Self-Rated Effectiveness of Microdosing With Psychedelics for Mental and Physical Health Problems Among Microdosers

This survey study (n=410) showed that those with mental & physical health problems self-rated the effectiveness of microdosing as higher than conventional treatments in regards to ADHD/ADD and anxiety. They rated it as less effective than a high dose of psychedelics.

Abstract

Background

There is a growing interest in the use of psychedelic substances for health related purposes, including symptom relief for disorders like anxiety, depression, and pain. Although the focus of recent clinical trials has been on high doses of these substances, anecdotal evidence suggests that low (micro) doses are also effective, and may be more suitable for certain conditions. Nonetheless, empirical evidence regarding the efficacy of microdosing with psychedelics for symptomatic relief is lacking. The present study aimed to investigate, by means of an online questionnaire, the self-rated effectiveness (SRE) of microdosing with psychedelics (MDP) for mental and physiological disorders compared to the conventional prescribed treatment and to regular doses of psychedelics.

Methods

An online questionnaire was launched on several websites and fora between March and July 2018. Respondents who had consented, were 18 years of age or older, had experience with microdosing and were diagnosed with at least one mental or physiological disorder by a medical doctor or therapist (N = 410; 7.2%) were included in the analyses. Odds ratio were calculated to compare the SRE of MDP with conventional treatment, and regular psychedelic doses for mental and physiological diagnoses for each of the three effectiveness questions (“Did it work,” “Symptom disappear,” “Quality of life improved”).

Results

Odds ratio showed that SRE of MDP was significantly higher compared to that of conventional treatments for both mental and physiological diagnoses; and that these effects were specific for ADHD/ADD and anxiety disorders. In contrast, SRE of MDP was lower compared to that of higher, regular psychedelic doses for mental disorders such as anxiety and depression, while for physiological disorders no difference was shown.

Conclusion

This study demonstrates that SRE of MDP to alleviate symptoms of a range of mental or physiological diagnoses is higher compared to conventionally offered treatment options, and lower than regular (‘full’) psychedelic doses. Future RCTs in patient populations should objectively assess the effectivity claims of psychedelics, and whether these are dose related, disorder specific, and superior to conventional treatments.

Research Summary of 'Self-Rated Effectiveness of Microdosing With Psychedelics for Mental and Physical Health Problems Among Microdosers'

Introduction

Interest in low, sub-perceptual doses of psychedelics such as LSD and psilocybin—commonly called microdosing—has increased in recent years. Users report taking roughly one tenth of a recreational dose to improve daily functioning, creativity and concentration while avoiding a pronounced altered state of consciousness. Beyond performance enhancement, anecdotal accounts and interview studies indicate people also microdose to alleviate psychological and physical symptoms (for example anxiety and headache). At the same time, most clinical evidence for therapeutic effects of psychedelics has derived from regular, full doses that produce a profound acute experience; whether repeated low doses have therapeutic value remains unclear. This study set out to assess self-rated effectiveness (SRE) of psychedelic microdosing (MDP) for diagnosed mental and physiological disorders. Using an online questionnaire, the investigators compared respondents’ retrospective ratings of microdosing with (a) their conventional prescribed treatments and (b) regular (full) psychedelic doses, across three effectiveness questions: whether the treatment “worked,” whether symptoms disappeared sufficiently to restore daily functioning, and whether quality of life improved. The aim was to identify disorder-specific patterns in self-reported benefit and to inform priorities for future randomised controlled trials (RCTs).
