Some more information about cocaine..

Also cocaine depends a lot from a exchange rates..: in 2007 year exchange ratr of a dollar fell down, and at the same time euro rised up,so it began unprofitable to drug-sellers to purvey cocaine to US,so they started to sell drugs to europe,what is much more better for them...I took that information from http://economics.about.com , and quoting that text: "It’s far from clear what caused the brief price hike in 2007... The more plausible explanation is that cocaine producers were targeting more lucrative markets. The rise of the euro and the concomitant decline of the dollar have made it less profitable to sell cocaine to Americans. Officials at the Spain conference said a kilogram of coke that would fetch $30,000 in the United States was worth $50,000 in Europe"...
