​Vaper’s Tongue: What It Is and How to Fix It.

“Vaper’s tongue” is a condition where — unexpectedly and without warning — the vaper experiences a diminished experience of flavours during vaping, as if the ability to taste were dramatically reduced or diminished. This is a nearly universal phenomenon that arises from time to time for the vast majority of vapers. Duration of the condition may last from one to three days. More than that is rare, but not totally uncommon. Interestingly, less than that is also unusual. After the dreaded vaper’s tongue has struck and afflicted a given vaper.

E-cigarettes safer than smoking says long-term study.

E-cigarettes are far less toxic and safer to use compared to conventional cigarettes, according to research* published in Annals of Internal Medicine today (Monday the 6th of February 2017).

“This study adds to growing evidence that e-cigarettes are a much safer alternative to tobacco, and suggests the long term effects of these products will be minimal.”

Alison Cox, Cancer Research UK

Cancer Research UK-funded scientists found that people who swapped smoking regular cigarettes for e-cigarettes or nicotine replacement therapy (NRT) for at least six months, had much lower levels of toxic and cancer causing substances in their body than people who continued to use conventional cigarettes.

For the first time, researchers analysed the saliva and urine of long-term e-cigarette and NRT users, as well as smokers, and compared body-level exposure to key chemicals.**

Ex-smokers who switched to e-cigarettes or NRT had significantly lower levels of toxic chemicals and carcinogens*** in their body compared to people who continued to smoke tobacco cigarettes. But, those who used e-cigarettes or NRT while continuing to smoke, did not show the same marked differences, highlighting that a complete switch is needed to reduce exposure to toxins.

Dr Lion Shahab, senior lecturer in the department of epidemiology and public health at UCL, and lead author of the publication, said: “Our study adds to existing evidence showing that e-cigarettes and NRT are far safer than smoking, and suggests that there is a very low risk associated with their long-term use.

“We’ve shown that the levels of toxic chemicals in the body from e-cigarettes are considerably lower than suggested in previous studies using simulated experiments. This means some doubts about the safety of e-cigarettes may be wrong.

“Our results also suggest that while e-cigarettes are not only safer, the amount of nicotine they provide is not noticeably different to conventional cigarettes. This can help people to stop smoking altogether by dealing with their cravings in a safer way.”

Alison Cox, Cancer Research UK’s director of cancer prevention, said: “Around a third of tobacco-caused deaths are due to cancer, so we want to see many more of the UK’s 10 million smokers break their addiction.”

“This study adds to growing evidence that e-cigarettes are a much safer alternative to tobacco, and suggests the long term effects of these products will be minimal.

“Understanding and communicating the benefits of nicotine replacements, such as e-cigarettes, is an important step towards reducing the number of tobacco-related deaths here in the UK.”

Notes to Editor

**Previous research into the toxicity of e-cigarettes has focused on assessing concentrations of potentially harmful chemicals within the products themselves, or the vapor they produce.***Levels of TSNAs (tobacco-specific nitrosamines) and VOCs (volatile organic compounds) metabolites were examined – these compounds have well-established smoking-related toxicological and carcinogenic risks.

Vaping is ‘97% Safer’ than smoking, say health experts.

First long-term study of vaping effects show fewer toxins compared to normal cigarettes.

Vaping has been given an emphatic thumbs up by health experts after the first long-term study of its effects in ex-smokers. After six months, people who switched from real to e-cigarettes had far fewer toxins and cancer-causing substances in their bodies than continual smokers, scientists found.

Nicotine patches also appeared to be far safer than tobacco products, according to the analysis of saliva and urine samples. Experts hope the findings will reassure would-be quitters who have been confused by mixed messages about the safety of e-cigarettes.

Some previous studies suggesting that vaping is as harmful as smoking have little in common with real-world experience, it is claimed.

The new findings also show that to be safe it is necessary for smokers to switch over completely to e-cigarettes or nicotine replacement therapy (NRT).

Study participants who failed to make a clean break still had significant amounts of tobacco-related toxins in their saliva and urine.

Lead author Dr Lion Shahab, from University College London, said: “Our study adds to existing evidence showing that e-cigarettes and NRT are far safer than smoking, and suggests that there is a very low risk associated with their long-term use.

“We’ve shown that the levels of toxic chemicals in the body from e-cigarettes are considerably lower than suggested in previous studies using simulated experiments. This means some doubts about the safety of e-cigarettes may be wrong.

VAPING IS SAFE… NO BUTS! Vaping is dubbed ‘very low risk’ and less toxic than tobacco in the first major study into e-cigarettes and vaping.

Experts warned two in three smokers ‘wrongly’ thought e-cigarettes were just as harmful than tobacco.

VAPING has been found to be “very low risk” in a study of its effects on ex-smokers.

The British research says the devices are far less toxic than cigarettes.

A study has found that the effects of vaping has shown to be far less toxic than traditional cigarettes.

Researchers at the University College of London found that levels of cancer-causing toxins fell by up to 97 per cent in those who vape within six months after they switched from cigarettes.

But those who continued to use both saw no benefit.

The study of 181 people found using the devices was as beneficial for health as taking up nicotine replacement therapy.

A chemist’s advice: Don’t Dry-Burn your coil.

Dr Mirosław Dworniczak, a chemist, got interested in vaping since he stopped smoking a few years ago. On the Nicotine Science and Policy Blog, he comments on the Dry-Burn, a common practice that consists in heating a bare coil before using it.

To dry-burn or not to dry-burn?

The Hamlet’s choice of burning dry or not is rather a safety question than of any other concern. As recalled by the chemist, a dry burn consists in applying a lot of power to a bare coil in order to heat it and “clean it up” from manufacturing residuals. It is also used for alignment and spacing.

Such practice, according to the specialists, affects the structure of the alloy or the metal that the coil is made of in surface, and may lead to the production of some particles that will stick to the aerosol and be ingested by the user.

The question of burning dry was previously addressed by Dr Konstantinos Farsalinos who asked for help a material sciences expert, Pedro Carvalho. In their conclusions, the recommended not to burn dry any type of coil.

What is a coil made of?

The chemical composition of heating elements is subject to trends. The heating element is made of a resistance wire that is exposed to an electric current

Different types of resistance wires are used and their grade and quality depend on the brand. As sumarized by Dr Dworniczak, kanthal, stainless steel, nichrome and, lately, pure metals like nickel or titanium are used.

Kanthal is an alloy of iron (Fe, 70%), chromium (Cr, 20-30%), and aluminium (Al, 4-7%). When heated, aluminium oxides form a protective layer on the surface of the wire.

Nichrome is an alloy of Cr (80%) and nickel (Ni, 20%). When heated to so called red hot temperature an outer layer of chromium (III) oxide develops, which protects the heating element from further oxidation.

Stainless steel (SS) has been introduced lately to the vapers market. Steel is an alloy of Fe and carbon (C). The stainless property of steel is due to the presence of at least 13% of Cr. The Cr prevents chromium oxide from forming a protective layer. Some contaminants in the form of trace  metals are present in SS. The classical SS316 contains also small amounts of molybdenum (Mo, 2.5%) and manganese (Mn, 2%).

Why is a dry-burn dangerous?

A dry-burn is dangerous for 3 reasons:

  1. The coating of oxidized material that is formed in surface can peal off during vaping and be transferred to the lungs at the same time as the aerosol, in the form of microscopic particles, or particulate matter.
  2. The particulate matter can cause allergies. Ni, for example, is recognized for causing skin rash, itching, redness.
  3. The particulate matter can also be toxic for the organisms. It is, for example well described in the case of welders exposed to Mn oxides.

For the chemist, a dry burn may amplify the normal corrosion process on the surface of the coil and prematurely deteriorate the quality of the heating element. Toxic (for Mn) or carcinogenic effects (for the Cr(VI), a more oxidized form compared to Cr (III)) are improbable since the dose is very small.

Unintentional dry burn

An unintentional dry burn may also happen when the e-liquid got short in the tank and the cotton is not wet enough. Our advice if it happens, is to get rid of the burnt coil and to mount a brand new one.

Similarly, it is not a good idea to re-use old coils since corrosion has probably developed and already fragilized the surface of the metal. Exchanges of used coils between users is not recommended.

Let’s relativize

There is no reason to think that a dry-burn would make vaping worse than smoking. Nevertheless, it increases the risk of releasing potentially harmful compounds that may be inhaled by the user. In order to check the consistency of a home-made coil and to clean it from manufacturing residuals, a moderate heating of the wire may appear useful, from the experience of vapers.

Those users generally advise building non-touching coils so that they don’t have hot spots. Using a coiler also helps building coils in a reproducible way.

Nowadays, heating elements made of ceramic are present on the market. The testing of such elements is underway and results may be made public shortly. On paper, such material appears to be a safer option compared to alloys or metals.

Since the trend, currently, is towards a safer vape by selecting the best e-liquid quality, by purchasing the most advanced mods that allow a control of temperature, why not following expert’s advice and not intentionally burn the coils?
