Perceptions of Harm and Addictiveness for Nicotine Products, THC e-Cigarettes, and e-Cigarettes with Other Ingredients Among Adolescents, Young Adults, and Adults
BACKGROUND: Perceptions of health harms and addictiveness related to nicotine products, THC e-cigarettes, and e-cigarettes with other ingredients are an important predictor of use. This study examined differences in perceived harm and addiction across such products among adolescents, young adults, and adults. METHODS: = 6,131, ages 13-40 years old) in which participants reported perceived harm and addictiveness for 11 products (cigarettes, dispos…
Engagement, Mental Health, and Substance Use Under In‐Person or Remote School Instruction During the Covid ‐19 Pandemic
BACKGROUND: Adolescents' school engagement, mental health, and substance use have been major concerns during the COVID-19 pandemic, particularly given disruptions to school instruction. We examined how the instructional setting was associated with academic and health-related outcomes within an adolescent cohort followed during the pandemic. METHODS: During 3 semi-annual follow-up surveys, adolescents (N = 1066 students; 2242 observations) from 8 …
Use of Emerging and Conventional Oral Tobacco Among Adolescent and Young Adult E-Cigarette Users
Background: National surveillance assessing use of novel oral tobacco products (OTPs; nicotine pouches, lozenges, and gums not approved for tobacco cessation) among adolescents and young adults is limited. Objectives: To assess OTP behaviors in a sample of adolescent and young adult e-cigarette users, including use prevalence, dual/poly use with other products, and associated demographics. Methods: A national (United States) cross-sectional surve…
Impact of Local Flavored Tobacco Sales Restrictions on Policy-Related Attitudes and Tobacco Product Access
BACKGROUND: As of September 2020, more than 300 state and local jurisdictions restrict the sales of flavored tobacco, with some including menthol. AIMS: To evaluate the impact of local ordinances restricting the sale of flavored tobacco, we surveyed Californians regarding policy support and perceived access to flavored tobacco. METHODS: In 2019, we conducted an online survey of 3,075 California youth and young adults recruited via social media, a…
Does virtual versus in-person e-cigarette education have a differential impact
Background: E-cigarette prevention education aims to mitigate adolescent e-cigarette use. Such education is increasingly delivered through virtual/video-based teaching platforms (e.g. Zoom, Google Classrooms). However, there is little evidence about the effectiveness of virtual e-cigarette education compared to in-person education on adolescents' knowledge about e-cigarettes, perceived addictiveness and intent to try e-cigarettes, cigarettes, and…
Adolescents, Young Adults, and Adults Continue to Use E-Cigarette Devices and Flavors Two Years after FDA Discretionary Enforcement
This study assesses the use of e-cigarette devices and flavors using a large, cross-sectional survey of adolescents, young adults, and adults (N = 6131; ages 13−40 years old; Mage = 21.9) conducted from November to December 2021, 22 months after the FDA announced its prioritized enforcement policy against some flavored pod/cartridge-based e-cigarettes. We analyzed the patterns of use by age group: adolescents and young adults (AYAs) under 21 (min…
Nicotine Dependence from Different E-Cigarette Devices and Combustible Cigarettes among US Adolescent and Young Adult Users
E-cigarettes, the most popular tobacco product among adolescents, vary widely in design and nicotine composition; thus, different devices may have different addictive potential. However, few studies examine levels of nicotine dependence across devices among adolescent and young adult (AYA) e-cigarette users. To assess the extent of nicotine dependence among US AYA (ages 13-24) by e-cigarette device type, we conducted a large, national, cross-sect…
Sociodemographic Factors Associated with Adolescents’ and Young Adults’ Susceptibility, Use, and Intended Future Use of Different E-Cigarette Devices
Numerous studies have identified sociodemographic factors associated with susceptibility, ever-use and past-30-day use of e-cigarettes, including JUUL. However, it remains unknown which sociodemographic factors are associated with adolescents' and young adults' (AYA) use of the entire spectrum of different types of e-cigarette devices (e.g., disposables, pod/cartridge-based, and other e-cigarettes, like mods or tanks). The aim of this study was t…
Measures of both perceived general and specific risks and benefits differentially predict adolescent and young adult tobacco and marijuana use
Health behavior theorists and prevention researchers use a variety of measures of adolescent and young adult (AYA) risk and benefit perceptions to predict tobacco-use and marijuana-use behaviors. However, studies have not examined whether and how perception measures that ask about likelihood of more general outcomes such as “harm” versus ask about specific risk or benefit outcomes compare or whether they differentially predict AYA willingness to …
Development and Reach of the Stanford Tobacco Prevention Toolkit
BACKGROUND: We developed the Tobacco Prevention Toolkit (Toolkit) to enhance the impact of school-based tobacco education. This study describes the process of developing the Toolkit, its contents, and reach. METHODS: Qualitative community-based participatory research (CBPR), including focus group discussions (N = 152) and working groups with parents, educators, researchers, and youth (N = 87) were used to develop the Toolkit and design its implem…
Smokers Are More Likely to Smoke More after the Covid-19 California Lockdown Order
To determine if cigarette smoking, electronic cigarette use, and rate of consumption of these products differed before and after a pandemic lockdown order, two convenience samples of adults in Central California were recruited and surveyed before (March 2020) and after (May 2020) COVID-19 lockdown orders were implemented in California ( n = 2571). Multivariable logistic and negative binomial regression models tested the association between adults…
Sources of flavoured e-cigarettes among California youth and young adults
Although local laws may reduce access to flavoured e-cigarettes from retail sources, more comprehensive state or federal restrictions are recommended to close the loopholes for online sources. Dedicated efforts to curtail access from social sources are needed
The NIDDK High School Short-Term Research Experience for Underrepresented Persons
HS-STEP-UP has been highly successful in recruiting traditionally underrepresented students and supporting underrepresented HS students with a rewarding introductory experience to research. Students are overall satisfied with the program, but mentor matching needs more attention. Longer-term follow-up is needed to determine how participating in STEP UP impacts their decisions to participate in the biomedical workforce in the future
PMI’s heated tobacco products marketing claims of reduced risk and reduced exposure may entice youth to try and continue using these products
Importance Philip Morris International (PMI) is seeking Food and Drug Administration’s (FDA) authorisation to market IQOS as a modified risk tobacco product and to make marketing claims of reduced risk and reduced exposure. Such claims may be misunderstood by youth, thereby increasing their risk for tobacco initiation. Objective To assess youth (mean age 19.3, SD=1.7) understanding and perceptions of PMI’s proposed consumer marketing claims of re…
Oral Sex and Sexual Debut
Heated tobacco products likely appeal to adolescents and young adults
PMI's own data and available evidence from scientific studies conducted independent of the tobacco industry regarding how novel tobacco products are currently being marketed suggest that introduction of IQOS will result in adolescent and young adult non-users initiating tobacco use with IQOS and could also increase poly-use of IQOS along with other tobacco products
Iqos labelling will mislead consumers
Consumers will not understand the condition of the claims-that they must quit using cigarettes completely to achieve the inferred health benefits of IQOS. Rather, they are likely to misunderstand the unsupported claims of reduced risks to mean IQOS are harm-free
Adult Connection in Assault Injury Prevention among Male Youth in Low-Resource Urban Environments
A Longitudinal Study of Adolescents' Optimistic Bias about Risks and Benefits of Cigarette Smoking
Smoking-related optimistic bias in adolescents was not as prevalent as past studies showed. Anti-smoking interventions targeting adolescents should emphasize the risk of addiction and personal relevance of addiction
Conditional Risk Assessment of Adolescents' Electronic Cigarette Perceptions
Conditional risk assessment characterized adolescents' perceived e-cigarette risk/benefit profile, with potential utility for risk-perception measurement in future studies
Subjective Invulnerability and Perceptions of Tobacco-Related Benefits Predict Adolescent Smoking Behavior
Identifying factors that influence adolescents’ decisions to start smoking is necessary to improve interventions for reducing tobacco use. The current longitudinal study was designed to determine the direction of influence between feelings of invulnerability to harm and cigarette smoking, and to test whether the perceived risks and benefits of smoking mediate the relationship between invulnerability and smoking. Participants were 228 adolescents …
Experiences of community and parental violence among HIV-positive young racial/ethnic minority men who have sex with men
Adolescents and young adults (ages 13-24) in the USA are frequently exposed to violence in their community and home. While studies have examined the prevalence and impact of violence exposure among adolescents, there is a lack of data focusing specifically on adolescent men of color who have sex with men. Eight demonstration sites funded through a Special Projects of National Significance (SPNS) Initiative recruited 363 HIV-positive racial/ethnic…

The development of reproductive strategy in females
To test a proposition central to J. Belsky, L. Steinberg, and P. Draper's (1991) evolutionary theory of socialization-that pubertal maturation plays a role in linking early rearing experience with adolescent sexual risk taking (i.e., frequency of sexual behavior) and, perhaps, other risk taking (e.g., alcohol, drugs, delinquency)-the authors subjected longitudinal data on 433 White, 62 Black, and 31 Hispanic females to path analysis. Results show…
Judgments about Risk and Perceived Invulnerability in Adolescents and Young Adults
This study examined age differences in risk judgments and perceptions of invulnerability, by surveying 577 adolescents (grades 5, 7, and 9) and young adults (ages 20 to 30 years) for their judgments concerning natural hazards and behavior–linked risks. Adolescents were less likely than were young adults to see themselves as invulnerable, and only a small minority of adolescents evidenced such perceptions. Moreover, individuals’ perceptions about …
Greater Expectations
Adolescents view intimacy, sexual pleasure and social status as important goals in a relationship. Many have strong positive expectations that sex would satisfy these goals. Prevention programs and providers should address the risks of sex in the context of expected benefits
Initiating Sexual Experiences
Understanding how young adolescents make decisions to engage in early sexual activities is vital for intervention efforts aimed at fostering positive youth development and reducing the negative outcomes of adolescent sexual behavior. In‐depth interviews with 42 suburban, mostly White, ninth‐grade adolescents (52% females, mean age=14.1, SD =.45) elicited accounts of their early sexual decisions. We adapted grounded theory methodology to build a m…
Perceptions of Smoking-Related Risks and Benefits as Predictors of Adolescent Smoking Initiation
Objectives. The predictive value of perceptions of smoking-related risks and benefits with regard to adolescent smoking initiation has not been adequately established. We used prospective, longitudinal data to directly test whether smoking-related perceptions predict smoking initiation among adolescents. Methods. We administered surveys assessing perceptions of smoking-related risks and benefits to 395 high school students, beginning at the start…
Social and Emotional Consequences of Refraining From Sexual Activity Among Sexually Experienced and Inexperienced Youths in California
Objectives. We examined the social and emotional consequences among adolescents of refraining from sexual activity (oral or vaginal sex) and whether these consequences differed over time and by gender and sexual experience. Methods. Adolescents (N=612; 58% female) recruited from 2 schools were assessed at 4 time points separated by 6-month intervals, beginning in fall of ninth grade. Results. The percentage of adolescents who reported only positi…
Adolescents Discriminate between Types of Smokers and Related Risks
Many studies concerning cigarette smoking and smoking-related outcomes among adolescents use categories such as “casual” or “regular” smoker to define different types of smokers. It is not clear whether adolescents themselves differentiate between different types of smokers. The present study sought to examine whether and how adolescents discriminate between categories of smokers and how these discriminations engender different perceptions of ris…

Oral Versus Vaginal Sex Among Adolescents
Objective. Despite studies indicating that a significant proportion of adolescents are having oral sex, the focus of most empirical studies and intervention efforts concerning adolescent sexuality have focused on vaginal intercourse. This narrow focus has created a void in our understanding of adolescents' perceptions of oral sex. This study is the first to investigate adolescents' perceptions of the health, social, and emotional consequences ass…

Greater Expectations
CONTEXT: Effective STD and pregnancy prevention efforts should benefit from knowledge of what motivates adolescents to have sex. Positive motivations, and how they differ by gender and sexual experience, are poorly understood. METHODS: A sample of 637 ninth graders were asked about their relationship goals, expectations of the degree to which sex would satisfy these goals and sexual experience. Three scales measured adolescents' goals for intimac…
