Abstract: The present invention relates to a system and method of monitoring and controlling the usage of an electronic cigarette which helps the user gain control over their habit by making them aware of their habit, setting tangible goals, creating personalized plans and ensuring adherence. The usage behavior is communicated to the user by displaying on the body of the electronic cigarette; information such as percentage of current conventional tobacco based cigarette being smoked, total number of conventional tobacco based cigarettes smoked in a day etc. This usage behavior is calculated by correlating the amount of vapor inhaled in one sitting from electronic cigarette to be equivalent to the smoke inhaled from usage of one conventional tobacco based cigarette.
