Even before the drug is administered, patients need to be in a soothing environment to maximize the efficacy of psychedelic agents—one that conveys complete safety, minimizes anxiety, and delivers preparatory therapy that sets expectations for the possibility of real benefit. Patients typically receive a moderate to large dose of psychedelic drug in each of two or three sessions spaced over several weeks. Psychedelics can induce a vulnerable state, not just during but also after use (Andersen et al., 2021). The incidence of HPPD appears to be much lower in the clinical context, perhaps as a result of efficient screening and preparation (Cohen, 1960; Johnson et al., 2008).

Renewed interest in the healing properties of such agents has led to the so-called “psychedelic renaissance,” in which many such substances are being studied how to taper off prozac 10mg for a wide range of conditions. Further research is required because the exact knowledge of what causes a challenging experience and who is susceptible to these experiences remains scarce. Importantly, there were no sex differences, and increased age and experience with the drugs was related to slightly less intense effects. Similarly, effects of LSD were not influenced by sex or body weight in a pooled study of 81 healthy subjects. However, genetic polymorphisms of the CYP2D6 enzyme – responsible for breaking down many commonly used medicines – significantly influenced the pharmacokinetics and in part also the subjective effects of LSD (Holze et al., 2021). In contrast, scientific research consistently assesses psychedelics as much less harmful to the user as well as to society compared to alcohol and almost all other controlled substances.

Ecstasy, or MDMA, is more difficult to categorize as a psychedelic because the hallucinogenic effects are less pronounced, and the mood-enhancing and stimulant effects are more noticeable than some other psychedelics. Lysergic acid diethylamide (LSD) is a chemically synthesized hallucinogen, developed from ergot, a kind of mold that grows on the rye grain. Also known simply as acid, LSD was widely used in the 1960s until it was made illegal.

1. Researchers are also investigating other drugs sometimes classified as psychedelic and dissociative drugs, such as MDMA, and the way they work in the brain.
2. However, the combination of MAOIs, such as that found in ayahuasca, with SSRIs has the potential to lead to serotonin syndrome (Gillman, 2010), highlighting the importance of educating ayahuasca drinkers of this potential risk.
3. PAP drug development currently involves plant medicines that have been used safely by indigenous populations for thousands of years, by western populations over successive generations and currently in clinical trials for many psychiatric disorders in controlled situations.
4. While psychedelic therapy shows promise in the treatment of a number of mental health conditions, it is important to recognize that this research is still in the early stages.
5. Subsequently, Health Canada granted exemption to 16 healthcare professionals to take psilocybin themselves for personal training (Dubinski, 2020), which is indicative of a rapidly growing infrastructure for psilocybin-assisted therapy in Canada.
6. However, genetic polymorphisms of the CYP2D6 enzyme – responsible for breaking down many commonly used medicines – significantly influenced the pharmacokinetics and in part also the subjective effects of LSD (Holze et al., 2021).

The quality of available evidence

Psilocybin is a psychedelic substance found in certain solution-focused therapy techniques fungi, sometimes referred to as magic mushrooms. There is a wide variety of hallucinogenic mushrooms, and their legal status is somewhat ambiguous, as they can be found growing wild in many parts of the world. Although peyote is a Schedule I drug, and is therefore illegal, the listing of peyote as a controlled substance does not apply to the use of peyote in religious ceremonies of the Native American Church. Dimethyltryptamine (DMT) is a naturally occurring plant-based psychedelic found in the bark and nuts of certain trees from Central and South America.

How do psychedelic and dissociative drugs affect pregnancy?

We have included evidence from both eras in an attempt to incorporate large evidence based on the safety of psychedelics. The approach of psychedelic-assisted psychotherapy (PAP) to psychiatric drug development is unique, a paradigm shift in fact. Therefore, this may not need to comply with the standard protocols required to enable a new chemical entity (NCE) to reach patients with a fully evaluated safety profile. Shahid et al. (2020) provide an extensive description of this process from drug target selection to testing in animal models, Phase I to Phase IV clinical studies to post-marketing surveillance and risk management.

In terms of LSD’s effects on humans, a 2018 study in Psychopharmacology found that people taking LSD in conjunction with having psychotherapy sessions reported increased feelings of happiness, trust, and empathy, resulting in positive social effects and altruism. An animal study published in Neuropsychopharmacologyin 2022 suggests that repeat doses of LSD over time can help to reduce stress-related anxiety and depression symptoms. Psychedelics are also known as hallucinogens because taking them can result in hallucinations. Hallucinations are sensory experiences that cause a person to see, hear, smell, taste, or feel things that are not really there. Someone who takes psychedelics may experience changes in their awareness of their thoughts and surroundings.

However, 200 out of the 641 participants taking part in Durante et al.’s (2020) study experienced tachycardia, and frequency of occurrence was higher in patients with a psychiatric diagnosis than those without. However, it is unclear if this was due to direct effects of ayahuasca or a result of participants’ underlying psychiatric disorder and/or medication. No difference in adverse effects was found between participants who used antidepressants and those who did not (31 participants reported using antidepressant medication). However, the combination of MAOIs, such as that found in ayahuasca, with SSRIs has the potential to lead to serotonin syndrome (Gillman, 2010), highlighting the importance of educating ayahuasca drinkers of this potential risk.

PAP drug development currently involves plant medicines that have been used safely by indigenous populations for thousands of years, by western populations over successive generations and currently in clinical trials for many psychiatric disorders in controlled situations. Such molecules do not require the same development steps as NCEs, as considerable information regarding their safety and efficacy already exists. Looking at the self-reported incidence of emergency medical treatment (EMT) sought for LSD and ‘magic mushrooms’, EMT is consistently low, and less than 1% of users report seeking help (Global Drug Survey (GDS), 2019). In comparison to other recreational drugs, psychedelics rank as the lowest in the United States, with 1.9 emergency department visits per 100,000 in 2011 (Substance Abuse and Mental Health Services Administration (SAMHSA), 2017). In relation to hospital admissions, SAMHSA (2017) shows that the rate of ‘hallucinogens’ as the primary substance is at 0.1% of hospital admissions.

However, researchers need to carry out more, and larger, well-designed clinical trials to help medical regulatory agencies decide whether to authorize psychedelics as medical treatments. And the ego dissolution effect of psychedelics enables people to see their thoughts and life from a less subjective, more objective standpoint. Ego dissolution may provide the link between psychedelic action and therapeutic effects in the brain. The effect of psychedelics on ego dissolution is similar to the effect achieved by long-time practitioners of meditation. The resurgence of interest can be attributed to the ability of the substances to induce lasting benefits with a remarkably short course of treatment—two or three doses.
