How does electronic cigarette work
The device takes the form of a tiny rod which is slightly longer than a normal cigarette.
The mouthpiece of the device contains a replaceable cartridge filled with liquid. The main
substances contained in the liquid are nicotine and propylene glycol.
When air flows through the device, it is detected by a microprocessor. This microprocessor
then activates an atomizer which injects tiny droplets of the liquid into the flowing air.
This produces a vapor mist which is inhaled by the user. The addition of propylene glycol
to the liquid makes the mist better resemble normal cigarette smoke.
The microprocessor also activates a red LED at the tip to simulate real smoking.
The units use a rechargeable battery as a power source. Energy produced by battery is enough to heat the nicotine inside and produce `smoke` like usual cigarettes do. No harmful tars; only nicotine, in small concentrations of course that you can control so whether you want to continue to smoke or embark on a quit programme - the choice is yours
