Introduction: Cigarettes and other tobacco products may be extinguished by submersion in liquids in beverage cans or bottles. Cases of nicotine poisoning in children have been reported following ingestion of such liquids. The aim of this study is to analyze the variability of nicotine concentrations with respect to number of cigarettes immersed and the duration of immersion in a soda can METHODS: One unsmoked cigarette was immersed in a cola containing soda can. Three separate samples of the mixture were obtained at different intervals of time post immersion up to 1 week. At the same time, a set of four cola cans were immersed with an increasing number of unsmoked cigarettes and samples obtained. All the samples were then analyzed for nicotine concentrations using liquid chromatography-mass spectrometry.
Results: The mean concentration of nicotine measured over the course of 6 hours from one full cigarette in 55 ml of a cola beverage was 0.48 mg/ml. Nicotine concentrations steadily increased in the first 6 hours following submersion, after which, the levels plateaued (r = 0.530, n = 18, p = 0.024). There was a strong positive correlation between nicotine concentrations and the number of cigarettes (r = 0.967, n = 12, p = 3e-7).
Conclusions: The mean concentration of nicotine measured over the course of 6 hours from one immersed cigarette can be potentially toxic especially to children. Nicotine concentrations are positively correlated with the number of cigarettes and time of immersion.

Introduction: Many tobacco smokers try to quit with electronic nicotine delivery systems (ENDS or e-cigarettes). We aimed to describe e-liquid flavors and nicotine concentration use over 6 months in a prospective cohort of smokers willing to quit with ENDS.
Methods: We included 622 participants from the intervention group of the Efficacy, Safety and Toxicology of ENDS randomized controlled trial.
Effect of electronic cigarette atomising power and flavour on aerosol size-segregated metal concentration and inhalation risk.

Introduction: Although numerous studies have estimated the inhalation dose of metals emitted from electronic cigarettes (e-cigs), the impact of factors including aerosol size and the atomising power of e-cig aerosols on estimating the inhalation dose of metals remains underexplored. A comprehensive understanding of these determinants is essential to assess the health risks associated with inhaling e-cig aerosols, which may contain potentially harmful metals.
Objectives: The aim of this study is to elucidate the mass and inhalation doses of potentially harmful metals in e-cig aerosols by different particle size and their association with the various atomising powers of e-cig devices and flavours.

Background: Hookah tobacco smoking is prevalent among youth and young adults. While health warning labels play a critical role in communicating the health risks of tobacco product use to consumers, compliance with US Federal Regulation's nicotine warning requirements on hookah tobacco packaging is low. Some labelling suggests that consumers are exposed to 'only 0.

Interventions for quitting vaping.

Department of Health Promotion and Policy, University of Massachusetts, Amherst, MA, USA.
Rationale: There is limited guidance on the best ways to stop using nicotine-containing vapes (otherwise known as e-cigarettes) and ensure long-term abstinence, whilst minimising the risk of tobacco smoking and other unintended consequences. Treatments could include pharmacological interventions, behavioural interventions, or both.
Objectives: To conduct a living systematic review assessing the benefits and harms of interventions to help people stop vaping compared to each other or to placebo or no intervention.
