Honestly, when i was battling my issues with coke this was the furthest thought from my mind, and is probably very similar to most other users. I genuinely didn't give a single fuck where it was coming from so long as it was coming to me.
As part of my recovery I've looked into the actual production and distribution of cocaine as a way of educating myself and hopefully building up that level of guilt so that should the urge to re-use become too strong I can use this information as another tool to say no.
The whole production, distribution and everything else that goes on with all drugs, especially coke is absolutely terrifying.
I'll certainly be picking up this book to get another slant on it. Thanks for bringing this to my attention and everything else you've helped with.
