A digital intervention to reduce cannabis use (Ican) was more effective than non-interactive educational cannabis information in reducing grams of cannabis used over 3 months but not more effective at reducing cannabis use days at 6-month follow-up. Cannabis use reductions were maintained in both conditions between 3 and 6 months follow-up.
