There's no way around it; smoking is bad for your health. It harms nearly every organ of the body, even some that you would not expect. Cigarette smoking causes many cancers and other health problems. It is also the cause of nearly one in five deaths in the United States. Some of the many health problems that smoking can cause include: Cancers. Smoking is the most common cause of lung and oral cancers.
