BUFFALO, NY — Nearly 80% of smokers who use electronic cigarettes, or e-cigarettes, believe the devices are less harmful than traditional cigarettes, according to a study published in the American Journal of Preventive Medicine and authored by a team of scientists led by Richard O’Connor, PhD, Associate Professor of Oncology and Director of the Tobacco Research Laboratory at Roswell Park Cancer Institute (RPCI).
“This study offers a snapshot in time on the use of e-cigarettes from mid-2010 to mid-2011 and examines awareness, use and product-associated beliefs among current and former cigarette smokers in the United States, Canada, Australia and the United Kingdom,” said Dr. O’Connor.
Nearly 6,000 adult smokers from the four largest English-speaking countries participated in the International Tobacco Control (ITC) Four Country Survey. Study results include:
- Overall, 46.6% of those surveyed were aware of e-cigarettes (US: 73%, UK: 54%, Canada: 40%, Australia: 20%)
- Younger, non-minority, heavy smokers with higher incomes were more likely to be aware of e-cigarettes.
- Younger, non-daily smokers and those who believe e-cigarettes to be less harmful than traditional cigarettes were four times more likely to try e-cigarettes.
- E-cigarette use was higher among non-daily smokers and those who smoke more than 20 cigarettes a day.
- 79.8% of smokers believe using e-cigarettes is less harmful than smoking traditional cigarettes.
- 85% of current e-cigarette users indicate that they are using the devices as a tool to help them quit smoking, yet only 11% had successfully stopped smoking.
“This study provides valuable insights into the use and attitudes surrounding e-cigarettes among smokers,” adds Dr. O’Connor. “However, questions remain regarding the impact of these devices in nonsmokers, such as what potential exists to induce nicotine addiction in non-smokers and/or maintain addiction in current smokers who might otherwise stop smoking.”
Regarding future steps, the researchers suggest that the net impact of e-cigarettes on public health be examined. If evidence shows that e-cigarettes reduce the number of cigarette smokers and do not attract use among nonsmokers, they note, then the net public health effect is likely to be positive.
