Are we talking STONED as in drunk or high on marijuana?
Are we talking HIGH as in COCAINE?
Those are two very different types of altered states and need to be carefully dissected.
What I saw was not a person high on speed of any sort, nor did I see a person stoned at all.
What I saw was a person being out classed with an amazing amount of facts and data who had no idea where those facts came from. In other words, he was totally over whelmed with data he should have known intimately being the most powerful man on earth, but he wasn’t!
He turned out to be a STONE cold fake, HIGH on his position!
My guess would be freebase/cocaine use. The same stuff that did Whitney Houston in. He has admitted to using it in the past. It’s the sort of thing that he doesn’t need to be doing everyday but more or less going on binges every now and then when the pressure is too much.
