E-cigarettes and asthma in adolescents.

Introduction:
This text provides an analysis of the relationship between e-cigarette use and asthma in adolescents. It highlights recent studies and trends related to e-cigarette use, pulmonary toxicity of e-cigarettes, and e-cigarette screening and cessation.

Key Points:

* E-cigarettes have been the most popular tobacco product used by adolescents since 2014.
* adolescents with asthma are more likely to be e-cigarette users than those without asthma and more likely to have asthma exacerbations.
* E-cigarette use has been linked to both future combustible cigarette use and illicit drug use.
* The FDa has worked to limit exposure to youth by restricting flavored vaping products, but youth continue to be a target of tobacco company market strategies.
* Trends in e-cigarette use in adolescents have increased in recent years, despite regulatory efforts.
* E-cigarette aerosol has been found to contain toxins that are pro-inflammatory and cytotoxic to respiratory epithelium.
* Studies have shown that e-cigarette use is more common among youth with asthma and is associated with increased inflammation and lung damage.
* Despite existing smoking cessation guidance, pediatric practitioners are not likely to provide cessation counseling for adolescents who use e-cigarettes, and screening youth for e-cigarette use is important.

Main Message:
The text emphasizes the importance of understanding the relationship between e-cigarette use and asthma in adolescents. It highlights the need for pediatric practitioners to provide cessation counseling for adolescents who use e-cigarettes and the importance of screening youth for e-cigarette use. The text also underscores the need for further research on e-cigarette cessation, as existing guidelines are lacking. Ultimately, the text emphasizes the need for regulatory efforts to limit youth exposure to e-cigarettes and protect their health.
