Personally, no, though I admit it is on my relatively immediate "to-do" list. I have a lot of friends who have, and I've taken a particular interest in this drug so I've been getting feedback from as many experts as I can. These 'experts' could be experienced practitioners my age, non-drug consuming doctors with 30+ years of experience, drug consuming elders from many different walks of life, etc.

The following is a compendium of all of the things that I've been told about the drug. This of course means some of the information will be contradictory, it came from many different sources:

First, the early onset effects. With light dosages some people account seeing waves of color and energy flowing between everything, especially living things. To be clear, as explained to me this isn't a "I think I might be seeing some lights guys" type of experience, but instead very vivid and impossible to ignore.

In this stage there are common reports of being able to feel other's emotions, know the topic someone is thinking about, etc. Note that this line is meant to read as it says. They explain to me that you can't hear word for word what people are saying, nor "see" their thoughts or anything like that. Instead, if you relax your mind and focus on them your own thoughts will go to the closest topic you can in your own mind that relates to their thoughts.

The above is why I believe that "direct channeling" is limited by the consciousness of the 'channel' or 'host', leaving the 'speaker' or 'outsider' from being able to convey any messages that are outside of the understanding of the host, but I'll save my metaphysical theories for another time. ^_^

"Unconscious trips" or "Out of world trips", when you use enough to fully hallucinate your surroundings, are often stories similar to an Alice in Wonderland type of experience. Encounters with foreign entities is common, though they are often more akin to a fairy tale creature than an alien sci-fi creature. These aliens almost always share life secrets with 'the traveler [you]'. These stories vary from individual to individual, but common themes often persist even in people who do not know each other and have no reason to have similar thought processes. People [often with no prior belief or interest in aliens] being told that humans are the result of genetic experiments involving many intergalactic species is one story that is heard regularly. Other things include that humans are descendent's of ancient alien civilizations that destroyed the rest of the universe, humans are an extremely powerful psionic sage-like race is another.

One individual gave me a very interesting explanation of the drug and the feelings it causes. She describes it as an "instant road to sanity." She says it puts life into perspective, and helps 'bring you back to Earth', and make you realize that you are not the center of the universe. Because of this point my circles often severely discourage certain individuals from partaking in the drug, especially females of a very narcissistic nature. We are not the types to directly refuse someone who comes to us seeking guidance, because we feel that if they are with us they will at least be safe, however we do inform some types of people that we are concerned that they are not ready to handle a specific drug or experience safely.

Supposedly the idea is it is dangerous to take a stereotypical selfish drama-centric college girl and let them use this drug without life counseling first, because having their attention rapidly brought to what a crappy person they are can cause severe emotional trauma. Basically coming to the realization that you're a bad person so fast that you don't have the time handle it and you have an emotional break.

Also, very strong warnings I should relay:

Never do this (or any hallucinogen) in public or crowded areas for your first time. The primary reason for 'bad trips' on things like this, especially salvia, is sensory overload.

In spirit communities these drugs are believed to help stimulate our other senses, our "supernatural" senses. When people try doing these drugs in high input areas their minds can't keep up with all of the processing. This overload can manifest in countless different ways depending mostly on the mood of the person. Sometimes the response is good, such as euphoria, other times the response is neutral, such as exhaustion and sleeping to attempt to limit further input and catch up. But the reason you have to be careful is that sometimes this overload can cause panic and anxiety, or in extreme cases even anger, confusion, and rage.

Go somewhere with very little input, don't watch TV*, listen to soft positive music, never have a group of more than a handful of people at the most, and make sure they are people you can absolutely trust. I personally always suggest Genesis or Phil Collins, because I enjoy it and I've always seen good results from that style of music. The music should be quiet, as should the company, everyone soft spoken, etc etc. Make sure to never play music that isn't quiet or have people being loud, because when you're unconscious you are often hyper sensitive to sounds. What would have been "loud" music while conscious could easily turn into deafening while on a trip. Incense and good smelling herbs are very strongly suggested. Comfortable area to lay down if necessary that doesn't require moving to get to, etc.

Two important points to expand on there: 1: TV is too much input, especially violent shows. I have personally been on a salvia divinorum trip while watching a TV show, and I ended up talking to the cast. Since it was a positive show the results were humorous, however friends have had instances watching drama shows where someone gets attacked and they freak out. 2: If someone messes with you while you are on any drugs, especially things like DMT or salvia, it can be extremely dangerous. Even childish crap like screaming "Boo!" can cause severe problems. If people are around there must be absolutely zero tolerance of any kind of behavior like that.

Some horror stories from my friends, either being people I know personally or a one step friend-of-a-friend. One person believed he was a giant banana being peeled by a gorilla. He started having a panic attack, was unable to breath, and was taken to the hospital. There is also a TV show that showed a boy [on salvia] getting up, running around the room, and then jumping out a window. That is a story that happened within one of my circles as well, with a slightly different middle part involving running into a table and a few walls.

This is why whenever someone asks about doing anything like this I strongly encourage they find a spirit guide, even if it is just someone to council them ahead of time and make sure they don't do any of the severe "no-no's" of any given ritual.

[Rewrote the post, still scatterbrained, but it is slightly better organized now. ]

Yes, I have had personal experience with this. Both through ingestion and inhalation.

It was a deeply profound experience, and ultimately changed my life. It acted as a catalyst for meditation and deeper inward searching. I did feel that I left my body, and I observed my time-space reality shrink down to a speck in the infinite. I sat in the infinite, and did observe another 'being' beckoning me up. It was a complete sense of oneness unlike any I've ever experienced, and what I can only describe as "soul-gasms" ran through my body for about 20 minutes. I was filled with vibrant energy, I felt a strong sense of vibration running through me.

Afterwards, I felt free from any fears of death. Are there any other details you would like to know?

3 BIG Mistakes

A DMT injection turns into a "hellish" experience

 "I had been up for three days and two nights working on a manuscript. That was the first mistake. The room where the "experiment" was to take place was a dirty, dingy, insanely cluttered pest hole. That was the second mistake. I was told that I would see God. That was the third and worst mistake of all.

  "The needle jabbed into my arm and the dimethyl-tryptamine oozed into my bloodstream. At the same time the steam came on with a rhythmic clamor and I remember thinking that it would be nice to have some heat. Within thirty seconds I noticed a change, or rather I noticed that there had never been any change, that I had been in this dreamy unworldly state for millions of years. I told this to Dr.--. who said, "Good, then it is beginning to cross the blood-brain barrier."

  "It was too fast. Much too fast. I looked up at what a minute ago had been doors and cabinets, and all I could see were parallel lines falling away into absurdities. Dimensions were outraged. The geometry of things crashed blindly into one another and crumbled into chaos. I thought to myself, "But he said that I would see God, that I would know the meaning of the universe." I closed my eyes. Perhaps God was there, behind my eyeballs.

  "Something was there, all right; Something, coming at me from a distant and empty horizon. At first it was a pinpoint, then it was a smudge, and then--a formless growing Shape. A sound accompanied its progress towards me--a rising, rhythmic, metallic whine; a staccato meeyow that was issuing from a diamond larynx. And then, there it loomed before me, a devastating horror, a cosmic diamond cat. It filled the sky, it filled all space. There was nowhere to go. It was all that was. There was no other place for me in this--Its universe. I felt leveled under the cruel glare of its crystalline brilliance. My mind, my body, my vestige of self-esteem perished in the hard glint of its diamond cells.

  "It moved in rhythmic spasms like some demonic toy; and always there was its voice--a steely, shrill monotony that put an end to hope. There should not be such a voice! It ravaged the nerves and passed its spasms into my head to echo insanely from one dark corridor of my mind to another. Me-e-e-e-yow~ow-ow-ow me~e~yow-ow-ow-ow me-e-e-e-yow-ow-ow-ow--the incessant, insatiable staccato went on. It would not have been so bad if it had just been diabolical noise. The chilling thing was that I knew what it was saying! It told me that I was a wretched, pulpy, flaccid thing; a squishy-squashy worm. I was a thing of soft entrails and slimy fluids and was abhorrent to the calcified God.

  "I opened my eyes and jumped up from my chair screaming: 'I will not have you! I will not have such a God! What is the antidote to this? Give me the antidote!' But as I said this I doubted my own question for it seemed to me that this was the only reality I had ever known, the one I was born with and the one I would die with. There was no future beyond this state of mind, there was no state of mind beyond this one.

  "'There is no antidote,' said Dr.--. 'Relax, it's only been three minutes. You've got at least twenty-five more minutes still to go.'

  "I looked around the room. The seething symmetry had calmed down some. Instead of evoking terror it merely made one seasick now. 'Euclidian nausea,' I thought, and closed my eyes again. I found myself on a small planet of a distant star. A spaceship built like an amoeba reached with long tentacles out to grab me. The center of the space ship was diaphanous like an embryo's head with a network of blue veins, flowing blood, and shifting cellular wastes. It pulsed and pulsed and whirred and cackled. I did not wish to be a part of this protoplasmic blob although it was far cheerier than the first vision, and so, as its tentacles were about to enclose me, I opened my eyes and escaped its interstellar plans for me. By this time I was learning how to manage--or should I say Escape from--the experience. I thought that I would start to call my own shots, find my own planet.

  "I closed my eyes again to discover a world of blue horses. The land heaved gently and the necks and heads of stately blue horses rose and fell as waves on the planet's surface. It was a land of perfect peace, a blue equine paradise.

  "But still I hadn't seen the face of God! I would make a final effort at ultimate visions. My eyes closed and I found myself looking through one end of an immensely long cylinder. At first, there was nothing at the other end--a trillion miles away. Then God came and peeked in at me. I burst out laughing.

  "The face of God staring at me from the other end of the cylinder was the face of a very wise monkey!"

  Concerning this case it may be superfluous to remark that the subject should not be told she is going to "see God" or discover "the meaning of the universe." Yet more than one researcher and therapist we know of has done this sort of thing repeatedly, and probably never with benefit to the subject or patient. Medical doctors no less than other kinds of workers with psychedelic drugs have promised visions of God, revelations of Ultimate Truth, and so on. And for the self-anointed psychedelic priest, it seems to be just a small further step to assuming the role of God Himself! Sidney Cohen and others have warned about this danger--the threat that an unaccustomed power will corrupt the guide with resulting damage to the subjects, and possibly even greater damage to the guide himself. This, as we also have observed, is a real danger; but psychiatrists have no immunity to the disease and they go astray when advancing such a hazard as a basis for restricting all work with psycho-chemicals to themselves. There exists not a shred of evidence to indicate that the limiting of guiding to one or a few professions will do anything at all to eliminate abuses of power and corruption by power.
