The fierce debate over whether e-cigarettes can help people quit smoking has taken another twist with a research paper on their use by cancer patients criticised as flawed, reports [s]Reuters Health[/s]. The study of cancer patients who smoke found that those using e-cigarettes as well as tobacco cigarettes were more nicotine dependent and equally or less likely to have quit than those who didn’t use e-cigarettes.
The scientists behind the research said their results raised doubts about whether e-cigarettes had any benefit in helping cancer patients to give up smoking. But that conclusion was questioned by other tobacco and addiction researchers, who said the selection of patients for the study had given it an inherent bias. Peter Hajek, director of the [b]Tobacco Dependence Research Unit, Queen Mary Hospital, University of London[/b], said that the study’s data did not justify the conclusions.
