Wagoner KG, et al. - The aim of this exploratory study was to examine the placement of various electronic nicotine delivery systems (ENDS) types among tobacco retailers. The results of this study revealed that ENDS availability and placement at the point-of-sale varied by retailer type. The findings suggested that most convenience stores placed ENDS in self-service locations, making them easily accessible to youth. Findings highlighted the need for ENDS regulation at the point-of-sale.
