E-Cigarettes causes less cell damage than tobacco cigs.

It has always been known that cigarette-smoke causes cell injury which oftentimes results in severe problems, from heart disease to cancer, although very little was known about the result e-cig vapor has on cells. Fortunately, a fresh study guided by means of a group of Italian researchers and Doctor. Konstantinos Farsalinos, frm Greece, puts vapers' anxious to rest.

E-cigarettes have been put to use instead of analogs for a while now, and although businesses aren't permitted to market them as safer than tobacco smokes, most individuals who use them do this hoping they actually are much less dangerous. Antismoking zealots, in the flip side, are issuing warnings about the dearth of conclusive information regarding their security. There are really a large number of studies that demonstrate e-cig vapor is not as harmful than tobacco smoke, but none that handle the problem of cytotoxicity (toxicity at cellular-level). This latest study headed by Dr. Farsalinos of the Onassis Cardiac Surgery Center in Greece aimed to evaluate the cytotoxicity of e-cig vapor to that of cigarettes, by employing extracts of both to cultured fibroblast cells.

Altogether, 21 kinds of e-liquid were examined, as well as the vapour was drawn into a flask containing 20ml mobile medium. Additionally they prepared tobacco smoke extract from the cigarette, using the ISO procedure. They employed the extracts undiluted and in 5 distinct dilutions (50%, 25%, 12.5%, 6.25% and 3.125%). Following a 24hour incubation period, both cells impregnated with e-cig vapor infusion and those who have cigarettes were examined for viability and compared with cells cultured in clear cell medium. Viability of less-than 70% was considered cytotoxic.

After being subjected to tobacco smoke from just one cigarette for 24-hours, just 5.7% of the cells survived. In contrast, 20 of the e-cigarette samples were found to be almost non-hazardous, with a survival rate of more than 70%. Only 1 of the samples demonstrated light toxicity (51%) in the greatest concentration. In the majority of the examined samples, cell survival rate was close to 100%, but even the worst performing fluid had 795% greater cell survival relative to tobacco smoking, as well as the end result is indeed more remarkable should you take into account they compared one tobacco cigarette with e-cig vapor equal to 3 cigarettes. This investigation concluded that e-cig vapor is significantly less cytotoxic that tobacco-cigarette smoke, even though it has yet to be validated by clinical studies.

"Understanding the chemical makeup is significant, yet analyzing the consequences after exposure is indeed more critical," Doctor Farsalinos, a supporter of tobacco harm reduction, stated. The outcomes of the study demonstrate that, if present, the number of potentially dangerous substances discharged from e-cigarette use is minimal and definitely not sufficient to create any significant adverse impacts in the cells we analyzed." To the problem of longterm studies, Ph.D. Farsalinos said they "cannot be carried out until 10 15 years have passed. However, studies have considerably advanced in the last couple of years and now available data suggest that e-cigarettes are undoubtedly less dangerous when compared with tobacco cigarettes. This is actually the definition of damage reduction."

It is a quite enormous scientific finding, nevertheless a simple on-line search shows no important information website, medical or otherwise has picked this up. Yet the web is filled with posts filled with allegations and bogus statements concerning the risks of e-cigarettes. And worse still is that's what public-health organizations are employing to make their choices, instead that scientific evidence.
