Rostron BL, et al. - Particularly among adolescents and young adults, researchers studied the public health burden of poisoning events involving hookah tobacco in the U.S. Events involving hookah tobacco were analyzed reported by age and over time to U.S. poison control centers between 2001 and 2017 as well as by medical outcome, health care level, and clinical effects. There have been reported a total of 276 relevant poisoning events involving hookah. Findings suggested an association of hookah tobacco use with poisoning events consistent with exposure to high levels of carbon monoxide. Dizziness/vertigo, nausea, headache, and vomiting were common clinical effects.
