When I refer to chronic, I just mean weed. Not necessarily coke+weed. From my experience, sprinkling blow on a bowl is a waste of the stuff, and the problem is your bowl will have coke resin on it. I don't mess around with coke anymore, but it's definately a waste to put it on your bowl. But I guess if you've got lots of powder it's fun to sprinkle it into a blunt and make it a wu-banger.
