This study conducted a systematic observational analysis of English-language online forums related to addiction recovery in late 2021. Out of 207 identified forums, most were general addiction or alcohol-focused, with many located on popular social media platforms like Reddit, Facebook, and Quora. The study examined user activity across 148 forums, finding a median of 27 days between unique user engagements and less than 10 posts per week on forums with recent activity. The research compares metrics of forum activity and explores characteristics that could enhance engagement and support for addiction recovery.
