#2LSD also increases activity of that fractal dimension.

#3Why is it even legal to conduct LSD experiments? There was some animal testing post earlier, but giving people illegal consciousness altering drugs seems so much worse.

#4Well, yes, adding noise increases the fractal dimension of a signal.
"Shannon entropy" is noise.
"Lempel-Ziv complexity" is "how long is the zip file".

#5Here is interesting study lecture and article, maybe somewhat related.
The Geometry and objects of things you see in typical to DMT experiences are hyperbolic.

Interesting. What do you mean by zip file?

I'll take the bait. A drug being regulated by narcotics regulation does not mean that its use has to be completely forbidden. Just because Average Joe is not allowed to do something does not mean that there might not be professionals who are. Opiates for example are both regulated and used for pain treatment.
Any study with human participants has to go through an ethics review and the participants have to be both informed about the goals of the study, possible risks and consequences of the procedures and also have to take part voluntarily. (Regarding "consequences": a brain scan could e.g. show a medical condition and having knowledge of that condition would mean that the participant would have to state this as existing condition in the future whenever they wanted to sign up for health insurance for example. So: it is complicated!).
The Helsinki Declaration contains ethical principles on human experimentation if you want to have a look: https://en.wikipedia.org/wiki/Declaration_of_Helsinki

Why are they illegal to begin with?

People have a choice.

I would assume the people taking these drugs in a modern study would be participating having given their consent and under the supervision of an ethics review board. I’ve never taken LSD in my life but I would be willing to participate in a study like this and I can’t imagine I’m alone.
