Routes

Data comes from UNODC, apparently based on law enforcement data on individual arrests between 2011-2016. If they caught the smuggling en route from-to-country they are usually recorded. Sometimes source, target is missing, but if they recorded the production country, code takes that as source, if destination is missing, country of arrest is used.

Report treats the weights of all drugs as equivalent, they are summed per route, to give a general idea of the importance of each route. Code also multiplies tablet based drugs with 100 mg per tablet, to turn them into a kilo weight. Cannabis arrests are removed to focus on harder drugs.

Routes are drawn from country's center coordinate to another's center coordinate, so the places seen at end points of routes are nothing special (not cities, nor ports).

A quick sum on transport method during arrest;
