A hookah (Hindustani: (Nastaleeq), (Devanagari), IPA; also see other names), shisha, or waterpipe is a single- or multi-stemmed instrument for heating or vaporizing and then smoking either tobacco, flavored tobacco (often muʽassel), or sometimes cannabis, hashish, and opium. The smoke is passed through a water basin—often glass-based—before inhalation.
The major health risks associated with smoking tobacco, cannabis, opium, and other drugs through a hookah include exposure to toxic chemicals, carcinogens, and heavy metals that are not filtered out by the water, alongside those related to the transmission of infectious diseases and pathogenic bacteria when hookahs are shared. The hookah or waterpipe use is a global public health concern, with high rates of use in the populations of the Middle East and North Africa as well as in young people in the United States, Europe, Central Asia, and South Asia.
The hookah or waterpipe was invented by Abul-Fath Gilani, a Persian physician of Akbar, in the Indian city of Fatehpur Sikri during Mughal India; the hookah spread from the Indian subcontinent to Persia first, where the mechanism was modified to its current shape, and then to the Near East. Alternatively, it could have originated in the Safavid dynasty of Persia, from where it eventually spread to the Indian subcontinent.
Despite tobacco and drug use being considered a taboo when the hookah was first conceived, its use became increasingly popular among nobility and subsequently widely accepted. Gradually, burned tobacco has been commonly replaced by vaporizing flavored shisha. Still the original hookah is often used in rural South Asia, which continues to use Tumbak (a pure and coarse form of unflavored tobacco leaves) and smoked by burning it directly with charcoal. While this method delivers a much higher content of tobacco and nicotine, it also imposes more adverse health effects compared to vaporized shisha hookahs.[citation needed]
The word hookah is a derivative of "huqqa", a Hindustani word, of Arabic origin (derived from ḥuqqa, "casket, bottle, water pipe"). Outside its native region, hookah smoking has gained popularity throughout the world, especially among younger people.
Currently instead of copper, brass, and low quality alloys, manufacturers increasingly use stainless steel and aluminium. compounds are used for hookah hoses instead of leather and wire. New materials make modern hookahs more durable, eliminate odors while smoking and allow washing without risks of corrosion or bacterial decay. New technologies and modern design trends are changing the appearance of hookahs. Despite the obvious benefits of modern hookahs, because of high production cost and lack of modern equipment in traditional hookah manufacturing regions, most hookahs are still produced with older technologies.
