Adolescent gambling can lead to harms. Harms may include missing and dropping out of school, family disruptions, and substance use. Advertising can have a powerful impact on children and adolescents’ health behaviours. The purpose of this study was to explore the links between exposure to types of gambling advertising and promotions and adolescent gambling behaviours. The researchers used data from the 2017 Australian Secondary Students’ Alcohol and Drug (ASSAD) survey. A total of 6,377 student responses were used in this study. About 6% of students reported gambling in the past month. Most students (81%) had been exposed to some form of gambling promotion or advertisement in the last month. This was most commonly seen on television (85%), social media (46%), or at sporting events (40%). Exposure to online gambling (e.g., websites, social media) in the last month was linked to gambling in the last month and being classified as at-risk or problem gambling.
