Multivariable adjusted models included past 30-day frequency of e-cigarette use, past 30-day combustible tobacco use, gender, race/ethnicity, asthma, physical activity, and past 30-day alcohol use; missing values multiply imputed

^2.

Logistic regression; adjusted odds ratio represents the ratio (relative to reference) of odds of reporting dry mouth frequently or always, holding all covariables constant; Ordered logistic models demonstrated evidence of violating the proportional odds assumption

^3.

Negative binomial regression; adjusted ratio represents ratio of Shortened Xerostomia Inventory score in the category of interest relative to reference, holding all covariables constant

Includes edible products, balms, and tinctures

Abbreviation: OR = odds ratio
