It is very much not the homeopathy of psychedelics. Homeopathic medicine is where you dramatically dilute the medicine to the point where there's no appreciable amount of active medicine in the dose. There's some theory that the water molecules "remember" the medicine, or some such stupid bullshit. A microdose of psychedelics (for example,
https://thethirdwave.co/microdosing-lsd-mushrooms/) is misnamed. It's about 1/10 of a normal trip (a decidose?) Enough to feel buzzed, not enough to blast off into outer space.
As a matter of fact, I took a microdose of shrooms an hour ago. I don't need to blind my dose, I can tell when I'm buzzed. I'm not arguing that it's noticeably improving my intelligence, performance, stamina, or anything, but it is most definitely making my afternoon more enjoyable.
