Figure PDU-1:  Estimates of the prevalence of problem drug use (rate per 1000 population aged 15 to 64), 2000 to 2004 – Part (ii) All estimates combined per country

Notes:

CR=Capture-recapture; TM =Treatment multiplier; PM = Police multiplier; MI = Multivariate indicator; TP= Truncated Poisson; CM = Combined methods. For more details see Table PDU-1 to Table PDU-3.

The symbol indicates a point estimate, a bar indicates an uncertainty interval, which can be either a 95 %-confidence interval or an interval based on sensitivity analysis (see Table PDU-3). Target groups may vary slightly owing to different methods and data sources; therefore comparisons should be made with caution. The Spanish estimate does not include problem cocaine use; a higher estimate is available in Table PDU-2 and Table PDU-3, which takes this group into account but which may not be as reliable.

Where no method shortcut is given (CR, TM, PM, etc.), the line given represents an interval between the lowest lower bound of all existing estimates and the highest upper bound of them. The estimate of Czech Republic refers to the age group 18-64.
