The State of Psychedelic Research – Rotem Petranker

In this episode of AmeerApproved, I sit down with Rotem Petranker to talk about the state of Psychedelic Research especially the research he is doing on Microdosing and why it is imperative that we have Open science standards 

“A first study of microdosing”

Microdosing psychedelics, such as lysergic acid diethylamide (LSD) and psilocybin, has become a recent media phenomenon, yet scientific studies verifying its effects are absent from the literature. To begin addressing these gaps in knowledge, we measured the microdosing drug practices and psychological functioning of existing communities engaging in this activity, in the first ever microdosing study. This pre-registered online study involved 1390 participants, some of whom were microdosers (either presently or in the past), and some of whom were non-microdosers (either interested in trying it in the future or not interested in microdosing). Our results suggest distinct patterns of microdosing in the population, as well as significant difference between microdosers and non-microdosers on several personality and well-being measures such as negative emotionality and wisdom. This research will serve to inform individuals already microdosing, the scientific community, and policymakers in the future.


Rotem Petranker is a master’s student at York University, working with Dr. John Eastwood. He is interested in cognition as a space to traverse in which scaffolding and shortcuts are available. Examples of scaffolding include language in general and metaphor in particular; shortcuts include creativity in general and insight in particular. Movement in cognitive space requires the expenditure of attention, which is another one of Rotem’s main theoretical areas of interest. Rotem is interested in the effects of certain practices, such as psychedelics and meditation, have on cognitive space.
