Direct emissions of nicotine and harmful chemicals from electronic cigarettes (e-cigarettes) have been intensively studied, but secondhand and thirdhand e-cigarette aerosol (THA) exposures in indoor environments are understudied. ⋯ This study adds new convincing evidence that e-cigarette vaping can cause secondhand and THA exposures. Our findings can inform Occupational Safety and Health Administration, state authorities, and other government agencies regarding indoor air policies related to e-cigarette use, particularly in vape-shops. There is an urgent need to ensure that vape-shops maintain suitable ventilation systems and cleaning practices to protect customers, employees, and bystanders. Our study also demonstrates that nicotine can deposit or be adsorbed on baby's clothes and toys, and that tobacco-specific nitrosamines can form and retain on baby's clothes, highlighting children's exposure to environmental e-cigarette aerosol and THA at home is of a particular concern.

This study examined whether nontobacco flavors are more commonly used by vapers (e-cigarette users) compared with tobacco flavor, described which flavors are most popular, and tested whether flavors are associated with: vaping satisfaction relative to smoking, level of enjoyment with vaping, reasons for using e-cigarettes, and making an attempt to quit smoking by smokers. ⋯ Recent concerns about the attractiveness of e-cigarette flavors among youth have resulted in flavor restrictions in some jurisdictions of the United States and Canada. However, little is known about the possible consequences for current and former smokers if they no longer have access to their preferred flavors. This study shows that a variety of nontobacco flavors, especially fruit, are popular among adult vapers, particularly among those who have quit smoking and are now exclusively vaping. Limiting access to flavors may therefore reduce the appeal of e-cigarettes among adults who are trying to quit smoking or stay quit.

Minimum floor price laws (MFPLs) are an emerging tobacco control policy that sets a minimum price below which a specific tobacco product cannot be sold. MFPLs target cheaper products and may disproportionately impact consumers choosing low price brands or using discounts to reduce prices. We developed a static microsimulation model for California, United States to project short-term effects of different MFPL options for a 20-stick pack of cigarettes on adult smoking behaviors. ⋯ Despite reductions in adult smoking prevalence, significant socioeconomic disparities remain, with lower-income groups smoking at substantially higher levels than higher-income groups. Policies that set a floor price below which a tobacco product cannot be sold could reduce socioeconomic disparities in smoking, depending on variation in prices paid by smokers prepolicy. By using a microsimulation model to predict changes in smoking for different population groups in California under several floor price scenarios, this study demonstrates that MFPLs have the potential to reduce adult smoking prevalence overall, and especially for lower-income tobacco users.

Smoking Cessation in the ITALUNG Lung Cancer Screening: What Does "Teachable Moment" Mean?
Changes in smoking habits and predictors of smoking cessation were examined in the randomized ITALUNG lung cancer screening trial. ⋯ Participating in lung cancer screening promotes smoking cessation. An effective "teachable moment" may be achieved when the smoking cessation intervention is structured as integral part of the screening clinical visits and conducted by a dedicated team of health care professionals. Standardized guidelines for smoking cessation interventions in lung cancer screening are needed.

Randomized Controlled Trial
History and Correlates of Smoking Cessation Behaviors Among Smokers With Serious Mental Illness.
Individuals with serious mental illness (SMI) smoke at rates two to three times greater than the general population but are less likely to receive treatment. Increasing our understanding of correlates of smoking cessation behaviors in this group can guide intervention development. ⋯ Consideration of factors related to cessation behaviors among smokers with SMI continues to be warranted, due to their high smoking rates compared to the general population. Increasing our understanding of these predictive characteristics can help promote higher engagement in evidence-based smoking cessation treatments among this subpopulation.
