Yes. God didnt gave human rationality do degrade it with chemical substances.
More interesting question would be why would someone even want to have such experience in the first place? Talking to a demon would be as productive as flogging a river. Moresoever you outright answered your own question with that excerpt: You should be critical to any kind of such apparitions and have your mentor advising you. Just avoid it. Everything will be revealed after death anyways.
Is the use of psychedelics sinful?

Just because Jesus turned water into wine doesn't mean we ought to abuse the gift of alcohol that God the Father gave us. Drunkenness is still a sin.
And no alcohol is not the same as pharmakeia. Only pagans poison themselves with drugs like LSD, weed, shrooms, etc. don't give me that "but pagans didn't have MDMA, LSD, DMT and other hard drugs" you know very well if the technology existed back than they would be using that as well.
You can't sanitize water or equipment with weed or shrooms.

A common answer on this board is that drugs count as witchcraft, because the word for witchcraft used in the Bible is the word we derived "pharmacy" from.
