i already get over 100% fiber in a day and have a cup of coffee in the morning, a cig after that would blow my ass inside out. but it can be good. weed + coffee is better, for obvious reasons, but also the flavors.
anyway, the answer is water or red bull/energy drink or cheap beer. Anything else, I don't want to fuck up the flavor with, but if I'm already drunk then that rule goes out the window.
