SU was less common in AYA with chronic kidney disease than the general population, but differences were attenuated among those greater than or equal to 18 years. Ages 12-14 appear to be the ideal time for prevention efforts. As the landscape of e-cigarette and marijuana policies change, these results underscore the need to understand how similar high-risk populations engage in SU.
In this study, we reported marked disparities in the increase of youth e-cigarette use, with a larger recent increase in rural than in urban areas. T21 policies appear to mitigate these increases in both rural and urban youth.
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.
Given the health consequences of smoking and vaping and their association with high-energy drink and coffee consumption, policy initiatives to prevent smoking/vaping initiation, and to limit youth access to these beverages, warrant consideration.
An analysis of reports to the United Kingdom's Medicines and Healthcare products Regulatory Agency by manufacturers of vaping products shows that (i) these products have a large range of ingredients and emissions, (ii) the reporting system is unstandardized in terms of reporting requirements, and (iii) for quantified emissions, median levels are for the most part below published safe limits for ambient air.
Prevalence of e-cigarettes among Chinese adults had increased since 2015, especially among young people aged 15-24. The high level of dual use and lower quit rate among e-cigarette users indicated e-cigarettes had not shown cessation utility at the population level in China. Regulation of e-cigarettes is needed to protect youth and minimise health risks.
In the United States, some states and localities have added vaping restrictions to established smoke-free indoor air laws in order to reduce electronic cigarette use. Yet, if smokers use e-cigarettes to quit, such restrictions could have the unintended effect of attenuating the original smoke-free air policy's effects on smoking. This study estimated changes in current smoking, past-year smoking cessation, and recent vaping following the introduction of smoke- and vape-free air laws.
Ahead of any Food & Drug Administration (FDA) authorization for MRTP claims, some smokers already perceive exposure to "less harmful" claims for e-cigarettes, but few do for SLT. MRTP claims may motivate some smokers to use these products.
