Tencent technology news, e-cigarettes are popular all over the world, at the same time, a series of lung disease cases have been triggered, among which more than 2500 e-cigarettes related lung disease patients have appeared in the United States. According to the latest news from foreign media, the CDC recently identified the main cause of lung disease and even death cases caused by e-cigarettes.
According to foreign media reports, the health monitoring system established in the United States after the terrorist attacks in September 2001 was used to find out the cause of the lung injury related to electronic cigarettes that killed 54 Americans and sent more than 2500 people to hospitals.
Using the system, researchers at the Centers for Disease Control and Prevention found a sharp rise in lung cases in June.

The CDC is still trying to understand how the substance damages lung tissue. It may interfere with natural liquids in the lungs called surfactants, which help make lung tissue elastic, and the by-product of the substance may be another toxic chemical.
Emergency room doctors in Wisconsin first noticed outbreaks of these lung injuries in June. They alerted state and federal health officials, and quickly began investigating the geographic extent of the disease, looking for possible causes.
Investigators focused on the vapors of e-cigarettes containing cannabis extract, especially those purchased online or on the street.
Further research has focused on vitamin E acetate, which is used in some preparations to dilute much more expensive tetrahydrocannabinol oil.
As part of this survey, it is important to know when the e-cigarette-related lung disease outbreak will occur. U.S. health officials want to know when these e-cigarette-related lung diseases first appeared and whether they missed other cases before the initial report. That's why they turn to surveillance data collected from more than 3200 emergency rooms in most states of the United States.
They found that since January 2017, the number of emergency room visits among e-cigarette users has gradually increased.

After narrowing the search to a person under the age of 35, the researchers found a sharp rise in June 2019
The number of cases climbed from June to a peak in September. Since then, the number of cases has declined, but the CDC still counts about 100 cases a week, and the number of deaths continues to rise.
On December 20 th, the Food and Drug Administration also announced measures to crack down on illegal e-cigarettes. The agency blocked 44 websites that promote e-cigarettes. The agency has developed a
