Tobacco plant

The tobacco plant (Nicotiana tabacum) is a perennial shrub native to the Americas, cultivated mainly for its leaves, which contain nicotine—a natural alkaloid. These leaves are harvested, processed, and rolled into products like cigarettes, cigars, and smokeless tobacco. Nicotine acts as a stimulant, affecting the nervous system and providing feelings of alertness or relaxation. While cultivated for economic reasons, tobacco use poses health risks due to its addictive properties and carcinogenic compounds created during combustion. The plant's cultivation has significant agricultural and social implications worldwide, contributing to both economies and public health debates.
