Of note, previously it was demonstrated by Isbell and colleagues that tolerance to the effects of (a higher dose of) LSD (75 mcg) occurred after repeated dosing with low doses of LSD (10–30 mcg), given twice daily for 3 days in a row.41 Nonetheless, this tolerance was transient and disappeared after three dose-less days. Based on this information, it is tentatively concluded that daily dosing, something that is not common practice amongst users, will probably be not efficacious, while 2–3 days in between would already be sufficient to curb the tolerance. Preliminary findings with full psychedelic doses demonstrated remission from depression after one or two doses,63 with the quality of the psychedelic experience being predictive in the therapeutic outcome.12 Future research can test the efficacy of low versus higher doses of psychedelics in the treatment of depression, and the longevity of therapeutic effects and its predictors. Interestingly, in this light was the tolerance to perceptual effects of a higher dose of LSD after three repeated low doses LSD administered on consecutive days,43 which suggests adaptation at receptor level. Although subject to limitations inherent in cross-sectional surveys and with a recognition that the benefits and harms of psychedelic use in a naturalistic environment are likely to be different than those seen in clinical trials, the Psychedelics and Wellness Study (PAWS) was designed are psychedelics addictive to address these and other gaps in the psychedelic literature. In particular we sought to test the hypothesis that a robust interrelationship would be observed between past psychedelic use and current levels of emotional wellness (assessed as well-being and depressive and anxious symptoms).
- Previous research has shown that psychedelics are at their most beneficial when coupled with therapy.

- We sought to examine associations between frequency of psychedelic use and wellness-related outcomes, as well as the prevalence and types of harms engendered by past use.
- Given the widespread emerging use of ketamine as a “psychedelic-like” agent for the treatment of major depressive disorder, we included this agent in our survey, although we recognize that it is not a classic psychedelic.

An older study already showed that participants who were trained to recognise the effects of psychedelics were able to do this.58 This potentially lowered detection threshold in experienced users would imply they need less of the substance or conversely, drug naïve (patients) would need a higher microdose to experience equal effects. Results from the current study suggest several potentially fruitful lines of future research. Survey-based studies of naturalistic psychedelic use might use Sobriety prospective designs to more rigorously confirm, or disconfirm, our findings regarding associations between increased frequency of psychedelic use in naturalistic environments and enhanced self-reported wellness. Our results also highlight the importance of looking more exhaustively at the types of harms that naturalistic psychedelic use may engender, as well as their risk factors and impact on long-term well-being and social functioning.
Association of Lifetime Psychedelic Use With Depression, Anxiety and Emotional Well-Being
These produce plasma-concentration related psychological effects such as hallucinations and out of body experiences, insightful and emotional breakthroughs as well as mystical-type experiences. When coupled with psychological support, effects can produce a rapid improvement in mood among people with depression that can last for months. In this chapter, we summarise the scientific studies to date that explore the use of psychedelics in depressed individuals, highlighting key clinical, psychological and neuroimaging features of psychedelics that may account for their therapeutic effects. These include alterations in brain entropy that disrupt fixed negative ruminations, a period of post-treatment increased cognitive flexibility, and changes in self-referential psychological processes.
Data Availability Statement
Dr. Scott Thompson is a neuroscientist at the University of Colorado School of Medicine. He’s studied psilocybin and is currently part of the research team led by Dr. Andrew Novick., an MD in the Department of Psychiatry at CU Anschutz, looking into how psilocybin-assisted therapy could help people with treatment-resistant depression. Methodological details of the included experimental studies with low doses of LSD.
Classical psychedelics for the treatment of depression and anxiety: A systematic review
Thompson says the next step is to verify if the same results are produced in the human clinical trials. The concern with mixing SSRIs and psychedelics is not about negative results, but potentially reduced affectiveness. Depression, anxiety, and well-being scores for pre- and post-psychedelic usage. Illegal and long stigmatized as drugs of abuse, psychedelics seem unlikely candidates for the explosion of cultural interest and commercial development they have engendered in recent years.
Study in patients with anxiety
Greiner et al. conducted a dose-effect study with five different doses of LSD and placebo administered to 14 healthy male volunteers. While they mentioned it was a double-blind design, they did not describe how many doses participants received, which was more than one as they stated that three participants received placebo, two 4 mcg, six 7 mcg, two 12 mcg, six 20 mcg and five 40 mcg LSD. Effects on self-rated mood and perception (of e.g. thoughts, body image), physiological measures, and observed mood and psychomotor behaviour were measured at least up to 4 h after treatment. In addition, future studies might also want to compare the effects of a range of low doses between groups of people who have experience with the use of psychedelics, and those who are drug-naive, as previous experience might increase the sensitivity to detect changes in for example, mood state.

- Psychedelic drugs such as psilocybin and ketamine are returning to clinical research and intervention across several disorders including the treatment of depression.
- If confirmed in subsequent populations, this will highlight the importance of using psychedelics as spurs to initiate changes in lifestyle/perspective that are mental health protective, rather than attempting to use these agents as lifelong mood modifiers.
- In particular, our finding that a minority of participants felt that psychedelic use had increased the problematic use of other substances is an area of obvious importance for the development of these agents as novel therapeutic modalities.
The mice also showed improvements in a behavior test thought to be relevant to depression. Here’s more information about the study on depression, including criteria for people interested in participating. Healing centers and facilitators will be required to ask patients about family and medical history before proceeding with psychedelic-assisted therapy. There is still a lot to be learned about the biology of psychedelics, particularly long-term effects. Thompson also differentiates between negative experiences and challenging experiences.
Study in obsessive compulsive disorder patients
Some of those studies included low doses of LSD and are described in detail here.36,40–42 Next to that, five recent studies were identified and included here; these aimed to assess the effects of a microdose LSD on cognition, subjective perception and brain activity.27,33,37–39 Given that the methodology of older studies did not always meet current standards, more methodological detail is provided for these studies, so that findings are interpreted in that specific context. It’s currently believed that these psychedelic experiences could be necessary for potential therapeutic benefits, but more research needs to be done. Table 1 presents demographic information on the 2,510 adults who completed the study survey. Participants ranged in age from 18 to 86, with an equal representation of males and females. The study sample averaged 38.55 (range 1-500) lifetime uses of a psychedelic, with most participants identifying psilocybin or LSD as their preferred psychedelic (psilocybin 51.6%; LSD 30.1%).
Controlled, experimental studies
These findings, while preliminary, have generated such excitement in part because their implications stand in sharp contrast to results from a series of landmark studies conducted over the last 20 years that have increasingly eroded confidence in the effectiveness of standard psychopharmacological agents, especially widely used antidepressant medications (16). The current passion for psychedelics may also be driven by a widespread perception that psychedelic treatment by its very nature will demand a longed for, but previously unattainable, integration of pharmacology and psychotherapy (17), as well as by the fact that many people have used psychedelics in naturalistic settings and therefore have firsthand experience of their potential psychological impact. Effect of psychedelic exposure in participants with and without reported harms for use. (A) Effect of harms on depressive symptoms measured with the 9-items Patient Health Questionnaire (PHQ-9). (B) Effect of harms on anxious symptoms measured with the 7-item Generalized Anxiety Scale (GAD-7).
However, in this CU study, Thompson, Dr. Novick and their colleagues have minimized the amount of therapy involved in order to study the effects of psilocybin doses on the trial participants, which focuses on a symptom of depression called anhedonia. The PAWS survey anonymously collected participant, age, sex, education level, preferred psychedelic drug (participants were only allowed to choose one agent), estimated number of lifetime psychedelic uses and history of micro-dosing (yes/no). In addition, given the exponential growth of interest in the use of psychedelics for mental illness, participants were asked if they were a healthcare provider who treats psychiatric disorders with medications.
