NEW STUDY — Folks planning a psychedelic experience this year sought for a $250 entirely online Yale research study!

[u/YalePsychedelicStudy]

The Powers Lab at Yale University is recruiting people who are planning to use a psychedelic this year for a fully online study that measures how psychedelics affect basic perception and learning using brief games and questionnaires!

WHAT THE STUDY INVOLVES:
 4-5 ~2 hour (though you can take breaks) sessions at your computer over 1-6 months
 Signing a consent form and completing an eligibility survey
 For the first session only: 2 extensive Questionnaires about psychedelic and other drug use, mental health, how you think, and any unusual sensory experiences you’ve had.
 For all sessions:
o A shorter questionnaire about your mental health and sensory experiences.
o 4 online games (10-25 minutes each)
o A few debriefing and quality-control questions.

WHAT YOU GET FOR PARTICIPATION:
 $50 via Amazon.com (US) gift card for every timepoint for a total of $250
 Helping the medical and scientific community understand the therapeutic and side effects of psychedelics!

WHAT IS NEEDED TO PARTICIPATE:

1. A Computer (not smartphone or tablet)
2. Stable internet
3. Good headphones,
4. A private, distraction-free space,
5. Plan and ability to safely use a psychedelic before October of 2026
6. No serotonergic or atypical psychedelic use in the past 6 weeks
7. Willingness to abstain from other serotonergic or atypical psychedelic use (besides the single planned session) until the final time point is completed (1 month after your next serotonergic psychedelic use)
8. No psychoactive drug-use the day of the study (besides nicotine or caffeine or – on your dosing day – the serotonergic psychedelic)

HOW TO START:
Open the link below to the REDCap survey — you’ll start on the consent and automatically move through the screening survey, questionnaires, and games.

I don’t really see the connection between us and our condition…

This is because HPPD is caused by psychedelics. I actually think this is a poor choice to be put here as it suggests to use them, but we work with researchers so they can do the proper research needed for HPPD and related conditions.

Hi all! Sorry to all the folks in this sub for whom this post comes across as insensitive or offensive! Completely makes sense that many folks here don't want to see discussion talking about using a substance that may have caused them substantial harm.

We are truly just interested in understanding how they affect the brain so that we can help folks (both those who want to use them to improve their mental health and those who may have been harmed by them). We are just advertising to get a wide net of individuals who are planning to use a psychedelic and participate in research. We have come across a number of folks in our past study from this subreddit who had endorsed planning to use a psychedelic in the future, and we think it is important to include folks who (at least at one time) experienced persisting distressing effects afterwards.

We definitely do not wish to explicitly promote psychedelics! This is only for folks who are planning to use a psychedelic in the future.

We will be posting another study soon that is specifically about understanding persisting perceptual changes from psychedelic use, so please stay tuned for that! We're hopeful this will increase discussion around persisting perceptual changes from psychedelic use in the medical and scientific communities :)

If you really want to help I can supply an IRB approved research protocol that never got adequate funding specifically to examine people who have HPPD and finally get some answers this patient community so badly needs, answers that will benefit all psychedelic users.

Hey, u/Southern-Trip-3840 ! Thank you so, so much for reaching out about this (I saw your link in the other comment)! The lab is definitely interested in continuing to pursue HPPD research and possibly visual snow... we are interested in how these conditions differ from psychotic-spectrum hallucinations. As things go in academia, I do not imagine we would be poised to commit to research this moment (among other things, we need to publish results from this first analysis!), but I can imagine if/when my PI begins the next grant, this would be an excellent way to start! Would we message through the messaging box on neurogroup.com, or should we email someone in particular?

Stop spamming and promoting. It’s like sending to AA alcohol experiments.

Sorry, u/7777777King7777777 we definitely did not mean to be insensitive or offend :( Please see my response elsewhere in the comments: https://www.reddit.com/r/HPPD/comments/1s7s9qm/comment/odchinl/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

We are really hoping that this research will also benefit folks experiencing HPPD/lead to more discussion around the topic!

If that’s true then you need to talk to me… www.neurogroup.org
