Despite challenges, millions have resolved a prior significant alcohol or drug problem, increasingly using online supports as a part of their recovery efforts (e.g., virtual mutual-help group meetings, traditional social networking sites [SNS]). However, the content surrounding SUD recovery-related discussion on SNS such as Twitter remains largely unexamined.
