Introduction: Subjective experience of e-cigarettes may be an important factor in helping people who use combustible cigarettes switch completely to e-cigarettes to reduce harm from smoking. This paper describes a novel two-stage analysis using pleasure and satisfaction responses from ecological momentary assessments (EMA) of both cigarette and e-cigarette use to predict future cigarette and e-cigarette tobacco use.

Aims And Methods: This observational study included adult users of cigarettes and e-cigarettes who provided 7 days of EMA, capturing cigarette and e-cigarette use, followed by biweekly reports of cigarette and e-cigarette use over 1 year.

Objective: Waterpipe tobacco (WPT) use is common among reproductive age patients and is often perceived as safer than cigarette use. Prior studies have shown a decrease in nausea and vomiting symptoms among pregnant women who use cigarettes, but no studies to date have examined these symptoms in pregnant women who use WPT. This study was aimed to investigate the extent of symptoms of nausea/vomiting of pregnancy among participants who self-reported WPT use during pregnancy.

  • Maternal smoking is a key risk factor for low birth weight, and this study examines how the maternal nicotine metabolite ratio (NMR) affects the relationship between cigarette use during pregnancy and infant birth weight.
  • Researchers studied 454 pregnant women, focusing on the impact of their smoking habits and NMR on their babies’ weights, finding that slower NMR is linked to lower birth weights particularly for those smoking fewer than 15 cigarettes daily.
  • The study also highlighted that while Black women had slower NMRs, this factor affects birth weight similarly across both Black and white women, indicating a heightened risk of health issues for infants of mothers with slower nicotine metabolism.

Although tobacco (TOB) and marijuana (MJ) are often co-used in pregnancy, little is known regarding the joint impact of MJ + TOB on offspring development, including the developing neuroendocrine stress system. Further, despite evidence for sex-specific impacts of prenatal exposures in preclinical models, the sex-specific impact of prenatal MJ + TOB exposure on offspring neuroendocrine regulation in humans is also unknown. In the current study, overall and sex-specific influences of MJ + TOB co-use on offspring cortisol regulation were investigated over the first postnatal month.

Introduction: Despite the overall decline in the prevalence of cigarette use in the United States, menthol cigarette use among smokers is rising, and evidence shows that it may lead to more detrimental effects on public health than regular cigarette use. One of the mechanisms by which nicotine sustains tobacco use and dependence is due to its cognitive enhancing properties, and basic science literature suggests that menthol may also enhance nicotine's acute effect on cognition.

Aims And Methods: The purpose of this review is to suggest that the cognitive enhancing effects of menthol may be a potentially important neuropsychological mechanism that has yet to be examined.

Introduction: The degree to which smokers quit successfully with varenicline is strongly associated with their adherence to the medication regimen. Thus, measuring varenicline adherence to identify smokers needing additional intervention is a priority. Few studies, however, have examined the validity of self-reported varenicline adherence, using a biological assessment of adherence as a reference.
