The lifespan of a Greensmoke cartridge can vary depending on several factors, including individual usage habits and the specific device being used. Typically, a single Greensmoke cartridge is designed to provide the equivalent of about one to two packs of traditional cigarettes. Many users report that a cartridge lasts anywhere from a few days to over a week, depending on how often they vape and their personal preferences for inhalation. It is important to keep in mind that usage intensity can greatly affect cartridge longevity.
