Over 51 percent participants in the Liverpool Stop Smoking Service have tried electronic cigarettes and almost 46 percent are currently using them.
The results came from 320 smokers in the Roy Castle FagEnds study, which is designed to understand the number of people who used e-cigarettes and what smokers thought about the products. The data presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool found that smokers are more likely to try e-cigarettes if they are confident that the products are safer than tobacco smoking.
Smokers appear undecided towards e-cigarettes, possibly due to the widely documented uncertainties about safety and effectiveness in helping smokers to successfully break their addiction. Some also viewed using e-cigarettes as an extension of smoking and perceived them as an inferior tool for helping to quit smoking.
Generally e-cigarettes were viewed indifferently. 20 of the smokers were then interviewed by phone and some of these viewed e-cigarettes negatively. Additionally, some participants were misinformed of or misunderstood the risks associated with e-cigarettes.
Frances Sherratt, lead author from the University of Liverpool, said, "Our results show that electronic cigarettes are commonly used by smokers wanting to quit and seek help through the Stop Smoking Services. Many smokers also viewed e-cigarettes negatively or indifferently as a way to stop smoking. This study highlights the need for better education regarding e-cigarettes, to enable smokers to make balanced, informed smoking cessation treatment decisions to help them quit."
Paula Chadwick, chief executive of Roy Castle Lung Cancer Foundation, which helped fund the research, said, "While the research suggests that a high proportion of smokers try e-cigarettes as an aid to quitting, it also shows that many recognise their effectiveness is limited compared to more conventional, proven techniques.
"Lingering issues around their safety and long-term health impact also continue to affect public opinion. People are more likely to be successful with the tailored, one-to-one support of a quit smoking professional and this seems to have been understood by the majority of those surveyed."
Dr Karen Kennedy, Director of the NCRI, said, "This research provides an interesting insight into how many, and why, smokers use e-cigarettes. Tobacco is the single biggest cause of preventable cancer deaths, so understanding how smokers can be better helped in breaking the addiction is extremely valuable in reducing cancer deaths."
