Although some people think cigar smoking is less harmful to their health than smoking cigarettes, cigars and cigarillos are simply rolls of tobacco wrapped in tobacco leaf paper. They come in different sizes but usually contain several times as much tobacco as cigarettes do.
Smoking cigars increases your risk of cancer of the mouth, throat, larynx, lung, esophagus and pancreas. And the second-hand smoke from cigars increases health risks to non-smokers too.
Popular in Indian and other Southeast Asian cultures, bidis are small cigarette-like products that are usually flavoured. The flavouring doesn't make them any less harmful. Studies have linked bidi smoking with an increased risk of developing oral and esophageal cancer.
Kreteks are clove-flavoured cigarettes. Kreteks have not been studied as much as regular cigarettes – but similar to cigarette smoking, kretek smoking has been shown to damage the lungs. The flavouring doesn't make them any less harmful.
