Hookah smoke contains a harmful mix of toxins, say researchers.
UCSF research chemist Peyton Jacob III, PhD, and UCSF tobacco researcher Neal Benowitz, MD, both based at San Francisco General Hospital and Trauma Center, said hookah use exposes smokers to higher levels of carbon monoxide, especially hazardous to those with heart or respiratory conditions, and to higher levels of benzene, long associated with leukemia risk.

And compared to non-smokers, Benowitz said, "If you are smoking from a hookah daily, you are likely to be at increased risk for cancer."
Jacob said, "In addition to delivering toxic substances from the charcoal and tobacco, the heat causes chemical reactions in the mixture which produce toxic volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs). Some PAHs are highly carcinogenic and can cause lung cancer."
Intake of nicotine, the addictive component of tobacco, was less with water pipe use.
The findings are published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.
