研究概览
简要总结
Cannabis is the most widely used psychoactive substance around the world after alcohol and tobacco. Although approximately one in ten users develop serious problems of dependency, only a small number attend outpatient addiction counseling centers. CANreduce is an adherence-focused guidance enhanced web-based self-help program with promising results in German and other languages. It also reaches those users who hesitate to approach such treatment centers and help them to reduce their cannabis use.
This study will test the effectiveness of the Spanish version of the enhanced web-based self-help intervention with psychological support, an enhanced web-based self-help intervention (without psychological support) and a waiting list control in reducing cannabis use in problematic users.

盲法说明
The masking technique will be partially single-blinded-in that participants in either of the two active treatment groups will not know which version they work with. The two versions are neutrally described as two differently optimized variants to prevent participants from having a preference of one over the other possibly resulting in a disappointment when being allocated to the unwished version. However, subjects will know whether they have been assigned to treatment-as-usual (TAU). Any blinding of research and study personnel is not warranted.
