Research shows that breathing even the smallest amounts of cigarette a day (which amounts to less than one cigarette a day) will increase people risk for dying from a stroke or heart attack by up to 30%. This is alarming. This mean that passive smoker would be at a higher risk and it made me very worry. Smoking kills... Don't be a murderer. You can kill yourself but you don't deserve to take away other people's life.
