Problem Opioid Use in the EU, 1995-2004
"Reports from some countries, supported by other indicator data, suggest that problem opioid use continued to increase during the latter half of the 1990s (Figure 9) but appears to have stabilised or declined somewhat in more recent years. Repeated estimates on problem opioid use for the period between 2000 and 2004 are available from seven countries (the Czech Republic, Germany, Greece, Spain, Ireland, Italy, Austria): four countries (the Czech Republic, Germany, Greece, Spain) have recorded a decrease in problem opioid use, while one reported an increase (Austria -- although this is difficult to interpret as the data collection system changed during this period). Evidence from people entering treatment for the first time suggests that the incidence of problem opioid use may in general be slowly declining; therefore in the near future a decline in prevalence is to be expected."
