Figure HSR-1. Number of opioid maintenance treatment clients as rate per 100 of the estimated number of problem opioid users, 2005–06


The graphic shows the estimated or reported number of opioid maintenance clients as a proportion of the number of problem opioid users, estimated by various methods, in each country with available data.

The symbol indicates a point estimate, a bar indicates an uncertainty interval.

Based on countries' estimates of problem opiate use (POU), estimates or estimates of problem drug use and injecting drug use, where case definitions in the country's estimates correspond to POU.

Malta: data are for 2005. Case definition used is 'daily heroin users'.

Finland and Slovakia: data are for 2005.
Germany: Mid-point based on average mid-points from three POU estimation studies in 2006, range indicates lowest minimum and highest maximum number from the three studies.
