Introduction: This study aimed to examine e-cigarette user reasons for use, changes in their nicotine concentrations, and factors associated with changes in their chosen nicotine concentrations.
Methods: Data was from a convenience sample of 788 adult e-cigarette users recruited in Mississippi, examining user demographics, current/history of use, and their perceptions. 396 (34.64%) participants submitted a survey. Forty participants were excluded. The final sample was 356 for analyses.
Results: Participants had a mean e-cigarette time of use of about 24 months, a mean current nicotine concentration level of 7.767 mg/ml, and a mean initial nicotine concentration level of 8.851 mg/ml. About 56% were using their e-cigarettes for a harm reduction reason. Participants had a mean decrease of 1.084 mg/ml of their self-selected nicotine concentration (t=-1.747, p=0.082). Both linear regression models significantly explained the variance in the self-selected nicotine change score.
Conclusions: Participants reported a decrease in selected nicotine concentration. Total time of e-cigarette use was a significant predictor within the two linear regression models on the self-selected nicotine concentration change score, where increases in time of use were associated with greater decreases in the nicotine concentration change score. Vapers utilizing the e-cigarettes for harm reductions reasons had a greater decrease in the nicotine concentration change score than vapers using their e-cigarette for non-harm reduction reasons. Our findings reflect the existing literature and suggests that vapers will decrease their nicotine. Our study highlights the importance for additional research around changes in self-selected nicotine concentrations, and the use of e-cigarettes for harm reduction or smoking cessation purposes.
