The e‑cigarette has become increasingly popular in recent years. However, the question of toxicity is not yet clear and there is global uncertainty regarding the use of e‑cigarettes. This is intensified by the fact that there is a lack of declaration of the liquid ingredients.
Use of electronic cigarettes is rapidly increasing among youth and young adults, but little is known regarding the long-term cardiopulmonary health impacts of these nicotine-containing devices.
Youth and young adults with asthma use electronic cigarettes (e-cigarettes) at a higher rate than those without asthma. However, the factors that influence e-cigarette use in this vulnerable population are scarce. Therefore, the study aim was to assess the effects of anxiety, depression, impulsivity, and substance use in the relationship between e-cigarette use and youth and young adults with asthma status.
The objective of this study was to determine the association between e-cigarette use and depression and examine how this association is different by gender among US adults.
Inhalation of e-cigarette's aerosols (vaping) has the potential to disrupt pulmonary gas exchange, but the effects in asymptomatic users are unknown. We assessed ventilation-perfusion (V̇A/Q̇) mismatch in asymptomatic e-cigarette users, using magnetic resonance imaging (MRI). We hypothesized that vaping induces V̇A/Q̇ mismatch through alterations in both ventilation and perfusion distributions.
Electronic cigarettes are the most commonly used nicotine containing product among teenagers. The oral epithelium is the first site of exposure and our recent work revealed considerable diversity among e-liquids for composition and level of chemical constituents that impact nicotine deposition in a human oral-trachea cast and affect the formation of reactive carbonyls.
Although research remains somewhat equivocal, there is clear reason for concern regarding the potential oncogenicity of E-Cigarettes/E-Liquids with a strong basic and molecular science basis. Given lag times (extrapolating from tobacco smoke data) of perhaps 20 years, this may have significant future public health implications. Thus, the authors feel further study in this field is strongly warranted and consideration should be made for tighter control and regulation of these products.
Electronic cigarettes (e-cigarettes) are marketed as an alternative to smoking for those who want to decrease the health risks of tobacco.
