I like to view THC as performing a natural transformation to the attention mechanism in the brain so attention per unit time is more distributed among all modules, and thus more combinatorial interesting things can arise. (I’m still in the midst of foramlizing a mathematical model from a PLT perspective.)
But one noticable downside to it is that the more distributed the attentions are, the more likely you are to get stuck in a local maximum as the less cohesive your modules become in terms of utilization (eg for abstracted goals) and the data-granularity gets too fine-grained to be useful from a cybernetic perspective.
The effect differs from person to person. (Eg Short-timespan-wise people lie on the sofa or keep laughing, etc, the stereotypical notion being “stoned”, and long-term-wise if things are repeated in the same settings over, reliance is formed (as a coping mechanism for stress perhaps) and person becomes a typical unproductive “stoner”))
Therefore the most important thing here are 1. the settings 2. Don’t take it lightly. Though thc is not as powerful a disruption to the default mode network as lsd/dmt, one should never take it mindlessly and too regularly. Learn to grow out of it, not in.
