Notes:

 (2) Caution should be applied when considering that a survey is said to be 'national' as this refers to its intended geographical coverage, but does not mean it is necessarily representative of the national situation, which would depend on any sampling procedures adopted. Note that the size of the prison population surveyed is not available for most of the studies displayed in this table, and sample sizes reflect different proportions of the population in different countries. 

 (4) Bulgaria: due the fear of sanction it is likely that drug use is under-reported.
