ISLAMABAD: People may think hookah is a safe alternative to cigarettes, but a new study shows hookah users are still exposed to cancer-causing compounds.
Laboratory tests have suggested risks from hookah, also known as water pipes.
But the new study published in Cancer Epidemiology, Biomarkers & Prevention is the first to link real-life hookah use to exposure to nicotine and other harmful chemicals, researchers said, Fox News reported.
“One of the main reasons for doing this study is water pipe smoking is becoming much more popular – especially among younger people and college students,” said Gideon St.Helen, the study’s lead author from the University of California, San Francisco.
Water pipes consist of a long tube attached to a glass or plastic container that holds water. The tobacco, which is flavored with fruits and sugar syrup, is burned using charcoal.
The smoke passes through the water before being inhaled.
Users often believe that the water filters out the toxins in the smoke, but Thomas Eissenberg said that’s not the case.
“What the water does do is not filter the smoke, but cools the smoke so it’s very easy to inhale,” said Eissenberg, of Virginia Commonwealth University in Richmond, who has studied water pipe smoking.
For the new study, the researchers recruited 55 people from the San Francisco area who almost exclusively smoked hookah. They were asked to abstain from smoking any nicotine products during the week before going to a hookah bar for the study.
The participants provided three urine samples: one before smoking hookah, one immediately after and another the next morning.
After analyzing participants’ urine samples, the researchers found that nicotine levels increased 73-fold following the hookah session.
They also found significant increases in other compounds that have been tied to increased risks of heart and respiratory diseases and to lung and pancreatic cancer.
