It's no secret that drug costs vary from country to country, but the price differential can be amazing.

For instance, the average price of a gram of marijuana in the west African country of Guinea is only one cent, according to the United Nation's 2014 World Drug Report.

However, that same bud would cost a whopping $110 in the United Arab Emirates.

On the other hand, a gram of cocaine that sells for $483 in New Zealand will only cost $2 in Panama.
