“They are as effective at nicotine delivery as puffing on an unlit cigarette,” said Dr. Thomas Eissenberg, from the Virginia Commonwelth University’s Institute for Drug and Alcohol Studies.

This quote was from a CNN article titled “Study: ‘Electronic cigarettes’ don’t deliver”. This article was apparently released before the actual study was released.

When available, we recommend all e-smokers and those with a vested interested in electronic cigarettes and public health, read The Study of Electronic Cigarettes by Dr. Thomas Eissenberg from the Virginia Commonwealth University.

According to Dr. Eissenberg’s graphs:

The study subjects were not getting much nicotine in their systems, but their cravings for a cigarette were decreased as compared to the “Sham”…..even if it wasn’t significantly.

Please note that they used 16 mg/ml e-liquid in the cartridges and the participants were instructed to take 10 puffs from the chosen e-cigarette with 30 seconds between each puff. Individual usage would likely change the results of not only the nicotine content, but presumably of the craving for a cigarette. As the study itself notes, “Variability in product design may influence vapour content and chronic use and/or more intensive puffing (ie, more puffs, greater puff volume) may influence nicotine delivery.”

Based on this study, there appears to be very little danger from nicotine in electronic cigarette vapor. It also appears that the electronic cigarette may not be a suitable quit smoking device.

Good thing the Instead Electronic Cigarette is a smoking alternative. Read, enjoy, and decide for yourself if you want to keep smoking tobacco cigarettes or try an electronic cigarette.
