By all means decriminalize these drugs. It's a shame they were ever made illegal in the first place.

But don't get confused about what's really going on.

"Set and Setting" https://en.wikipedia.org/wiki/Set_and_setting

"Of course, the drug dose does not produce the transcendent experience. It merely acts as a chemical key..." — Timothy Leary (who ought to know.)

These drugs are like whacking the brain upside the head chemically. For most of us that's fun, but it's a crap shoot. "Bad trips" are a thing.

The possibilities for precision therapeutic techniques are in the creation of the set and setting, through structured storytelling.

(Not to make it about me but I did some psychedelics back in the day and they did not cure my depression but hypnotherapy did. YMMV.)
