The myths about psychedelics have remained pretty much the same since the 60`s, I wonder why, with all the research and all the people who have taken them, that they havent been debunked yet?
There is simply no physical way that lsd can make you think you are an organge, or peel your face off, unless you are allready have an affinity for the psychotic, or schizophrenic state of the mind, then surely any strong experience can trigger such illness or unfortunate events.
I myself have only taken LSD only once, but having taken over 200 trips on psilocibin in everything from level 1 trips(everything just gets lighter, more colourfull and giggly), to level 4 trips(having your ego torn to shreds, a feeling of omipotence, esp etc), I would say I`m "fine", and as a person with a cynical outlook on life, even a "badtrip" doesnt have to be bad, It can give you an enormous graditude to just be alive.
The halucinogenic properties of these substances are ofcourse dose specific, but speaking for myself it is rare to see anything but objects breathing or morphing, twisting or turning, or other "mild" visual phenomena as tracers etc
Granted I have seen more "incredible" things, but this is usually at a dosage that produces very uncomfortable "bodyload".
I am no psychedelic zealot , I am no Hippie, I`m not recomending this to everybody on planet earth, in fact a lot of people should stay away, these myths never cease to amuse me.
