Trial Design

4Treatment groups
Experimental Treatment
Group I: Experimental E-Liquid Order "D"Experimental Treatment4 Interventions
All participants will be given all e-liquids (i.e. all 16 flavor*water concentration combinations (4 flavors and four water concentrations)) in this within subject cross-over design study. Participants will be randomized in the order in which they receive the flavor conditions (across the 2 visits). For each flavor condition, water will be presented in the same order from hypothesized least irritating to most irritating.
Group II: Experimental E-Liquid Order "C"Experimental Treatment4 Interventions
All participants will be given all e-liquids (i.e. all 16 flavor*water concentration combinations (4 flavors and four water concentrations)) in this within subject cross-over design study. Participants will be randomized in the order in which they receive the flavor conditions (across the 2 visits). For each flavor condition, water will be presented in the same order from hypothesized least irritating to most irritating.
Group III: Experimental E-Liquid Order "B"Experimental Treatment4 Interventions
All participants will be given all e-liquids (i.e. all 16 flavor*water concentration combinations (4 flavors and four water concentrations)) in this within subject cross-over design study. Participants will be randomized in the order in which they receive the flavor conditions (across the 2 visits). For each flavor condition, water will be presented in the same order from hypothesized least irritating to most irritating.
Group IV: Experimental E-Liquid Order "A"Experimental Treatment4 Interventions
All participants will be given all e-liquids (i.e. all 16 flavor*water concentration combinations (4 flavors and four water concentrations)) in this within subject cross-over design study. Participants will be randomized in the order in which they receive the flavor conditions (across the 2 visits).
