Reviews were identified by searching the Cochrane Library.
Reviews were selected if they included randomised controlled trials of interventions to reduce or prevent tobacco use that had ≥6 months of follow up with outcomes of sustained abstinence or point prevalence quit rates.
Extracted data included interventions and outcomes.
