A new study could help to develop better understanding about how different types of nicotine devices can lead to dependence. The research, published in Nicotine & Tobacco Research, suggests that e-cigarettes are less addictive to former smokers, compared to regular cigarettes.
"We found that e-cigarettes appear to be less addictive than tobacco cigarettes in a large sample of long-term users," said Jonathan Foulds, professor of public health sciences and psychiatry, Penn State College of Medicine.
E-cigarettes, which typically deliver nicotine, propylene glycol, glycerin and flavourings through inhaled vapour, have become more popular in recent years, triggering various studies into their safety. They contain far fewer cancer-causing and other toxic substances than cigarettes, but their long-term effects are unknown.
To investigate this, researchers canvassed the opinion of more than 3,500 current e-cigarette users who used to smoke cigarettes.
Professor Foulds said people with all the characteristics of a more dependent e-cigarette user still registered lower dependency for the new device than for cigarettes.
