U.S. health officials said on Thursday there are now 530 confirmed and probable cases and seven deaths from severe lung-related illnesses tied to e-cigarettes, and there are no signs that the mysterious outbreak is easing. "There's no one compound ingredient constituent including vitamin E acetate that is showing up in all of the samples".
Vaping-related illnesses have been linked to seven deaths - two in California and one each in Kansas, Illinois, Indiana, Minnesota and Oregon.
CDC officials said that many but not all of the reported and confirmed cases involved both THC - the psychoactive chemical in marijuana - and nicotine vaping.
'We are recommending people consider not using e-cigarettes, ' CDC officials said during the Friday briefing call.
Meanwhile, the Food and Drug Administration revealed that its criminal investigations unit started tracking leads early on. Almost three-quarters of the cases have been reported among men.
MI and NY have enacted bans on flavored e-cigarettes to discourage young people from using the devices.
IL has reported an eighth death related to the outbreak, state epidemiologist Jennifer Layden said on a conference call with reporters.
Many of the patients reported using numerous vaping products and substances, including a mix of nicotine and THC. Among the cases for which patients' sex and age are available, 72% are in men, 67% are in people ages 18 to 34, 16% are in people younger than 18 and 17% are in people age 35 and older. Regardless of the investigation, youths, young adults, pregnant women and adults who don't now use tobacco products should not use them, Dr. Anne Schuchat, the principal deputy director of the CDC, said during the briefing. Some people used black market products.
"The e-cigarette and vaping-related lung injuries are serious".
In most, if not, all, of these cases, what begins as shortness of breath and chest pain progresses to coughing, vomiting, fatigue, diarrhea, fever and weightloss.
Health officials urged people not to buy vaping products off the street or modify them. "People are dying. We ask you to take these recommendations seriously", she said.
