Smoking is very dangerous for the health and causes many diseases especially heart diseases, lung diseases, cancer, throat cancer and skin cancer. So it is obvious that smoking bring a man to death. Because of these bad effects we should avoid the smoking.
I was a smoker myself for 20 years and then just decided to quit cold turkey one day. Due to smoking, I now have COPD (chronic obstructive pulmonary disease) and emphysema to some extent. Nicotine is so addictive and makes it extremely difficult to quit.
