Adjusted analyses controlled for age group (ages 12–14 or 15–17), sex, and ethnicity. Analyses exclude participants who selected the “don’t know” response option for each nicotine belief and perception item. Wave 4 was collected from December 2016 to January 2018; Wave 4.5 was collected from December 2017 to December 2018.
1 Analyses control for absolute harm perceptions of cigarettes.
2 Analyses control for absolute harm perceptions of e-cigarettes.
3 E-cigarettes in PATH are described with the following preamble: “The next questions are about electronic nicotine products, such as e-cigarettes, vape pens, personal vaporizers and mods, e-cigars, e-pipes, e-hookahs, and hookah pens. These products are battery-powered and produce vapor or aerosol instead of smoke. They contain nicotine liquid, sometimes called “e-liquid” or “e-juice,” although the amount of nicotine can vary and some may not contain any nicotine at all. Some can be bought as one-time, disposable products, while others can be bought as reusable kits that are rechargeable. Some common brands include Vuse, Blu, Logic, MarkTen, NJOY, eGo, and iTaste. such as e-cigarettes, vape pens, personal vaporizers and mods, e-cigars, e-pipes, e-hookahs, and hookah pens.
