The Economist notes:
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.
