The Family Smoking Prevention and Tobacco Control Act requires new pictorial warnings for U.S. cigarette packs, but enactment has been delayed by tobacco industry lawsuits. Research can inform implementation of the pictorial warning requirement and identify ways to optimize their public health impact post-implementation. This study investigated the impact of warning label message framing on young smokers' motivation to quit, examining cessation self-efficacy, and perceived risks as moderators of message framing impact. ⋯ A combination of pictorial warnings featuring risk-based (i.e., loss-framed) and efficacy-enhancing (i.e., gain-framed) information may promote better public health outcomes. Research is needed to investigate how strategically framed warning messages impact smokers' behaviors based on their pre-existing attitudes and beliefs in real-world settings.

Graphic warning labels have been shown to be more effective than text-only labels in increasing attention and perceived health risks, but most U.S. studies have involved single exposures in laboratory or Internet settings. ⋯ U.S. smokers' reactions to graphic warning labels on their own packs were similar to other, more controlled studies. Qualitative findings underscore the need for warning labels that encourage self-referential processing without increasing defensive reactions.

Time to the first cigarette after waking up in the morning is the most validated measure of dependence among smokers, and its complement is also a good indicator of dependence for smokeless tobacco (ST) users. However, no studies have directly compared these measures. ⋯ Compared to light smokers, the likelihood of TTFU within 5min was similar among exclusive ST users and was slightly higher among ST former smokers, offering some support for the Fagerström-Eissenberg hypothesis that the dependence level of cigarettes is higher than that of ST.

Tobacco smoke contains more than 7,000 chemicals, including known carcinogens, such as tobacco-specific nitrosamines (TSNAs). TSNA levels in cigarettes vary considerably within and across markets; however, the extent to which these different TSNA levels translate into differences in human exposure and risk remains unclear. The current study sought to examine TSNA exposure among Canadian tobacco users. ⋯ The study findings provide the first nationally representative characterization of TSNA exposure among Canadian tobacco users. Although the findings indicate marked differences in TSNA exposure between Canadian and American populations of tobacco users, it is not known whether these differences in exposure translate into differences in risk.
