[Survey seeking feedback] A Comparative Study of Psilocybin Mushroom Species

Attention all Nexian psilonauts,

I've just launched a new survey study focused on systematically investigating the subjective effects attributed to different psilocybin mushroom species. The survey is anonymous and should only take a few minutes of your time.

Our goal is to enhance the scientific understanding of these experiences and their potential variations across species, with a focus on commonly-used, psilocybin-containing mushrooms.

Research Objectives: This study seeks to identify patterns and distinctions in the subjective experiences elicited by various psilocybin mushroom species, addressing questions such as: Do different species cause different subjective effects? Do certain effects always co-occur? Are there a set of clusters into which we can group species depending on their effects? And many more! Your input as an experienced user is critical in enabling us to discern these patterns, contributing to a more nuanced understanding in the field of fungal psychopharmacology. This is especially the case for those of you experienced with species that are less frequently used.

Your Participation: In the following, we will present you with a list of psychoactive mushroom species/varieties and ask you to select those species that you have used at least once in the past 12 months. For each of those species, we will then ask specific questions to capture the qualitative aspects of your typical experience with this species. This includes sensory perceptions, cognitive changes, and emotional responses you associate with each species.

Are there any risks? What happens to the information I provide?

We do not expect that your participation in the study will expose you to more psychological distress than you experience in your daily life. You will not be asked for information that would identify you beyond beyond reasonable doubt. Demographic information assessed will be minimal, and you are free to skip these questions. To ensure full anonymity, no further identifying information (e.g., IP-addresses, operating system, browser info) will be saved by Qualtrics. If you change your mind about participating in the study, you are free to leave the study at any time (by closing the browser window) without providing any reason.

Your responses may be used by the research team for data analysis, shared with other researchers, or made available to other researchers in an online data repository. Please note that once you have fully completed participation in the study, your data cannot be identified and therefore cannot be withdrawn. If you have serious concerns about the ethical conduct of this study, please inform the University of Zurich Ethics Committee in writing, detailing your concerns.

Link to survey is below...all & any feedback is much appreciated! 🍄🙏🙂

Hi fun'gi's & fun-gal's, thanks a lot for all and any feedback so far, it's much appreciated! Starting to get some good feedback where we should hopefully start to be able to make comparisons between some of the more commonly used species, but the more data we obtain, the better - it would be amazing if we could net some more data on people's experiences with such as Pan cyan, P. natalensis, P. semilanceata and Ps. cyanescens.
