A lot of smokers have turned to smoking electronic cigarettes believing it’s a healthier alternative to real tobacco cigarettes. There many studies showing either that e-cigarettes are less carcinogenic than real cigarettes, or that in fact e-cigarettes are far more dangerous.
The latest study on e-cigarettes shows that they contain a high concentration of a dangerous substance called formaldehyde, which is believed to cause cancer.
The electronic cigarette is increasingly popular among smokers who want to quit the traditional tobacco cigarette, hoping that this alternative is healthier and in time will help them quit smoking altogether.
Unlike regular cigarettes, the e-cigarette does not release smoke but a water vapor.
However, a recent study conducted by the scientists at the Portland State University shows that some of the vapors found in the e-cigarette contain a high concentration of formaldehyde, a toxic substance also found in industrial disinfectant products. Formaldehyde is also used in some glue products, plywood and other household products.
James Pankow, one of the lead authors of the study, explained that the researchers have discovered a hidden form of formaldehyde in the vapors of e-cigarettes. The chemical was not measured previously and Pankow says it can be released after the smoker inhales it. He says that people who smoke e-cigarettes should not assume that they are 100% safe.
Some studies showed that e-cigarettes did not contain any carcinogen substances. However, some e-cigarettes models can allow the smoker to adjust the level of nicotine inhaled by increasing the temperature.
The latest e-cigarette study involved a special e-cigarette that produced nicotine vapor. The vapors were then captured in a special tube for examination.
The scientists used the e-cigarette on different voltages in order to compare the formaldehyde concentration released.
The study showed that when the e-cigarette was used at 3.3 volts, no formaldehyde was released. When the e-cigarette was used at 5 volts, the researchers found 380 micrograms of formaldehyde.
The FDA has proposed new regulations involving the electronic cigarettes and in other countries, new regulations are pending.
The new study on e-cigarettes was published in the New England Journal of Medicine.
