#Wasted: the intersection of substance use behaviors and social media in adolescents and young adults

• Social media and applications (apps) are popular among adolescents and young adults.
• These digital platforms promote content that is influential regarding substance use.
• There is growing research on social media and substance use.
• Research on mobile apps and substance use is lacking.

Social media and mobile applications (apps) are popular among and frequently used by adolescents and young adults. These digital platforms allow access to content that is influential regarding substance use. Previous research on social media sites such as Facebook and Twitter have described best practices in social media research, documented the prevalence and types of substance use displayed on social media, determined associations between displayed content and offline behaviors, and highlighted potential for interventions. Research on substance use apps has been more limited and can be framed considering both the risk-protectiveness and connectedness of the app.
