People say this about Mexico bringing heroin in.
There is a novel called "Red Winter, White Snow" where drug sellers in general bring foreign narcotics in to hurt the USA.
I followed some conversation where it was talked about that the
Opium wars were fought and brought opium into China. I don't know if this is true or not. I have heard that during World War II, some of our US sailors saw a bunch of the Chinese smoking opium. I have no idea.
Though the tally of fatalities is given in the article by those using the opioids, I've also heard 200, a huge number, OD on it daily, I guess, most survive, but this shows the problem.
Quote from the wiki article above:
The victorious British were successful in inducing an opioid crisis in China, which seriously undermined Chinese society.
That is pretty bad everyone, then, in the 1920s, there was a market for opium in the US, opium dens as there were back in the day. We need to get onto this crisis.
