E-cigarettes May Make Stopping Smoking More Difficult

New research published in the American Journal of Public Health has found that smokers who used e-cigarettes were less likely to quit regular tobacco use, than those who hadn’t tried the devices.

A research team led by Dr. Wael Al-Delaimy, chief of the Division of Global Public Health at the University of California, San Diego School of Medicine studied 1,000 California smokers for one year.

Results showed that smokers who said they had used e-cigarettes were half as likely to cut down on smoking and 59% less likely to stop altogether, compared to those who had never used e-cigarettes.

As Dr Al-Delaimy explained the latest findings came as a surprise even to the research team. “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. We need further studies to answer why they cannot quit. One hypothesis is that smokers are receiving an increase in nicotine dose by using e-cigarettes.”

The study contradicts the results of a previous review by the Cochrane Library which found nearly 10% of smokers who used e-cigarettes had been able to quit the habit within a year.
