Researchers have found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots, which can increase the risk of heart attack or stroke.
The study, published in the journal Arteriosclerosis, Thrombosis and Vascular Biology, found that tobacco smoke from a hookah caused blood clots to form within an average of about 11 seconds, compared to an average of five minutes for clotting without exposure to hookah smoke.
