Abstract
Background
This study aimed to discover which young adults vape, the reasons given for vaping, and which reasons for vaping are associated with continued vaping/smoking.
Methods
In a UK cohort of 3,994 young adults, we explored the association of retrospectively-recalled reasons for vaping by 23 years (collected between 2015 and 2016) with vaping/smoking status at 24 years (collected between 2016 and 2017). Using logistic regression, we assessed the association with vaping behaviour among ever vapers who had ever smoked (n=668), and with smoking behaviour among individuals who regularly smoked prior to vaping (n=412).
Results
Vaping to quit smoking was associated with higher likelihood of vaping (odds ratio [OR] = 3.51, 95% confidence interval [95%CI] = 2.29 to 5.38), but lower likelihood of smoking at 24 years (OR = 0.50, 95%CI = 0.32 to 0.78). Vaping to cut down smoking was associated with higher likelihood of vaping (OR = 2.90, 95%CI = 1.87 to 4.50) and smoking at 24 years (OR = 1.62, 95%CI = 1.02 to 2.58). Vaping out of curiosity was associated with lower likelihood of vaping at 24 years (OR = 0.41, 95%CI = 0.26 to 0.63) but higher likelihood of smoking at 24 years (OR = 1.66, 95%CI = 1.04 to 2.65).
Conclusions
Intention to quit appears important for young adults to stop smoking using e-cigarettes. Public health strategies that encourage vaping specifically for smoking cessation may encourage quitting among young adults.
