I'm not in a position to comment. I don't have information on how many superlabs there may be.
With regard to my personal experience and opinion as to the persistence of fentanyl trafficking and the continued flow of it, I would say the simplest explanation is that there is a market for it. There is an appetite for it. Someone will always find a way to feed that appetite, just as there's a drive to accommodate any sort of illicit product. I think that's why there has been a heavy focus on fentanyl in the last, probably, five or so years. It's small and very profitable.
