CDC officials advised people to stop using e-cigarettes until scientists gain better understanding of the epidemic of serious vaping-related lung disease that has sickened as many as 450 people and left at least five dead across 33 states.

The latest deaths were reported Friday by health departments in Indiana, California and Minnesota, following deaths in Illinois and Oregon. State officials say a number of cases involve marijuana products, but caution against drawing any conclusions and say there may be multiple causes.

No device, product or substance has been linked to all cases, Dana Meaney-Delman, who heads the CDC’s response to the epidemic, told reporters on a call.

“While this investigation is ongoing people should consider not using e-cigarette products,” she said, adding that people should avoid buying products off the streets or modifying them in any way.

Her statement stopped short of the recommendations of some public health experts, who want CDC to flatly tell consumers to stop vaping until scientists can clarify the cause or causes of the outbreak.

CDC said it had confirmed 215 vaping-related lung disease cases and was investigating another 235 possibly related to vaping.

Minnesota’s first vaping-related death involved a 65-year-old man with a history of lung issues, the state’s health department said. Indiana and Los Angeles County also reportedly had deaths. The first fatality was reported last week in Illinois. Earlier this week in Oregon, officials said a man who bought marijuana vapor from a dispensary had died.

A major case study published Friday found that 84 percent of 41 Illinois and Wisconsin patients reported using THC — the psychoactive ingredient of marijuana. But more than half of them also used nicotine.

A variety of products and devices were employed by the vapers, and distinct lung disorders were reported, according to the report, authored by top health officials in the two states, which appeared in MMWR and the New England Journal of Medicine. Most of the patients had nausea or vomiting as well as breathing problems and a third were sick enough to be intubated.

New York state officials on Thursday said they had found vitamin E in all the confirmed cases in their state. But FDA said no single substance has been identified in the more then 100 samples it tested. Also, since vitamin E is present in most vegetable oils, its presence might not signal a cause of the disease, scientists said.

Mitch Zeller, director of FDA’s Center for Tobacco Products, said the agency is seeing a “mix of results and no one substance or compound, including vitamin E acetate, has been identified in all of the samples tested.” He also cautioned against establishing a link simply because a substance was in each product, saying it was “just one piece of the puzzle.”

Scientists who have been studying vaping’s health risks for years, such as University of North Carolina physiology professor Robert Tarran, say there are many damaging chemicals in vaping products. “Sad to say, I’m not surprised this is starting to come out,” said Tarran, who has seen lung damage in nicotine vapers.

At least six groups of potentially toxic compounds are found in e-cigarette liquids, including nicotine, carbonyls, volatile organic substances like benzenes, trace metals, poisonous flavoring compounds and microorganisms, Harvard public health expert David Christiani said in separate NEJM editorial.

No conclusions can be drawn just yet, Christiani wrote, but “physicians should discourage their patients from vaping.”
