Complete nonsense.
When China is referred to as the primary source of fentanyl, that's a reference to them as an exporter of PRECURSOR chemicals, not the finished product.
To be caught with any amount of fentanyl in China is a fast path to the death penalty, They leave fentanyl manufacturing to others outside the country and stick to the safe and profitable precursor business.
Clearly a hoax by some Bama level intellect trying to exploit people's vague understanding of the connection between China and fentanyl.
