Due to the mode of Shisha smoking—including frequency of puffing, depth of inhalation, and length of the smoking session—Shisha smokers may absorb higher concentrations of the toxins found in cigarette smoke, thus increasing the hazard to the body.
The charcoal used to heat tobacco in the Shisha pipes increases the health risks. Even after it has passed through water, the smoke produced by a Shisha contains high levels of toxic compounds, including carbon monoxide, heavy metals, and cancer-causing chemicals. Shisha tobacco and smoke contain numerous toxic substances known to cause lung, bladder, and oral cancers. A typical one-hour session of hookah smoking exposes the user to 100 to 200 times the volume of smoke inhaled from a single cigarette.
Irritation from exposure to tobacco juices increases the risk of developing oral cancers. The irritation by tobacco juice products is likely to be greater among Shisha smokersthan among pipe or cigar smokers because Shisha smoking is typically practiced (with or without inhalation) more often and for longer periods of time.
