Nicotiana tabacum is the most commonly used tobacco plant for commercial tobacco products. The leaves of the tobacco plant are the source of all smoking and chewing tobacco products. Tobacco leaves contain around 2-8% nicotine.
Tobacco has been reportedly used for many conditions in traditional and folk medicine. Limited research suggests that tobacco may be used to treat Alzheimer's disease, schizophrenia, or nicotine cravings.
However, it is well-known that smoking tobacco represents a major public health concern. Nicotine is highly addictive and contains several compounds known to cause cancer. Nearly one-third of people who try a cigarette later become addicted to nicotine. An estimated 25-35% of all cancer-related deaths are due to nicotine.
