Hallucinogens can also affect regions of the brain that deal with regulating arousal and physiological responses to stress and panic, according to the National Institute on Drug Abuse NIDA research.
For more mental health resources, see our National Helpline Database. People who use hallucinogens can see things, hear things and feel sensations that seem to be very real, but do not in fact exist. These altered perceptions are known as hallucinations.
Typically, these hallucinatory effects can begin from 20 to 90 minutes after ingestion and can last up to 12 hours. One problem for users of hallucinogens is the fact that the effects of the drug can be highly unpredictable. The amount ingested, plus the user's personality, mood, surroundings, and expectations can all play a role in how the "trip" will go. What hallucinogens can do is distort the user's capacity to recognize reality, think rationally and communicate.
In short, a drug-induced psychosis, and an unpredictable one. Sometimes, the user will experience an enjoyable and mentally stimulating trip. Some report having a sense of heightened understanding.
But, users can have a "bad trip," that produces terrifying thoughts and feelings of anxiety and despair. According to NIDA research, bad trips can result in fears of losing control, insanity, or death. The following is a list of short-term effects of hallucinogenic drugs, provided by the NIDA:.
Psilocybin is a naturally occurring hallucinogen found in some types of mushrooms. It can cause:. While the effects can vary depending on the type of hallucinogen and dosage, there are some general short-term effects that most of these drugs share.
One result of the repeated use of hallucinogens is the development of tolerance. Studies show that LSD users develop a high degree of tolerance for the drug very quickly. They invariably induce a series of visual hallucinations, often in kaleidoscopic movement, and usually in indescribably brilliant and rich colours, frequently accompanied by auditory and other hallucinations" - tactile, olfactory, and temporal.
Indeed the effects are so unearthly, so unreal that most hallucinogenic plants early acquired a sacred place in indigenous cultures. In rare cases, they were worshipped as gods incarnate. The pharmacological activity of the hallucinogens is due to a relatively small number of types of chemical compounds.
While modern chemistry has been able in most cases successfully to duplicate these substances, or even manipulate their chemical structures to create novel synthetic forms, virtually all hallucinogens have their origins in plants. One immediate exception that comes to mind is the New World toad, Bufo marinus, but the evidence that this animal was used for its psychoactive properties is far from complete. Within the plant kingdom the hallucinogens occur only among the evolutionarily advanced flowering plants and in one division - the fungi - of the more primitive spore bearers.
Most hallucinogens are alkaloids, a family of perhaps 5, complex organic molecules that also account for the biological activity of most toxic and medicinal plants. Hallucinogens may be smoked or snuffed, swallowed fresh or dried, drunk in decoctions and infusions, absorbed directly through the skin, placed in wounds or administered as enemas. To date about hallucinogenic plants have been identified worldwide.
On first glance, given that estimates of the total number of plant species range as high as ,, this appears to be a relatively small number. However, it grows in significance when compared to the total number of species used as food. Perhaps 3, species of plants have been regularly consumed by some people at some period of history, but today only remain important enough to enter world commerce. Of these a mere , mostly domesticated cereals, keep us alive. In exploring his ambient vegetation for hallucinogenic plants, man has shown extraordinary ingenuity, and in experimenting with them all the signs of pharmacological genius.
He has also quite evidently taken great personal risks. Peyote Lophophora williamsii , for example, has as many as 30 active constituents, mostly alkaloids, and is exceedingly bitter, not unlike most deadly poisonous plants.
Yet the Huichol, Tarahumara and numerous other peoples of Mexico and the American Southwest discovered that sundried and eaten whole the cactus produces spectacular psychoactive effects.
With similar tenacity, the Mazatec of Oaxaca discovered amongst a mushroom flora that contained many deadly species as many as 10 that were hallucinogenic. These they believed had ridden to earth upon thunderbolts, and were reverently gathered at the time of the new moon.
Elsewhere in Oaxaca, the seeds of the morning glory Rivea corymbosa were crushed and prepared as a decoction known at one time as ololiuqui - the sacred preparation of the Aztec, and one that we now realize contained alkaloids closely related to LSD, a potent synthetic hallucinogen.
In Peru, the bitter mescaline-rich cactul Trichocereus pachanoi became the basis of the San Pedro curative cults of the northern Andes.
Here the preferred form of administration is the decoction, a tea served up at the long nocturnal ceremonies during which time the patients' problems were diagnosed. At dawn they would be sent on the long pilgrimages high into the mountains to bathe in the healing waters of a number of sacred lakes. Lowland South America has provided several exceedingly important and chemically fascinating hallucinogenic preparations, notably the intoxicating yopo Anadenanthera peregrina and ebene Virola calophylla, V.
Yopo is prepared from the seeds of a tall forest tree which are roasted gently and then ground into a fine powder, which is then mixed with some alkaline substance, often the ashes of certain leaves. Ebene is prepared from the blood red resin of certain trees in the nutmeg family. Preparations vary but frequently the bark is stripped from the tree and slowly heated to allow the resin to collect in a small earthenware pot where it is boiled down into a thick paste, which in turn is sundried and powdered along with the leaves of other plants.
Ayahuasca comes from the rasped bark of a forest liana which is carefully heated in water, again with a number of admixture plants, until a thick decoction is obtained. All three products are violently hallucinogenic and it is of some significance that they all contain a number of subsidiary plants that, in ways not yet fully understood, intensify or lengthen the psychoactive effects of the principal ingredients.
This is an important feature of many folk preparations and it is due in part to the fact that different chemical compounds in relatively small concentrations may effectively potentiate each other, producing powerful synergistic effects - a biochemical version of the whole being greater than the sum of its parts. The awareness of these properties is evidence of the impressive chemical and botanical knowledge of the traditional peoples.
In the Old World may be found some of the most novel means of administering hallucinogens. In southern Africa, the Bushmen of Dobe, Botswana absorb the active constituents of the plant kwashi Puncratium trianthum by incising the scalp and rubbing the juice of the onion-like bulb into the open wound.
My ego is one of a couple of characters in my mind, and not always the best. The ego is very important — the ego got the book written. Apparently you can milk the toad repeatedly and kind of squeeze the glands on its side or its arm onto a sheet of glass. It dries overnight and looks like brown sugar crystals. I had not only the experience of ego-dissolution, but the dissolution of everything: of my body, of any kind of perceiving consciousness, of material reality.
It was all gone. I felt like I was in the middle of an atomic blast or in a world before the Big Bang, when there was only energy and not yet matter. The best thing about this trip is it only lasted about 15 minutes. And then I could feel my body. I was like, wow! I kind of feel like I went back to baseline. I think she may well be right. Simply spending this much time observing my mind and having experiences where I got to sneak up on it in various ways does have an effect.
We often think about science and spirituality as these opposed terms, but in fact a lot of this research is forcing scientists to deal with spiritual questions, and some spiritual people to deal with scientific questions, which is very exciting. The very first study in the modern era of psychedelic research, of any importance, was a study done at Johns Hopkins by a scientist named Roland Griffiths, a very prominent drug-abuse scientist. It has various aspects to it.
Prominent among them is this dissolving of a sense of self, but that is followed by a merging with the universe, or with nature, or other people. We see this experience all over religious literature: people who have had an experience of meeting with the divine.
These traits are common, and the fact that you could induce such a spiritual experience with a single administration of a drug was quite remarkable. These people reported that this experience was one of the top two or three in their lives, comparable to the birth of a child or the death of a parent.
Now that we can actually induce a spiritual experience using a drug, we can study the phenomenon. It made me more curious and a little less afraid. On this psilocybin trip, I saw the faces of people close to me who had died over the last few years. You understand why traditional cultures would take plant medicines to reconnect with the dead. You can see them and talk to them and they can talk to you. I wrote this book during a period when my dad was dying.
He had terminal cancer, and I dedicated this book to him before he died.
