A randomised controlled trial was developed and implemented together with police officers working to combat drugcrime at an open drug scene in Stockholm. The aim was to evaluate a method called motivational talks, which areheld by police officers to encourage drug crime suspects to seek help. Relapse into drug crime was compared betweenthe control group and the experimental group to determine whether the treatment, i.e., the motivational talk, had aneffect. The study shows that motivational talks had a small but non-significant impact on relapse into drug crime afternine months, but the effect had disappeared at the second follow-up. Motivational talks might still have other effectson the individual or the police. Studying the use of repeated treatment might be a way of furthering the research onthe effect of motivational talks.
