Experiencias de los participantes con microdosis de LSD en un ensayo controlado aleatorizado de 6 semanas

• The microdosing of LSD led to significant improvements in mood, social interaction, mindfulness, and creativity, but participants also reported experiencing heightened anxiety in certain situations.
• Experiences were characterized by bidirectionality, where participants noted both positive and negative effects on the same domains, depending on individual circumstances and their current emotional state.
• The findings highlight the importance of considering set and setting—participants’ mental state and environmental context—when evaluating the effects of microdosing.

Summary of Participant Experiences of Microdosed Lysergic Acid Diethylamide in a 6-Week Randomised Controlled Trial

This qualitative study explores the experiences of 40 healthy males who participated in a rigorous double-blind, placebo-controlled trial involving LSD microdosing. Participants ingested 10 micrograms of LSD every third day over a span of six weeks. While anecdotal reports of microdosing effects have proliferated, the researchers aimed to provide empirical insights into participants’ lived experiences in a structured trial setting, focusing on emotions, social interactions, and cognitive performance, among other parameters.

The authors clarify that microdosing is typically described as taking “sub-hallucinogenic” doses, meaning the outcomes are subtle and do not produce the strong perceptual changes associated with larger doses. Many individuals who microdose seek improvements in mood, creativity, and emotional stability, although some report adverse effects, particularly anxiety. A critical aspect of this study was investigating how external factors, or the combination of one’s mindset and environment (known as “set and setting”), influence these experiences.

Methods

Methodology and Positionality

The sample comprised 40 healthy male participants who adhered to a microdosing regimen. They completed a baseline assessment, followed by a single supervised dose at a clinic, before self-administering their subsequent doses at home. After completing their dosing schedule, participants were interviewed via video call to gain insights without the acute interference of the drug’s effects. The authors utilized content analysis, enabling systematic coding of the participants’ experiences and extracting shared themes across the group.

The authors disclose their positionality, acknowledging their familiarity with existing microdosing literature—which undoubtedly influenced their initial coding framework. They took steps to mitigate these biases by engaging in collaborative discussions and refining their codes through iterative processes. Ethical approvals were secured in New Zealand, ensuring the study was conducted responsibly.

Data Collection and Analysis

Using a semi-structured interview format, participants discussed a variety of potential microdosing effects two days after their final dose. This timing ensured that immediate drug-induced changes did not skew responses. The analysis began with broad categories based on existing literature, further expanded with inductively derived subcategories. Two significant themes, “openness” and “bidirectionality,” emerged universally from the transcripts.

Results

Findings reveal that participants experienced both enhanced moods and increased anxiety, highlighting the dual nature of their responses. In reporting emotions, many noted improvements such as increased positivity and resilience, describing the experience as an uplifting “little happy shot.” However, anxiety was noted to have a bidirectional aspect; while some experienced a reduction linked to self-compassion, others had increased anxiety, occasionally bordering on panic, often connected to overstimulation.

Social Life

Changes in social interactions were prominent, with participants frequently describing improvements in sociability and connection with others. Many expressed a newfound openness to engaging socially, characterized by feelings of warmth and connection. Conversely, some individuals reported increased introversion, demonstrating the bidirectionality of effects where lowered inhibitions could facilitate either positive interactions or self-consciousness about behavior.

Mindfulness

The mindfulness category captured a heightened appreciation for sensory experiences and emotional awareness, leading to greater enjoyment of everyday activities. Participants reported enhanced self-awareness and a more forgiving attitude toward personal mistakes, contributing to an increased sense of presence and contentment in the moment.

Cognition, Work, and Creativity

While broad cognitive enhancements were not widely reported, several participants cited specific boosts in creativity and willingness to take risks. However, experiences varied among individuals based on mood and the tasks at hand, illustrating the bidirectional nature again.

Physiological Effects

Physiologically, the primary effect reported was increased energy, although some also experienced fatigue. Other physical changes included jitteriness and mild discomfort. Variability in sleep patterns and minor sensory changes were also noted, with most effects being subtle.

Influences

External influences had a profound impact on participants’ experiences. Many noted that LSD could amplify their existing emotional states, leading to varying outcomes based on the surrounding environment. Expectations regarding whether one was receiving LSD or a placebo also played a significant role as some participants became preoccupied with such uncertainties, which hindered their relaxation.

Overarching Themes

The theme of “openness” referred to heightened emotional receptivity and willingness to communicate, while “bidirectionality” indicated that similar experiences could be perceived either positively or negatively depending on context and individual mood. Both themes underscore the complexities of microdosing experiences, highlighting the variability based on individual circumstances.

Discussion

The study illustrates that LSD microdosing can produce a range of both positive and negative effects across various life dimensions. Although many participants reported improved mood and sociability, notable incidences of increased anxiety were observed, echoing findings from previous quantitative studies. The authors emphasized the clinical implications for those managing mood disorders, as these pro-social effects may play a significant role in treatment.

Furthermore, the physiological effects commonly described as energizing also bring to light the need for careful consideration in dosing strategies, incorporating flexibility and adjustments as needed. The authors noted the temporary nature of reported openness, suggesting it may be situational rather than a lasting change. Bidirectionality was linked to individual differences and helped explain the diverse experiences reported. The importance of set and setting was also reiterated; being in a supportive environment seemed to amplify positive outcomes, whereas fear-inducing settings could provoke anxiety.

The discussion concludes by addressing research challenges within a placebo-controlled design, noting that the subtle nature of microdosing effects could lead to participant skepticism about their perceptions. Future trials may benefit from designing ways to consider expectancy and environmental context to yield a more accurate portrayal of microdosing experiences. The authors acknowledge several limitations, including sample demographics and potential biases due to participant familiarity with the interviewer, while emphasizing that this research offers a nuanced understanding of microdosing LSD within a controlled framework.
