While understanding the costs of drug-related actions is an important aspect of drug policy, there are no recent data available on the total drug-related public expenditure in the Netherlands or trends in spending. No budget is specified and allocated in the drug policy documents, and there is no recent overall review of executed expenditures.
The most recent estimate of total drug-related public expenditure in the Netherlands is from 2003; at that time, it amounted to 0.5 % of gross domestic product. Recent estimates suggest that the public sector spent EUR 384 million to implement the Opium Act in 2015. This budget was spent on prevention, police investigation, prosecution, sentencing, implementation of sentences, supporting offenders and victims, and judicial services.
