This study looks at the effect of manipulating water concentration on e-cigarettes that contain aldehyde flavor chemicals on sensory perception. Regular e-cigarette users will be asked to complete 2 lab sessions in which they will sample 4 nicotine containing e-liquids. Each e-liquid will be sampled in four water concentration manipulations. Researchers will examine influence of flavor and water concentrations on sensory experience including appeal/liking and irritation and harshness.
