The Lung Buddy Electronic Cigarettes work by atomising liquid which contains water, propylene glycol, flavourants and nicotine, into a fine mist which simulates the look, feel and taste of real cigarette smoke. When pulling on the filter of a Lung Buddy, a sensor activates the microchip which then triggers the lithium ion battery which activates the atomiser. The liquid contained in the filter cartridges is heated to a point of atomisation and a fine mist containing nicotine is released. This mist contains no tar, harmful chemicals and carcinogens.
