Recent popularity of Hookah as a symbol of style and status is growing with many myths. When Hookah user inhales through the hose, air is pulled through the charcoal and into the bowl holding the tobacco after it bubbles through water. Many people think this process filters toxins from the tobacco! But in reality, Hookah smoke contains multiple chemicals and water does not filter out many of these. So this flavoured smoke passes into the lungs of the smoker and starts affecting healthy living.
Hookah smoke contains toxic chemicals that come from the burning of the charcoal, tobacco and flavourings. These chemicals may include tobacco-specific nitrosamines, polycyclic aromatic hydrocarbons (PAHs; e.g., benzo[a]pyrene and anthracene), volatile aldehydes (e.g. formaldehyde, acetaldehyde, acrolein), benzene, nitric oxide, heavy metals (arsenic, chromium, lead), and carbon monoxide (CO).
Hookah smoking increases the amount of carbon monoxide (CO) in a person's body to eight times their normal level. One-hour session of Hookah exposes the person to a more dangerous situation compared to cigarette, as the Hookah smoker expels into the air 2-10 times the amount of cancer-causing chemicals and other harmful chemicals. The air in hookah bars also contains significant amounts of toxic chemicals including: aromatic hydrocarbons, carbon monoxide, nicotine, and trace metals.
Hookah smoking habit may increase the risk of several cancers, pulmonary diseases, coronary artery disease, periodontal disease, obstetrical & perinatal problems, larynx & voice changes and osteoporosis.
In crux, Hookah is not good in any ways!
