I'm with SmokinOkie. As little wood as you need in one of Cookshack's electric smokers (2-4oz per cook), and how inexepensive a box of wood from Cookshack or even Charcoalstore.com can be. You are only talking 50 cents or less per smoke on average for cost of wood. Why would you want to take a chance with possibly unsafe wood on that $15-$$$$ load of meat?
