Comparing high dose THC to light-moderate dose shrooms/acid isn't a totally straight comparison.

No one is getting ego-death and dimensional transcendence from ripping dabs of THC concentrate all night. Just lots of paranoia and distress.

'ego-death and dimensional transcendence' and 'lots of paranoia and distress' just sound like different framings of what could be remarkably similar psychic states.

Having been in both, they are worlds apart. Sure, those descriptors might be tossed around, but that's a short commming of English to properly convey experiences.

Its distressing to spill your coffee. It's also distressing to have your house burn down. The difference is large.

Nothing wrong with experiences like what are called ego-death and dimensional transcendence if it doesn't involve paranoia or distress. Especially with dissociatives these are often the goal, and are quite pleasant.

The THC induced paranoia and distress are usually due to effects like time-dilation, memory impairment, depersonalization, thought loops etc, which I'd put into more or less same category as you get from psychedelics or dissociatives.

Plenty of bad trips with quite low doses of THC too: https://erowid.org/experiences/exp.php?ID=70884

I think the "hardness" of different drugs, especially in how strong the effect is, is mostly a cultural and legal artifact that doesn't really correlate that much with the actual experience.

This is exactly my experience. I almost never smoke weed, and only do when I'm in a comfortable place and among friends. Shrooms is more of a mid-level body/sensory experience for me, whereas pot is a deep dark journey into the recesses of my psyche.
