Your chances for having a heart attack are twice those of non-smokers. Smoking is linked with emphysema, chronic bronchitis and other respiratory ailments. Smoking greatly increases your risk of mouth and throat cancer. Cigars have more nicotine, and one cigar has as much tobacco as 15 cigarettes. Even if you don't inhale cigar smoke, you run a big risk of mouth or throat cancer.
Tobacco is dangerous in all forms.
And there is nothing endearing about its other side effects, like bad breath, stained teeth and smelly clothing. It's also expensive. It's you vs. tobacco, and the race is about to begin. First you need to be positive about your intent to compete. Be sure you want to quit.
