Measuring the harm from illegal drugs : a summary of the Drug Harm Index 2006 - Research Report 13
The Drug Harm Index (DHI) was developed as the overarching measure for the PSA target to reduce the harm caused by illegal drugs. It combines robust national indicators of the harms generated by illegal drugs into a single-figure time-series index. The harms include drug-related crime, community perceptions of drug problems, drug nuisance, and the various health consequences that arise from drug abuse.
