A novel research has found that e-cigarettes may increase the risk among users for not being able to quit smoking.

The research published in the American Journal of Public Health has found that people who have used e-cigarettes are more likely to continue the habit in comparison to those who have not used the device.

Lead researcher Dr. Wael Al-Delaimy, head of the Global Public Health Department at the University of California's San Diego School of Medicine, said that along with his team members they have tracked the smoking behavior of 1,000 smokers in California.

After monitoring them, they have found that those have used e-cigarettes were 50% more likely to continue smoking than individuals who had never used the device. Dr. Al-Delaimy said that the study is based upon the idea that people use e-cigarette to quit the habit of smoking.

But their second hypothesis was that using e-cigarettes, smokers are taking in increased amount of nicotine dose. The research found that those who use e-cigarettes are at increased risk of not quitting smoking.

"Based on the idea that smokers use e-cigarettes to quit smoking, we hypothesized that smokers who used these products would be more successful in quitting. But the research revealed the contrary", said Al-Delaimy.

Other researchers said the study findings have doubted the ability of vaping effect to aid the cessation of smoking in users at all. The research has also found that daily smokers and women were more likely to have tried e- cigarettes.

Authorities concerned are taking steps to restrict e-cigarettes, but some experts have said that the pace of actions is slow. Guidelines are being written for the devices.
