BACKGROUND AND OBJECTIVES Flavored non-tobacco oral nicotine products (eg, pouches and nontherapeutic gum, lozenges, tablets, gummies), are increasingly marketed in the United States. Prevalence of product use among adolescents is unknown. METHODS We calculated prevalence ever past 6-month pouches, other (ie, and/or e-cigarettes, cigarettes, hookah or waterpipe, cigars, cigarillos, snus high school students Southern California between September December 2021. Generalized linear mixed models...
Disposable electronic cigarettes (e-cigarettes) are widely used by adolescents and young adults (AYAs). Whether using disposable devices is associated with future e-cigarette use patterns unknown but important for informing regulation.
OBJECTIVE. The purpose of our study was to describe the radiographic and CT findings in patients with pulmonary infections caused by Mycobacterium abscessus, one more common rapidly growing nontuberculous mycobacteria that cause lung disease.
Objectives Various organic acids are used to create nicotine salt formulations, which may improve the appeal and sensory experience of vaping electronic cigarettes (e-cigarettes). This clinical experiment examined effects partially highly protonated forms two formulations (nicotine lactate benzoate) versus free-base (no acid additive) on attributes e-cigarettes. Methods Current adult tobacco product users (n=116) participated in an online remote double-blind within-subject randomised...
This cross-sectional study investigates rates of nicotine concentrations vaped by US youths and associated substance use characteristics.
Background: Prior studies examining the association of cannabis use with nicotine abstinence did not distinguish between individuals co-using and versus those who switched from to exclusive use; these may have different effects on abstinence. We examined associations uptake subsequent approximately 1 year later among adults using cigarettes and/or e-cigarettes. Methods: Using six waves Population Assessment Tobacco Health Study (2013–2021), we assessed transitions pre-baseline (time t ) (1)...
This exploratory study aimed to describe longitudinal patterns of e-cigarette use initiation and progression frequent across mid-to-late adolescence young adulthood determine risk factors for consequences these patterns. Using 12 waves a prospective cohort data 2014-2023, we identified latent classes with distinct timing (20 + days/month). We then estimated: (1) associations baseline membership in (2) e-cigarette/other substance frequency dependence at subsequent 1-year follow-up. Southern...
Background This clinical experiment tested the effects of exposure to e-cigarettes with WS-23 or menthol cooling additives on user appeal and sensory attributes, and, secondarily, whether generalised across base characterising flavour, nicotine concentration, nicotine/tobacco product use status. Methods In this within-participant double-blind experiment, adult tobacco/nicotine users administered standardised puffs 18 different e-cigarette solutions in randomised sequences using a pod-style...

Modern oral nicotine products (ONPs; nontherapeutic pouches, gums, lozenges, and gummies) may be perceived in ways that could promote uptake nonvapers, dual use with e-cigarettes, or to quit vaping. In this cross-sectional digital remote survey of 1,460 respondents aged 21-24 from Southern California, we examined beliefs about ONPs among past-30-day e-cigarette nonusers, users unmotivated vaping, motivated Positive were reported by 31.8% the overall sample higher (with without motivation)...
The purpose of our study was to assess the rates and CT patterns locoregional recurrence after resection surgery lung cancers according histopathology tumor staging. Three hundred seventy nine patients who underwent due cancer in a recent 6 year period were followed up with (at 3, 6, 12, 18, 24 months, then annually surgery) for evaluation (analysis hilar or mediastinal lymph nodes surgical margin including bronchial stump, pleura, chest wall). compared terms underlying Of 379 patients, 75...
Objective This study examined the mediated pathways from e-cigarette use to internalizing and externalizing mental health via polysubstance among young adults.
This study applied a novel tobacco regulatory science paradigm to characterize inter-product variation in the appeal and sensory features of emerging commercial therapeutic oral nicotine products (ONPs) among young adults that vape e-cigarettes.
Most extant evidence has addressed between-person differences, short-term or cross-sectional associations of electronic nicotine delivery systems (ENDS) use with other substance use, the majority focusing on current rather than escalated use. The present study aimed to examine within-person changes in ENDS and their individual combined over a 6-year period.
