Firstly, the government can crack down exetremely hard on the postal system. Hypothetically, with infinite funds, they could find all the packs or atleast enough where it was more likely to be seized than not. This I believe will never happen because of the public resistance (besides fent) and lack that good old lack of infinite funding and time.
Secondly, drugs will be legalized and the economic incentives suggest buying locally, as well or moral incentives to support local buisness, and decreased risk to buyers and sellers will make the dark markets obsolete - not fully though - but in a big way.
What do you think? Will Jeff Scum of the earth Sessions along with Trump end the domestic darknet markets and decend the US into fascism or will drugs be legalized world wide in the next 5-20 years? Or none of the above? I apologize for my english, it's totally the only language I know I just suck at spelling!
There is no such thing as online drug markets. This is a role playing forum and none of us have ever received drugs through the mail that we bought off of the darknet.
