Yes, The Economist actually researched and then made a graphic about the price of cocaine in different countries. While I personally have no use for this information, perhaps it says something about the magazine’s readers?

THE street price of cocaine varies enormously. The drug costs less in South and Central America, where most cocaine is produced, but it is also low in Morocco, a trafficking destination. Worldwide, prices range from $2 a gram in Panama to over $300 in New Zealand, according to the UN’s World Drug Report. Generally, the farther away a country from the main producers and the more isolated it is, the higher the price charged. The priciest places for a cocaine habit are New Zealand and Australia, where a gram typically costs $312 and $285 respectively. Prices in Canada and America, after years of cheaper drugs for Canadians, are now on a par at around $97 a gram.
