Call for participants in Maastricht University's LSD micro-dosing study

Maastricht University is conducting a study regarding the effects of microdosing with the psychedelic substance LSD on subjective and cognitive measures. For this, they are still looking for a broad cross-section of healthy volunteers, between 18 and 65 years of age, who want to participate.


Microdosing is the practice of taking low doses of LSD in order to enhance creativity, mood, and/or other aspects of performance, and it has gained considerable coverage by international media. While the acute effects of taking one microdose of LSD have been examined; the effects of repeated microdoses on subjective and cognitive effects are still unclear.


The study will use repeated LSD doses, and compare their effect to a placebo (inactive substance) on measures of behaviour and subjective experience in healthy participants. This study can give a first hint to whether microdosing can be of value in psychiatric populations that exhibit certain emotional or cognitive symptoms. For instance, an increase in positive mood might be beneficial for individuals who suffer from mood disorders. Or for example, if attention improves after prolonged microdosing it might be beneficial for individuals who suffer from attentional disorders.


Participation will last about five weeks in total and consists of seven visits; a medical screening followed by a training day, a baseline visit, four microdosing visits (LSD or placebo) and a follow-up visit. The baseline visit, two out of the four microdosing visits and the follow-up will consist of a whole day of testing and will take up to 6-7 hours. The other two microdosing visits will only last around 1.5 hours. In addition, participants will be asked to fill in some questionnaires at a one month-follow up session.


Those interested in participating in this study, please contact the research coordinator Nadia Hutten by sending an email to fpn-epuonderzoek115@maastrichtuniversity.nl


The researcher then will send some questions about general health and drug use. If, on the basis of answers to the questions, applicants meet the inclusion criteria, they will be invited for a medical examination. Participation will be reimbursed and paperwork for permission to travel cross-border for inclusion in the study will be supplied.
