The association between dual use of electronic nicotine products and illicit drugs with adverse cardiovascular and respiratory outcomes in a longitudinal analysis using the Population Assessment of Tobacco and Health (PATH) survey
Abstract
Background: Drug use and electronic nicotine delivery systems (ENDS) are independently associated with increased risk of cardiovascular and respiratory outcomes. Literature on the association between the dual use of these key substances and potential health outcomes is limited. Methods: We examined the association between dual use of ENDs and drugs (including heroin, methamphetamine, cocaine, painkillers, and misused stimulant medications) with adverse cardiovascular and respiratory outcomes in a longitudinal analysis using waves 1–5 from the Population Assessment of Tobacco and Health survey (2014–2018). Multivariable logistic regression with Generalized Estimating Equations was utilized. Results: About 0.9% (n = 368) of respondents at wave 2 used both ENDS and drugs, 5.1% (n = 1,985) exclusively used ENDS, and 5.9% (n = 1,318) used drugs. Compared with people who do not use drugs, both those who used only ENDS (Adjusted Odds Ratio (AOR) 1.11 [95% CI 0.99-1.23], P = 0.07758) and those who used only drugs (AOR 1.36 [95% CI 1.15–1.60], P = 0.00027) were more likely to experience adverse respiratory conditions. Individuals who used drugs and ENDS compared to people who did not use drugs or ENDS had the largest odds of respiratory problems among all drug use category comparisons (AOR 1.52 [95% CI 1.20-1.93], P = 0.00054). Individuals who only used drugs had elevated odds of cardiovascular ailments compared to people who did not use drugs or ENDS (AOR 1.24 [95% CI 1.08–1.42], P = 0.00214) and compared to people who only used ENDS (AOR 1.22 [95% CI 1.04–1.42], P = 0.0117). Conclusions: Inhaling electronic nicotine delivery systems and other substances may negatively affect the users' respiratory health.
