Here are stellar renegade's notes on this:
Whatever drug you're taking physically, forcibly causes you to act and percieve in a certain way. It's not a preference like OneWithSoul said, you have to act and percieve that way regardless. Whereas with personality it comes straight out of you from the deepest recess of your soul. When I said that the state of robotripping I'm in now might resemble what your life is like, I meant in a loosely associative way, not something that's exactly the same. You're only that way because of your emotions and preferences, etc, whereas this is uncontrollable (but fun!)
Now, I will say that this particular drug doesn't make you feel hazy. It actually can clear your head a good deal. But yes, your thoughts are stunted. You can only go so far, but what you do think is either really clear or overly simplified to the point of being dumb sometimes (and even unrealistic sometimes, though I'm still pretty realistic while under the influence). But it's not a bunch of jumbled tiny fragments of thought, in my experience. It tends to wipe those away.
One of the things we like to do is create images with our hands. You can't really see anything but you can imagine it being there. Like, we played chess for a couple of moves, and I could actually imagine where the pawns were being placed where ordinarily I wouldn't be able to hold onto that thought with my mind.
Your mind does seem to hop from one thing to another so to speak, but at the same time you don't seem to care or really notice even. You're so caught up in the fantastic experience of it that you just go with it. I'd say that it's easier to forcibly think than it is under the influence of weed, though. It's like things are simpler, more forcible, yet rapidly moving and trailing when on this particular substance. But when some other object comes to your attention it distracts you, so your mind does hop around but it's different than pot where your mind just trails.
Weed does something completely different. It's similar in ways but on the opposite end of the scale as far as firmness/looseness goes, for instance. So it's not like every drug out there is gonna make me feel like an INFJ, and the basic effects are usually pretty universal for everyone anyway.
Sorry about your theory. There might be a little something to the thought but overall it doesn't quite hold up.
