspections: Results from a multilevel propensity score model

    Open Access•H D Dai, Lisa Henriksen et al.•ARTICLE•Tobacco Control•2021

    The multilevel PSM predicts the RVSM with a good rank order of retail violations. The model-based approach can be used to identify hot spots of retail violations and improve the sampling plan for future inspections

  • Ice’ flavoured e-cigarette use among young adults

    Adam M Leventhal, H D Dai et al.•ARTICLE•Tobacco Control•2021

    Young adult use of ice flavoured e-cigarettes may be common and positively associated with combustible tobacco use, nicotine vaping frequency and dependence and use of disposable e-cigarette devices. Further study of the prevalence, determinants and health effects of ice flavoured e-cigarette use is warranted

  • Racial Disparities of E-Cigarette Use Among US Youths: 2014‒2019

    H D Dai, Hongying Dai et al.•ARTICLE•American Journal of Public Health•2021•Cited by: 1•References: 23

    Objectives To evaluate disparities in youth e-cigarette use patterns and flavor use by race/ethnicity over time. Methods We used data from the US 2014–2019 National Youth Tobacco Survey (NYTS) to examine trends in dual use (co-use of e-cigarettes and cigarettes or other tobacco products), occasional (≤ 5 days) versus frequent use (≥ 20 days) in the past 30 days, and flavor use among current (past-30-day) e-cigarette users (n = 13 178) across raci…

  • Online popularity of Juul and Puff Bars in the USA: 2019–2020

    H D Dai, Jianqiang Hao•ARTICLE•Tobacco Control•2020

    The popularity of Puff Bar on Google Search suggests that users may replace cartridge-based vaping products with disposable e-cigarettes in the circumvention of the partial flavour ban. Continuous surveillance and further assessment are needed to prevent potential loopholes in tobacco regulation

  • Prevalence of e-Cigarette Use Among Adults in the United States, 2014-2018

    H D Dai, Hongying Dai et al.•ARTICLE•JAMA•2019

    This population epidemiology study uses 2014-2018 data from National Health Interview Surveys to assess trends in prevalence of current and daily e-cigarette use by US adults and to characterize trends by sociodemographic and smoking status among young adults (18-24 years).

  • The effects of tobacco control policies on retailer sales to minors in the USA, 2015

    H D Dai, Hongying Dai et al.•ARTICLE•Tobacco Control•2017

    We observed associations of tobacco regulations and neighbourhood social characteristics with tobacco retailers' compliance with under-age sales laws. This study provides evidence to support stronger tobacco regulations and control policies in reducing youth access to tobacco products

  • Predicting Asthma Prevalence by Linking Social Media Data and Traditional Surveys

    Open Access•H D Dai, Hongying Dai et al.•ARTICLE•The Annals of the American…•2017•References: 33

    Asthma is one of the most common chronic diseases that has a profound impact on people’s well-being and our society. In this study, we link multiple large-scale data sources to construct an epidemiological model to predict asthma prevalence across geographic regions. We use: (1) the Social Media Monitoring (SMM) data from Twitter ( N = 500 million tweets/day), (2) the 2014 Behavioral Risk Factor Surveillance System (BRFSS) ( N = 464,664), and (3)…

  • Mining social media data for opinion polarities about electronic cigarettes

    H D Dai, Hongying Dai et al.•ARTICLE•Tobacco Control•2016

    The organic-against tweets raised public awareness of potential health risks and could aid in preventing non-smokers, adolescents and young adults from using e-cigarettes. Opinion polarities about e-cigarettes from social networks could be highly influential to the general public, especially youth. Further educational campaigns should include measuring their effectiveness

  • Geographic density and proximity of vape shops to colleges in the USA

    H D Dai, Hongying Dai et al.•ARTICLE•Tobacco Control•2016

    Vape shops are more likely to be located near private institutions and colleges in cities as opposed to rural areas. Smoke-free and e-cigarette-free campus policies have had significant effects in reducing the density of vape shops but have not reduced the proximity of vape shops to colleges. Regulations on the sale and advertisement of e-cigarettes to youth and young adults are critically needed
