Mobile app triples the chance of quitting smoking

The study involved 201 smokers who participated in lung cancer screening as part of Finland's first pilot study on lung cancer CT screening, which began in Oulu in November 2022. Lung cancer CT screening has been shown to reduce both lung cancer and overall mortality in smokers while also providing an opportune moment for smoking cessation interventions.

All participants had a long and heavy smoking history (≥15 cigarettes per day for at least 25 years or ≥10 cigarettes per day for at least 30 years). Participants were randomised into two groups: the study group, which used the mobile application, and the control group, which received written cessation materials in line with the national Current Care Guidelines.
