The profit structure of heroin to cocaine is completely different. With heroin you can literally 'step' on it and create 15 kilos or more from 1 kilo. And the profit on the retail level 100 times more. to receive 5% pure heroin and 95% cut in a $25 bag of junk is enough to OD a junkie.
The profit on cocaine is no where near that. You cannot even cut cocaine 1 full time, to make 2 kilos from 1. The product would be destroyed.
5 kilos of junk sold properly could turn a guy into an instant millionaire and more. 5 kilos of cocaine could earn a guy a net profit of a few hundred thousand. "maybe"
Yes, this is why its necessary to have contacts in the source countries. THATS really how you make the big money in coke.... by sourcing it for 5-7 bucks a gram, and selli.g for 30- 50 a gram wholesale....
