What Is Ayahuasca? Experience, Benefits, and Side Effects
Morgenstern et al. [81] reported that almost no hallucinogen users had difficulty cutting down or controlling use, unlike many other drugs. In a study of rhesus monkeys, Fantegrossi et al. [82] found reinforcing effects of the hallucinogens DMT, mescaline, and psilocybin, and suggest that the patterns of self-administration demonstrate weak reinforcing effects, and possibly mixed reinforcing and aversive effects. Ayahuasca does not seem to have the negative psychosocial implications caused by many drugs of abuse [51]. Mixed results were found in studies of drug tolerance in animal studies [83-85] as well as in human studies [3], particularly to the psychoactive effects, which is unique among other known hallucinogens. Callaway et al. [86] found that some physical tolerance may develop in humans with regular use.
Treatment for the Long-Term Side Effects of Ayahuasca
Areas involved in episodic memory were also activated, including the parahippocampal gyrus (BA 30) and the middle temporal cortex (BA 37). Emotions and memories were intensified and past experiences were seen through vivid imagery, which gave the whole experience a “status of reality” [71]. The posterior cingulate cortex (PCC) is key component of the default mode network, a group of neural pathways involved in inwardly focussed thought, conception and awareness of self, remembering the past and envisioning the future.
Participants
Our sample was not clinical, but 45% of subjects met the criteria for a psychiatric disorder. The same pattern of improvement was observed in the role-emotional scale from the SF-36. A similar study with a sample similar to ours also found long-term improvements in the role-emotional and social function scales from the SF-36 questionnaire25. This finding is in line with previous research in which ayahuasca showed antidepressant effects at 7 and 21 days after its controlled administration in a clinical setting14,15,16.
4. Brain Structures Involved in the Ayahuasca Experience
Those users could be resistant to some of ayahuasca’s adverse effects, allowing them to use it without perceiving any harm, and thus they tend to participate as volunteers in the studies. However, by analyzing the experience of first-time users, this bias may be better controlled for and more accurate information about the overall effects of ayahuasca on novice users can be obtained. Ayahuasca’s safety has been demonstrated in clinical trials involving both different dosages and multiple administrations [13, 14, 35–45], as well as in naturalistic settings [21, 24–30].
Electrophysiologic studies and imaging
In case of DMT, a recent study (Carbonaro et al., 2015) concluded that while 5-HT2A receptors play a major role in mediating its effects, mGluR2 receptors likely modulate the action. Unlike the related tryptamine derivative psilocybin, DMT does not precipitate tolerance upon repeated use (Strassman et al., 1996); this produces further complications for simple receptor-based interpretations. When someone takes DMT orally, it doesn’t become activated as a hallucinogenic without the inclusion of another substance that acts to stop the metabolism of the substance. The DMT can be combined with various other substances to enhance the psychedelic effects and prevent DMT from being metabolized before it crosses the blood-brain barrier. DMT stands for dimethyltryptamine, and it’s a hallucinogenic substance that is naturally present in plants and animals. It’s been used for thousands of years in South American ceremonies and religious events, and it can be produced synthetically as well.
- Ayahuasca also produced significant sub-acute improvements in subjective ratings of mindfulness and satisfaction with life.
- We view substance misuse as a unhealthy coping mechanism or self-medication for emotional distress.
- The average ceremonial dose of DMT in ayahuasca preparations is about 27 mg; therefore, the safety margin for ayahuasca is approximately 20 (Gable, 2007).
- Schenberg et al. [64] showed a biphasic effect of ayahuasca on EEG, with reduced power in the alpha band (8-13 Hz) found 50 minutes after ingestion, and this effect was mainly found at the left parieto-occipital cortex.
- Another theory proposed that DMT may even serve to suppress psychotic activity, acting as a homeostatic agent [27].
Breaking the Stigma: Promoting Awareness of Perinatal Mental Health
Researchers at the University of Melbourne used data for a study on ayahuasca dangers from an online global survey carried out between 2017 and 2019, involving 10,836 people from more than 50 countries who were at least 18 years old and had used ayahuasca at least once. DMT could have serious adverse consequences for users with pre-existing psychological problems or a mental illness, such as schizophrenia. If someone does not address serotonin syndrome, it can cause life threatening complications, including seizures, kidney or respiratory failure, or loss of muscle tissue.
Central Nervous System Effects of Ayahuasca
Reported benefits included self-knowledge, improved interpersonal relations, and gaining new perspectives on life. Participants scored significantly above average on the Personality Style and Disorder Inventory (PSSI, Persönlichkeits-Stil- und Störungs-Inventar) scales of “intuition, optimism, ambition, charm, and helpfulness and significantly lower on the scales of distrust and quietness”. While most experiences of this variety with ayahuasca are relatively safe, Arrevalo [22] warns against inexperienced or false shamans using toxic plants as additives to the ayahuasca preparation.
Exposure to the ayahuasca ceremony also increased convergent thinking as assessed with the picture concept task. The number of correctly detected associations increased with 9% sub-acutely and with 29% at the 4-week follow-up. At the latter time point, the increase in cognitive performance also reached statistical significance. The PCT task has previously been used in an observational ayahuasca study to show that the brew increases performance at the divergent, creative thinking assignment but decreases performance in convergent thinking assignments (Kuypers et al. 2016).
Self-rated satisfaction with life (SWL) increased during the sub-acute and long-term assessment when compared to baseline. During the sub-acute and follow-up assessments, participants’ scores increased up to average (range 20–24) and marginally high (range 25–29) levels of SWL, respectively. Although people with average and high SWL are generally satisfied with their lives, the individuals with average scores desire greater improvements in one or several life’s domains (Pavot et al., 1991).
Other common physical side effects reported include changes in body perception and alterations like an electric/tingling feeling, change in body temperature, and dizziness, among others. All adverse physical effects are temporary and are not considered severe [47, 48]. The researchers also identified several factors that predispose people to the adverse physical events of the drug, including older age, having a physical health condition or substance use disorder, lifetime ayahuasca use and taking ayahuasca in a non-supervised context. Similarly, results of psychometric tests applied by dos Santos’ group (dos Santos et al., 2007) revealed that after ayahuasca use, individuals respond with less anxiety to states that involve hopelessness and resemble panic, while measures of state- or trait-anxiety remain unaffected.
A subgroup analysis involving only those subjects who met psychiatric diagnostic criteria was conducted. Several ayahuasca ceremony leaders from different parts of Spain were contacted and asked to inform us when ayahuasca-naïve subjects called them to participate in their ayahuasca ceremonies. In this way we recruited 40 ayahuasca-naïve subjects (28 antidepressants and alcohol interactions women) for sub-study 1. Regarding sub-study 1, 40 ayahuasca-naïve subjects were assessed before using ayahuasca for the first time, and they were followed up with at 1 and 6 months after. Following the usual pattern of participants in complementary and alternative medicines30, the majority of the sample consisted of women with higher education.
The present study aimed to assess sub-acute and long-term effects of ayahuasca on well-being and cognitive thinking style. The second objective was to assess whether sub-acute and long-term effects of ayahuasca depend on the degree of ego dissolution that was experienced after consumption of ayahuasca. Overall, adverse health effects were reported by nearly 70% of participants with the most common effects being vomiting and nausea, headache, and abdominal pain. About 2% of participants who reported adverse physical events required medical attention.
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 how psychedelic drugs can be used for mental health the new york times 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].
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. Traditionally, a shaman or curandero — an experienced healer who leads Ayahuasca ceremonies — prepares the brew by boiling torn leaves of the Psychotria viridis shrub and stalks of the Banisteriopsis alcohol use abuse and depression caapi vine in water. “With the emergence of telehealth, cutting-edge counseling techniques are more accessible than they’ve ever been before,” he says. Dr. Streem says people who use Ayahuasca for non-spiritual purposes usually do so because they want to experience side effects they perceive as positive, like euphoria. The Satisfaction with Life Scale (SWLS) is a 5-item self-report scale (Diener et al. 1985).
