WHO - Marketers of electronic cigarettes should halt
unproved therapy claims
The typical electronic cigarette is made of stainless steel, has a chamber for storing liquid nicotine in various concentrations, is powered by a rechargeable battery and resembles a real cigarette. Users puff on it as they would a real cigarette, but they do not light it, and it produces no smoke. Rather, it produces a fine, heated mist, which is absorbed into the lungs. Developed in China in 2004, the electronic cigarette is sold there and in numerous other countries, including Brazil, Canada, Finland, Israel, Lebanon, the Netherlands, Sweden, Turkey and the United Kingdom.
“The electronic cigarette is not a proven nicotine replacement therapy,” said Dr Ala Alwan, Assistant Director-General of WHO’s Noncommunicable Diseases and Mental Health Cluster. “WHO has no scientific evidence to confirm the product’s safety and efficacy. Its marketers should immediately remove from their web sites and other informational materials any suggestion that WHO considers it to be a safe and effective smoking cessation aid.”
Marketers of the electronic cigarette typically describe it as a means to help smokers break their addictions to tobacco. Some have even gone so far as to imply that WHO views it as a legitimate nicotine replacement therapy like nicotine gum, lozenges and patches. But WHO knows of no evidentiary basis for the marketers’ claim that the electronic cigarette helps people quit smoking. Indeed, as far as WHO is aware, no rigorous, peer-reviewed studies have been conducted showing that the electronic cigarette is a safe and effective nicotine replacement therapy.
