Vaping leaves e-cigarette user with rare lung scarring Study

Doctors say the rare disease was likely caused by fumes from the heating coils used in the 49-year-old's device.

According to the authors of the case study, the woman had smoked cigarettes in her teens and twenties, but stopped after that.

DOCTORS treating a patient with a rare lung disease usually caused by exposure to industrial metals said it may be the first case linked to vaping.

It's thought to affect around 2 per cent of metal factory workers.

It's typically diagnosed in people who work with "hard metals" like cobalt or tungsten, in jobs like tool sharpening, diamond polishing or making dental prosthetics.

So what caused the woman's lung condition? Worryingly, it was probably her vape pen.

When researchers tested the patient's vaping device, they found cobalt in the vapor it released, as well as other toxic metals such as nickel, aluminum and lead.

According to the study, published in the European Respiratory Journal, this is the first known case where the disease has been linked to vaping.

Shahab advised anyone who vapes and notices problems with their lungs to consult their doctor to rule out a link to e-cigarettes. The condition is irreversible and can cause lifetime pulmonary problems. Hard metal pneumoconiosis causes the winding up of damaged lung cells and the formation of "giant" cells visible under the microscope.

"It has a distinctive and unusual appearance that is not observed in other diseases", NBC News quoted the case report's co-author Dr. Kirk Jones, a professor of pathology at the University of California, San Francisco.

Hard-metal pneumoconiosis, which can result in permanent scarring, breathing difficulties and chronic coughing, was reported by academics from the University of California in the US. Laborious-metal pneumoconiosis causes broken lung cells to engulf different cells and kind "large" cells that may be seen clearly beneath a microscope. This scarring cannot be cured, although some patients may show a slight improvement if exposure to hard metal dust ceases and if they are treated with steroids. In the dog trainer's case, she stopped smoking and vaping immediately upon diagnosis. She tried various medications and a steroid, which slightly improved the scarring and her other symptoms. But the condition itself persisted.

The organization, which has been a leader in anti-smoking efforts for decades, says misinformation about e-cigarettes is "rampant" and wants the U.S. Food and Drug Administration to clarify the risks for users. But that doesn't mean it should be treated lightly.

Basically, you wouldn't know you had the condition until it was too late.

The same metals were found in the woman's vape pen juice when it was sent to a lab for testing. There's also a growing body of evidence that e-cigarettes contain toxic and potentially cancer-causing metals.

He continued: "The finding that e-cigarettes deliver heavy and hard metals to users is not a new one".

"The higher temperature involved in vaping cannabis oil compared to normal products may increase the risk that metal from the heating element is inhaled".

E-cigs may be presented as a "lesser of two evils" alternative to cigarettes.

"They focus on the smokers and see harm reduction as a pragmatic way of reducing the devastating health effects of the tobacco epidemic".

The American Lung Association said on Wednesday that it is advocating to the FDA to take action to reduce what it calls "false" claims that e-cigarettes are a safe alternative to smoking tobacco.

The woman vaped cannabis oil, which is what numerous hundreds of cases of lung illness in the United States have been linked to.

This is just the beginning, the researchers suggest.
