Actually there's some classic Mail reporting going on here:
We are twice told that this is a "huge haul" to build up the image of sacks of the stuff in your head.
then about half way down we get the numbers:
Court documents revealed that Mr Rausing was charged with possessing 0.2oz of crack cocaine, 0.1oz of heroin and almost 1.8oz of cocaine
The amount of cocaine found is enough to normally justify an "intent to supply" charge but it's not exactly a scene from "Scarface"
