Smoking is the major single risk factor for numerous fatal diseases. Smoking damages nearly every organ in the body. It is considered one of the most important risk factors for various types of cancer, heart and circulatory diseases, chronic respiratory diseases, and type 2 diabetes. Furthermore, smoking damages the eyes, the periodontal apparatus, the digestive system, and the genitals, and reduces fertility. Last but not least, it adversely affects pregnancy and damages both the fetus and the newborn baby. Quit smoking—many smokers would like to!

Those who stop smoking—at whatever age—soon begin to feel physical improvements, prevent illnesses that are caused by smoking and significantly contribute towards successful treatment of tobacco-associated disease. Unfortunately, it is often difficult to stop smoking over the long term. The real challenge is to remain a non-smoker permanently after successfully quitting.
