Vulnerable groups such as young people as active online users are at high risk of exposure to gambling advertising on social media. The Gambling Free Feed project aims to support young people, especially at-risk gamblers, affected ones and professionals to build healthier attitudes towards gambling to prevent gambling related harms.<< Implementation >>During the project we are going to develop experts by experience model to prevent gambling related harms, volunteer work model to reduce youth gambling related harms and e-learning training platform to prevent youth gambling harms. We are also implementing volunteer work by campaigning and influencing (youth for responsible gambling culture). The important activity is to ensure youth participation in the field of gambling harms prevention.<< Results >>Youth gambling related attitudes changes through active participation and volunteering. Young people, their closed ones and professionals will get tools to recognize gambling content on social media and develop a critical approach to it. The outputs of the project will be a handbook for implementing gambling harms prevention in youth volunteer work and an e-learning training course to prevent and reduce youth gambling related harms.
