I think it's more important and constructive to take note of what I do with my thoughts rather than the content of my thoughts when I'm high.
I sometimes think of a deep philosophical concept, and like for example "Things are just so complicated!" and then my mind verifies this idea by going "COMPLICATED!" in a cartoon character way. Like, I verify things with impressions.
I can think of an area in my body and the nerves there will go crazy with the tingling, movement sensation that pot gives them. This is useful for when I'm trying to remember if my sunglasses are on my head like I am now!!!!
Basically my theory of thought, how thoughts work for me, is that I have so many thoughts and sensations that I try to fit the ocean of sensitivity to ideas that I have through a very small hole which is expression.
And as specific thoughts accumulate into less specific thought (because 100 percent specificity is impossible)they also collect power as I try to imply the deeper, microscopic impulses that are being crammed into this expression. What happens is people think I'm reacting strongly to one thing when really I'm trying to get around a deeper and more prevalent thing I want to express.
