What is the Quran interpretation for psychedelic therapy since the law makes it nearly impossible to receive it?

I am aware that that there has been some scientific research on the use of psychedelic for mental disorders but other than the US, and anyway as a last resort, it seems impossible to have medical supervision for it. I have found myself (before conversion) extraordinary benefits and no side effects whatsoever of "self psychedelic therapy", managing to overcome some very serious issues such as decade long depression, addiction,... Yet, there are issues I am still working on. On the other hand traditional therapy such as psychotherapy, or prescription drugs, always failed with me. It seems the Quran doesn't talk about medical use of psychedelics but scholars interpret it the way it is "halal" if under medical supervision. **But if the medical supervision is impossible to get (for example in most or all of EU), does Quran still say it's forbidden, no matter the documented (and self experienced) benefits?**
