Cannabis vaping among adults in the United States: Prevalence, trends, and association with high-risk behaviors and adverse respiratory conditions.

Introduction:
This document is a summary of a research study on cannabis vaping among adults in the United States. The study uses data from the Behavioral Risk Factor Surveillance System (BRFSS) to estimate the prevalence and trends of cannabis vaping and its association with high-risk behaviors and adverse respiratory conditions.

Key Points:

* The study found that the prevalence of past-30-day cannabis use and vaping increased significantly between 2017 and 2019, with a more pronounced increase observed among young adults (18-24 years).
* Individuals who vaped cannabis were more likely to be younger, members of sexual minority groups, students, and to report concurrent nicotine vaping.
* Cannabis vaping was associated with heavy alcohol use, binge drinking, and other high-risk behaviors.
* There was no significant association between cannabis vaping and asthma or other respiratory symptoms.
* The study used data from nine states, and data on nicotine vaping was only available for 2017 and 2018.
* The study adjusted for various sociodemographic factors, depression, and combustible cigarette use in the analysis.
* Sensitivity analyses excluding individuals with COPD diagnoses did not alter the inference of the findings.

Main Message:
The study highlights the increasing trend of cannabis vaping among adults in the US, particularly among young adults. The study also found that cannabis vaping is associated with high-risk behaviors, but not with asthma or other respiratory symptoms. however, the study's limitations, such as the use of self-reported data and the cross-sectional design, suggest the need for further research to establish causal relationships. Nonetheless, the study's findings underscore the need for continued surveillance and regulation of cannabis vaping.
