It can be shown without a doubt that the CIA, the Mossad and British intelligence run about 70% of the world's drug supply.
Then show it.
Then show it.

Once you're convinced of the estimated value...start using your own logic. The value of the market is absolutely tremendous. If you don't think that the ruling powers that run the governments around the world don't want a piece of that action, you'd better think again.
So. If you can show it, then show it. If you can't, then don't say you can. Instead say "I have no actual evidence to backup this claim, but my theory is..."
Also, to White_N_Nerdy, before you go 'look at how much it's worth, they MUST want that and are therefore involved'- consider that the USA GDP is 15 trillion dollars. There's no way our government could control the entire drug trade, which means a fraction of 500 billion is the best they could do, and what's a chunk of 500 billion to the US gov't? Besides, is a chunk of 500 billion actually worth the risk of the ENTIRE WORLD discovering our government is the most evil and corrupt organization ever to walk the earth? (not that they are, but they would be if they were orchestrating the entire drug trade)
America is the land of the free (for all). I consider the steady-state employment of government powers at the federal level nothing more than a score board on a death match server.
Do it yourself. I'm not here to hold your hand. I'm not making any arguments, I'm telling you what I know for a fact. I gave you some links, you can start there.
