I think the question regarding what constitutes a conspiracy theory is a significant one.  I know in the original thread created by The Traveler, he mentioned some topics which cover the realm of conspiracy theory, but he didn't really go into detail on what truly constitutes a conspiracy theory.  Let's just say, for example, entheogens are illegal because international governments want to prohibit their citizens from expanding their consciousness and disintegrating the system.  Would one consider that a conspiracy theory?
