Ventilation and features of the lung environment dynamically alter modeled intrapulmonary aerosol exposure from inhaled electronic cigarettes.
Sci Rep

Electronic cigarettes (e-cigs) fundamentally differ from tobacco cigarettes in their generation of liquid-based aerosols. Investigating how e-cig aerosols behave when inhaled into the dynamic environment of the lung is important for understanding vaping-related exposure and toxicity. A ventilated artificial lung model was developed to replicate the ventilatory and environmental features of the human lung and study their impact on the characteristics of inhaled e-cig aerosols from simulated vaping scenarios.

- Vaping among adolescents, particularly with fake devices, poses significant health risks, as highlighted by the 2019-2020 EVALI outbreak.
- Interviews with 47 California teens revealed their awareness of fake vaping products, which they viewed as low-quality and dangerous, learned about through peers and social media.
- Participants felt that the existence of these fake devices was driven by profit, calling for better public messaging and stronger regulations to protect young users.

Background: E-cigarette, or vaping products produce an aerosol by heating nicotine, or cannabis including tetrahydrocannabinol (THC) and cannabidiol (CBD), mixed with other chemicals that help make the aerosol. They are increasingly popular among teenagers and young adults, with a 2023 survey reporting that 2.13 million middle and high school students in the United States used e-cigarettes within the last 30 days.

Objective: Understanding the association between cannabis use and binge eating is of interest amidst growing global cannabis legalization. While preliminary research suggests a link between cannabis use and binge eating, population-based data among young adults, both female and male, are lacking. Given that depressive symptoms can act as an important precipitant of both cannabis use and binge eating, exploring the role of depressive symptoms is essential.

Article Synopsis
- - Tuberculosis (TB) risk may increase with cannabis use, particularly in the wake of its legalization in Thailand, prompting a study to analyze different cannabis consumption types and their impact on TB.
- - A matched case-control study in Songkhla Province revealed that TB cases had a lower socioeconomic status and higher frequencies of tobacco and alcohol use, with significant cannabis use observed among them compared to healthy controls.
- - The study found a notable odds ratio of 4.22 for the risk of TB from smoking and sharing bongs of cannabis, indicating that shared cannabis consumption could contribute to TB prevalence in lower-middle-income countries.
