Which of the following is a chain smoker likely to develop?
a.) hepatitis
b.) lung cancer
c.) blood cancer

A chain smoker will likely develop lung cancer. Cigarette smoke is inhaled into a person's lungs, thereby contaminating the lungs with the carcinogenic effects of tobacco smoke. There are other cancer causing chemicals contained in a cigarette and a chain smoker would inhale smoke from two to three packs of cigarettes a day. This is a habit that surely causes what is called "black lungs" which leads to lung cancer.
