LOS ANGELES, Aug 13 (Xinhua) – US researchers have found that using hookah water for hookah is more dangerous than other forms of smoking, according to a first-of-its-kind study by UCI researchers at UCI.
Using a bespoke tester, UCI chemists analyzed emissions during a typical general plumbing session and found that a pipe pull could contain as much harmful substance as a whole-cigarette smoke.
The study was published in the latest issue of Aerosol Science and Technology.
"The main hookah smoke – one that is directly inhaled by the user – has many toxic and harmful chemicals, such as nicotine, which can lead to tobacco addiction; irritating carbonyl compounds; and gasoline, a known carcinogen," says lead author Veronique Perot , a research associate on the UCI project in the Department of Chemistry.
"Because of the larger volume inhaled for each puff and the longer duration of the smoking session, hookah often delivers a higher dose of these chemicals to the smoker," Perro said.
The pipeline also produced a huge amount of carbon monoxide, mainly from burning charcoal to heat the tobacco or herbal mixture in its bowl, according to the study.
In addition to testing ordinary tobacco, the group tested herbal mixtures with no nicotine for sale as a healthier alternative and found that there were even higher levels of toxic gases present in the mainstream smoke.
"One of the big myths about hookah use is that the water in the bowl actually filters the toxic chemicals, providing a shield for the smoker," Perro notes.
"The study shows that this is not the case for most gases and that, probably due to its cooling effect, water actually promotes the formation of ultra-fine particles," she said. Enditem
