INCB data on opioid consumption in Slovenia between 1994 and 1998 are available for codeine, dihydrocodeine, morphine, pholcodine, pethidine and methadone. These data are, however, disputed by palliateurs working in the country. Over the period 1994-8 codeine consumption fluctuated, but declined overall from 16 kg to 6 kg; dihydrocodeine consumption in 1998 was 10 kg; morphine consumption over the whole period ranged from 5-7 kg per annum; pholcodine ranged between 1-10 kg per annum; pethidine consumption fell during these years from 7 kg to 1 kg; whilst methadone rose from 6 kg to 12 kg. The average daily consumption of defined daily doses of these drugs per million inhabitants between 1994-98 was: codeine (148); dihydrocodeine (27); morphine (178); pholcodine (142); methadone (433); pethidine (13).5
