Nicotine is a highly addictive chemical compound found naturally in the tobacco plant. It is responsible for the stimulating and addictive effects of tobacco products. Nicotine is commonly consumed through smoking cigarettes, cigars, or using smokeless tobacco products like chewing tobacco or snuff. It can also be found in electronic cigarettes (e-cigarettes) and vaping products. Nicotine acts as a stimulant on the central nervous system, leading to increased heart rate, elevated blood pressure, and a release of various neurochemicals that produce feelings of pleasure and reward. However, it is important to note that nicotine is highly addictive and can have negative health effects, particularly when used in excess or over an extended period.
