Researchers at Queen Mary University of London have found that the dual use of vapes and traditional cigarettes may actually help smokers quit. This challenges prevailing concerns from health bodies like the US CDC, suggesting dual users are more likely to reduce harmful chemical inhalation and eventually stop smoking.
The study analyzed data from a UK-funded clinical trial involving 886 adult smokers. Participants were provided with either e-cigarettes or traditional nicotine replacement therapy (NRT) as part of a cessation campaign.
While opponents often argue that dual use fails to address the underlying nicotine addiction, the trial data revealed unexpected benefits for those who initially struggled to quit completely.
Smokers who continued to use both products simultaneously were nearly 4.5 times more likely to quit smoking entirely a month later, compared to those who only smoked cigarettes. Furthermore, dual users were 4.5 times more likely to halve their cigarette consumption one year after their quit attempt.
The research also highlighted several key behavioral trends among e-cigarette users:
- Vape users reported experiencing fewer cravings than those using traditional NRT products.
- The majority gradually decreased their nicotine strength over time, with 1 in 10 migrating to nicotine-free vapes after a year.
- Tobacco-flavored e-cigarettes proved unpopular. Users who stuck with these flavors were less likely to remain smoke-free long-term.
Despite these positive indicators for harm reduction and gradual cessation, the researchers emphasized that completely abstaining from all smoking remains the most effective way to protect overall health.
