These results suggest that although current e-cigarette use decreased during 2019 to 2020, overall prevalence, frequent use, and flavored e-cigarette use remained high. Continued actions are warranted to prevent and reduce e-cigarette use among US youth.
ECIG use has increased among non-smokers, with the potential negative consequence of developing nicotine dependence. ECIG users report withdrawal symptoms upon abstinence, though the significance of these symptoms has been questioned. This preliminary study aimed to characterize the early timecourse of ECIG withdrawal under forced abstinence.
Growing demand of Juul and other electronic cigarettes, despite critical knowledge gaps about their chemical composition, has led to concerns regarding their potential health effects. We introduce a novel analytical approach, runtime cavity ringdown spectroscopy (rtCRDS) for rapid detection of oxidative products in e-cigarette aerosols, to facilitate the study of aerosol from a single puff of e-liquid.
These preliminary results suggest that both genes and environmental influences are potential drivers of EC initiation among adolescents and young adults.
The study was associated with reasonable recruitment and retention rates and promising acceptability in the electronic cigarette arm. Data required for full cost-effectiveness evaluation in the electronic cigarette arm could be collected, but some data were not available in the usual-care arm.
Electronic-cigarette use, or vaping, among youth has increased substantially in recent years. Tobacco smoking shows a strong association with other risk behaviors, but the association between vaping and other risk behaviors has rarely been explored. We examine the relationship between youth vaping and substance use, risky driving behaviors, and lack of bicycle helmet use.
The use of cannabidiol (CBD) in electronic cigarettes is widespread. Previously, it was reported that CBD is partly transformed to THC in case smoking as a cigarette, however, the pyrolysis of this compound has not been assessed extensively. The aim of our study was to investigate the effect of temperature on the composition of pyrolysis products of CBD.
Adolescent vaping is rapidly rising in Canada, and e-cigarettes have become the most widely used tobacco product among high school students; 29% of students in grades 10 to 12 reported e-cigarette use in 2019. Vaping among adolescents is a problem because the long-term health consequences of e-cigarettes remain unknown, large numbers of teens are becoming addicted to the harmful drug nicotine, and vaping has been shown to increase risk of initiation of combustible tobacco product use.
