Did you know that smoking first appeared around 300 years ago but only became popular after World War II? Also, did you know that every year 1 million people die because of smoking? The last 50 years showed us that cigarette smoke contains numerous substances that hurt the human body but we still keep smoking! The all talked about nicotine is a very destructive substance. Just 5 mg can kill a dog by paralizing his nerves and around 50-60 mg can do the same to any human being. Besides this substance you must know that others are even more destructive. By burning, the cigarette releases much more dangerous vapors in the air and indirectly in our lungs. There are many far worse substances in a cigarette we must deal with!
