The Effect of Pack Warning Labels on Quitting and Related Thoughts and Behaviors in a National Cohort of Aboriginal and Torres Strait Islander Smokers.
The high prevalence of smoking among Aboriginal and Torres Strait Islander people in Australia (39%) contributes substantially to health inequalities. This study assesses the impact of warning labels on quitting and related thoughts and behaviors for Aboriginal and Torres Strait Islander smokers. ⋯ Graphic warning labels are likely to be effective for Aboriginal and Torres Strait Islander smokers as they are for the broader Australian population.

Cigarette Graphic Warning Labels Are Not Created Equal: They Can Increase or Decrease Smokers' Quit Intentions Relative to Text-Only Warnings.
Cigarette graphic-warning labels elicit negative emotion. Research suggests negative emotion drives greater risk perceptions and quit intentions through multiple processes. The present research compares text-only warning effectiveness to that of graphic warnings eliciting more or less negative emotion. ⋯ This research is the first to directly manipulate two emotion levels in sets of nine cigarette graphic warning images and compare them with text-only warnings. Among adult and teen smokers, high-emotion graphic warnings were associated with increased risk perceptions and quit intentions versus text-only warnings. Low-emotion graphic warnings backfired and tended to reduce risk perceptions and quit intentions versus text-only warnings. Policy makers should be aware that merely placing images on cigarette packaging is insufficient to increase smokers' risk perceptions and quit intentions. Low-emotion graphic warnings will not necessarily produce desired population-level benefits relative to text-only or high-emotion warnings.

An Electronic Cigarette Vaping Machine for the Characterization of Aerosol Delivery and Composition.
Characterization of aerosols generated by electronic cigarettes (e-cigarettes) is one method used to evaluate the safety of e-cigarettes. While some researchers have modified smoking machines for e-cigarette aerosol generation, these machines are either not readily available, not automated for e-cigarette testing or have not been adequately described. The objective of this study was to build an e-cigarette vaping machine that can be used to test, under standard conditions, e-liquid aerosolization and nicotine and toxicant delivery. ⋯ This study describes an electronic cigarette vaping machine that was assembled from commercially available parts. The vaping machine can be replicated by researchers and used under standard conditions to generate e-cigarette aerosols and characterize nicotine and toxicant delivery.

Many carbonyls are produced from the combustion of tobacco products and many of these carbonyls are harmful or potentially harmful constituents of mainstream cigarette smoke. One carbonyl of particular interest is acrolein, which is formed from the incomplete combustion of organic matter and the most significant contributor to non-cancer respiratory effects from cigarette smoke. Sheet-wrapped cigars, also known as "little cigars," are a type of tobacco products that have not been extensively investigated in literature. ⋯ This article reports on the measured quantity of acrolein from 15 commercial sheet-wrapped cigars using a validated standard smoking test method that derivatizes acrolein in the mainstream smoke with DNPH solution, and uses Liquid Chromatography/Ultra-Violet Detection (LC/UV) for separation and detection. These acrolein yields were similar to the levels found in the smoke from 35 commercial cigarette products measured in the same manner. Although sheet-wrapped cigar data were slightly more variable than those found for the cigarette data, this article reports that the production of acrolein is similar to cigarettes. The results demonstrate that sheet-wrapped cigars can be tested for acrolein yields in mainstream smoke using the same methods used for the evaluation of cigarettes.

Policies to promote smoking cessation among Medicaid-insured pregnant women have the potential to assist a significant proportion of pregnant smokers. In 2010, Kansas Medicaid began covering smoking cessation counseling for pregnant smokers. Our aim was to evaluate the use of smoking cessation benefits provided to pregnant women as a result of the Kansas Medicaid policy change that provided reimbursement for physician-provided smoking cessation counseling. ⋯ This study evaluates the use of Medicaid reimbursement for smoking cessation counseling among low-income pregnant women in Kansas. We describe the Medicaid claims rates of physician-provided smoking cessation counseling for pregnant women, an evidence-based and universally recommended treatment approach for smoking cessation in this population. Our findings show that claims rates for smoking cessation benefits in this population are very low, even after policy changes to support provision of cessation assistance were implemented. Additional studies are needed to determine whether reimbursement is functioning as intended and identify potential gaps between policy and implementation of evidence-based smoking cessation treatment.
