How long does each QuickMist last?

Each mouth spray contains at least 150 sprays (150 x 1 mg dose). The time that the dispenser lasts depends on the number of cigarettes the user used to smoke and how much additional craving relief is needed. For example, a smoker of 10 cigarettes a day should use 10 to 20 sprays per day, so one dispenser would last one to two weeks.
