Though little is still known about the long-lasting effects of electronic cigarettes, they are often peddled as less harmful versions of cigarettes or as an effective form of helping smokers to quit. 

This is because e-cigarettes simulate the feeling of smoking but don't actually burn tobacco.

Instead, smokers consume aerosol vapours. 

But, according to a study published by Environmental Health Perspectives today, it turns out that e-cigarettes may actually pose their own health risks. 

The study draws attention to a certain chemical that is identified in over three quarters of e-cigarettes currently on the market. 

This chemical is called Diacetyl and is linked to a number of serious respiratory conditions including lung cancer. 

Not only this, but apparently e-cigarettes contain other harmful ingredients such as formaldehyde. 

This is definitely not good news for the industry.
