Background<\/h3>\n\n\n\n

During the last 20 years, the number of treatments due to primary cannabis problems in German settings for addicts has increased ten-fold. For these clients, established therapy programmes with proven evidence of efficacy, tailored for the specific needs and problems of adolescents and adults with cannabis use disorders, were lacking.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Method<\/h3>\n\n\n\n

Within the scope of the randomised-controlled intervention study CANDIS, a cannabis withdrawal programme was developed and tested on n=122 probands at the Institute for Clinical Psychology & Psychotherapy, Technical University Dresden<\/em> (2004 \u2013 2007).<\/p>\n\n\n\n

The brief therapy (10 sessions) is based on the modules of motivation enhancement, cognitive-behavioural therapy and problem-solving training. Besides a fully standardised therapy condition (ST, n=51) a targeted standardised therapy (TST, n=39) was developed and adapted to the specific problem profile of the individual patient (motivation, psychosocial problems and comorbidity). The effectiveness of both therapy conditions was compared with a waiting control group (WKG: 8 weeks; n=32). Stability of treatment was assessed catamnestically three and six months after treatment conclusion.<\/p>\n\n\n\n

Results<\/h3>\n\n\n\n

Participants of the CANDIS Study were mainly of mail gender (79%), approx. 24 years old and came from all population strata. Besides cannabis dependence (89%), additional mental disorders were present such as: affective disorders (37%), anxiety disorders (43%), alcohol abuse\/dependence (39%), abuse\/dependence of other illegal drugs (39%).<\/p>\n\n\n\n

80% of all therapy participants (n=90) gained well from the treatment (50% abstinent, 30% significantly reduced consumption). Retain quote was around 86%. Additionally, significant improvements were assessed concerning frequency of use during the last 7 days, severity of dependence, days of sick leave and psychopathology. Treatment effects remained stable in the catamneses three and six months after therapy conclusion.<\/p>\n\n\n\n

Conclusion<\/h3>\n\n\n\n

The results of the evaluation study suggest that cannabis disorders can be treated effectively with the CANDIS behaviour-therapeutic brief therapy.<\/p>\n\n\n\n
