Studies testing novel tobacco products often provide participants with free product and assess consumption. Some, but not all, studies find that providing free cigarettes increases smoking. We tested changes in smoking when free cigarettes were provided to nondaily, intermittent smokers, who constitute one-third of US adult smokers. ⋯ The study shows that providing nondaily smokers with free cigarettes increases cigarette consumption, but does differentially for different subgroups and cigarette types, while also decreasing smoking intensity. This suggests the value of using free-cigarette baseline data in studies where interventions provide free cigarettes.

Comparative Study
Examining Daily Electronic Cigarette Puff Topography Among Established and Nonestablished Cigarette Smokers in their Natural Environment.
Understanding exposures and potential health effects of e-cigarettes is complex. Users' puffing behavior, or topography, affects function of e-cigarette devices (eg, coil temperature) and composition of their emissions. Users with different topographies are likely exposed to different amounts of any harmful or potentially harmful constituents (HPHCs). In this study, we compare e-cigarette topographies of established cigarette smokers and nonestablished cigarette smokers. ⋯ A user's topography affects his or her exposure to HPHCs. As this study demonstrates, user characteristics, such as level of smoking, can influence topography. Thus, it is crucial to understand the topography profiles of different user types to assess the potential for population harm and to identify potentially vulnerable populations. This study only looked at topography of cigarette smokers using disposable e-cigarettes. Further research is needed to better understand potential variation in e-cigarette topography and resulting exposures to HPHCs among users of different e-cigarette devices and liquids.

Comparative Study
Smoking Among Hispanic/Latino Nationality Groups and Whites, Comparisons Between California and the United States.
Although California is home to the largest Hispanic/Latino population, few studies have compared smoking behavior trends of Hispanic/Latino nationality groups in California to the remaining United States, which may identify the impact of the states antitobacco efforts on these groups. This study compared smoking status, frequency, and intensity among Mexican Americans, Central/South Americans, and non-Hispanic Whites in California to the remaining United States in the 1990s and 2000s. ⋯ The present study explored the differences in smoking behaviors between Whites, Mexican Americans, and Central South/Americans living in California versus the rest of the United States in the 1990s and the 2000s. The results contribute to our current knowledge as there have been minimal efforts to provide disaggregated cigarette consumption information among Hispanic/Latino nationality groups. Additionally, by comparing cigarette consumption between those in California and the remaining United States, our data may provide insight into the impact of California's antitobacco efforts in reaching Hispanic/Latino subpopulations relative to the remaining US states, many of which have had less tobacco control policy implementation.

Cigarette smoking has decreased to a record low among youth across the United States, including in Virginia. Rates of alternative tobacco use, however, are rising and polytobacco use is common. A better understanding of the shifting use patterns and associated risk factors is important for informing tobacco prevention, cessation, and policy efforts. ⋯ These findings suggest distinct patterns of current tobacco use, including a high proportion of youth engaging in polytobacco use. Heavy polytobacco use co-occurs with other health risk behaviors and may be attributed to psychosocial risk factors. Results underscore the need for detailed monitoring of shifting youth tobacco use patterns as well as targeted prevention, cessation, and policy efforts.

The tobacco product landscape has changed substantially. Little is known about the recent pattern of polytobacco use (at least two tobacco products) among US adults and its relationship to nicotine dependence. ⋯ This study examines recent patterns of polytobacco use separately for US adult current cigarette smokers, cigar smokers, pipe smokers, hookah users, e-cigarette users, and smokeless tobacco users. By including more tobacco products, particularly e-cigarettes and hookah, this study provides more comprehensive insight into polytobacco use. This study is also unique in comparing nicotine dependence between polytobacco and sole-product users among each category of tobacco users. Our results indicate that polytobacco use is very common and is associated with greater likelihood of reporting nicotine dependence symptoms. Tobacco cessation policies and programs should be tailored to address polytobacco use.
