The New Zealand Drug Harm Index 2016 estimates the social cost of drug-related harms and intervention costs in 2014/15 as NZ$1.8 billion.
The total cost of illicit drug use has been considered as having three components.
- The cost of personal harm, that is, the harms that descend upon an individual as a consequence of their drug use. This will comprise physical health, psychological wellbeing and personal wealth.
- The cost of community harm, that is, the cost of crime attributable to drug use, injury to others, the various harms to family and friends and a reduced tax base.
- The cost of interventions by agencies that occur as a result of attempts to address the harms associated with illicit drug use and include health, education and law enforcement.
