IDK I've eaten a bunch esp strong hits from the 40th anniversary summer and massive amounts of mush. Both are strong in different ways. A really strong mushroom trip is like you're on the verge of just zoning out and you can most definitely see things that just aren't there, but things seem blurred and out of focus. An LSD trip is similar however the visual hallucinations are sharp and crisp. The detail you can acquire in visuals from LSD is unmatched IMO. LSD is only the strongest drug by quantity. The concensus is that qualitatively the strongest psychedelic is DMT.
