Battle Creek - You've Got A Problem!

The Michigan Automatic Prescription Service (MAPS) offers up a lot of information on controlled substance usage as reported from the state's pharmacies.  Their website even provides the raw data for the entire year of 2010, broken down by zip code.
After some research, it was possible to track down the populations for those zip code regions, then break the general use down 'per capita.'
The categories chosen for this snapshot of 2010 were 'stimulants' (meaning, all varieties of Ritalin, Adderall, Concerta, and its chemical relatives), 'hydrocodone' (for all drugs similar to Vicodin), 'oxycodone' (for those like Oxycontin), and 'methadone.'
The 49014 area corresponds to an area near Battle Creek known as "Harper Creek."  The 49015 refers to the "Lakeview" region, with 49016 being those who use a PO box as their primary address, 49017 referring to the city's northern side, and 49037 to the general region known as "Urbandale."
I recommend checking out the MAPS program and looking up your particular region and crafting a similar spreadsheet.  Battle Creek may look to be problematic, but I'm almost thinking that other regions may have a bigger problem....
Now, contemplate the causes.....
