The term 'problem drug use' is defined in the methods and notes section of the Statistical bulletin.

Methods of estimation are abbreviated: CR=Capture-recapture; TM =Treatment multiplier; PM = Police multiplier; MI = Multivariate indicator; TP= Truncated Poisson; CM = Combined methods; MM= Mortality multiplier; OT= Other methods.

In the case of France, Germany and Portugal the interval represents the highest and lowest bounds of all existing estimates, and the point estimate a simple average of all data points.

In the case of Finland, the original age range of the study is 15 to 54 years old, in the case of Malta, the age range of the study was 12 to 64 years old, in the case of Poland the original age range of the study was all ages. All rates were ajusted for ages 15 to 64.

Target groups may vary slightly between countries owing to different methods and data sources; therefore comparisons should be made with caution.

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.

* - Central estimate was not available; a midpoint was calculated as a simple average of the Low and High estimate
