[Treatment for smoking cessation : situation in 2025].

In Switzerland, smoking has slightly declined in recent years, while the use of new nicotine products such as electronic cigarettes and snus is increasing, especially among young people. All these products cause addiction, with some being potentially less harmful than conventional cigarettes, which remain the most widely used product. Nicotine replacement therapy and bupropion are currently the only approved medications for smoking cessation in Switzerland. Since varenicline was withdrawn, cytisine-an older drug with a similar mechanism of action-has seen renewed interest. Recent studies confirm its effectiveness and acceptability.
