The one thing that the US has consistently shown recently is for every state that has legalized or decriminalized/medicinal marijuana, opioid abuse and related deaths have plummeted, yet we have trump trying to crack down on this emerging trend.
So it's just more of say one thing but do another.
They are basically saying porn, social media, the news hype cycle are all tied to dopamine increase in your brain. Its the same mechanisms that drugs, alcohol,cigs can produce.

The Century of Humiliation started them on a road of weakness that took several revolutions to figure out how to stop. Only with Deng Xiaoping in the 80s did China begin to find its stride, and only now are they starting to finally become a world power that the world needs to reckon with instead of ignore. Whatever you think of politics and philosophies, China is now considered a world power in a way it never has been before.
Of course explaining that by opioids alone would be balancing between a huge oversimplification and a plain lie, but at least opioids have been the biggest single factor.
E.g. Another way for a country to lose the #1 economy spot is for it to simply stay the same while other nations (e.g. Europe in this case) make huge advances.
Being fair, a few other things happened in there too. I don't think that during the communists' Cultural Revolution the country was primarily being held back by opiod abuse.
If such a relatively innocent thing as inhaling lead vapours from suddenly omnipresent cars in 1960s and 1970s could cause a 1980s-1990s crime wave in the U.S., it is easy to see what putting whole nation on opioids could do with the next generation.
In the scheme of a 1000 years of history you could argue 1970 counts as only now perhaps.
