More than 200,000 Australians -- smokers and non-smokers -- took part in a research study which ultimately revealed that death from cigarette use is much higher than doctors previously estimated. The journal BMC Medicine reported that smoking just 10 cigarettes daily doubles the chance of death. If you smoke 20 cigarettes daily -- about one pack -- that makes a person four to five times more likely to die from cancer, heart disease or smoke-related illnesses.
I never smoked. I just try a couple of times.
