I guess. But I'm super involved in psychedelic/neuroscience circles and I've never heard anyone call Mushrooms acid (Because 'acid' came from the lysergic acid in lysergic acid diethylamide 🤓)
...yeah, you have a point. Yet more considering Arvo, Rune, Bjorn and other characters count as a "psychedelic/neuroscience circle". xP BUT most of us are not in those circles, so... maybe they called the trip "acid" to get what they're talking about. xP
