My name is Alex, I'm a third-year psychology student at University Greenwich (London, UK).
Although I don't have HPPD, I'm very interested in understanding more about it. As such, my final-year research project is a survey investigating individual differences and HPPD.
My research project is under the supervision of Dr. David Luke, a long-standing psychedelic researcher in the UK and author of many books on the subject. Dr. Luke is a senior lecturer at University of Greenwich and honorary senior lecturer at Imperial College London - the home of the bulk of psychedelic research in the UK. I'm really only trying to use his credentials to verify that this research is a serious undertaking, not just to name drop him. I would love to hear from members of this community and hope you can find the time to have a look at my survey linked below
The survey should take between 15-30 minutes to complete depending on your individual history and experiences. Your response will help deepen the understanding of potential differences amongst sufferers of Hallucinogen Persisting Perception Disorder. All submissions are anonymous (identifiable only through your unique personal code) and data will be stored on a password protected device. The research has been ethically approved by the Departmental Research Ethics Committee for Psychology, University of Greenwich, UK.
Many thanks if you have the time to spend helping me out.

Hi there. I've had HPPD since I was about 19... so going on 16 years now. I won't get into all the details but what I'm wondering is if anyone has resolved, or read about someone who resolved their Blue Field Entoptic Phenomenon (BFEP)? This is probably one of my most annoying symptoms and is prevalent on any large bright surface. Central vision and peripheral.
Any feedback would be much appreciated.
Hello my friends,
I'm writing an article for The Independent about HPPD. I'd like to talk first-hand with sufferers of the disorder and document their stories. This article will spread awareness about the risks of psychedelic drug-taking and show what can go wrong.
If you're interested in having a short chat or sending a summary of your experience with HPPD, then please email me at email@example.com. You can be anonymous on request, don't worry.
I started taking Clonazepam in a really small dose (0,2mg per day) 3 days ago, and yesterday evening I started getting possitive palinopsia and hard afterimages.
Is it possible that Clonazepam induced me this?
My psychiatrist prescribed it to me for Sertraline and Lorazepam withadrawl, for not getting too much abstinence (I am currently on Sertraline 50mg and Lorazepam 0,5mg and going down every week step by step)
During the last 3 months my symptoms increased a lot and I still thinking it’s because Sertraline. I’ve been taking Sertraline 100mg for 3 years now, same with Lorazepam 1g, every day during 3 years.
I talked to my med and he wants to take me off the Sertraline and change Lorazepam for Clonazepam some weeks / months. I am super afraid of withadrawl and also of still using benzodiazepines. My symptoms nowadays are: Severe VS, severe ghosting and palinopsia with afterimages, photophobia, photopsias, nyctalopia, flashes, color problems, apparent movement in objects, kind of bugs in vision, and really mild shaking vision (just on my periphery).
What I can do? Please I need help because my symptoms are so severe nowadays and I don’t want to get them worse, actually I would like they come back at least to last year were they weren’t so noticeable.
I get intrusive thoughts everyday and I need help. I’m 21 years old.
