Several companies are currently selling an electronic version of a cigarette.
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 an orange led to simulate real smoking. It not only simulates cigarette smoke but also the temperature of common cigarette's smoke (50-60 °C).
The units use a rechargeable battery as a power source.
The technology is patented by European Patent EP 1 618 803 A1.
Nicotine solution cartridges
The patent mentions four different recipes for the nicotine solution of the cartridge to be used with the electronic cigarette:
Substance | Recipe 1 | Recipe 2 | Recipe 3 | Recipe 4 |
---|---|---|---|---|
Propylene glycol | 85% | 80% | 90% | 80% |
Nicotine | 6% | 4% | 2% | 0.1% |
Glycerol | 2% | 5% | - | 5% |
Tobacco essence | - | 4% | 4.5% | 1% |

Alcohol | - | - | - | 8% |
Health issues
E-cigarettes are marketed as a "healthier" alternative for the consumption of tobacco (in comparison to smoking) since the atomisation of the substance does not produce the particulate matter which results from the combustion of plant material.
A toxicity study of the nicotine solutions has been performed by Prof. Dr. Bernd Mayer.
