This ended up in a post on another forum, but I wonder what you guys think?

In my opinion DMT is one of the most dangerous psychoactive substances known to mankind.
Its potential for causing mental harm is greatly underestimated.
Many plants of the Datura genus can cause intense hallucinations similar to or more intense than those of DMT, but at least most of the people who are part of the modern drug culture are aware of their dangers and usually do not dare to ever ingest them. DMT on the other hand, in smoked form or as "Ayahuasca", seems to be the most recent hype in the drug scene and is generally regarded as "safe". The potential harmfull effects caused by DMT, especially on the mental health of the DMT-user, are rarely acknowledged and usually disregarded. At least, when a person uses Datura, they are generally aware that they were in a delusional state after the effects of the drug have worn off. With DMT, the user seems to stay in a psychotic state of delusion long after the effects have diminished and keeps being unable to differentiate between fantasy and reality. They fail to understand that their experiences were caused by a drug that messed with their brain chemistry and they come to the believe that the images that their minds created while under the influence were
somewhat real or even somehow significant.
One famous example of a person who became delusional for a prolonged period of time is "Terence McKenna (click)", whose writings are well known in the circle of DMT users. After smoking DMT he became permanently convinced that "elves" had been talking to him. And he kept propagating his believe that he could access "alternate dimensions" by using DMT.
If you look up the classic symptoms of psychosis (click), it should ring a bell and you may recognize that the delusions of Mr. McKenna would definitely fall under this category. Mental health institutions are full of people who claim to be able to talk to "fantasy creatures" which only they can perceive - because they are obviously not real and only exist in their imagination.
Here is a link to a text which further explains my ideas regarding the ridiculous state of insanity that seems to have afflicted various pioneers of the "modern psychedelic culture" (including Terence McKenna): Click here.
The mental damage caused by the use of DMT is demonstrated even more clearly by taking a look at South American shamanism.
Basically, shamans who believe they are able to interact with "spirits" are commonly regarded as being nothing more than drug-crazed psychopaths by western psychoanalysts, as they show the classic symptoms that are explained in the link above.
As an example, check out this link (click) to witness the havoc which DMT creates in the mind of an average victim of shamanistic DMT usage (in this case a National Geographic reporter) and how she starts losing herself in an imaginary fantasy world .
In various online communities one can likewise find dozens of postings that show the madness caused by DMT.
It took me about 2 minutes to find these examples of "confessions" written by DMT users:
"I became part of the energies which I will one day return to hopefully."
"DMT is by far my favorite drug and it has caused my beliefs to change drastically."
"...you are able to see the true meaning of things..."
"To anyeon but SWIMs self, the experience is quite meaningless, but to SWIM the experience holds millions of facts about the world that are invaluable to him."
"...from the first time i drank it i felt like ive simply become a channel for alien communication..."
"I began to realize how many spirits there were in the room above us. I began to converse with them, and I asked for their aide."
"I know the spirits are always there, some with bad and some with good intensions."
"My advice when dealing with either demons or "bad spirits" (which are not the same in my experience) is to know which battles to fight and which not to."
Notice how these people fail to realize their drug induced delusional state of mind even after the acute effects of the DMT have diminished.
This all reminds me of a song made by the rock band "TOOL" which deals with the same topic. It is called "Rosetta Stoned" and illustrates the inner dialogue of a DMT-crazed individual who is unable to handle the intense effects which the drug has on his fragile mind.
The person loses all common sense and believes himself to be "the chosen one" (a typical symptom of the so called
"messiah syndrome (click)"

.Here are some quotes from the lyrics:
"10 to 2 AM, X, Yogi DMT, and a box of Krispy Kremes"
"Contemplating the whole "chosen people" thingy"
"He said, "You are the Chosen One,"
"Me. The Chosen One?"
"They chose me!!!"
"And I didnt even graduate from fuckin high school."
"This is so real"
"It was so real,Like I woke up in Wonderland."
"And this wasnt all in my head."
"Such a heavy burden now to be the One"
Obviously, the lyrics describe how he/she is nothing more but a high school dropout and how he/she desperately tries to apply a "higher meaning" to his/ her life, while in reality he/she loses himself in his/her drugged out madness. Maybe this desire can serve as an explanation for the increased interest in this drug which can be observed in the present drug culture.
In conclusion, i believe that DMT has the potential to cause severe psychosis with just one single dose of the drug. The afflicted persons lose common sense to such a degree that it is impossible for them to recognize the manifestations of the harmful mental disarrangement they are striken with.
This potentially hazardous influence on the inner workings of the minds of DMT users makes it in my opinion acceptable to call DMT "one of the most dangerous psychoactive substances known to mankind".
I do find all entheogens to have potential to bring us to "Spirits" but is that bad for us to believe?
We all find these entities and these experiences to be quite "Real," and people like Terrence Mckenna spend a lot of time in this realm of knowledge.
I don't necessarily agree with this, but I do wonder what you guys think?
I mean half the reason I do DMT is because it allows you to access higher knowledge in the form of alternate realms of existence and contact with entities.
