Chopsmooke.com Electronic cigarette looks like a traditional cigarette. They are not lit by fire, so there is no smoldering, smoky burn at the tip like you would see when lighting a traditional cigarette. Chopsmooke.com Electronic Cigarette contains Glycol, Water, Flavoring agent, (With Nicotine). When the user inhales the device, the air flow is detected by a sensor. A microprocessor then activates the Cartomizer, which injects tiny droplets of flavored liquid into the flowing air and vaporizes it. This produces steam which is inhaled by the user. The addition of glycol to the liquid makes the steam resemble like the traditional cigarette smoke. The microprocessor also activates an orange LED at the tip to simulate real smoking experience. Each Cartomizer is approximately equivalent to 40 traditional cigarettes. Whereas Each can be inhaled/puffed up to 500 times.
