"Concerning the 248 drug-related deaths in 2010 that were recorded by Statistics Norway, 173 (70 %) deaths involved opioids with or without additional drugs (Figure 5), 93 were deaths due to heroin (X42, X44, X62, X64 + T401), 36 deaths were recorded with methadone poisoning as the underlying cause (X42, X44, X62, X64 + T403), and 44 with other opioids, either as poisoning or dependency (X42, X44, X62, X64 + T402, F112). The remaining 75 deaths broke down as follows: 16 other synthetic narcotic substances (X42, X44, X62 + T404), 27 psychostimulants (X41, X44 + T436), 13 unspecified narcotic substances (X42, X44 + T406), 19 cases of dependency on other stimulants and dependency on multiple/ other drugs (F152,F192), and zero deaths from cocaine (T405). In 2010, 25 (10 %) of the included deaths were coded as suicides (X62, X64), which is probably a conservative estimate of the suicide rate."
