AI Article Synopsis
- The study explores how various interpersonal and intrapersonal factors impact young adults' use of cigarettes, e-cigarettes, and cannabis over time.
- It analyzes data from over 3,000 participants to identify predictors of substance use, such as depressive symptoms, personality traits, and parental substance use.
- Findings suggest that interventions should focus on high-risk groups and consider individual differences to effectively address substance use behaviors.
Article Abstract
Background And Objectives: Limited longitudinal research has examined differential interpersonal and intrapersonal correlates of young adult use and use frequency of cigarettes, e-cigarettes, and cannabis. This study aimed to address these limitations.
Methods: We analyzed five waves of longitudinal data (2018-2020) among 3006 US young adults (M = 24.55, 44% male, 32% sexual minority, ~30% racial/ethnic minority). Two-part latent growth models examined likelihood of past-month cigarette, e-cigarette, and cannabis use (binary part) and days used (continuous part) and identified predictors (depressive symptoms, personality traits, adverse childhood experiences [ACEs], parental use) of baseline use and changes over time.
Results: Regarding baseline past-month use (27% cigarettes, 38% e-cigarettes, 39% cannabis), depressive symptoms, ACEs, and parental substance use predicted use outcomes (i.e., likelihood, frequency) for each product; extraversion predicted cigarette and e-cigarette use outcomes; openness predicted e-cigarette and cannabis use outcomes; conscientiousness negatively predicted cigarette and cannabis use outcomes; and agreeableness negatively predicted cannabis use frequency. Regarding longitudinal changes, conscientiousness predicted accelerated increase of cigarette use frequency at later timepoints; depressive symptoms predicted increases in likelihood of e-cigarette use but the association weakened over time; and parental cannabis use predicted decreased cannabis use frequency but the association weakened over time.
Discussion And Conclusions: Young adult substance use interventions should target high-risk subgroups and focus on distinct factors impacting use, including chronic, escalating, and decreasing use.
Scientific Significance: This study advances the literature regarding distinct predictors of different substance use outcomes and provides unique data to inform interventions targeting young adult cigarette, e-cigarette, and cannabis use.

Background: Understanding factors influencing electronic cigarette (e-cigarette) trial in adolescents is crucial for shaping policies and interventions to reduce consumption and potentially prevent addictive tendencies, particularly in countries with weak regulations like Guatemala.
Objective: We aimed to longitudinally assess predictors of e-cigarette trial among Guatemalan adolescents surveyed in 2019, 2020, and 2021.
Methods: Students (13 to 18 years old) from nine private schools completed self-administered questionnaires about e-cigarette use and associated risk factors.
Flavored E-Cigarette Sales Restrictions and Young Adult Tobacco Use.
JAMA Health Forum

Department of Health Policy and Management, Yale School of Public Health, New Haven, Connecticut.
Importance: More than one-quarter of US residents live in states or localities that restrict sales of flavored electronic nicotine delivery systems (ENDS), often as a means to reduce youth vaping. Yet, how these policies affect young adult vaping and smoking remains unclear.
Objective: To estimate the effects of ENDS flavor restrictions on ENDS use and cigarette smoking among young adults (age 18-29 years) in the US.

: Electronic cigarettes (e-cigarettes) are commonly used by former smokers as an alternative product to conventional cigarettes and also by young adults and adolescents to deliver nicotine. E-cigarettes are thought to be a less harmful and more socially acceptable alternative to tobacco smoking; however, their long-term effects on health, including oral health, are currently unknown. : A literature search for relevant papers indexed in the literature from 2016 to 2023 was conducted using the PubMed, Scopus, and Google Scholar databases.

Background: The use of heated tobacco products (HTPs) among Korean adults has been steadily increasing since they were first introduced in 2017. It is known that smoking combustible cigarettes (CCs) adversely affects the serum lipid profile and increases the risk of cardiovascular disease. However, the health impacts of HTPs remain under- researched.
