CDC Flags One Death, Nearly 200 Illnesses Possibly Tied to Vaping Reuters The U.S. Centers for Disease Control andPrevention said Friday that it had identified 193 potential casesof severe lung illness tied to vaping in 22 states as of Aug.22, including one adult in Illinois who died after beinghospitalized. The CDC has been investigating a "cluster" of lung illnessesthat it believes may be linked to e-cigarette use, although ithas not yet been able to establish whether they were in factcaused by vaping. E-cigarettes are generally thought to be safer thantraditional cigarettes, which kill up to half of all lifetimeusers, according to the World Health Organization. But thelong-term health effects of vaping are largely unknown. No link to specific product In a briefing with reporters, representatives from healthagencies, including the U.S. Food and Drug Administration, saidthey have not linked the illnesses to any specific product andthat some patients had reporting vaping with cannabis liquids. Mitch Zeller, director of the FDA's Center for TobaccoProducts, said the agency was analyzing product samples fromstates to identify any potentially harmful elements thatmay be triggering theillnesses. He said health agencies were trying to learn which specificvaping products were used and whether they were being used asintended or mixed with other substances. "Those kinds of facts need to be strung together for everysingle one of these cases, so that we can see if any other kindsof patterns have emerged," Zeller said. The number of potential cases has more than doubled overthe past week. On Aug. 17, the CDC said it was investigating 94potential lung illnesses in 14 states. Brian King, deputy director of research translation at theCDC's smoking and health division, said it was possible there might have been earlier cases that health agencies had not identified. Possible health implications "The bottom line is that there's a variety of things ine-cigarette aerosols that could have implications for lunghealth," said King, adding that none of those compounds had been directly linked to the recent hospitalizations. In a statement Thursday, Gregory Conley, president of theAmerican Vaping Association, said he was "confident" theillnesses were being caused by devices containing cannabis orother synthetic drugs, not nicotine. Patients have reported difficulty breathing, shortness ofbreath and sometimes chest pain before being hospitalized. Somehave shown symptoms like vomiting, diarrhea and fatigue. "The severity of illness people are experiencing is alarmingand we must get the word out that using e-cigarettes and vapingcan be dangerous," Illinois Department of Public Health DirectorDr. NgoziEzikesaid in a statement earlier. .
