Is there a connection between anxiety and Hallucinogen-persisting perception disorder (HPPD) symptoms? Are there correlations between HPPD symptom clusters with past and current substance use (nicotine, alcohol, psychedelics, etc.)?
Reddit community r/HPPD was formed to raise awareness, encourage the study and research of hallucinogen-persisting perception disorder (HPPD), and support and inform those with or without HPPD. This study is the group's first observational study investigating the connection between anxiety and symptoms of HPPD.
HPPD or Hallucinogen (Induced) Persisting Perception Disorder (HIPPD) is an understudied disorder with a complex and unpredictable nature. It has overlapping psychiatric, psychological, and neurological symptoms that have been reported by a subset of people who have taken psychedelics. Most psychedelics are implicated, but some more than others: LSD, psilocybin, ayahuasca, 2-CB, ibogaine, etc., and also related (but not classically psychedelic) drugs like MDMA, cannabis, dextromethorphan (DXM), datura, ketamine, salvia, and diphenhydramine (DPH).
Sufferers report an alteration of everyday perception including conditions like: Visual Snow Syndrome (VSS), migraine with aura, manic episodes, epilepsy, anxiety disorders and brain injuries.
One of the concerns raised by the subreddit's moderator, Sophia Alcala, as observed from discussions within the community, are reports of anxiety by many of its members. This issue informed the research focus of assessing associations between anxiety severity and the severity of HPPD symptoms.
If you are experiencing or have experienced HPPD then we (r/HPPD, Sophia Alcala and Quantified Citizen) invite you to join this study that may inform future clinical trials and therapies for this condition.
The r/HPPD subreddit is the largest and fastest growing HPPD community to date. This community was formed to raise awareness, encourage the study and research of HPPD, but most importantly support and inform those with or without HPPD.
Sophia Alcala is a 21 year old trans woman, moderator for the subreddit r/HPPD, student of psychology at Southwestern Community College, and facilitator for support groups under SMART Recovery. Her future plans include conducting more research on HPPD and helping those suffering from HPPD.

Declaration of Consent
I have read the written study information.
I have been informed that my anonymous study data can be shared in the future with other researchers in the spirit of open science.
I am aware that my participation is voluntary and that I have the right to withdraw my consent and leave the study at any time without having to give a reason. No new data will be collected at this point.
I have been notified that the data that has already been collected will still be used in the study and cannot be deleted as it will have already been anonymized, encrypted, and saved to the servers.
The researcher has had no influence at all on my choice to participate in this study.
All information obtained during the study will be entirely anonymous. All digital data collection will be self-administered. You will get a unique, randomly generated username and your identity will remain anonymous. Please write down this username and keep it in a secure location. You will need it to login into the app should you lose your phone as well as to access your individual data summary and aggregated data. If for any reason you no longer have access to your QC account, and you do not remember your username, QC will not be able to regenerate your account.
You will never be asked to provide your real name, address, or date of birth. Averaged group data may be published or publicly presented, but it will not be possible to identify individual participants from this data. The Quantified Citizen app will not have access to any of your personal identifying information. Quantified Citizen will only access IP addresses from server logs for security and quality control and will delete them every 48 hours to limit indirect identifiers. Only authorized QC staff can access server logs based on their role and a need-to-know basis in order to fulfill their duties. IP addresses are not included in the data that will be analyzed in this study.
All of the data you enter into the Quantified Citizen app will be encrypted and stored in perpetuity on servers located in Canada. Anonymous data will be accessible to all researchers involved with this study. The data may be accessible to other researchers in the future. Any data you have previously entered into the app regarding the microdosing study will be used in addition to any data you enter in the future.
