Monthly Missouri Resident Heroin Deaths
These charts display the number of heroin- and non-heroin opioid- involved overdose deaths by month. There does not appear to be a pattern of seasonality; instead there is a steady rise over time punctuated by highs and lows. One example of a high is the spike in overdose deaths due to non-heroin opioids in January and February of 2016. The latter part of 2016 continued to increase with the provisional count of March 2017 reaching a new high. DHSS will continue to investigate through more discrete statistical analysis and continued collection of data to determine whether any consistent seasonal trends exist.
