I definitely agree it would be very nice to know more about the exact functioning of psychedelics - and about brain function in general. It's true we don't know 'a lot' right now. However it's also true that we know a lot more than most people think. For example, we have a fairly clear idea which brain receptors are targeted (for most tryptamines, that's 5-HT2a, 5-HT2c and 5-HT1a; but for LSD, add in another 5 HT subtypes and then quite a few others on top) and we have a reasonable idea of the 'normal' purpose of these receptors.
There have been fMRI scans performed on people taking psychedelics (sadly only mescaline and psilocybin to date; I'm really looking forward to when someone does an LSD study) and we get a reasonably good picture of which brain areas experience differences in activation. And again, we also have a reasonable idea of what brain areas are responsible for what parts of cognition.
We do still have a lot of guesswork, that's true; but it's not all mystery.
I'm glad you survived your experiments and are a functional individual. I just hope you don't accidently destroy the lives of too many gullible people.
I've heard plenty of anecdotes of people having their lives destroyed by psychedelics, but have yet to find any actual evidence of it. In the medical literature there is a total of one case known of a person that did not previously have a mental illness experiencing a lasting psychosis after LSD use (out of hundreds of thousands of recorded LSD experiments). That person was the twin of a schizophrenic, and so may have had an undiagnosed condition. Out of people with pre-existing mental conditions, the rate of a lasting psychosis following an LSD experience is around 0.2%.
There certainly are cases of psychedelic use that have cause problems in other ways, such as the CIA's internal experiments dosing people with LSD causing one employee (who was given a high dose in his coffee without his knowledge) to commit suicide in a fit of paranoia; however I discount these as being true dangers of psychedelics as being dosed without your knowledge is a very different thing to taking it with (at least some) foreknowledge and expectation of the effects.
My book focuses - as the title states - on the responsible use of LSD. I don't deny that it can be a very traumatic and unhelpful experience when used in the incorrect setting or with an incorrect prior state of mind. I also don't deny that even with the right setting and state of mind it can be traumatic - but in these cases, the traumatic experience can be directed to be useful (I specifically cover this in book in quite some detail) in the same way that people coming through a difficult life experience such as a car accident, death of a loved one, or similar can come out of it stronger and better than they were before.
At no point does my book advocate the use of LSD to 'go out and have fun' or as a 'party drug'. It certainly can be used this way (and often is) but personally I see too much danger there to consider that wise.
