Nicotine is a stimulating chemical that speeds up the messages circulating between the brain and body. The main psychoactive substance in tobacco products is nicotine. Products such as cigarettes, cigars, pipe tobacco, chewing tobacco, fresh and dried snuff, and all dried leaves of the tobacco plant contain nicotine. Electronic cigarettes do not contain dried tobacco leaves, but may still contain nicotine.

Nicotine affects everyone differently based on: height, weight and health, whether the person is used to consuming it, the amount ingested, the strength of the tobacco, and how much it is in the product. Regular smokers of tobacco products develop a tolerance to the short-term effects of smoking and may experience the following effects after smoking: mild stimulation, increased heart rate, increased ability to concentrate, relaxation, coughing, dizziness, headache, bad breath, fingertips tingling and numbness, decreased appetite, stomach cramps and vomiting. If large amounts of nicotine are ingested, effects such as clouding of consciousness, confusion, fainting, seizures, rapid breathing and respiratory arrest may also be experienced.
In short, nicotine is a highly addictive chemical compound found in the tobacco plant. Using any tobacco product can lead to nicotine addiction. This is because nicotine can alter the way the brain functions, causing cravings for more. What makes tobacco use so deadly are the thousands of chemicals found in tobacco and tobacco smoke.
Gas chromatography - mass spectrometry (GC-MS) technique applied in advanced laboratories is a powerful test method for the separation and identification of compounds based on intrinsic differences in their chemical properties.
The quantitative unit of measurement for nicotine strength is usually indicated on labels as amount per cartridge (mg), percentage by volume (e.g., 2,4% nicotine), or concentration (mg/ml). There is no consensus on how nicotine strength is reported on product labels. Some products list nicotine strength qualitatively, for example, zero, low, medium, high, or super high. While some e-cigarettes do not contain nicotine, most do, and nicotine content varies.
