|Demographics: Gender, Ethnicity, Age, Education, Income, State of Health|
|Other personal moderators: Quitting history, nicotine dependence, levels of stress, including financial stress, depressed mood, use of intoxicants (e.g., alcohol), time perspective, etc.|
|Environmental moderators: Number of smokers/users in the household and in social network|
|Policy-Specific (proximal) measures of policies on heated tobacco products (HTPs) and of WHO Framework Convention on Tobacco Control (FCTC) policies:|
|Psychosocial Mediator (distal) variables: Social norms for both vaporized nicotine products (VNPs) and cigarettes, outcome expectancies for products, reasons for VNP use, self-efficacy and intentions to quit smoking; relative harmfulness, health concerns, functions of smoking, substitutability of functions to VNP.|
|VNP and Tobacco use behaviors: Key outcomes along with some of the distal variables for intermediary analyses. Use of VNPs and other tobacco products: frequency of use, duration, and intensity of use (e.g., cigarettes per day); usual brand/type of product; quit attempts (smoking), duration of abstinence (smoking), product switching.|
