A latest research in the UK, focused not on lung cancer but the amount of carbon monoxide inhaled, has found that Shisha smoking results in carbon monoxide levels at least four to five times higher than among cigarette smokers, and in the worst cases, several hundred times higher.
Higher carbon monoxide levels can result in unconsciousness and brain damage and, in the worst cases, death.
In short, Shisha smoking can be just as dangerous to health as cigarettes, if not more so.
