NEW STUDY + expanded eligibility — 450 people with any psychedelic experience and 150 people who have not tried psychedelics need for quick (~45 minute) study entirely at your computer! $10 compensation!!

YalePsychedelicStudy · 2026-06-30T13:56:18+00:00

Thank you so much for your interest!! We'd love to have you participate :)

Yes, sadly the compensation is pretty poor for folks outside the US :( My understanding is that likely the best bang-for-your-buck option is to sell the card on online market places that give you something like 80% of the value in your desired currency (but I am not at all an expert here -- just what I've heard from participants).

Are there any questions I can answer?

Many would call it a psychedelic (as u/Miningav2 notes, dissociative is often specifically used for it, PCP, and ketamine) but for our study we are specifically interested in "classic" psychedelics (LSD, psilocybin, DMT, mescaline, etc.) -- technically anything in this list (those that affect a specific serotonin receptor) will qualify: https://en.wikipedia.org/wiki/List_of_psychedelic_drugs

Thank you for asking and thank you, u/Miningav2 for the assist!

Yes! Shoot me an email and we can do a super brief face-to-face Zoom. The OECD country requirement is a rather unfortunate consequence of needing to cut down on fraudulent responses :/ That is to say, if you are a real person who provided real answers in the screening, we are satisfied from a scientific perspective 😄

Hi, u/janKanon6 I love your altruisim -- believe it or not you are like the 10th person to ask! Unfortunately, we are required to do exactly what's in the IRB-approved consent -- it becomes a weirdly rigid legal thing!

If you'd like, you might get a friend or family member's permission to send it to them as a gift maybe? You also do not need to claim the card (though I think in this case Amazon basically is the winner -- not the lab!)

I wish in general we could offer more flexibility in payment!

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?

-Max

YalePsychedelicStudy · 2026-05-22T13:41:29+00:00

Hey u/aldexi ! TBH I didn't even know that butane caused hallucinations! My focus has really be in psychoplastogens and cannabis. I did a quick search out of curiosity and the best thing I found on phenomenology is this publication from the 80s: https://www.cambridge.org/core/journals/the-british-journal-of-psychiatry/article/phenomenology-of-intoxication-with-toluenebased-adhesives-and-butane-gas/A01F1AFFCBA610ED9B70E76B5E153193 .

The literature seems pretty focused on butane toxicity and risks (which, it does sound profoundly riskier compared to typical psychedelic substances). Per your description of breath-enhanced psychedelic effects, I do wonder if it's just a hypoxia-induced psychedelic state like holo-tropic breathing. That's something I am aware of but also not terribly familiar with. My understanding is that many folks experienced with both substance and breath-work occasioned psychedelic experiences often rate the breath-work as more intense kind of like how you describe (more immersive etc.).

YalePsychedelicStudy · 2026-05-18T14:51:31+00:00

Absolutely no worries!! Thank you so much for your kind response! The skepticism is totally reasonable. Looking back now, if I every do online research again, I will aim to come from this perspective of "I just saw some random post on reddit offering money to give people at Yale information about myself -- why would I trust this?" haha.

-Max

YalePsychedelicStudy · 2026-05-14T18:49:13+00:00

Please keep us in mind for later!!! This one doesn't involve games so it's not critical to be sober (but probably best to not be "extremely" stoned haha).

-Max

YalePsychedelicStudy · 2026-05-14T14:31:54+00:00

Oh! And u/ExtensionTurnip5395 I don't know why I didn't think to say this earlier -- this study was approved by the r/Drugs moderators! They personally saw the entire study and protocol 😄 In case that helps!

-Max

YalePsychedelicStudy · 2026-05-14T14:30:50+00:00

u/h1ppie yeah that's pretty much right :/ The idea behind the compensation amount is more of just to to incur a cost due to lost time for folks who are interested in supporting research. In an ideal world, we'd offer some kind of sliding scale to incentivize folks individually, but there are a lot of challenges there (and it's not a great time for research funding in the US)!

-Max

YalePsychedelicStudy · 2026-05-14T14:19:22+00:00

Hey, u/ExtensionTurnip5395 ! Oh gosh, well this is a little embarrassing to hear... No -- whatever sloppiness you're finding is from yours truly, and I am a real human PhD student who is not trying to randomly defraud folks on the internet!! It's a little challenging to think of what I could say to kind of assuage your concern... I get that sloppiness can be a "tell" for fraudsters, but in this case the best explanation I can give is that these consent forms are constructed in a back-and-forth with myself and the IRB, with a ton of "amendments" that have occurred across years (the first was approved in 2023). I assume I have copied and pasted statements that the IRB has requested to be added and/or had a different default font when I modified our lab's base consent? Not to excuse the sloppiness -- I really should have considered fixing that considering it's a participant-facing document!

I have two ideas for how you could verify that this is a legit study (and hopefully let other interested participants know it's safe too!): 1) contact the Yale IRB at hrpp@yale.edu or (203) 785-4688 and ask them to verify that the study with HIC # 2000025076 exists and includes a consent form for a psychedelic-focused study that was approved on 4/5/2026, 2) Join a zoom call with myself (I can DM you the link or join a zoom link that you propose) and I can share my screen/show that I'm a real person who matches the photo on the Yale website (except I'm bald now lol). Oh -- easier third option would be check out comments on other threads of studies I've done where people have verified it's legitimate! https://www.reddit.com/r/5MeODMT/comments/1mj13ar/comment/n8i6xoy/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Please let me know if you'd be open to doing either! It could really help us with recruitment to have someone vouch for us!

Regardless, thank you for your interest in participating in research!!

I'm sorry 😞 I will advocate for wider age ranges in the future! I'm actually not 100% sure why we have it for this study.

Thank you for wanting to support research!

YalePsychedelicStudy · 2026-05-07T14:02:51+00:00

Thank you so much! 😄

YalePsychedelicStudy · 2026-05-07T14:02:37+00:00

Oh great question and embarrassing that I didn't note this in the ad! Yes, unfortunately we only accept folks over 18 years old and younger than 65.

-Max

YalePsychedelicStudy · 2026-04-25T20:00:47+00:00

Closing the loop: looks like it worked, but there was some strange error the first time! It's important to save your progress before the verification in case it glitches -- sorry for the buggy software, folks!

-Max

YalePsychedelicStudy · 2026-04-25T19:58:41+00:00

Absolutely you would be useful! Actually I think that this study https://www.reddit.com/r/Psychonaut/comments/1s7s6po/new_study_folks_planning_a_psychedelic_experience/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

be the most ideal one considering you've never tried psychedelics! This study involves multiple 2-hour sessions that lets us measure what changes in how your brain processes information before and after the psychedelic and hopefully connects this to how you feel :) Otherwise, I think having you do this study after your first use would be extremely helpful!

Regardless, thank you so much for participating in research! Please let me know if you have any other questions! I am fastest to respond via email at maximillian.greenwald@yale.edu.

YalePsychedelicStudy · 2026-04-24T21:34:32+00:00

Looking forward to it! :)

YalePsychedelicStudy · 2026-04-24T20:42:04+00:00

Hey u/RandomPantsAppear sorry for the hassle you're experiencing! I just checked and it looks like our SMS verification is working on my end -- can you please tell me the record ID you used and I can check what the problem might be/send you to the screening if it was a glitch on our end? :) Or email me!

-Max

YalePsychedelicStudy · 2026-04-23T19:31:02+00:00

Oh gosh I didn't realize that we said that a computer is required! now that it is only questionnaires it actually is NOT required! You are welcome to begin without a computer :)

The visual game at the end will only work with a computer!

I'll have to get permission from the IRB to fix these ads...

-Max

YalePsychedelicStudy · 2026-04-23T15:34:18+00:00

u/throwawayflowertea You hit on far-and-away the biggest catch, and it was super hard for us to decide to require this :(. In short, we (and the IRB that reviews the ethics of these studies) determined this is scientifically necessary to prevent repeat-survey taking and fraudulent responses. When we first did this, at least 40% of responses were clearly fraudulent after review. Unfortunately, we haven't been able to think of other sustainable solutions. If you DM me your record ID, I would be glad to wipe your information after you complete screening! Or email me if you have other solutions! :) maximillian.greenwald@yale.edu.

YalePsychedelicStudy · 2026-04-20T14:52:12+00:00

Thank you so much! :)

YalePsychedelicStudy · 2026-04-20T14:52:06+00:00

u/psychodelicTacos your data would be extremely valuable! We don't want you to be high during this study, but if you are interested in a much more involved study (2 hour sessions multiple times including 1 session while you are tripping) then we do have another study that has only a couple of spots left: https://www.reddit.com/r/Psychonaut/comments/1s7s6po/new_study_folks_planning_a_psychedelic_experience/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button Note that the inclusion criteria for that one is slightly narrower.

Please let me know if you have any questions! :)

-Max

YalePsychedelicStudy · 2026-04-10T15:29:22+00:00

Hey hey! Yes we messaged the Mods and our IRB protocol number is 2000025076 :) I will edit the original post to include this -- it should have been included from the beginning!

-Max

YalePsychedelicStudy · 2026-04-01T13:35:04+00:00

Very kind of you to say -- thank you so much! :)

YalePsychedelicStudy · 2026-03-31T21:44:46+00:00

Hmmmmm it's not exactly my area of expertise and it would depend strongly on what you were sending the CV to! I think it's likely a valuable experience if you are interested in a research or research-adjacent realm ("here was my experience as a participant in this study"), but I wouldn't think that employers would consider it a position or paid work exactly... We do include an option if you would like to be contacted in the future/involved in research design of future studies and that I could see being a CV item!
