Check out this really good in-depth questionnaire, which asks about what helps, accompanying conditions, patterns of drug use with HPPD, etc.!
Our new survey study of hallucinogen persisting perception disorder (HPPD) experiences is now open. We hope this will help us glean new insights about phenomenology, risk factors, and treatment options for this condition. Please share/RT! hopkinspsychedelic.org/hppds…
"[V]eteran retreat centres like Esalen have traditionally said people should not make major life-decisions for at least two weeks after a spiritual retreat".
The same applies also to self-diagnoses people come to, inc. HPPD. A lot of rabbit-holed false positives come to us

And this has to some extent to be an under-count, because it is subject to survivorship bias. A certain degree of health is required to keep going after a psychedelic crisis, let alone to fill in a survey.

Around 3.7% of a representative sample of the UK population reported symptoms compatible with Visual Snow; estimated prevalence of HPPD in the psychedelic community is 4.2%. HPPD may affect those with pre-existing visual aberrations.

Two new members of the Directory this month. We host specialist professionals from around the world with previous experience and expertise in HPPD: a first for a condition that many people struggled to get diagnosed or adequately treated.

1. @HolBjo: a Norwegian psychologist working in public health care and Psykolyse, a clinic specializing on psychedelic integration therapy.
2. @ThomasKnuijver: an addiction physician who specialises in treating opioid addiction with ibogaine, and has published a case report of ibogaine-induced HPPD!
Check out @EdPrideaux's talk on HPPD to the Psychedelic Society of the Netherlands... Live from an Amsterdam smart shop last month!

#HPPD people!!
I just got word of a research survey from @EdPrideaux and @PerceptionFdn!
This is the most in-depth research questionnaire on HPPD and post-drug visual changes! This is imperative to getting better numbers; understanding the complexeties of HPPD!
#VisualSnow
Curious detail in a paper on Visual Snow Syndrome, of which HPPD has been variously deemed a subtype. Some interpret their 'HPPD' - as with voice-hearing and visions in the traditional psychosis spectrum - as being of mystical origin. The same can apply to VSS!
In 2014, just under 30% between 12-17 believed there was no significant risk from taking LSD 1-2 x a week: a strong increase from 2002 w/out the current 'renaissance'.
What would it be now, ten years on, when they're told the drugs are 'safe', 'non-addictive' and 'healing'?
Interesting piece in The Atlantic from earlier this month on why/how 'neuroplasticity' isn't always a good thing.

@NeuroCalder, @FrancescoScarl9 and @samuelstancl have suggested that HPPD/sustained visual disturbances may be as a result of psychedelic-induced neuroplasticity.

Sorry if we're late to the party, but have people noticed that Mind Medicine Australia's successful TGA submission for MDMA made no mention of any of the findings of Cover Story: Power Trip, or risk of sexual abuse/exploitation?
Please participate! Dr. Henry Abraham estimated that about 1/3 of HPPD patients he saw during his career would develop a psychosis spectrum condition. Yet we still don't know very much about psychedelics relate to psychosis!
