Continued Vaping After Quitting Smoking Linked to Reduced Relapse Risk

Smokers who continue vaping after quitting may face a lower risk of relapse, according to new research.

A randomized controlled trial involving 886 smokers analyzed relapse rates over two periods: 4 weeks to 1 year, and 6 months to 1 year. Participants who continued using e-cigarettes (EC) after quitting showed lower relapse rates compared to those who switched to nicotine replacement therapy (NRT) or stopped vaping entirely.

The study, a secondary analysis of a prior trial, confirmed that e-cigarettes are more effective than NRT for smoking cessation.

Professor Peter Hajek said:

"EC use carries only a small fraction of the risks of smoking. Among people who quit smoking with the help of vapes, on-going vaping prevents relapse. It would have a positive health impact and should not be discouraged."

Hayden McRobbie added:

"A big question in helping people stay smokefree is how best to prevent relapse. For people who have quit smoking using EC, carrying on vaping for as long as they need to feel confident they won't slip back to smoking is likely to be beneficial."

Dr. Francesca Pesola emphasized the need for further studies to confirm long-term effects. The research does not provide clinical guidance but suggests ongoing vaping may reduce relapse risk. No independent expert commentary was included in the source.
