But I think there are some serious risks to heavy, prolonged use that probably aren't well-studied or understood. Also for all I know her problems stem from the acid and not the shrooms.
I’m all for people trying them but the effects shouldn’t be underestimated. I’ve had powerful feelings of anxiety, love, euphoria, mania or sadness on different times. Very different from pot which has a pretty uniform and predictable effect on me.
Cannabis is quite a powerful drug for many. A lot more powerful than most "hard drugs" like stimulants, empatogens, opioids or sedatives, which don't "mind fuck" at all unless you do them days on end or ridiculous dosages.
No one is getting ego-death and dimensional transcendence from ripping dabs of THC concentrate all night. Just lots of paranoia and distress.
Its distressing to spill your coffee. It's also distressing to have your house burn down. The difference is large.
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.
Acid also stimulates dopamine receptors, so this could be similar to amphetamine psychosis.
