Electronic cigarettes, also known as vaporizer cigarettes and e-cigarettes, are devices that release doses of water vapor that may or may not include nicotine. E-cigarettes are powered by a small battery.
Electrical cigarettes or e-cigarettes are by many regarded as healthy alternative to tobacco smoking, but they do cause damage to the lungs, scientists from the University of Athens, Greece, explained at the European Respiratory Society’s Annual Congress 2012, Vienna, on Sunday. Electronic cigarettes, also called e-cigarettes have also been marketed as effective smoking cessation devices.
People were let smoking e-cigarettes for ten minutes, and then they messured the lung capasity breating in and out fast. This is the same kind of test they do when checking asthma and other lung diseases.
“A spirometry test, as well as some others diagnostic procedures were used to measure their airway resistance. Airway resistance is used in respiratory physiology to measure the resistance of the respiratory tract to airflow coming in during inspiration (inhalation) and going out during expiration (exhalation).”
They found that using an e-cigarette caused an instant increase in airway resistance (that is a decrease in breathing ability) that lasted for 10 minutes in the majority of the participants. Actually meaning increased problems with breathing. Below are some of their findings:
- Non-smokers – even among lifetimes non-smokers, using an e-cigarette for ten minutes raised their airway resistance to 206% from 182% (mean average); the researchers described this as a “significant increase”.
- Current regular smokers – among existing regular smokers, the spirometry tests revealed a significant rise in airway resistance to 220%, from 176% after using one e-cigarette for ten minutes.
- COPD and Asthma patients experienced no significant increase in airway resistance from using one e-cigarette for ten minutes.
The test result for those with asthma and COPD I wonder about? Lungs are lungs and it is rather strange that the smokers got the worst results. Is it that those with COPD and Asthma are protected by their medicines that they did not react as much as the others? I find that likely. Then again for some people with asthma pure water vapor can be helpful, while in ohters it is harmful. If the vapor was not added any additive then maybe that is the answer.
The researchers also found
“The devices were found to cause an immediate rise in airway resistance in the lungs – meaning less oxygen is absorbed by the blood.”
“For all of persons involved in the test the e-cigarette caused an immediate rise in airway resistance, lasting for ten minutes.”
“This research helps us to understand how these products could be potentially harmful.”
“We found an immediate rise in airway resistance in our group of participants, which suggests e-cigarettes can cause immediate harm after smoking the device.”
“Ministers are concerned that some brands of E-cigarettes may contain very high levels of nicotine – the addictive substance in cigarettes has also been linked to cancer.”
Regardless what anyone says fresh air is best for the whole body, that is what we are designed to inhale.
