Social cost-benefit analysis of Cognitive Behavioral Therapy for alcohol and cannabis addiction

Abstract

Abstract Background A considerable number of people with an alcohol or cannabis addiction currently do not receive addiction care. Some hundreds of thousands persons in the Netherlands suffer from alcohol dependency, while some tens of thousands adolescents suffer from cannabis addiction. Methods A (hypothetically) enhanced uptake of CBT in specialized addiction care centers was modeled using the SCBA approach. Two SCBA’s were performed: one with respect to alcohol addiction and the other regarding cannabis addiction among adolescents. Results Per person treated with CGT, these benefits accumulate to about 12,000 euro (range 10.000 - 14.000 euro). These profits originate from improved health and less mortality, improved quality of life and higher productivity. A decrease in the number of persons with an alcohol addiction will also lead to lower costs for police and justice following from less criminal activities. Furthermore, CGT is effective as treatment for adolescents with cannabis addiction. Per person treated with CGT, societal benefits accumulate to about 11.000 euro (range 9.700 - 13.000 euro). Here, the net benefits arise from improved health, improved quality of life, reduced early school leaving and higher incomes for those clients who have successfully participated in CGT in addiction care. Conclusions This study shows that society can benefit from an increase in people treated with CGT in specialized addiction care. Such an increase in number of people treated could for instance be realized by educational programs for professionals who come across people with dependency problems, such as general practitioners, professionals working in emergency care and youth care.
