Tobacco
Tobacco is a plant grown for its leaves, which are dried and fermented before being put into tobacco products. Tobacco contains nicotine, an addictive substance that can lead to serious health problems such as cancer, heart disease, and lung disease. Smoking cigarettes is the most common form of using tobacco, but it can also be chewed or sniffed. Other forms of tobacco use include cigars, pipes, hookahs, e-cigarettes, and smokeless tobacco. All forms of tobacco use pose serious health risks to users and those around them.
