assessment of Nicotine and Cannabis Vaping and Respiratory Symptoms in Young adults.

Introduction:
This text provides an analysis of the relationship between nicotine and cannabis vaping and respiratory symptoms in young adults. It presents the findings of a cross-sectional study of 2553 young adults, which investigates the association between vaping and bronchitic symptoms, wheeze, and shortness of breath. The study also considers the impact of cigarette smoking and combustible cannabis use on these respiratory symptoms.

Key Points:

* The study is based on data from the happiness and health Study, a sample of young adults originally recruited from high schools throughout Southern California.
* The study uses a 5-level categorical variable to measure level of nicotine and cannabis vaping, based on responses to questions about the use of e-cigarettes, JUUL or similar devices, other electronic vaping devices, electronic devices to vape ThC or hash oil/dabs, cigarettes, smoking marijuana, and blunts.
* The study measures three respiratory outcomes: bronchitic symptoms, wheeze, and shortness of breath.
* The study controls for sociodemographic characteristics, cigarette smoking, and combustible cannabis use in its analysis.
* The study finds that cannabis vaping is associated with increased odds of bronchitic symptoms and wheeze, even after adjusting for nicotine vaping, cigarette smoking, and combustible cannabis use.
* The study finds no statistically significant associations between nicotine vaping and respiratory symptoms in fully adjusted models.
* The study suggests that further research is needed to understand the temporality of the association and the mechanisms underlying the difference between nicotine and cannabis in risk of respiratory symptoms.

Main Message:
The main message of this text is that cannabis vaping may be associated with bronchitic symptoms in young adults, beyond the consequences of other drug use behaviors with shared risk pathways. The study's findings highlight the need for further research on the respiratory health implications of vaping, particularly cannabis vaping, in this population. additionally, the study underscores the importance of considering the impact of cigarette smoking and combustible cannabis use when examining the relationship between vaping and respiratory symptoms.
