A new study from Dr. Konstantinos Farsalinos looking at existing evidence on the metal emissions from e-cigarettes has determined that vapers don’t need to be concerned about metal exposure. Vapers’ exposure to chromium, cadmium, copper, nickel, lead and cadmium was found to be between 2.6 and 37.4 times lower than the maximum allowable levels in inhalable medicines.

A new study looking at one-year quit-rates for smokers purchasing their first e-cigarette has found that around 41 percent quit smoking entirely and another 25 percent reduced their cigarette consumption by at least half. The finding contradicts claims that there is no evidence e-cigarettes help you quit smoking, and joins other research in suggesting that quit-rates with e-cigs dwarf those obtained with over-the-counter NRT.

Are second generation e-cigs more effective for quitting than cig-a-likes? The latest clinical trial answers with an emphatic "yes": finding that second-gen e-cigs significantly reduce cravings and many smokers – even ones with no intention of quitting – successfully kick their combusted tobacco habit.

The cancer risk associated with formaldehyde consumption from long-term high-voltage vaping is 5 to 15 times greater than the formaldehyde-related risk from long-term pack-a-day smoking, according to a new study published in the New England Journal of Medicine. However, when you look more closely, the finding isn't quite what it seems.

A new study published in the International Journal of Environmental Research and Public Health has provided more evidence in support of something vapers have known for a long time: that the variety of flavors available is integral to quitting smoking using electronic cigarettes.

A new piece of research looking at Korean adolescents has led to loud proclamations that e-cigs are a gateway to smoking addiction. The finding echoes concerns of late from hysterical anti-smoking campaigners and groups such as the CDC that e-cigs are some type of Trojan horse through which smoking is going to re-capture society.

A new study has investigated the flavoring chemicals in e-liquids, and has generated some concern in the media about their risks, with Time using the headline “E-cigarette flavors may be dangerous, study says.” But is this another example of overstating a minor risk for the purpose of spreading mistrust of e-cigs, or is there actually something to it?

While in the UK, the Royal College of Physicians and Public Health England wholeheartedly endorse vaping and actively refute many of the absurd claims made in opposition of e-cigs, the CDC’s prohibitionist, alarmist mindset continues unabated.

After the release of a new study looking at formaldehyde in e-cig vapor, the media has gone into a predictable frenzy of fearmongering. But what does the evidence really say?

A new piece of research has investigated the concentrations of nicotine, carbon monoxide and various volatile organic compounds after e-cigarette use, and compared them to those from a traditional cigarette.

New research published in the FASEB Journal has found that smoking cigarettes disrupts the body’s internal clock in both the brain and lungs, leading to a decrease in overall activity and disturbance of the sleep cycle in the mice studied.

A new study from UCL researchers takes a look at the facts behind the youth vaping "epidemic" declared in 2018. Looking at the data from the National Youth Tobacco Survey (NYTS) calls many anti-vaping claims into question.

A new study from Dr. Konstantinos Farsalinos has offered confirmation that previous formaldehyde scares were due to “dry puffs,” and that with more capable atomizers (even at high powers), the levels generated are vastly lower than from cigarettes. The study shows that vapers can easily identify dry puffs, and it's only in these conditions that cigarette-like levels of aldehydes are created.

Two recent studies from the US and UK continue to track the problem of the public misunderstanding of the relative risks of vaping and smoking. Science says vaping is much safer than smoking, but people - especially in the US - don't know it. So what's the problem?

The new Cochrane Review of the effectiveness of e-cigarettes for quitting confirms that the evidence to date supports the idea that even poorly performing cig-a-likes are effective for helping smokers either quit entirely or markedly reduce the amount they smoke.

The New England Journal of Medicine formaldehyde study made a lot of people scared about formaldehyde in e-cig vapor. The research was heavily criticized, but the authors brushed off issues as "speculation." They can't do that anymore. Now yet another peer-reviewed study has clearly demonstrated that the original study's method was massively flawed.

The issue of reliability in e-cigarette research is being brought into the limelight recently. So, in the manner of “A Rough Guide to Spotting Bad Science,” is there anything we should be on the lookout for when considering the findings of e-cigarette-related studies? Whether by incompetence or by design, there are many common problems with vaping related research - and how its often reported - that any critical reader of the science should keep an eye out for.

A new study looking into the effect of e-cigarette vapor and liquid on the lungs has found evidence of oxidative stress, inflammation and toxicity, and suggests that dripping is likely worse for you than using a clearomizer or tank. The good news is that while e-cigarettes may be worse than air, the study does indicate that e-cigarettes are much safer than cigarettes.

It shouldn't come as a surprise that a recent study found that teenagers are using e-cigarettes to vape pot. The headline finding is that almost one in five teens who’d tried vaping e-liquid had also tried vaping marijuana, but – as always – such an opportunity couldn’t be allowed to pass by without attempting to blame e-cigarettes for what happened. So, are e-cigarettes a gateway to marijuana now?

A new survey of Minnesota-based middle and high school students has provided further evidence that the potential gateway to smoking is not a genuine concern, but, as is the pattern with such studies, it’s being presented as showing the exact opposite.
