The only thing worse then cutting your coke is LYING and saying you cut your coke FOR PERSONAL USE... c'mon, just admit that you're trying to increase profits by fucking others...
Oh yeah, if you feel your question has still not been answered, I will tell you - cut your coke with meth!

"I am not one of those weak-spirited, sappy Americans who want to be liked by all the people around them. I don't care if people hate my guts; I assume most of them do. The important question is: 'What are they in a position to do about it?'" (William S. Burroughs)
