Hookah Smoke Exposure Doubles Dangerous Benzene Uptake

Posted on

According to a study published on November 21, 2014 in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, people who smoke a hookah or inhale secondhand hookah smoke may be breathing in the chemical benzene, a substance that previous research has linked with an increased risk of leukemia.

The researchers found that urine levels of a compound called S-phenylmercapturic acid (SPMA), which forms when benzene is broken down in the body, increased more than fourfold in the hookah smokers who smoked at a hookah lounge, and increased almost twofold in people who smoked hookah at home.
