Researchers from the University of Oxford analyzed 14 research reviews published between 2014 and 2023.
The aim was to determine which smoking cessation methods are the most effective, according to SciTechDaily.
At the same time, the review, published in the journal Addiction, shows that significant gaps in research still remain.
For example, only a limited number of studies compare e-cigarettes with other smoking cessation aids such as cytisine and varenicline.

The researchers also point out that most existing studies have been conducted in high-income countries. As a result, they are calling for more research from low- and middle-income countries.
Risks still being investigated
The researchers emphasize that uncertainty remains regarding serious side effects linked to e-cigarettes.
Future studies should therefore follow users over longer periods.
According to the researchers, future research should examine both the effectiveness of e-cigarettes and their potential health risks.
