I was just thinking that if your became a drug dealer and used DNM's as your main supply how big could you go.
I imagine not very as it would become obvious very quickly and you would need a few different houses that your product could be shipped to. Also it would also be not always reliable as customs could seize a big order witch would be a big problem.
Anyway what are you opinions on this?
Customs is always a problem when importing drugs. If your operation gets too big for regular mail, then you could setup guys in the foreign country, get it domestically and send it in a shipping container with your own custom stealth. I think getting 1kg of coke/mdma/heroin per week is manageable through regular mail though. You just need to setup your structure so if a package gets snatched it won't be a problem for you legally and financially.
