Cohort study, also known as the "Psychedelic Survey" study, was the initial study conducted using Psychedelic Survey. The focus of the study was to look into the effects of psychedelics taken outside of a clinical context.

The Microdosing Survey Study was done by the Psychedelic Research Group at Imperial College London. The aim of the study was to collect data on the process of microdosing a classic psychedelic substance (i.e. psilocybin, LSD/1P-LSD, ayahuasca, AL-LAD, salvia divinorum, DMT, 5-MeO-DMT, iboga/ibogaine or mescaline).

The psychedelic ceremony survey was a project run by the Psychedelic Research Group at Imperial College London. Its aim was to collect data on the psychological effects of guided psychedelic and plant medicine use, ranging from healing ceremonies with ayahuasca to supervised ibogaine treatment.

The goal behind Self-blinding microdose study, developed by Balazs Szigeti, was to test whether psychedelics microdosing has any effects beyond the placebo on psychological well-being and cognitive function.
