Mitochondrial abnormalities in lung epithelial cells have been associated with chronic obstructive pulmonary disease (COPD) pathogenesis. Cigarette smoke (CS) can induce alterations in the molecular pathways regulating mitochondrial function in lung epithelial cells.
Background: Previous research has investigated the association between attachment styles and smoking behaviors, indicating a positive association of insecure attachment styles with nicotine dependence. However, these links were mostly explored in adolescent and student samples. Moreover, the explanatory mechanisms and the variables influencing the strength of this relationship remained understudied.
Introduction: The purpose of this study is to culturally adapt the Awareness and Beliefs about Cancer (ABC) measure for use in the Hispanic/Latino population living in the United States (US).
Background: E-cigarettes are the most-used tobacco product among US adolescents and are associated with nicotine addiction. This qualitative investigation aimed to understand adolescents' experiences and perceptions with nicotine addiction, and related influences of addiction, to inform product regulation, health communication, and cessation resource development.
Objective: This pre-registered analysis aimed to examine the moderating role of nicotine-use motives on the association between minority stress and nicotine use and craving among sexual minority youth.
Nicotine, an addictive compound found in tobacco, functions as an agonist of nicotinic acetylcholine receptors (nAChRs) in the brain. Interestingly, nicotine has been reported to act as a cognitive enhancer in both human subjects and experimental animals. However, its effects in animal studies have not always been consistent, and sex differences have been identified in the effects of nicotine on several behaviors.
Background: Perceptions of health harms and addictiveness related to nicotine products, THC e-cigarettes, and e-cigarettes with other ingredients are an important predictor of use. This study examined differences in perceived harm and addiction across such products among adolescents, young adults, and adults.
Background: Ireland's Smoking Ban reduced health inequalities known to be associated with smoking but some groups may not have benefitted. Mental ill-health and smoking are known to be associated with health inequalities. Whether similar patterns exist for e-cigarette use is less clear, as few data exist.
