COPD and Asthma E-cigarettes can lead to lung diseases

Vapers of E-cigarettes have an increased risk for chronic lung diseases such as COPD, Asthma and Bronchitis.

The write U.S. researchers, after they had interviewed thousands of people – including steamer, tobacco smokers, Ex-smokers and Non-smokers over a period of two years.

The probability of developing cancer within that time, it was for steamship to 30 percent higher than for abstinent people, like the scientists in the scientific magazine ‘American Journal of Preventive Medicine report.

In the case of tobacco smokers, the probability was approximately 150 percent higher.

Consumption of Liquid and tobacco is particularly dangerous

In total, data were used in the study of more than 19,000 people who had no lung disease.

Within two years there were a total of approximately 1100 participants information on such a disease, such as the analysis of Dharma Bhatta and Stanton Glantz of the University of California in San Francisco showed.

In the investigation it came to COPD, Asthma and Bronchitis. Bronchitis is a permanent inflammation of the respiratory tract, COPD (chronic obstructive pulmonary disease) is characterized by cough, increased sputum, and shortness of breath.

The impact of E-cigarettes on the risk of cancer, researchers have not examined.

“A complete switch from regular cigarettes to E-cigarettes can reduce the risk for lung diseases. However, hardly anyone makes it,” said Glantz, according to the message.

The majority of smokers who switched during the period of investigation to E-cigarette would continue to smoke tobacco.

The concurrent consumer is according to the researchers, but is particularly dangerous. The risk for lung diseases was 230 percent higher than for abstinent people. E-cigarettes in the USA significantly less restricted than in Germany.

“We knew from laboratory studies that E-cigarettes are not hazardous to health, but now we have the first study that observed over the years in the normal life of smokers,” says Robert Loddenkemper, expert for E-cigarettes at the German society for pneumology and respiratory medicine.

In the case of tobacco cigarettes, it took decades to scientifically proven that Smoking can be fatal.

“And now we see that the combination of ingredients from the E-cigarette, the plug, for example, in the Liquid or in the flavors, the health risk significantly increases,” says Loddenkemper, who was not involved in the study.

The researchers Glantz also point to weaknesses in their study. Such diseases could develop over years before symptoms occurred.

In addition, could not be accurately recorded, and how often consumers of E-cigarette vapor-deposited in fact. For the first time, people were not been studied, which were considered at the beginning of the study as a lung sick.

Harmful ingredients in E-cigarettes

Vapers of E-cigarettes inhale the vapor of a nicotine-containing Liquid that is heated.

According to information from the German cancer research center (Deutsches krebsforschungszentrum, DKFZ) are E-cigarettes compared to tobacco cigarettes, very likely to be significantly less harmful. Because of certain harmful ingredients are not or to a lesser extent, are not included.

Previous analyses suggest that there is also damaging substances present in E-cigarette in to a greater extent, writes the Team in order to Glantz.

Animal experiments have also shown that the ingredients of E-cigarettes could be parts of the immune system to suppress.

Katrin Schaller from the DKFZ recommends that E-cigarettes are only subject to Reservation.

“Smokers should use stop as a first Option, the authorised and proven to be effective tools, particularly behavioural therapy, combined with nicotine replacement products.” If that doesn’t work, could a smoker, try exit with E-cigarettes.

They should require, but in any case completely to E-cigarettes, as each continues to be smoked cigarette is harmful.

“Because of the currently unknown potential long-term health consequences of E-Cigarette Smoking, you should plan in the long run, the E-cigarette Smoking set.”

The study is in no way related to the mysterious cases of acute lung disease in the United States.

There, the health authority CDC to 10, according to the US. December, died, 52 people, according to the use of E-cigarettes, 2409 were treated in the hospital. The cause is a Vitamin E Oil obtained is suspected.
