NO! Do not use the microwave! Horrible Idea, but you may be on to something with the Weed Smore Idea. I just made about 20 Weed/Nutella crackers and they work like black magic!
I think you could still do weed smores, only put nutella then weed one a cracker, then nutella with marshmellows on the other cracker, stick them together and then wrap the whole thing in tin foil. Bake them in the oven at 320 degrees farrenheit for 22 minutes. It doesn't smell too bad because it's wrapped in tin foil (when you open it definitely smells and the final product smells).

Trust me! It works. Nutella and weed is a really easy way to make a weedbutter (very spreadable!)

Try it out! Start with about half a gram in nutella and marshmellows on grahm crackers. I think I might!
