There is actually a large amount of research trying to take psychoactive / psychedelic molecules to derive analogues without the mind altering side effects. As some have explained to me, it’s that we aren’t 100% sure if it is chemical alterations or the experiences themselves (probably both) that elicit positive therapeutic benefits, and so a theoretical hierarchy of medical treatment depending on issue would go like 1. Consultation, 2. Prescription of non-psychoactive analogue, 3. Professionally guided treatment with psychoactive drug.

Though with cannabis you wouldn’t need the professional guidance with 3 in any situation, and this is more relative to psychedelics. It’s a really interesting time either way tho
