Prospective association of tobacco retailer density and neighbourhood walkability with youth vaping initiation in California, USA.

Background: Tobacco retailer density might influence youth e-cigarette use due to increased access and exposure to point-of-sale marketing. There is a need for longitudinal investigations on the association of tobacco retailer density with youth e-cigarette use, with consideration of contextual factors such as neighbourhood walkability that could enhance retailer exposure.

Methods: Five semi-annual waves (Fall 2021-Fall 2023) of a Southern California school-based cohort of youth who never vaped at baseline (n=3401; mean baseline age=15 years [range=12-17]) were merged with spatial data on tobacco retailers corresponding to each school year.

Appeal and Sensory Characteristics of Oral Nicotine Products in Young Adults Who Vape E-Cigarettes.

Introduction: This study applied a novel tobacco regulatory science paradigm to characterize inter-product variation in the appeal and sensory features of emerging commercial and therapeutic oral nicotine products (ONPs) among young adults that vape e-cigarettes.

Methods: Twenty-three young adults without ONP experience who use e-cigarettes completed a single-blind, single-visit remote lab study. Participants rated appeal and sensory characteristics during 5-minute standardized self-administrations of 8 ONPs (4 fruit, 4 mint) from various brands (Lucy, Rouge, Solace, Nicorette, On!, Velo).
