Ayahuasca dangers: mental and physical adverse effects

Ayahuasca ceremonies are usually held at night and last until the effects of Ayahuasca have worn off. After the space is prepared and blessed by the shaman leading the ceremony, Ayahuasca is offered to participants, sometimes split into several doses. When combined, these two plants form a powerful psychedelic brew that affects the central nervous system, leading to an altered state of consciousness that can include hallucinations, out-of-body experiences, and euphoria. If you’re living with a treatment-resistant mental health condition, it can be hard not to pin your hopes on a substance like Ayahuasca, which seems like it could be a quick fix. But instead of seeking out DMT or waiting for hallucinogenic therapies to become mainstream, Dr. Streem suggests learning about the clinically proven treatment options that already exist.

Although these reactions are transient and resolve themselves within a few hours, some people can suffer adverse effects. However, this risk is greater for those who have a history of psychotic episodes. You may have heard of DMT (dimethyl tetrahydrocannabinol), an alkaloid found naturally in many animals and plants. When used on its own, DMT produces a hallucinogenic experience with very differing effects from substances like psilocybin mushrooms or LSD.

Remarkably, even with eyes closed, levels of activation in the occipital area were consistent with the visionary experience20. Ayahuasca also activates the frontal cortex and areas involved in episodic memory. Furthermore, in one study using MRI, an inverse correlation between cortical thickness in the posterior cingulate cortex (PCC) and intensity and duration of previous ayahuasca use was observed13. This is highly relevant due to the direct implication of PCC in the default mode network (DMN), and it suggests that regular ayahuasca use could potentially lead to structural changes in certain brain areas. Jacob & Presti 190 suggested that DMT action at a trace amine receptor may produce an anxiolytic effect.

Another case involved a 27-year-old woman who had ingested 50 g of P. harmala seeds in a cup of coffee. She presented with hallucinations, bradycardia, nausea, and vomiting, but was discharged several hours later, and laboratory investigation results were all normal 109. In an attempt to investigate the toxicity of ayahuasca, Pic-Taylor et al. 112 administered ayahuasca doses 30 and 50 times higher than that typically used in religious rituals to female Wistar rats. While the authors could not calculate an LD50 based on their findings, they determined that the lethal dose is higher than 50 times a typical dose used in a religious setting. Pic-Taylor et al. 112 also found that the increased serotonergic activation from these high doses led to some neural degeneration, but no permanent alteration in brain structure or number of cells was found.

  • Still others suggest it may have neuroprotective and neurorestorative properties.
  • Moreover, in this study using a logistic regression analysis, a complex pattern of relationships between the study variables and the ayahuasca adverse effects is suggested.
  • Even so, some people say they grew to appreciate the taste over the course of their ayahuasca experiences.
  • There is not yet any scientific evidence—or even personal reports—indicating that ayahuasca use elicits substance dependence.
  • House et al. 103 noted that harmaline caused a dose-related suppression of CD8 activity, IL-2 and IL-4 production, B cell proliferation, and NK cell function.

One human trial showed that ayahuasca at 1 mg/kg, compared to 20 mg of dextroamphetamine, did not affect subjective sleep quality, initiation or maintenance as measured by polysomnography, decreased REM, and increased slow-wave sleep power 76. A further experiment showed that low doses (0.25 and 0.5 mg/kg) augmented startle response while a high dose (4.0 mg/kg) depressed it 79. A 2002 study assessing sensory and sensorimotor gating showed that with increasing ayahuasca doses there were dose-dependent reductions in P50 suppression 44, 65. P50 suppression is a test of sensory gating in which paired clicks are heard 50 milliseconds apart, and normally with the second click the amplitude of brain waves (auditory evoked potentials) is much lower, as the brain perceives it as redundant. As an example, in people with schizophrenia, the amplitude is reduced much less than in people without schizophrenia, indicating difficulty with sensory gating.

The Role of Shamans in Ayahuasca Healing

Kuypers et al. 57 looked at ayahuasca’s effect on creative divergent thinking, a way of thinking believed to enhance psychological flexibility and allow for new cognitive, emotional, and behavioural strategies. Assessing participants before and during the acute effects of ayahuasca, the authors found significantly increased divergent thinking while the subjects were on ayahuasca, and suggested this may facilitate psychotherapeutic interventions. Other studies indicate that creativity and creative thinking are also influenced by ayahuasca. Kuypers et al. 26 evaluated the effects of ayahuasca on creative thinking by performing creativity tests before and during the effect of ayahuasca in 26 participants of spiritual workshops.

Foods containing tyramine, such as aged cheeses or fermented products, can interact with MAO inhibitors, potentially leading to hypertensive reactions. Additionally, individuals taking medications that affect serotonin levels, such as SSRIs, face heightened risks of serotonin syndrome. The other measure where experienced users scored higher than naïve users was self-transcendence (ST). There are multiple studies that have shown that psychedelics can induce long-term personality changes45.

Ayahuasca does not show activation in reward-related regions of the striatum or ventral-tegmental area on SPECT imaging 51,70, and only causes increased blood flow in the frontal and paralimbic areas. The main mechanisms of action proposed for beta-carbolines include the MAO-A inhibitory activity, dopamine efflux, and affinity for the 5-HT2A binding site 140. Harmine has also been found to regulate expression of the peroxisome proliferator-activated receptor gamma (PPAR-ɣ, also known as the glitazone receptor) and shows some antitrypanosomal activity 144.

4. Pain Treatment and Opioid Dependence

  • The hallucinogenic effects are only possible through the combination of these two plants.
  • However, a tendency was observed in scores obtained by most of the questionnaires, as they decreased significantly (data not shown).
  • In total, 11 participants reported they had no experience with ayahuasca (40.7%).
  • Search ethnobotanical suppliers and reputable headshop websites to purchase ayahuasca plant materials.

While both ayahuasca and magic mushrooms have hallucinogenic properties, there are differences between the two substances. Supporting this idea, further evidence also suggests that there are beneficial effects of ayahuasca for those with tobacco and alcohol dependence. After 6 months, the participants continued to report positive and lasting changes. They also showed improvements in their overall quality-of-life scores, mindfulness, and sense of empowerment and hope. Ayahuasca may also help treat anxiety and mood disorders, according to a review of six studies. Neuroimaging tests report that ayahuasca increases blood flow to areas of the brain that help regulate emotions and memory, including the medial temporal lobe, amygdala, and hippocampus.

Group 1: the Dutch sample

These dysfunctional behaviors were virtually resolved after joining the UDV and attending regular ceremonies. The first effects reported by the volunteers were physical changes, including burning sensations in the stomach, tingling sensations, changes in perception of body temperature and skin sensitivity, and mild nausea. Hallucinations reminiscent of ayahuasca art were typically intense and experienced suddenly. Most reported a degree of initial anxiety or fear, which faded in all but one case thereafter. Caapi vine is stripped of its bark, pounded, or shredded to increase surface area for alkaloid extraction. Both components are then combined in a vessel with water and subjected to slow, sustained effects of ayahuasca heating over several hours.

Healing Chronic Pain

Members of the American ayahuasca churches kept their use quiet until 1999 when the United States‘ Drug Enforcement Administration (DEA) confiscated ayahuasca that had been smuggled in. The UDV began a federal lawsuit in 2000 32, where under the Religious Freedom Restoration Act of 1993, they argued they could use ayahuasca on the basis of religious freedom, and the courts agreed 1. The federal government appealed the decision several times until, in 2006, the US Supreme Court unanimously decided to allow the ceremonial use of ayahuasca in the UDV church, as they were unable to demonstrate that it had any detrimental effects 3, 33. The Santo Daime religion fought a similar battle in Oregon, likely benefitting from the precedent set by the UDV church, and won an injunction allowing ceremonial use of ayahuasca in 2009. Even before that, the Oregon State Board of Pharmacy concluded in 2000 that in the Santo Daime religion, ayahuasca had a “nondrug” use, and was not subject to state regulation 1. A topic of heated debate, the Brazilian government decided in 2010 that for pregnant women and children to consume ayahuasca is an “exercise of parental rights” 12.

For some, those side effects were significant enough to require the help of a mental health professional. Of the more than 10,000 people who completed the Global Ayahuasca Survey, about 70% of the participants experienced physical side effects while using the substance, with nausea and vomiting being the most common (and, frankly, expected) symptom. Here is what everyone should know about the effects of ayahuasca, as well as important considerations when determining whether or not it’s right for you.

After a particularly harrowing trip that included grand mal seizures and hyper-anxiety inducing hallucinations, Ferriss claims that “ninety percent of the anger I had held onto for decades, since I was a kid, was just gone. Absent.” 20 He also claims that almost everyone of any influence in the startup industry uses ayahuasca at some point. Learn more about what to expect in an ayahuasca experience in this video by Paul F. Austin.

On average, similar increments in mindfulness were obtained at 4 weeks after the ayahuasca ceremony, but this time, these no longer achieved statistical significance. It should be noted that ayahuasca-induced changes in mindfulness were much smaller than changes in symptoms of depression and stress. It is concluded that ayahuasca produces sub-acute and long-term improvements in affect and cognitive thinking style in non-pathological users. Only 2.3% of participants reported physical adverse events required medical attention for this issue. Among all participants, 55% also reported adverse mental health effects, including hearing or seeing things (28.5%), feeling disconnected or alone (21.0%), and having nightmares or disturbing thoughts (19.2%).

Since DMT is known to be a very potent 5-HT agonist, it can decrease impulsive behavior and facilitate social interactions (Frecska, 2008). A rapid 5-HT receptor action can explain the traditional indication of ayahuasca use in crisis prevention and occasioning redemption (de Rios et al., 2002). The prosocial, cohesive action effect of ayahuasca is reflected in the quality of the elicited subjective experience, which commonly involves ethical lessons (Shanon, 2002). Ayahuasca is highly revered by mestizo curanderos as a stern moral teacher (Luna, 1986).
