Cannabis vaping elicits transcriptomic and metabolomic changes in inflammatory, oxidative stress and cancer pathways in human bronchial epithelial cells.

The increasing shift from cannabis smoking to cannabis vaping is largely driven by the perception that vaping to form an aerosol represents a safer alternative to smoking and is a form of consumption appealing to youth. Herein, we compared the chemical composition and receptor-mediated activity of cannabis smoke extract (CaSE) to cannabis vaping extract (CaVE) along with the biological response in human bronchial epithelial cells. Chemical analysis using HPLC and GC/MS revealed that cannabis vaping aerosol contained fewer toxicants than smoke; CaSE and CaVE contained teratogens, carcinogens, and respiratory toxicants.

Recent studies have suggested an evolving understanding of the association between vaping, specifically electronic cigarette (e-cigarette) use, and the progression of atherosclerosis, a significant contributor to cardiovascular disease. Despite the prevailing perception of vaping as a safer alternative to traditional tobacco smoking, accumulating evidence suggests that the aerosols emitted by e-cigarettes contain harmful constituents that may promote endothelial dysfunction, oxidative stress, inflammation, and dyslipidemia-key mechanisms implicated in atherosclerosis pathogenesis. While past research, including experimental studies and clinical investigations, has shed light on the potential cardiovascular risks associated with vaping, gaps in knowledge persist.

Elevated bioavailability of nicotine in vape aerosol together with known risks of nicotine exposure may result in previously uncharacterized cardiovascular consequences of vaping. The objective of this study is to assess the impact of nicotine exposure via vape aerosol inhalation upon myocardial response to infarction injury.

Introduction: Periodontal ligament-derived mesenchymal stem cells (PDL-MSCs) are promising cells with crucial roles in maintaining and repairing periodontal tissue. However, their regenerative capacity can be influenced by various factors, including cigarette smoke and electronic nicotine delivery system (ENDS) aerosols. Smoking and vaping can impair their regenerative potential, and even though ENDS are perceived as safer tobacco products, there is a lack of evidence to guarantee this assumption.

The harms of combustible cigarette (CC) use in pregnancy for fetal development are well studied. Less understood are the potential impacts of newer non-combustible cigarette alternatives, including electronic cigarettes (ECs). Our goal was to examine whether EC use during pregnancy predicts increased risk of adverse birth outcomes.
