Study casts doubts on e-cigarettes as quitting aid – rt news

Monday 24 March 2014 22.29 E cigarettes deliver nicotine through a vapour

People who use electronic cigarettes do not report higher rates of quitting than regular cigarette smokers, according to a US study published today.

The findings were based on survey answers from 949 smokers, reported in a research letter to the Journal of the American Medical Association (JAMA) Internal Medicine.

Just over 13% of the people in the study reported quitting smoking within one year.

E cigarette use “did not significantly predict quitting one year later,” said the letter, written by three researchers at the University of California, San Francisco.

Among participants who reported using both e cigarettes and regular cigarettes, e cigarette use was not associated with a change in cigarette consumption, it added.

The fact that there were so few e cigarette users in the study just 88, and nine of whom quit may have made any trends more difficult to spot, said the letter.

“Nonetheless, our data add to current evidence that e cigarettes may not increase rates of smoking cessation,” it said.

“Regulations should prohibit advertising claiming or suggesting that e cigarettes are effective smoking cessation devices until claims are supported by scientific evidence.”

E cigarettes deliver nicotine through a vapour, and are currently not regulated by health authorities in the US.
