Parsing The Influences Of Nicotine And Expectancies On The Acute Effects Of E-Cigarettes: A Balanced-Placebo Experiment, Amanda M. Palmer

USF Tampa Graduate Theses and Dissertations

E-cigarette use has been increasing in recent years, and its ultimate public health impact is still unknown. In order to assess the addictive liability of these products, research is needed to investigate the roles of nicotine and other factors on psychological and physical effects of “vaping.” The goal of the current study was to investigate the role of expectancies, nicotine delivery, and their interactions on the effects of e-cigarette use via a balanced-placebo experiment. In this design, drug dosage (contains nicotine or not) was crossed with instructions (told nicotine or non-nicotine) during ad-lib e-cigarette use sessions by 128 current e-cigarette …

Motivation For Tobacco Cessation Among Nicotine Dependent Postmenopausal Females, Mackenzie Rae Peltier

LSU Doctoral Dissertations

Postmenopausal females continue to smoke despite considerable health risks related to low levels of estrogen in combination with antiestrogenic effects of nicotine. These females face barriers to cessation that are more severe than their male and pre-menopausal counterparts. These barriers include negative affect, weight concerns, and menopausal symptom severity. Brief motivation-based interventions (B-MIs) that incorporate individualized health-related feedback have demonstrated efficacy for smoking cessation, but have not been tested among postmenopausal females. The current study explored the effect of negative affect, weight concerns, and menopausal symptom severity on motivation and readiness to quit smoking, and the effectiveness of a B-MI …

The Impact Of Stress On Steroid Hormones And Cue Reactivity In Smokers And Gamblers, Stephanie Elaine Wemm

Legacy Theses & Dissertations (2009 - 2024)

Addictions, both substance and behavioral, have been conceptualized as having similar biopsychosocial processes with different opportunistic expressions (Shaffer et al., 2004). Biological processes such as the hormonal response to stress as measured by cortisol, dehydroepiandrosterone (DHEA), and the ratio of the DHEA/cortisol may be among the variables underlying the disposition to develop an addictive disorder, regardless of whether it is a substance-based or a so-called behavioral addiction. The current study aimed to examine whether physiological and psychological reactions to stress are similar in high-frequency smokers and gamblers. The subjective (urges, cravings) and physiological responses (skin conductance and heart rate) of …

Comparing The Effects Of Menthol Status On The Behavioral Pharmacology Of Smoking Reduced Nicotine Content Cigarettes, Danielle Davis

Graduate College Dissertations and Theses

Introduction: An active area of tobacco regulatory science research focuses on examining the effects of varying the nicotine content of cigarettes as part of a potential national policy to lower their nicotine content levels to reduce addiction potential. The present study examines differences in the behavioral effects of reduced nicotine content cigarettes related to their menthol status. Menthol is the only cigarette flavoring that is still legally permissible according to Food and Drug administration regulations.

Methods: Participants were 26 current adult smokers from three populations especially vulnerable to tobacco use and addiction (economically disadvantaged women, opioid-dependent individuals, individuals with affective …
