Between 2006 and 2016, EMCDDA numbers show a more than doubling in the rate of drug-induced mortality.
According to an EMCCDA report, "a real increase in drug deaths and in drug related deaths has occurred due to an increase in opioid-related deaths". Also, "The increase in drug deaths that remains after controlling for changes in recording practices is still substantial."
They note that "one should be cautious in interpreting the presented trends as measures of the exact increase in percentage or in absolute terms."
According to a 2014 report, "The National Board of Health and Welfare's overall assessment is that the increase in the drug-related deaths reported is mainly explained by the method changes that have been reported in this report." (Translated. For original text see citation.)
They note that, "A real increase in drug-related death in recent years, however, cannot be ruled out." (Translated.)
The EMCDDA report notes that "the previously reported increasing trends have been exaggerated. The main reason for this is that the changes − or improvements − in recording practices in forensic investigations have led to the detection of more deaths with positive findings of drugs. As reported by the National Board of Health and Welfare (NBHW, 2016), changes in coding practices have also contributed to a false rate of increase"
