The main effect of DMT is psychological, with intense visual and auditory hallucinations, euphoria, and an altered sense of space, body, and time. When smoked, DMT produces brief yet intense visual and auditory hallucinations that have been described by users as an alternate reality, otherworldly, or a near-death experience. In comparison to other psychedelic drugs, such as LSD, ketamine, and magic mushrooms, recreational users of DMT consider it to have the lowest side effect profile.
When taken orally, DMT can cause nausea, vomiting, and diarrhea. Depending on the individual user, the DMT experience can range from intensely exciting to overwhelmingly frightening. DMT is structurally related to the neurotransmitter serotonin and, because of this, a condition called serotonin syndrome is a potentially lethal health risk associated with its use. Individuals taking antidepressants are at highest risk for this complication.
Serotonin syndrome occurs when the body accumulates an excessive amount of serotonin. The condition is often caused by taking a combination of different drugs. DMT could have serious adverse consequences for users with pre-existing psychological problems or a mental illness, such as schizophrenia. Due to limited research data, DMT is not known to cause physical dependence or addiction , although frequent recreational users may develop psychological cravings for the drug.
Although it is not considered an addictive substance, DMT has several health risks, can produce terrifying hallucinations, and might lead to psychological dependency.
LSD, made from lysergic acid, is a potent, mood-changing chemical. The primary effect of LSD is to alter the senses and cause hallucinations. Tactile hallucinations involve sensations that are not explained by outside physical factors, such as that bugs are crawling over the body, or that…. Scientists have made a discovery that explains why 'acid trips' last for so long when LSD molecules are cleared from the bloodstream in a couple of….
Antidepressants improve mood by boosting serotonin levels, but serotonin can have negative effects, too. Similar to other psychedelics, history of mental health illness such as schizophrenia, psychosis and bipolar disorder may increase the likelihood of an unpleasant experience and there is the risk DMT may exacerbate these conditions.
However, there is still a limited understanding of the risks associated with the use of psychedelics in those with pre-existing mental health conditions. This can result in a potentially life-threatening condition called serotonin syndrome. This includes some antidepressants and selective serotonin reuptake inhibitors SSRIs.
DMT should not be mixed with alcohol or other drugs and an understanding of the effects and mechanism can provide insight into the risks associated with mixing it with other drugs. Key drug combinations to avoid are listed below:. DMT, along with other classical psychedelics, is not addictive. However, tolerance can develop with frequent use, whereby a higher dose is required to achieve the same effect. DMT is a powerful psychedelic drug that can produce a rapid and intense hallucinogenic experience.
Informed harm reduction advice can help to mitigate some of the associated risks. It is important that you fully educate yourself on the health risks and drug interactions associated with DMT. It is important to ensure that the correct form and method of consumption is used, as well as a suitable dose.
The particularly intense nature of DMT makes it important that sufficient preparation is done. This includes an awareness of the psychological and physical effects that DMT may induce. This can have a significant effect on the experience of the trip and therefore it is advised that DMT is only consumed when a person is in a positive and stable state of mind. DMT should be consumed in a safe and calm environment, due to the intensity of the trip and the potential motor impairments.
The presence of a sober sitter is particularly recommended with DMT. The sitter can provide reassurance and support during and after the trip. The sobriety of the sitter is essential and can provide a sense of clarity and guidance through any disorientating or overwhelming experiences. There has been extensive debate as to whether DMT is produced in the human brain.
A lot of the debate has been focused around the pineal gland, a tiny organ in the centre of the brain, which had been popularised by many as the primary producer of DMT. However, currently scientific evidence to support this theory remains very limited. Trace amounts have been detected in human blood and urine , supporting the idea of the endogenous production of DMT in the human body.
Although a recent study detected DMT in the pineal gland of rats, there has been no evidence of this in the pineal gland of the human brain. A subsequent study demonstrated that DMT is still produced in the rat brain after removal of the pineal gland, adding further fire to the debate as to whether the pineal gland is the primary source of DMT.
Understanding endogenous DMT production in the human body and its potential roles in physiology remains an understudied area and extensive further studies are needed.
While they may look similar, and have similar chemical structures, they induce different experiences and should not be confused. Psilocybin Magic Mushrooms.

Chris Timmermann, a psychologist and neuroscientist who researches psychedelic drugs, stands nearby. The hallucinations hit her like a hurricane. A sense of dread envelops her. As expected, Iona didn't suddenly dematerialise into a swirling space-time void.
This intense journey took place entirely within her own mind — induced by an illegal drug that sits on the periphery of recreational psychedelics. DMT is perhaps best known as the hallucinogenic compound in ayahuasca. This bitter, brown liquid is created by combining two plants — the ayahuasca vine and a shrub called chacruna — and has been used ritually and medicinally by Amazonian tribes for centuries.
The mysterious allure of the ayahuasca ritual seems to hold a particular appeal for young Westerners, who have helped spawn a cottage industry of ayahuasca tourism in South America. Those who seek it out may believe it can heal , provide a glimpse of death, or perhaps even the afterlife. But it is not a drug without risks. Ayahuasca could trigger issues in those who are predisposed to mental health problems and four years ago, a year-old British backpacker died following an ayahuasca ceremony.
Human trials involving illegal drugs demand a strict ethical and regulatory framework and the express permission of the Home Office. Imperial College's Psychedelic Research Group has consistently met the requirements for such trials.
They are recording the effects of the drug in new ways, thanks to advancements in brain mapping technologies such as functional magnetic resonance imaging fMRI. Iona describes some of this "disorder" as feeling detached from her body and says she quickly found she was experiencing a strange, unfamiliar detachment from her sense of self too. It just seemed like everything was rotating and swirling and spiralling.
Iona struggles to put into words exactly what she experienced. But towards the end of the test, she remembers an overwhelming feeling of gratitude that she had survived and a strange sense of reassurance. Ego death is like being awake and having no sense of personal identity. The dose of DMT used in the study is a tiny fraction of the toxic dose — so participants were not on the verge of death, even when they felt they were.
