I'm in the process of refining my experience of being high off pot. Before it made me absolutely useless. But I'm tackling more and more with the fact that because my perception of time slows down, I don't slow down with it and can actually access a lot more of my intellect and ideas while in that state. It's like I can see (intuitively) my thoughts more objectively as they arise, because I somehow become a referent looking at my own intellect as itself an object of thought. It allows me to be more critical of my own ideas and think differently than when I'm sober. It's because this self-referent is moving faster in time than the objects of my thought and I can more easily "catch" them and analyze them.
