Cannabis, Vaping, and Respiratory Symptoms in a Probability Sample of US Youth

Purpose: The purpose of this study was to explore the association between respiratory symptoms among U.S. adolescents who were current (past 30-day) users of cigarettes, e-cigarettes, and/or cannabis, as well as lifetime users of cannabis with electronic nicotine delivery systems (ENDS). Methods: Wave 4 from a national probability sample (N = 14,798) of adolescents (12-17 years) using Population Assessment of Tobacco and Health Study data was used for this study. Retention rate was 88.4%. Results: The odds of indicating wheezing or whistling in the chest were roughly two times higher among those who had used cannabis in ENDS (adjusted odds ratio 1.81, 95% confidence interval 1.47-2.22); neither e-cigarettes nor cigarettes had a significant association with all five respiratory symptoms in the fully adjusted models. Conclusions: This study provides preliminary evidence that adolescents' cannabis use with ENDS may have negative health consequences. Lifetime cannabis use with ENDS was substantially associated with higher odds of respiratory symptoms. (C) 2021 Society for Adolescent Health and Medicine. All rights reserved.

Automated summary

The study suggests that adolescents' cannabis use with ENDS may have negative health consequences, while e-cigarettes and cigarettes did not show significant associations with respiratory symptoms.
