Figure HSR-1. Opioid substitution treatment clients as a percentage of the estimated number of problem opioid users, 2008 or most recent year available

Notes:

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

The horizontal symbol indicates a point estimate, and the vertical bar indicates an uncertainty interval. The uncertainty interval is obtained by dividing the number of opioid substitution clients by the lower and upper estimates of problem opioid users.

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.

See the data on number of clients in substitution treatment in Table HSR-3 part (i).

The problem opioid use estimates can be found in Table PDU-1 part (iii) and Figure PDU-1.
