Leveraging Social Media to Disseminate Evidence-Based Messaging About Substance Use to Reduce Stigma and Promote Harm...

Adolescents and young adults (AYAs) who are at risk for harms related to substance use are often not the focus of harm reduction strategies. There is a need for AYA-responsive digital health communication strategies that reflect how they consume information and make decisions about substance use. While social media can contribute to the perpetuation of stigma and normalization of substance use behaviors, it also holds potential to improve health literacy, reduce stigma, and promote effective harm reduction interventions.

This commentary is based on a structured literature review conducted using PubMed. Search terms included "social media", "TikTok", "Twitter", "Instagram", "substance use disorder", "addiction", "evidence-based medicine", "social stigma", "stigma reduction", "youth", "adolescents", and "young adults". Articles were selected based on their relevance to social media use, substance use behaviors, stigma, public perception, and health communication among AYAs. Additional references were identified through manual review of citations in selected articles.

Prior research has highlighted the promise of social media to disseminate accurate public health-related information, while mitigating the spread of misinformation. Additionally, interventions that leverage social media influencers to spread health-based information have demonstrated efficacy in promoting evidence-based mental health messaging.

Developing a deeper understanding of how AYAs engage with social media-and how it shapes their behaviors, perceptions, and attitudes toward substance use-may provide valuable insight for developing evidence-based messaging regarding substance use to educate youth about risk and treatment. Social media may be leveraged to disseminate credible information about substance use, promote harm reduction strategies, and increase awareness of available treatments.
