I like the idea of psychedelics being free to use but only in recognised centers or "retreats", under professional guidance
Holland did the OTC experiment already and there must be interesting data about this somewhere. I don't think OTC would be a good idea, maybe I'm just overly cautious.
At the moment, anyone with sufficient motivation can get psychedelics at the click of a button and here in W-Europe nobody will really face any serious legal consequences for personal use. Testing kits are widely available. The current situation is not a bad one.

I don't think (bad) trips would cause much social harm at all actually. Psychedelics have an unpredictability to them that warrants caution in a way that doesn't apply to alcohol (or sky diving, rock climbing ...)
Medical prescriptions are required (in part) because of the potential side effects. If 1% of all paracetamols would drag the person through a mental hell scape, it wouldn't be available OTC either.
Just some thoughts, the discussion is a difficult one.
