The rise of TikTok as a primary source of information for youth, combined
with its unique short-form video format, creates urgent questions about how
substance use content manifests and spreads on the platform. This paper
provides the first in-depth exploration of substance use-related content on
TikTok, covering all major substance categories as classified by the Drug
Enforcement Agency. Through social network analysis and qualitative coding, we
examined more than 2,333 hashtags across 39,509 videos, identified 16 distinct
hashtag communities and analyzed their interconnections and thematic content.
Our analysis revealed a highly interconnected small-world network where
recovery-focused hashtags like #addiction, #recovery, and #sober serve as
central bridges between communities. Through manual coding of 351
representative videos, we found that Recovery Advocacy content (33.9%) and
Satirical content (28.2%) dominate, while direct substance depiction appears in
only 26% of videos, with active use shown in just 6.5% of them. This suggests
TikTok functions primarily as a recovery support platform rather than a space
promoting substance use. We found strong alignment between hashtag communities
and video content, indicating organic community formation rather than attempts
to evade content moderation. Our findings inform how platforms can balance
content moderation with preserving valuable recovery support communities, while
also providing insights for the design of social media-based recovery
interventions.
