The internal workings of a electronic cigarette are very simple really. The most interesting part is the microchip, or the brain of the e-cigarette. It’s tiny, yet it operates the e-cigarette with the help of a air flow sensor, and it even has a Light Emitting Diode (LED) to indicate when it’s on, when the battery is low and when it’s recharging or fully charged.

The cartridge is also pretty simple yet ingenious: a metallic spiral slightly heats up to evaporate a flavored mix of propylene glycol, glycerin and nicotine, which is held in the sponge-like fiber material. Some electronic cigarettes may look different depending on the manufacturer but the designs are very similar.

After many previous failed attempts at quitting smoking I stumbled upon electronic cigarettes and decided to give them a try. It has been five years now that I smoked my last tobacco cigarette and I am 100% nicotine-free!
