The value of drugs for the drug smugglers has gone down a lot. it was reported that it wasn't worth as much as it was a 10 years ago. 30 billion is a lot, but theres no many cartels out there once you divide that, it aint much to run a drug organization. So they have been doing other stuff besides drugs now in days. and they have expanded to other places in the world, they have Chinese boats bringing in chemicals for them. That's why they kidnap people or why the took over the smuggling people game.
