Ja som overskriften siger, så vil jeg høre om der er nogen som har nyere viden på dette område.

fra Sacred Mushroom of Visions: Teonanácatl (2004); Baeocystin and norbaeocystin were first identified from Psilocybe baeocystis (leung & Paul 1968). Baeocystin has since been found in at least 26 species of mushrooms and there is one report that it is psychoactive in human doses of approximately 10 mg, ingested orally (Ott 1993). Unfortunately, sufficient data are not available for these two compounds to asses their clinical properties, but it is very likely that they produce qualitatively different psychopharmacological effects. Based on current neurochemical knowledge, one could reasonably speculate that these two compounds would have different affinities and abilities to activate the various brain receptors relevant to the actions of entheogens. Therefore, the relative proportions of psilocybin and baeocystin in a particular species of mushroom are probably relevant to its effects after ingestion. This idea would be consistent with anecdotal reports that some species of mushroom, for example P. cubensis and P. azurescens, can induce qualitatively different effects.
Et andet sted i bogen skriver han:
Citat:
Psilocybe semilanceata is known as the "liberty cap" mushroom. It is the most common species sought after by psilophorian enthusiasts for its tranquil effects.
semilanceata indeholder en betydelig mængde beaocystin. Tranquil? Ud fra mine egne få oplevelser med cubensis og semilanceata, kan jeg ikke umiddelbart se at semilanceata skulle være mere beroligende. Jeg har kun trippet 3 gange i alt, så slet ikke nok til at jeg kan sige noget om en tendens, men alligevel synes jeg at semilanceata giver et gladere trip med mere tankespind. Jeg morerede mig i hvert fald gevaldigt over de krumspring mine tanker lavede. Måske et lidt mere hyggeligt trip?
Har i andre kilder i denne henseende eller personlige oplevelser som er relevante, så kom på banen.
En god introduktionsbog til Psilocybin-svampe iøvrigt. Manden var jo med i Harvard forsøgene sammen med Timothy Leary, så han er blandt de mest vidende vesterlændinge på området. Bare spring over alt hans New Age-crap!
