Editor's note...

This article, if anything, would put me off buying an e-cigarette... I want to know I'm getting my nicotine hit!  All I can say is, from personal experience, the first time I bought juice I bought one which was too low in nicotine (and almost gave up using the e-cig) - the second time, I over-compensated and bought one that was so high, it was almost unsmokable.  Once I got the right level to compensate for your smoking habit, I could swap and change between e-cig and normal cigarette.  I guess it's a matter of taste.

Nicotine is an alkaloid, which is found in certain types of plants, tobacco, tomatoes, potatoes, eggplant and green peppers. When it is absorbed in small amounts into your system, the nicotine can cause stimulation, which can be a feeling of relaxation, calmness and/or alertness. There is current literature available, which states that nicotine by itself has not been proven to promote the development of cancer in healthy tissue. Nicotine also has no mutagenic properties, but that nicotine is addictive.

E-cigarettes continue to create a lot of media buzz and chatter among smokers and smoking cessation experts alike. Today, Professor Thomas Eissenberg of Virginia Commonwealth University published an important study demonstrating that E-cigarettes, despite claims on the packaging and advertising, deliver almost no nicotine to the user.

The study is published in the latest edition of the journal, Tobacco Control. Professor Eissenberg had 16 smokers abstain overnight, then come to the lab. on different days and (a) smoke two of their usual cigarettes (b)puff on two unlit cigarettes or (c) “smoke” 2 leading brands of E-cigarette using their “high nicotine” cartridge (16mg), each brand on a separate occasion. On each occasion he measured the blood nicotine levels before, during and up to 45 minutes after using the products.

As expected, the smokers started off with very low nicotine blood levels (around 2 ng/ml) and went up to around 17 and 20 ng/ml after smoking the usual cigarettes. However, when the smokers used 2 E-cigarettes their blood nicotine levels hardly budged, peaking at 3.5 ng/ml (i.e. not significantly different from before they used the E-cigarette or puffing on an unlit cigarette). Similarly, unlike smoking real cigarettes, the E-cigarettes did not affect heart rate and had a relatively small (but observable) effect of reducing craving for a smoke.

What this suggests is that regardless of how much nicotine is supposed to be contained in the E-cigarette cartridge, almost none of it is transferred via the vapor and absorbed in the human body. As I have previously suggested, the E-cigarettes appear to be a good idea, with intuitive appeal, but ultimately have the status of a neat theatre prop which mimics rather well the appearance of smoking.
Given that it delivers almost no nicotine, it follows that the E-cigarette is unlikely to be effective in reducing nicotine withdrawal symptoms and helping addicted smokers to quit in the long run. Although on initial use, the smoker will likely get some conditioned effects (like Pavlov’s dog salivating on hearing the bell), after repeated use it is likely the smoker will learn that that ‘something is missing”, and notice that it doesn’t really help with their withdrawal symptoms and cravings (like Pavlov’s dogs salivate less and less as the bell is rung and no food appears).

I’ve no doubt that some people will continue to feel that they are ‘getting something” from the E-cigarette and that it helps them nonetheless. And of course many would prefer a product that doesn’t give them any nicotine. However, the lack of nicotine delivery casts doubt on this product’s usefulness for smoking cessation, and also poses questions as to the accuracy of the claims of those who market the product.

There are many articles discussing whether e-cigarette is harmful or not on the internet. How much harm on earth does e-cigarette bring?

Electronic cigarette has been questioned since its invention. The electronic cigarette originally invented by Chinese in 2004, is the patent of Chinese people.

After several years’ development, electronic cigarette has been improved greatly in technology.

The improvements are mainly manifested in the following aspects:
The prototype of electronic cigarette is ultrasonic atomization. When searching for the principle of electronic cigarette through the internet. You can find articles related to ultrasonic atomization.
Secondly, the first generation of electronic cigarette is controlled by mechanical switch.

The latest electronic cigarette is controlled by atomization under high temperature(less than 60 c) and airflow sensor switch with the characteristics of fast response, small size and suitable for production., which has been welcomed by many manufactures. However at present, there is not any standard for the performance of electronic cigarette. All manufactures have just made the performance of electronic cigarette according to their own feeling.

Features of electronic cigarette (www.onlyecig.com)
The key performance includes inhalation degree, amount of smoke, lifespan of battery and cartridge.

Inhalation degree means the comparison with real smoking when you have connected the electronic cigarette, such as whether you will feel relax when you smoke. The feeling of inhalation depends on each one’s smoking habit and vital capacity.

Amount of smoke: the smoke of electronic cigarette directly relates to the feeling of smoker.
Obviously, the lifespan of battery and cartridge, mainly means the capacity of battery, which is the using time of rechargeable battery and times. The lifespan of cartridge means the times of inhalation for each cartridge. At present, there are 2 kinds of cartridges, one is disposable, and the other is recycled.
Items mentioned above are key standards. However, there are many other standards in the test before delivery. Now let’s come into whether tobacco solution of electronic cigarette is harmful or not.

The main ingredients are:
1. Propylene glycol
Appearance: colorless hygroscopic glutinous liquid, almost tasteless and odorless.
Indicator: pharmaceutical grade, industrial excellent grad, industrial first grade.

Applications:
1) produce degradable memory fiber PTT used as raw material.
2) For producing pharamaceutical intermediate.
3) Used as cryoprotectants and organic solvent
2. Glycerol, also called glycerin, used as food sweet additive.

Appearance and property: colorless glutinous liquid, odorless, warm sweet and moisture-absorption.

Applications: applied in gas chromatography stationary liquid and organic synthesis and also used as solvent, gasometer and hydtrulic damping agent, softerner, nutrition for ferment of antibiotics, drier, etc.
Substances mentioned above the ingredients of tobacco solution which the content of more than 20%, and the contents of main ingredients of propylene glycol are much higher than that of glycerol. And the contents of glycerol depend on personal preference because it is sweet. Both of them are the main elements to produce smoke. And the size of smoke depends on the concentration of pure water. The contents of other ingredients are below 1.5% and mainly for preparing various flavors: all ingredients are abstracted from plants and synthesized into fragrance.

Certain amount of nicotine can be added according to the customer’s requirements. The concentrations of Nicotine in cartridge are as follows:
Super concentration: 24mg
High concentration: 16mg
Medium concentration: 11mg
Low concentration: 6mg
Zero concentration: 0mg
