Just looking at risks and side effects of both medications, I think that they probably would be a bad combination.
They both raise risk of a heart attack, and Methamphetamine puts stress on blood vessels through constricting them and raising blood pressure while Ibuprofen weakens blood vessels and increases risk of bleeding.
To me this seems like a much higher chance of heart attack and burst blood vessels resulting in aneurysms, hemorrhaging, and ulcers.
