There’s more evidence it is than it’s not. And, yes, even people who have been super stubbornly against psychedelics only very seldom come to regret taking some. Which you cannot say for other recreational or sedating stuff at all.
According to the GPTs, the LSD ranks the bottom in the chart of ‘damage done to your organism’ while alcohol tops it every time.
While using GPTs to explore my own bias, I liked the re-phrasing "the chemical opens a window so that the profoundly human experience of care, safety, and novel emotion can finally get through to a brain that had walled itself off".
Highlighting how the human experience is an intrinsic part of the benefit seen, but not the only part.
(and I totally agree with you, alcohol is one of the strongest and also one of the less pleasant - both in withdrawal and in long term health impact, not to mention social harm - recreational things that I or people-that-I-know-well have ever tried)
At the same time, using LSD once is higher risk than one night of drinking.
