Youth vaping is a serious public health concern, being more prevalent than any other tobacco use. To inform cessation interventions, we explored what adolescents perceive as their reasons for quitting...
Semi-structured interviews were conducted with a convenience sample of 11 adolescents reporting vaping in the past 90 days and recruited from a high school in Massachusetts. Interviews were transcribe...
Reasons adolescents reported for quitting included cost, experiencing "nic-sick" from nicotine withdrawal or excess intake, negative impacts on mood, concentration, or health, and experiencing symptom...
Many adolescents who vape want to quit, and most have tried multiple times. Interventions need to engage adolescents with varying reasons to quit, barriers, and quit strategy preferences....
This study is registered through ClinicalTrials.gov. The trial registration number is NCT05140915. The trial registration date is 11/18/2021....
Widespread uptake of vaping has signaled a sea change in the future of nicotine consumption. Vaping has grown in popularity over the past decade, in part propelled by innovations in vape pen design an...
Background: Electronic delivery systems (e.g., vapes, e-cigarettes) are now popular modes of cannabis and nicotine administration that are often used by the same individuals; however, we still know li...
Polysubstance use, which increases the risk for negative consequences of substance use, is common among emerging adults who regularly consume substances by vaping. Examining predictors of polysubstanc...
The current study aimed to examine whether modifiable cognitive risk factors for increased vaping in the form of attitudes, expectancies and norms can predict co-use of nicotine and cannabis among vap...
Regular nicotine and cannabis vapers between 18 and 30 years were recruited online in Canada via a Qualtrics panel. Hierarchical binary logistic regression was used to predict membership in a polysubs...
Attitudes, expectancies and norms predicted polysubstance use over and above the effect of demographics, personality risk factors and anxiety, depression symptoms. Positive expectancies played a uniqu...
Cognitive interventions targeting attitudes, expectancies and norms may be effective in prevention of polysubstance vaping, although positive expectancies appear to be the main unique factor that has ...

Students with under seven sleep hours on school nights (OR = 2.6; 95% CI = 2.1-3.3) and who vaped in the past month (OR = 3.0; 95% CI = 2.1-3.9) had higher odds of attempting suicide in the last year....
Students who vape or report low sleep quantity would be ideal participants in suicide prevention interventions as they may be at higher risk for suicidality. Organizations implementing sleep or vaping...
Despite copious information on the hazards of nicotine and cannabis, many adolescents report vaping nicotine and cannabis. To advance knowledge on the precursors of vaping behaviors, this study examin...
Data were part of a longitudinal survey on substance use and mental health among adolescents and included 2,467 11th grade students from 10 public high schools in California. Participants completed a ...
Bivariate analyses showed participants who vaped nicotine had significantly higher drive and fun-seeking scores (p < 0.05); and cannabis vapers had lower BIS and reward responsiveness scores (p < 0.05...
Different behavioral motivations should be targeted when developing interventions designed to reduce nicotine and cannabis vaping among diverse adolescents....
In this paper, we provide a descriptive overview of how vaping is framed differently between various online platforms (Wikipedia, Quora, Medium, Reddit, Stack Exchange, wikiHow, Facebook, and online n...
Drawing on a 2-year study, I argue that the UK vape industry is engaged in a classificatory struggle between a subcultural industry and its "other", the mainstream industry. I build on Thornton's anal...
Electronic cigarettes are the most commonly used tobacco products by young adults. Measures of beliefs about outcomes of use (i.e., expectancies) can be helpful in predicting use, as well as informing...
We surveyed young adult students (N = 2296, Mean age=20.0, SD=1.8, 64 % female, 34 % White) from a community college, a historically black university, and a state university. Students answered ENDS ex...
A 5-factor solution [Positive Reinforcement (consists of Stimulation, Sensorimotor, and Taste subthemes, α = .92), Negative Consequences (Health Risks and Stigma, α = .94), Negative Affect Reduction (...
A novel ENDS expectancy measure appears to be a reliable measure for young adults with promising results in the domains of concurrent validity, incremental validity, and IRT characteristics. This tool...
Findings provide support for the future development of computerized adaptive testing of vaping beliefs. Expectancies appear to play a role in vaping similar to smoking and other substance use. Public ...
The e-cigarette or vaping product-use-associated lung injury (EVALI) epidemic was primarily associated with the use of e-cigarettes containing tetrahydrocannabinol (THC)- the principal psychoactive su...
