Is this the revenge of the Chinese for the opium trade? I am not sure I clearly see the connection, but the thought crossed my mind.
Discussion
The three main psychoactive alkaloids in opium are morphine, codeine, and fentanyl.
The west attempted to subjugate the Chinese with the opium trade in the mid 1800s.
Today, the vast majority of pills and powder produced in Mexican drug labs are produced from Chinese fentanyl.
Revenge? Maybe. You decide.
