E-cigarettes can damage lungs too

Electronic cigarettes are being marketed as a potentially safer alternative to normal cigarettes, but new research has shown that they are still causing harm to the lungs. The study has also added new evidence to the debate over the safety of alternative nicotine-delivery products. Electronic cigarettes are devices that deliver nicotine through a vapour, rather than smoke. There is no combustion involved but the nicotine in the device is still derived from tobacco. There has been much debate over the safety and efficiency of the products, but little scientific evidence to support either claim. Electronic cigarettes are devices that deliver nicotine through a vapour, rather than smoke.

The study included 8 people who had never smoked and 24 smokers, 11 with normal lung function and 13 people with either chronic obstructive pulmonary disease (COPD) or asthma. Each person used an electronic cigarette for 10 minutes. The researchers then measured their airway resistance using a number of tests, including a spirometry test. The results showed that for all people included in the study, the e-cigarette caused an immediate increase in airway resistance, lasting for 10 minutes. In healthy subjects (never smokers) there was a statistically significant increase in airway resistance from a mean average of 182 percent to 206 percent.

FDA proposes to regulate electronic cigarettes under less-strict tobacco rules

The Food and Drug Administration said Monday it plans to regulate smokeless electronic cigarettes as tobacco products and won’t try to regulate them under stricter rules for drug-delivery devices. The federal agency said in a letter to stakeholders Monday that it intends to propose rule changes to treat e-cigarettes the same traditional cigarettes and other tobacco products. The news is considered a victory for makers and distributors of the devices, which continue to gain popularity worldwide. E-cigarettes are plastic and metal devices that heat a liquid nicotine solution in a disposable cartridge, creating vapor that the “smoker” inhales. A tiny light on the tip even glows like a real cigarette. Users and distributors say e-cigarettes address both the nicotine addiction and the behavioral aspects of smoking — the holding of the cigarette, the puffing, seeing the smoke come out and the hand motion — without the more than 4,000 chemicals found in cigarettes. First marketed overseas in 2002, e-cigarettes didn’t become easily available in the U.S. until late 2006. Now, the industry has grown from the thousands of users in 2006 to several million worldwide, with tens of thousands new e-smokers every week.
