tobacco

Tobacco is a plant whose leaves contain nicotine, a highly addictive chemical. It is commonly used in products like cigarettes, cigars, and smokeless tobacco. When smoked or chewed, tobacco releases chemicals that affect the brain, creating feelings of pleasure and alertness. However, it also introduces harmful substances that can damage the lungs, heart, and other organs, increasing the risk of serious health problems such as cancer, respiratory diseases, and cardiovascular conditions. Despite its addictive nature and health risks, tobacco use remains widespread globally, largely driven by social, cultural, and marketing factors.
