With those price differences, it's no wonder the illegal drugs trade is so tough to shut down.. you can lose 9/10 shipments and still be profitable.
Given some more data points, and the above map - one could get some idea of the amount of money involved.
From having a friend who has an addiction to cocaine here in Perth, I can confirm the $285 figure is pretty close to correct, although it is in Australian dollars, not USD, so with that in mind I decided to run some of the figures in the article through a currency converter (against the US dollar) to get a more normalised view.
USD - $97/g USD
CAD - $83.47/g USD
AUD - $227.18/g USD
NZD - $198.87/g USD
The chart says "$ per gram" so I had assumed the prices were already represented in US dollars.
Anyone else got info on local prices? Esp Canada, NZ.
Some of these differences likely reflect the reporting methods, and not the underlying markets.
I decided to use the Big Mac Index to satisfy your hunger for knowledge (pardon the pun) to figure out purchasing power.
Appropriate Links at the end of the comment. As with my above comment regarding street prices here in AU - it is assumed that the prices are in the local currency, so these figures represent local currencies.
US - 27.17 big macs
Canada - 23.71 big macs
New Zealand - 63.67 big macs
Australia - 82.61 big macs
You don't get 'high' from drinking Maté de coca, it actually has less of an effect than coffee.
There are a lot of chemicals and processing that go into making cocaine - it's not just coca leaves.
