According to researchers, when someone smoked shisha or herbal cigarettes, it breathed carbon monoxide levels that can not be measured. In fact, in one session of shisha smoke, carbon monoxide is inhaled amount of 4 to 5 times more than that produced by a cigarette. High levels of carbon monoxide can cause brain damage and loss of consciousness. According to the research team, it is rather difficult to know the amount of carbon monoxide (CO) resulting from inhalation of a cigarette because of the differences of each individual. Even so, the CO content of exhaled breath nonsmokers normally approximately 3 ppm (parts per million of air), in light smokers approximately 10-20 ppm and 30-40 ppm in heavy smokers. Research shows, exploiters shisha have 40-70 ppm of CO in the breath.
The number of disorders that affect the blood circulation of about 8-12 percent. "We found that one session of shisha smoke fruit tobacco use 10 milligrams for 30 minutes, or at least a short session, resulting in levels of carbon monoxide four or five times higher than smoking," said Dr. Hilary Wareing, Director of The Tobacco Control Collaborating Centre. In other words, shisha 400-450 times worse than cigarettes. In addition to high levels of CO is inhaled, Qasim Choudhory, workers from NHS Stop Smoking Service, UK, says that the use of shisha pipes in turn could be a medium of spreading the infection. "There is a risk of contracting tuberculosis, herpes, or other infections," he said
