It is already a proven fact that smokers are about twice as likely to die from cancer and three times as likely from heart attacks as non-smokers. Worldwide, smoking is directly responsible for approximately 90% of deaths from lung cancer. For women who smoke and who test positive for the human papilloma virus HPV-16, they can actually increase their risk of contracting cervical cancer by 27 times. Adult smokers are at a 60% higher risk of dying from heart attacks. Still not convinced to put down that cigarette? In a study by the Center for Disease Control it has also been found that smoking reduces life expectancy by about 13 to 15 years.
