E-cigarettes can help kick the butt

SYDNEY - Nicotine delivered via an e-cigarette can help curb the urge to smoke, says new research.

E-cigarettes are electronic nicotine delivery devices that resemble cigarettes but do not use tobacco. They release a small dose of nicotine with each puff.

“The e-cigarettes that we tested appeared to be as effective as a standard nicotine replacement therapy inhalator in reducing the desire,” says Chris Bullen, associate professor at the University of Auckland, who led the study.

“Our results indicate that e-cigarettes have potential as a method to help people stop smoking, in the same ways as a nicotine inhalator. However, our findings should be seen as preliminary and need to be confirmed for this and other e-cigarette brands.”

“E-cigarettes are popular in the United States and Asia where people report buying them to reduce the cost of smoking, cut down on cigarette consumption, use in smokefree places, relieve tobacco withdrawal symptoms, or help quit smoking,” says Bullen.

But this is the first reputable clinical study to actually examine their effect on smokers,” says Bullen.

The study compared 40 adult smokers who on different days used a Ruyan V8 e-cigarette delivering either nicotine or placebo; a Nicorette nicotine inhalator; or their usual cigarette, says an Auckland release.

“We found that the device delivered nicotine to the bloodstream in a similar way as an inhalator, reduced the desire to smoke, and was acceptable to most users,” says Bullen.

“However further studies are required to examine the potential and safety of long-term e-cigarette use, and a large clinical trial would be needed to determine their effectiveness in helping people stop smoking.”

The research was published in Tobacco Control.
