Respiratory experts have stated that while it cannot be determined whether electronic cigarettes pose a health risk, they are definitely not effective for smoking cessation. Experts advise consumers not to use electronic cigarettes as a means to quit smoking, and remind smokers that quitting primarily relies on their own determination rather than relying on electronic cigarettes.
In addition, the World Health Organization published a statement in September 2008 specifically addressing electronic cigarettes, stating that there is no scientific evidence to prove that electronic cigarettes are a safe and effective smoking cessation tool. The World Health Organization does not consider electronic cigarettes to be a legitimate nicotine replacement therapy for smokers trying to quit. Countries such as Australia and Denmark have enacted regulations to restrict or prohibit the sale of electronic cigarettes.
