"There's one white powder which is by far the most lethal known. It's called sugar. If you look at the history of imperialism, a lot of it has to do with that. A lot of the imperial conquest, say in the Caribbean, set up a kind of a network... The Caribbean back in the 18th century was a soft drug producer: sugar, rum, tobacco, chocolate. And in order to do it, they had to enslave Africans, and it was done largely to pacify working people in England who were being driven into awful circumstances by the early industrial revolution. That's why so many wars took place around the Caribbean."
