according to the article, the trade volume on silk road is around 22 million $ per year. I would hazard a guess that this is a teeny-tiny fraction of the global drug trade... and at least at this point, I wouldn't imagine it attracts any of the big players...

They are used to switching their modes of operation, diversifying and building different routes and layers into their operation.
