I mean here are some reasonings, and relatabilities:
-Parents tell their children don't do drugs usually without giving them a seemingly valid reason not to
You assume that Adam did not understand. God is not like fallen mankind. He is just and fair. Adam understood the consequences, but had not yet experienced the consequences.
-when Adam ate the fruit his eyes were opened. (Whether literally metaphorically or dilated (not that there is much of a difference) it's still pretty evident)
Being a fruit that helps them to know the difference of good and evil does not mean as a psychedelic. Frankly, I believe God fully intended for them to eat of this tree after they had proven themselves as fully faithful to God.
-the fruit created a paranoia effect
Knowing they disobeyed and would suffer consequences is not paranoia. Paranoia is an irrational fear of everyone. There fear was rational.
-it angered the Father that they disobeyed and they were cast out of the garden
The wrath of man is not the same as the wrath of God. There is no reason to believe God was angry - disappointed, yes, but not angry. He gave them hope of salvation in Genesis 3:15, and provided them temporary cover with the animal skins. He cast them out to prevent them from eating from the tree of life so they would not become immortal sinners. That is not anger, that is hospice care.
-the serpent tempted eve much like a drug dealer might tempt someone to take acid or mushrooms claiming it's the best thing ever
Just because drug dealers tempt people to buy drugs, is not a fair comparison to the serpent. They were tempted in the lust of the flesh, lust of the eyes and the pride of life just like all of us are in so many other arenas. Jesus had the same temptations.
-it seemed to cause them to feel naked when before they never seemed noticed, just as drugs might cause someone to toil in what seems like vanity to an outside source
They felt naked because the the shekinah glory of God that had covered them departed.
-Adam and eve seemed lost
They were lost in sin. If you compare psychedelics to sin, perhaps it is because sin is a form of insanity, of which psychedelics increase.
-psycadelics seem to be forbidden... atleast to most people
Because is it is illegal and destructive. Do you equate something forbidden as the reason for temptation?
So is there any reason to believe the forbidden fruit was not a psycadelics drug, and preachers just don't put emphasis on it as such as to keep it in ancient context that they don't anger the world?
Yes, every reason. If it were, we would all be born hallucinating and could not comprehend anything.
