Also, I've never smoked pot, but I've been in these remarkable half sleep/half awake states, sometimes up to a half hour (there are similar brainwaves between that state and ones induced by marijuana). What I've found is that in those states, answers did come really quickly to me. There was a satisfying sense of insight and understanding. There's only one problem. All my decisions made no sense at all. Once I was awake, it occured to me that I was thinking total gibberish. I've talked to people have been stoned, and people that were stoned, and it seems to me that they had the same problem.
