The effect of low doses (<=20 μg) of LSD on working memory, in the absence of altered states of consciousness, remain largely unexplored. Given its possible effects on serotonin 5-HT2A receptors and dopaminergic signalling, it could be hypothesised that LSD microdoses modulate working memory recall. Moreover, in line with computational models, LSD microdoses could exert antagonistic effects on...

Microdosing psychedelics is the regular use of sub-perceptive threshold doses of substances such as lysergic acid diethylamide (LSD) and psilocybin ('magic') mushrooms. The phenomenon has attracted increasing public and scientific attention in numerous countries in recent years. This commentary looks at microdosing psychedelics as an emerging facet of human enhancement through drugs. After...

Background: Microdosing psychedelics is the practice of taking small, sub-hallucinogenic doses of lysergic acid diethylamide or psilocybin-containing mushrooms. Despite its surging popularity, little is known about the specific intentions to start microdosing and the effects of this practice. Aims: First, we aimed to replicate previous findings regarding the subjective benefits and challenges...

The regular consumption of very small doses of psychedelic drugs (known as microdosing) has been a source of growing media and community attention in recent years. However, there is currently limited clinical and social research evidence on the potential role of microdosing as therapies for mental and substance use disorders. This paper examined subjective experiences of microdosing...

BackgroundThe practice of "microdosing," or the use of repeated, very low doses of lysergic acid diethylamide (LSD) to improve mood or cognition, has received considerable public attention, but empirical studies are lacking. Controlled studies are needed to investigate both the therapeutic potential and the neurobiological underpinnings of this pharmacologic treatment.MethodsThe present study...

BACKGROUNDMicrodosing of psychedelics such as LSD consists in its regular ingestion of a non-hallucinogenic dose. Advocates deny experiencing the typical alterations in consciousness while reporting various long-lasting psychological benefits.It has been under research for treatment of mental health disorders including end-of-life anxiety, drug abuse, and depression. Increased accessibility in...

These mixed-methods results help summarize and frame the experiences reported by an active microdosing community as high-potential avenues for future scientific research. The MDBC taxonomy reported here informs future research, leveraging participant reports to distil the highest-potential intervention targets so research funding can be efficiently allocated. Microdosing research complements...

Albert Hoffman suggested that low doses of LSD might be an appropriate alternative to Ritalin. Following this possibility, a systematic exploration of the effects of "microdoses," comprising hundreds of lengthy descriptive reports, was undertaken. Based on these reports, using a psychedelic in the microdose range (10 micrograms) every three days was determined to be safe across a wide variety...
