Explanation
The active ingredient in tobacco is nicotine.
Nicotine is a naturally occurring chemical compound found in the tobacco plant (Nicotiana tabacum) and is responsible for the addictive properties of tobacco products. When tobacco is smoked, nicotine is absorbed into the bloodstream, leading to various physiological and psychological effects. Nicotine acts as a stimulant and can produce feelings of relaxation, pleasure, and increased alertness.
However, it is important to note that tobacco use is associated with numerous health risks and is a major cause of preventable diseases such as cancer, heart disease, and respiratory problems.
