All I have to say is those 16mg cartridges would not do anything for me either. To low a nicotine content for a good study on the effectiveness of the electronic cigarette. What do I know I just use one and it keeps me from smoking tobacco cigarettes as long as I have at least 40mg e-juice. Anything lower and I want a stinky cigarette. Something must be working or at least for me. I am not DR. Taz either, just plain Taz so what I say don't count for much, but it is the truth.
Study: 'Electronic cigarettes' don't deliver
Electronic cigarettes" that vaporize nicotine juice to inhale instead of smoke from burning tobacco do not deliver as promised, according to research at Virginia Commonwealth University.
"They are as effective at nicotine delivery as puffing on an unlit cigarette," said Dr. Thomas Eissenberg, at the school's Institute for Drug and Alcohol Studies.
