Vaping, or the use of electronic cigarettes (e-cigarettes), is an ongoing issue for public health. The rapid increase in e-cigarette usage, particularly among adolescents, has often been referred to as an epidemic. Drawing upon this epidemiological analogy between vaping and infectious diseases as a theoretical framework, we present a deterministic compartmental model of adolescent e-cigarette smoking which accounts for social influences on initiation, relapse, and cessation behaviours.
Ventral tegmental area (VTA) nicotinic acetylcholine receptors (nAChRs) are important for nicotine reinforcement. To determine whether and to what extent these receptors are sufficient for nicotine reinforcement, we expressed Beta2Leu9'Ser (i.e. sensitized) nAChR subunits in the VTA of adult male rats and assessed the nicotine dose-response relationship in intravenous self-administration (SA).
Background: E-cigarette use is now prevalent among adolescents and young adults, raising concerns over potential adverse long-term health effects. Although it is hypothesised that e-cigarettes promote inflammation, studies have yielded conflicting evidence. Our previous work showed that JUUL, a popular e-cigarette brand, elicited minimal lung inflammation but induced significant molecular changes in adult C57BL/6 mice.
Oral nicotine pouches are the latest products in the tobacco industry. They are manufactured by large tobacco companies and entice tobacco or nicotine addicts, although the products are presented as a 'harmless choice.' Nevertheless, dentists and oral health specialists worry about oral mucosal changes due to product interactions with the oral mucosa.
Introduction: Smoking is negatively related to mental health, but there is a paucity of research on the relationship between the use of smokeless tobacco, such as snus, and mental health outcomes, especially in people with alcohol use disorders (AUD). The aim of the present study was to examine the development of mental distress and quality of life (QoL) among AUD patients in treatment who did or did not use snus.
Introduction: Young adults are attempting to quit vaping, with many accessing smoking cessation programs with a lack of reported efficacy, highlighting the need for targeted vaping cessation support. Young people report seeing health professionals as potential sources of support in the quitting process. Additionally, the current changing regulatory landscape around vaping in Australia potentially increases numbers of those seeking health professional help for cessation.
2-naphthylamine (NAP) was classified as a group I carcinogen associated with bladder cancer. The daily exposure is mostly from cigarette and E-cigarette smoke. NAP can lead to testicular atrophy and interstitial tissue hyperplasia; however, the outcomes of NAP treatment on spermatogenesis and the associated mechanisms have not been reported.
E-liquids contain combinations of chemicals, with many enhancing the sensory attractiveness of the product. Studies are needed to understand and characterize e-liquid ingredients, particularly flavorings, to inform future research and regulations of these products.
