Illegal narcotics is over a half trillion dollar a year industry. Most of the cash(90%) winds up in western banks and the stock market. The US loves the drug trade. It is a major contributor to keeping the system going.

Mexico’s number one export, oil, from Cantarell is falling fast, like 18% a year. Soon not to be an export. I would not expect mexico or the US to crack down on drugs anytime soon. Though, I would expect the gov to crack down on where the money goes.
