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.

Despite progress in limiting exposure to secondhand smoke (SHS) in the United States, little is known about the impact of smoke-free polices in prisons and jails. SHS exposure in this setting may be great, as smoking prevalence among inmates is more than three times higher than among non-incarcerated adults. To inform the implementation of smoke-free policies, this article reviews the literature on the extent, nature, and impact of smoke-free policies in U.S. prisons and jails. ⋯ Smoke-free policies have become increasingly common in prisons and jails, but evidence suggests they are not consistently implemented. Future studies should examine the health and economic outcomes of smoke-free policies in prisons and jails. By implementing smoke-free policies, prisons and jails have an opportunity to improve the health of staff and inmates.

Randomized Controlled Trial
Efficacy of a tobacco quitline among adult survivors of childhood cancer.
The purpose of this investigation was to determine the efficacy of two evidence-based tobacco quitlines in adult survivors of childhood cancer who regularly smoke cigarettes. ⋯ Our results indicate that neither a Proactive + 4 weeks of medication or Reactive + 2 weeks of medication quitline significantly impacted long-term smoking cessation rates. Our results further indicate that self-reports of smoking status are unreliable in survivors of childhood cancer, a population in considerable need of tobacco abstinence. Rates of smoking cessation may be markedly overestimated in studies of childhood cancer survivors that rely on self-reports of tobacco abstinence, and future studies need to include biochemical verification of tobacco status in this population.

Multicenter Study
Cigarette Smoking and Depressive Symptoms Among Hispanic/Latino Adults: Results From the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).
In the present study, we investigated associations among cigarette smoking, smoking cessation treatment, and depressive symptoms in Hispanic/Latino adults. ⋯ In conclusion, these findings suggest that the positive association between smoking status and depressive symptoms is present in all examined Hispanic/Latino background groups.

In the United States, electronic cigarettes (e-cigarettes) are currently unregulated, extensively marketed, and experiencing a rapid increase in use. The purpose of this study was to examine the opinions of U.S. adults about e-cigarette use in smoke-free public areas. ⋯ Over 75% of U.S. adults reported uncertainty or disapproval of the use of e-cigarettes in smoke-free areas. Current cigarette smokers, adults aware or have ever used e-cigarettes were more supportive to exempting e-cigarettes from smoking restrictions. With impending regulation and the changing e-cigarette landscape, continued monitoring and research on public opinions about e-cigarette use in smoke-free places are needed.
