Tobacco is a plant native to North America that is processed and used in various products like cigarettes, cigars, and pipe tobacco. There are over 70 types of tobacco. It is farmed in many countries around the world. Nicotine in tobacco is highly addictive, similar to heroin or cocaine. When a person quits smoking tobacco, they may experience withdrawal symptoms like depression, anxiety, headaches, appetite changes, and coughing as the body adjusts to not having nicotine. Smoking tobacco exposes the body to gases that can irritate the eyes, nose, throat and lungs. Long-term tobacco use has been linked to many serious health issues such as cancer, heart disease, and respiratory illnesses.
