Erowid.org.

Textbooks don't really exist about this stuff, unless you're like a pharmacology student and reading at that level.

Erowid also has free versions of PiHKAL and TiHKAL, Alexander Shulgin's two books which are fucking awesome

I would take whatever this wall-of-text person is saying with a grain of salt. Erowid, in and of itself, isn't a scientific source, but if you go to a page for any specific chemical, you'll find a list of links that include scientific studies in journals, etc. as well as primary sources like experiences.

This person is an unreliable source fr information on LSD.

You know there isn't much in a single location aside from Wikipedia.

In textbooks I've come across , there is discussion of the pharmacology properties or a brief note about counter culture and general effects.

There is limited research on the drug as it's been black listed for almost 50 years and even now, it's primarily only researched for terminally ill people/mental health. Only a handful of those studies exist and none use double blind controls so the science quality is poor.

I myself am not convinced it has mental health benefits due to the way the drug works. It does however have strong suggestive effects meaning the drug itself promotes placebo/expectation effects.

The lecture I put together for my class (perception and sensation ) pulled info from a wide range of resources.

However there is one organization trying it's best to do modern research and they have done some MRI studies. There was also a study on LSD and synesthesia which sheds a lot of light into the mechanisms. MAPS is the organization. https://maps.org/

They have videos on YouTube with researchers discussing the research and studies they have done. But they mostly focus (last few years at least) on it's use in mental health.

The drug property information I know about is mostly pulled from old research from the 60s before the research bans. A lot was done on animals to understand dosage and half life. The cascade effects of how this drug works are still not really understood. We do know that the drug is similar in structure to serotonin. But there are still a lot of unknowns.

Let me dig around for my resource links. I have a few interesting studies I found when preparing the lecture, including the synesthesia one, and I'll organize it all and I'll put a link up to a g drive with it.

The lecture I did was 3 hrs long about hallucinations with a chunk dedicated to psychedelics. It did rely on other lecture materials to understand or otherwise id just put it up. (It was the final lecture for the class so it referred back multiple times to previous lessons). But maybe I can re-write it a bit. I've honestly been thinking of turning it into a video for a while because there are so few resources out there that review it more broadly. And a hell of a lot of misinformation about hallucinations and psychedelics.

Basically this lecture was on hallucinations and the primary causes and how each of these causes relies on the same root changes in brain processing.

For instance. You are driving on a country road at night. Vigilant to look for deer. Multiple times you were sure you saw an animal near the road but soon realized it was a fence post. Or an old glass bottle reflecting your headlamps. But for a split moment you did see an animal there before you corrected the perception.

What ultimately caused that is what causes hallucinations in other situations. Like schizophrenia and drug use.

So we circle around neuroscience, psychiatry, physiology, and pharmacology. As well as cultural impacts influencing the experience of hallucinations or psychedelics.

This is getting long. Apologies. The lecture is 3 hrs and relies on many other hours of information. It's a big topic.
