SDSU Study Reveals Hookah Chemical Linked To Cancer, Heart Disease
Monday, July 17, 2017
Burning hookah tobacco creates a byproduct that's believed to cause lung cancer and heart disease, according to a San Diego State University study released today.
A metabolite of the chemical compound acrolein, called 3-HPMA, was found in the urine of 105 hookah smokers and 103 non-smokers exposed to secondhand smoke at indoor events where hookah tobacco was smoked exclusively, said researchers in the SDSU Center for Behavioral Epidemiology and Community Health.
In the American Cancer Society-funded study, participants provided urine samples the morning of — and the morning after — attending the event.
"We found that after spending an average of three hours at a hookah party, the levels of 3-HPMA in urine increased by an average of nearly 1.5 times in both those smoking hookah and those simply attending the event without smoking hookah,'' said Nada Kassem, lead author of the study, published in the journal Nicotine and Tobacco Research.
"The acrolein levels were even higher in people who smoked hookah on a daily basis,'' said Kassem, a research scientist in SDSU's Graduate School of Public Health. "They had acrolein levels four times higher than those found in a representative sample of non-tobacco users in the United States.''
Hookah has gained in popularity in recent years. Users inhale smoke that's generated by heating hookah tobacco fermented with molasses and fruits, and combined with burning charcoal. The smoke passes through a partially filled water jar.
Kassem is part of an SDSU team that researches the impacts of secondhand and thirdhand smoke. She has specifically investigated hookah smoke for several years.
Three years ago, she published a study which found that people exposed to hookah smoke registered higher-than-normal levels of benzene, a chemical compound linked to leukemia.
"Our results support regulating hookah tobacco products, including reducing additives that produce acrolein, including sugars that sweeten the smell and taste of the tobacco, and humectants, which are used to maintain the moisture of the tobacco,'' Kassem said. "We also recommend posting health warning signs for indoor smoking in hookah lounges, and encouraging bans of indoor hookah tobacco smoking in private homes.''
Kassem has been awarded a $1.4 million grant from the National Institutes of Health to further research the dangers of hookah smoke and is currently in the process of collecting more data.
