Highlights
We examined the effectiveness of peer-delivered recovery support services for people with addictions.
A limited amount of evidence was of strong methodological quality.
The definition and role of a peer varies widely.
Overall, peer support was found to be salutary and is associated with improvements in a range of substance use and recovery outcomes.
We provide extensive recommendations to strengthen future studies on peer-delivered recovery support services.
