Predictors of Vape Shops Going out of Business in Southern California.

Abstract

Vape shops have proliferated in the United States (US) in recent years. As of May 2016, the US Food and Drug Administration (FDA) asserted its authority to regulate electronic nicotine delivery systems. It is critical to understand how these polices have affected the vape shop industry, as the rise and fall of vape shop proliferation has the potential for influencing public health. In this longitudinal study, we examined factors associated with vape shop (N = 77) closure over a 2-1/2-year period in southern California. We assessed predictors of vape shops going out of business using a multivariate logistic regression model. Among 77 vape shops assessed at baseline, 44.2% closed over a 2-1/2-year period. The absence of a "bar type" physical environment (OR = 2.64, 95% CI = 1.12-6.20), poorer shop accessibility (OR = 7.11, 95% CI = 1.17-43.24), fewer reports of qualified personnel (OR = 2.28, 95% CI = 1.12-4.64), less average time spent in shop by customers (OR = 4.8, 95% CI = 1.18-19.60), a narrower e-liquid flavor selection (OR = 6.55, 95% CI = 1.56-27.49), and less vape device diversity (OR = 2.36, 95% C = 1.13-4.91) predicted vape shop closure. The rise and subsequent decline in vape shops could potentially affect public health. However, there needs to be more research on their association with public health..
