Smoking remains the leading preventable cause of morbidity and mortality worldwide, disproportionately impacting individuals from lower socioeconomic backgrounds. In Belgium, 19% of the population smoked in 2018, with 15% being daily smokers. Although youth tobacco use has decreased, new products like flavored disposable vapes, snus, and electronic cigarettes are becoming more popular, especially through social media. In 2023, 38% of Belgian youth aged 15-20 experimented with vapes, and 16% became regular users, with initiation increasingly occurring through electronic rather than traditional cigarettes. The NPO FARES’ Tobacco Prevention Service, established in 1986, uses a non-stigmatizing, preventive approach to reduce tobacco initiation, minimize risks, and enhance cessation rates. It targets professionals in education, healthcare, and social sectors, providing tailored, long-term interventions such as project support, experiential workshops, and certified training in tobacco control. The service continuously evolves, incorporating innovative methods like gender-sensitive, participatory, and peer-to-peer approaches and fostering life skills to promote health and mitigate risky behaviors among youth. Since 2022, under regional tobacco prevention plans, the service has been developing projects targeting youth aged 11 to 24 years in French-speaking Belgium. The service has supported 54 prevention projects, conducted 35 activities with youth, and trained 576 professionals. Despite a decline in smoking rates among young people, the rise of alternative nicotine consumption methods highlights the ongoing need for this project. The participatory approach, which involves youth directly in prevention efforts, has been effective. However, there is a call for more targeted content and youth-friendly communication, particularly through peer education strategies.
