If we think of this logically - Heating the weed in the oven is exactly the same as putting a lighter to it. As soon as it burns, it's obviously been heated - so why the oven? I dont buy into it at all. Maybe it works, maybe it's bullshit. Maybe people think it works because they want it to. As far as im concerned - bullshit, but i could very well be wrong. I just dont care.
