Assisting Smokers to Switch to a JUUL E-Cigarette by Devaluing Combustible Cigarettes

Subjects will be instructed to use the JUUL as often as they like during the 12-week product use period. They will also be instructed to use JUUL immediately before each cigarette to relieve their craving as much as possible before smoking their usual brand. The JUUL will also be the first product that they are instructed to use each morning. Smokers will be told to try to completely substitute JUUL for cigarettes by the end of the first week of use.
