It takes a little getting used to this idea so it's worth repeating once a day till it sticks in the episodic memory and/or long term memory. The idea that the secret services (including MI6 I can add) run the global drug trade sounds like the sort of thing the corporate media would smear as a conspiracy theory to teach the gullible public what to question and what not to question.
Anyway here it is and I can talk at length about this subject but it's quite far down the list of real secrets. The spooks sell drugs to fund their black operations. Those are the real secrets if you dig around a bit. Particularly the tech end that keeps us reliant on oil and the conflict that arises from it.
