Method: This is a two-armed randomized controlled design, measuring outcomes in terms of changes in problematic alcohol use up to one year after study recruitment. Participants with problematic alcohol use (AUDIT >7 for men and >5 for women) and/or problematic drug use (DUDIT > 1 for both men and women) are randomized into one of two groups: T1, eScreen referral or Control group. Outcomes on alcohol and drug use as well as health-related symptoms are assessed after 3, 6 and 12 months.
