Why 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.

Psychedelics are a tool. You don’t ban powerful lasers because someone might get hurt. You regulate and prescribe how they may be used safely. And they are a very powerful tool, not only as a medicine to treat addiction and depression but also as a lens to inspect the nature of consciousness.

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

Interesting. What do you mean by zip file?

Lempel-Ziv compression is used by some file compression utilities.[1] The ratio of original size to compressed size is essentially the Lempel-Ziv complexity. If you compress a file of AAAAAAAA..., you will get a very small file, and a low complexity. If you compress a file of random numbers, the file will not compress much, if at all, and you get a high complexity.

"Lempel-Ziv complexity is the number of different sub-strings (or sub-words) encountered as the binary sequence is viewed as a stream (from left to right)"[2] This leads to a compression algorithm.

It is all explained in the paper, they had all the necessary licences.

One noteworthy point is that they only took sane adults with experience in psychedelics (that's the tl;dr).

There is lots of potential benefits that far outweigh any downsides,so it's worth investigating. They were made illegal for political reasons rather than for scientific or evidence based reasons

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

You should consider submitting that second link as its own story. Excellent content.

Sources for benefits (plural) vs. downsides? Source for politically-motivated criminalization?

"giving people illegal consciousness altering drugs seems so much worse"

It would be interesting to learn why you think it would be so bad.

Does listening to white noise increase the fractal dimension the same way as drugs?

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 inf…

You have to understand that because animals borrowed cell signaling form plants that most transmitter blockers and analogues can be found plant cell signal chemicals

Or to put in broad terms our brains are powered by degrees of getting high. Its more of the degree and method that produces bad social results

>but giving people illegal consciousness altering drugs seems so much worse.

Why do you think so?
