"This is the first time that we have detected a potential chemical of concern in biological samples from patients with these lung injuries," it said. The Centers for Disease Control and Prevention, more than 2000 infections; due to the use of e-cigarettes or Vape or a related product; while the death of 39 users in the United States.
Most of the patients said they used electronic cigarette (VIP) products containing "tetrahydro canabinol", a component that gives "mood" in marijuana, before the disease.
However, scientists have not deduced exactly how e-cigarette smoking leads to the disease, knowing that vitamin E acetate has been described as a potential factor.
Recently, the Food and Drug Administration found the chemical in marijuana products used by people who have developed pneumonia-related lung diseases.
A spokeswoman for the Department of Health in New York: It was found the oil (vitamin E acetate) in almost all cannabis samples of patients in New York.
While these findings show oil in products, the new findings "provide direct evidence that vitamin E acetate is the leading suspect of lung disease," the CDC said.
The Center for Disease Control and Prevention, which works alongside the US Food and Drug Administration and local health departments, investigated the mysterious disease, analyzing 29 samples, of which 82% were found to contain tetrahydro-canabinol.
Vitamin E acetate can be added to fumigation products on the black market; The CDC explained that the oil can be taken as a vitamin supplement, or applied to the skin, and does not usually cause damage.
However, "previous research suggests that when inhaled vitamin E acetate; this may interfere with normal lung function."
Reported symptoms of e-cigarette-related disease include: cough, shortness of breath, chest pain, nausea, vomiting, diarrhea, and weight loss.
The Center for Disease Control and Prevention said that while it "believes" the link of vitamin E acetate to cases of lung disease; evidence is not enough to exclude the contribution of other chemicals.
The center recommends that people avoid using electronic cigarette products containing tetrahydro-canabinol until further investigations are completed.
