I need to find out if there is any research on the health effects of smoking.

There is a large body of evidence showing that smoking cigarettes can be harmful to your health. It increases your risk of developing many serious illnesses, including lung cancer, heart disease, stroke, and chronic obstructive pulmonary disease (COPD). Smoking also has negative effects on your overall quality of life, including reducing your sense of smell and taste, increasing your risk of respiratory infections, and causing tooth decay.
