There is a miniscule amount of trichs on your stems, so you can catch a buzz if you smoke enough of them, but the smoke is harsh, and tastes/smells absolutely disgusting. I actually was in your situation last night, chopped up a bunch of stems, smoked a bowl of them, and stopped because it was disgusting. And I can go a night or two without weed. You should be able to as well. Do it just to prove to yourself you can, and to lower your tolerance until you get some cash together.
