I was introduced to LSD in 1965. In the years that followed, other than the mystical, or peak experience, my aim was to hit that ‘sweet spot’, where vitality and creativity are enhanced, while leaving me in control of my concentration. I grew to love this state. It was, in a way, comparable to what people are doing today with microdosing” – Amanda Feilding


About Microdosing

The practice of microdosing entails taking low doses of psychedelics, which are usually one-tenth of a recreational dose that causes a psychedelic experience. For LSD, that would, for example, be between 10 and 20 μg. These may be taken repeatedly, every 2 or 3 days over the course of several months, or more occasionally.

Taking small doses of psychedelics to affect mood and performance is growing in popularity. However, there is very little research to back the validity of certain claims, which include improved cognition, productivity and mood.

Amanda Feilding and the Beckley Foundation, together with its research partners at Maastricht University and a selection of academics across the globe are seeking to uncover more information, to both assist with harm reduction among those microdosing in their daily lives, but also importantly to support the evidence-base for the introduction of possible psychedelic medicines.


The Beckley Microdosing Research Programme

With the Beckley/Maastricht Programme, we are conducting a series of placebo-controlled microdosing studies to investigate in great detail this increasingly popular practice, and its potential therapeutic applications.

Our first study, investigating the effects of various small doses of LSD on mood, cognitive functions, and tolerance to pain, has been completed in 2019, with ground-breaking results demonstrating for the first time in the lab the benefits of LSD microdosing.

Following up on this success, we are now looking at the efficacy and safety of a fixed microdose of LSD administered repeatedly over a period of four weeks, on brain activity, cognitive functions and mood. Of particular interest, this study will be investigating whether LSD microdosing, when used once or repeatedly, can amplify brain plasticity, a phenomenon that has already been observed in cells, lab grown ‘minibrains’ and animals, but not yet in humans.

Outside of the lab, the Beckley/Imperial team have also been conducting the world’s first placebo-controlled, self-blinded study of microdosing. Recruiting participants from around the world who already microdose, or who are about to start, the study used an innovative new procedure to mimic important aspects of the blinding process, improving on previous survey studies of microdosers by diminishing the role of the placebo effect.

Given our current understanding of the mechanisms of action of psychedelic compounds such as LSD, this pioneering work could lead to LSD becoming a possible treatment for a range of conditions in need of more efficient treatments such as mood disorders, age-related cognitive decline/mild cognitive impairment, chronic pain, brain rehabilitation, and addiction. The Beckley Foundation is already starting to initiate research projects exploring these potential therapeutic applications.

Finally, at the Beckley Foundation, we are convinced of the value of ‘grassroots’ approaches to psychedelic research, and we have started collaborating with Quantified Citizen and an international team of researchers (including mycologist Paul Stamets) on a large international remote microdosing research platformAs part of this collaboration, we are conducting a study on microdosing and meditation, aimed at better understanding the potential use of microdosing as an aid to meditation practice.
