I mean, I think psilocybes (and LSD!) should be fully deregulated, sure :)

However:

(1) If you trust your illicit psilocybin sources, OR already decriminalizes personal use drugs (Measure 110), so, if this isn't your cup of (psilocybin) tea, there's nothing stopping you from doing precisely what you propose.

(2) If you have a trip sitter you trust and is willing to sit with you, there's nothing stopping you from bringing them to said center. Ostensibly having someone experienced around can't hurt, and is pretty likely better than what most people are getting most of the time. Surely we can agree that it's reasonable that some people would get more out of a trip if they have professional guidance, and it's not just a safety ("is this person going to rob me/assault me") issue? Perhaps a problem is one of assumptions: I think this is set up to allow recreational use but encourage therapeutic use, coupled with the idea that therapeutic use is aided (made possible?) by the presence of trained staff.

Do you feel this way about bartenders?

At sober to moderately buzzed no, anything more yes.

are they serving hallucinogenics? Do you trip on bud light?

No, but the problem was praying state-licensed practitioners don't take advantage of you in an incapacitated state. You might not be hallucinating, but surely there's an amount of alcohol where you're just as helpless if not more than a shroom dose.

The hallucinogenic (not psychedelic) effects of bud light shouldn’t be minimized. It takes a lot more work to achieve and is pretty miserable, like 30 a night for a year, but for sure booze can make you hallucinate. It’s generally considered to be whatever the opposite of therapeutic would be.

My personal experience is heightened awareness and even increased physical strength on mushrooms. Alcohol gets me dizzy, confused, and dumb. So comparatively, I'd be more concerned about someone taking advantage of me drunk than tripping.

Like how Dr. Hannibal Lecter convinced Mason Verger to cut off his own face while on hallucinogens? Yes, there is nothing stopping a psychopath, cannibal therapist from setting up shop and doing this with a deeply troubled patient. It will be a short-lived career, though.

You...understand that was a fictional event, right? In fact it was specifically conceived by its author to be shocking, horrifying and extraordinary.

It never occurred to me that this was fiction, so thank you for helping me finally realize that.
