The bad news however is that smokers have more to worry about than just carbonmonooxide. A cigarette wrap consists of dried tobacco leaves and chemicals that help even combustion.

Smoking cigarettes, for example, has been shown to cause bronchitis, emphysema, and lung cancer. Marijuana smoke can also cause respiratory problems, including chronic bronchitis. Smoking crack cocaine can also cause .

Carcinogenic deposits — Tar is highly sticky substance and it tends to gel along the nasal and tracheal passage causing damage to the cilia. Continued accumulation of tar leads to the onset of cancer in the lungs, preceded by problems like chronic bronchitis or emphysema.
