World Health Organization (WHO) Representative to the Philippines Dr. Gundo Weiler said that it is still not clear if electronic cigarettes (e-cigarettes) are an effective smoking cessation aid. “There are also claims that e-cigarettes lead to reduction in smoking. It is not so clear at this point whether indeed along the line people will have less consumption of tobacco because of those products,” said Weiler.

“They might stop, but they may also start using that, and then later switch to tobacco use. There are a lot of factors,” he added.
