Hi there, We are doing a psychology research study on HPPD as part of the University of West London. The title of this project is “Do anxiety and depression have a relationship with HPPD in relation to age and ethnicity?". We are inviting you to take part in a short online survey, and your participation would be entirely anonymous. This survey will only take 10-15 minutes. Anyone aged 18 or over can take part. This study is exploring an area of HPPD that is still unknown and has not been investigated before. This is because we are investigating not only the potential relationship between anxiety, depression and HPPD, but also how the demographic factors of age and ethnicity relate to this. The findings of this study could encourage far more research, expand our knowledge of HPPD and lead to a deeper understanding of how we can treat HPPD, and so the study may be published at a later date. If you would like to find out more or you are thinking about becoming a participant in this study, please select this link to open the survey and information form: https://uwlpsych.eu.qualtrics.com/jfe/form/SV_6KBMKL1jBgi5eWq Thank you for taking the time to read about our study. Yours sincerely, Romy Misra and Leanne McDonald

EPISODE 1: Your Privacy, Research Methods and Introduction for HPPD Patient-Researchers. We all have different experiences with doctors and our families when it comes to getting support for HPPD. One major barrier to getting information is a reasonable concern of wondering how people will judge you and how can publicly admitting this diagnosis be a challenge for your life. I can tell you that it isn't easy, and from my experience majority of people that visit this site do not become members and I think there is wisdom to this. Can we do better? What are the risks of Facebook Groups? (I will show you how I can mine your data across multiple social platforms as long as you like my page or join a group.).

June 11, 2019 SUBJ: Faces of HPPD Survey/Research Published – RESULTS! Dear HPPD Online Community: As a mom with a grown son with HPPD, I was so fortunate to come across this forum several years ago for information and support. David Kozin, who runs this board, is an amazing man to have created and maintained this website and kept up his work/studies over the years – all the while suffering with HPPD. I would like to thank him for this platform, and well as thank those of you who participated in the survey that I launched four years ago to collect data about individuals who had received an official diagnosis of the disorder. Fast forward…. Here it is June 2019. Long overdue for the published report, however, I lingered – always hoping to gain a larger sample of subjects. I am fortunate to have a PhD in psychology, experience in research, and a heart to try to make a difference. Instead of publishing a book, it only made sense to get the results in the hands of the scientists and medical professionals through scientific writing. I am so happy to tell you… the peer-reviewed medical journal, Addictive Disorders & Their Treatment, published by Wolters Kluwer publishers, has reviewed and accepted my manuscript for publication in an upcoming issue. Last week the article completed rounds of publication editing and formatting. The article is posted at their website for advance release. Lewis, DM, Faces of HPPD: Hallucinogen Persisting Perception Disorder Patient Survey Results and a Descriptive Analysis of Patient Demographics, Medical Background, Drug Use History, Symptoms, and Treatments. Addictive Disorders and their Treatments. Forthcoming 2019. The link is here: https://journals.lww.com/addictiondisorders/Abstract/publishahead/FACES_OF_HPPD__Hallucinogen_Persisting_Perception.99733.aspx (NOTE: This direct link will change probably in a month or two when the article is given a print-issue date – right now, it is advance copy, undated. In the future, you can search the article at https://journals.lww.com/addictiondisorders/ . While the article is available for immediate download, many of you know that publishers charge money for copy downloads (this one is $49), and authors cannot give away their copy. This, I know, is not a good thing for some within the community who do not have the funds. However (here’s the good news ), I contacted the publisher and obtained permission to publish a summary of the results (the important data!) and I created an infographic that provides you all the results. I am including it here as a .pdf file, attached. It’s reader-friendly, and I hope it provides insight. I want to mention some findings that particularly concern me: the high rate of suicide ideation (among other co-morbid psychological/psychiatric symptoms reported), and the significant number of individuals who reported being unable to work due to HPPD. I feel strongly that HPPD needs recognition as potentially disabling – and I believe there are some individuals who may need government assistance (eg, Social Security Disability benefits). My future work leads me in the direction of carving a path for HPPD as a qualifying mental disorder for eligibility for assistance. I will keep you posted on that. Again, thank you so very much for those who partook in the survey. My best wishes to each of you for good health and peace of mind, Doreen M. Lewis, PhD https://www.facesofhppd.com https://www.vellichorresearch.com Faces of HPPD Infographic - LEWIS.pdf

Hey guys, I posted my survey link on the introductions page some weeks back. I just thought I'd put it out here again. The survey will be online for around 2 weeks longer so wanted to make sure anyone who might be interested gets the chance to participate. The survey will take around 15-20 minutes to complete depending on responses. The survey is investigating individual differences in those experiencing HPPD. The project is supervised by well-established psychedelic researcher, Dr. David Luke. The survey has been ethically approved by University of Greenwich, UK. If you haven't completed it and are interested to participate it would be much appreciated! Thanks, Alex https://greenwichuniversity.eu.qualtrics.com/jfe/form/SV_9tPkqFu2yAaNHOl

I am here for several reasons. Foremost, my 23 year old son has HPPD and I am personally touched by this. His struggles parallel what others feel and experience as written here. Living with HPPD is a private hell – seems. It is met with misunderstanding and judgment from an insensitive society and an uninformed professional medical community, generally speaking, with exception of very few doctors who are HPPD champions. It seems most members here are unofficially diagnosed… seeking information what to expect, where to go, how to feel better, lead life unencumbered. What a Godsend this forum is. I am here because I believe HPPD sufferers need advocacy… This means caregivers and the community leaders are needed to speak for them when they cannot, to represent their needs, to make a difference, to carry a torch and make inroads in research and awareness. To YOU, I extend my hands to help, my heart, my time. I am a psychologist, researcher, and writer…. and I care very, very much. So many faces, different places, the stories so similar…. Too little resources, no place to turn, just each other to help. I am only one person, but bring it on… and let’s get started to do something good. Please visit my website, Faces of HPPD www.facesofhppd.com which is established as a project to compile information about HPPD from those who have received official diagnosis and treatment, so that all can learn about living with HPPD. Faces of HPPD is not intended to compete with this forum… but to expand the sharing of resources and knowledge. I hope in some way I can be a force to make a small difference. God speed to each and everyone of you! Doreen Lewis, PhD (in Florida)

Hey guys. I would like to help the community and myself to find some ways to treat HPPD. This forum is great for talking about our problem, but I think its lacking some organizational features that are very important to connect all the dots. Also there is lot of digging to be done to find all the useful informations scattered around the forum topics. I think apart frome the forum we need something extra, something organized. My idea is to build a website with specific functionality. Sort of a HPPD Encyclopedia. Rough sketch of my idea - the website would have: Database of users. Each user would have his profile, where he could include information like: - His story of HPPD (possible causes, duration, przebieg???? etc.) - What has helped ( name of the drug/supplement/treatment/excercise, how he reacted to it/comment side effects) (X) - What has harmed him ( name, reaction/comment, side effects) (Y) - What hasn't affected him ( name, reaction/comment/ side effects) (Z) - What he plans to try - Other comments, ideas, experiences. Database of drugs/supplements/treatments/excercises - this would be a list of all the drugs etc. next to every drug there would be number of positive, neutral and negative votes (how many people it did help, did nothing, harm them). Users could click on any drug/supplement etc. and see information like: - Name - Description - Interactions with other drugs - Side effects (especially the side effects reported by people with HPPD) - List of all users that it has helped (name of user, reaction/comment) (X) - List of all users that it has harmed (name of user, reaction/comment) (Y) - List of all users that didn't notice change (name of user, reaction/comment) (Z) Now look at the X, Y and Z. Whatever user would input into his profile, that information would be listed also under each drug/supplement etc. This way if few hundred people write out their experiences with different things, we will get a good statistical data on each of them, and will be able to draw some conclusions. If we want extra functionality, one page could be like a facebook wall - showing the latest activities, but lets focus on the basics ones first. Graphics design - we want to make it as simplistic and cheap as possible. I think this is a tool, that would give us good view on the matter and would ensure that no information gets lost. For example, I found one post on some polish website saying Vinpocetine helped somebody with VS. That was only 1 post I found thorough the internet on vinpocitine and VS. I could report that information on the website and then other people could try it out if they wanted to. Having this kind of website, would save us jumping from post to post on forum or facebook groups and whatnot - all the information we want would be in ONE place. Maybe some pattern will emerge like - people who got HPPD from antibiotics get relief from the drug "x", people who got HPPD from acid are most likely to get help from the supplement "y". On that website we could encourage people to do DNA tests to see patterns in them too and so on.. On the website we could include all the information we have on HPPD, its description, causes, together with any scientific reports - this would be great then to present to doctors, professors, scientists etc. I think its gonna be a great portal for spreading awareness about the condition and its severity. One will be able to actually see how many people are affected by it. I am not a website coder - I am more of a visioner. I hire people to build websites for me. I would love to be able to do it for the community but at the moment however, i have no cash - I am after being very unlucky (or stupid) with my investments. If there were people interested in creating such a website we could share the ideas of what functionalities we want on the website to be. There are some ways to go about it: - If there is any webdesigner in this community, that would be willing to do the website for us - that would be great. - We could make a fundraise and then decide whos gonna do the website. I am willing to spend my time on supervising the construction and improvement of the website. I don't know yet how much could it cost. Yesterday I talked with a friend of mine, he said this kind of website could take him anything from 30 hours to do. He made a note, that if we get somebody from internet to do it its probably gonna take more. I don't know how much he charges yet and if he is gonna have time to do it ( he will let me know soon) - however im living with this guy right now, he is a cousin of my best friend, which means - he would not rip me off for one cent - which I believe happens in this industry a lot. If we get somebody to do it remotely, there is no way of veryfing how much time he actually spent on the website etc. This friend of mine is programming and building websites all his life, working in a corporation etc. basically he knows what he is doing. He could commit 4 hours every weekend to build this website, which would mean it could be finished in let say 2 months. This is not by any means a way to try to make money - anybody interested will be able to view commits (new code added) and verify the work. My rough estimate is that the website could cost around 750 euro, but lets wait and see what the guy will say. However from my experience its good to assume its gonna be little bit more expensive. On the website we could post some adds and the money from it could go to the website development or any future HPPD researches - or we could have no advertisement, thats up to the community. I believe however that we do need some cash. Please let me know of your thoughts - all comments are valuable. my contact hppd90@wp.pl , facebook: Pablo Esscobar from Rio De Janeiro Pablo

Hi everybody. I hope im not crossing any rules of the forum by this post. I think this is a really important matter, so I have let myself risk it and post about it in other sections of the forum too to reach as many people as possible. Plus people from outside the forum, couldnt access the beyondhppd online section. Please check out this post. http://hppdonline.com/index.php?/topic/4459-i-have-an-idea-for-a-website-that-could-help-us-in-finding-solutions/ Thanks

I came across SciOpen Research Group (SRG), and thought: "Awesome!". They now have an IndieGoGo campaign to raise funds for microscopic tissue analysis to assess the effects of J147; a potent neurotrophic Curcumin derivative that's orally active. They are a self-proclaimed "Guerilla Biotech" research group. I'll just post the video, so you can see for yourself: Bridging the "Valley of Death": Introduction to SRG: https://www.youtube.com/watch?fv=4x4efcbRRWg Now their main focus is ALS, however this is just their first project. They are interested in any neurogdegenerative disorders. Now I'm not saying they'll be interested in HPPD, or if they can even do something for it, but I just wanted to post this as I found it an inspiring example. Perhaps, if they are successful, more initiatives such as this will take off, and somewhere along the line HPPD may become a focus of research as well? Or, whatever fruits such endeavours bear, may be applicable to us. Either way, I found it post worthy.

I found this article published in June of 2013. It's definitely worth reading. I tried uploading the pdf file in research articles, but the file is too big.

Hey everyone. As some of you might know, David Kozin is in the early stages of writing a book on the dangers of the use of the term "flashbacks" in a diagnostic setting. The book will introduce people to HPPD and tap into a lot of latent distrust of the DSM, APA, and psychological establishment in general. Hopefully we'll have a real effect on the way HPPD and drug-induced disorders in general are handled in the new edition of the DSM. At this point David is just working on fundraising. We're hoping to raise 5000$--basically just to keep us alive and with wifi for the period it takes to get the book finished. I'll post a link to the kickstarter donation page as soon as we have it all figured out. But we need your help: To aid in the fundraising, we need audio or video submissions from ordinary people who suffer from HPPD explaining why such a book is necessary. That's where you come in! If you feel like helping, please email your submission (30 seconds or shorter, please) to dvandyke926@gmail.com Thanks everyone! David and I couldn't do the work that we do without your help and support. Devin Van Dyke Assistant to David Kozin
