Purpose: This article examines sociodemographic correlates of initiation and quitting among French and American smokers.
Methods: National surveys in France and the United States in 2000, 2005, and 2010 were analyzed of ever smokers, 20-75 years old. Bivariate and multivariate logistic regression analyses were conducted on age of initiation and quitting.
Purpose: Recent findings suggest a link between facultative melanin and nicotine dependence among African Americans. We hypothesized that tanning capacity is associated with the time to first cigarette (TTFC) of the day.
Methods: Using a criterion based sample of 150 adult African American current smokers, reflectometer measures of constitutive and facultative melanin, tanning capacity, smoking status and history, saliva cotinine, sociodemographic characteristics, and stress and discrimination scales were recorded.
Introduction: Sugars are major constituents and additives in traditional tobacco products, but little is known about their content or related toxins (formaldehyde, acetaldehyde, and acrolein) in electronic cigarette (e-cigarette) liquids. This study quantified levels of sugars and aldehydes in e-cigarette liquids across brands, flavors, and nicotine concentrations (n = 66).
Methods: Unheated e-cigarette liquids were analyzed using liquid chromatography mass spectrometry and enzymatic test kits.
Introduction: Prior to the US Food and Drug Administration's (FDA) regulation of electronic cigarettes and warning statements related to nicotine addiction, there was no critical examination of manufacturer/distributor voluntary practices that could potentially inform FDA actions aimed to protect consumers. This study examined the content of warning statements and safety characteristics of electronic cigarette liquid bottles using a national sample.
Methods: Research staff randomly selected four electronic cigarette liquid manufacturers/distributors from four US geographic regions.
