Less potent benzos, such as Ativan (lorazepam), aren’t as effective. Other medications may be more appropriate for people with a history of addiction. In an attempt to help health professionals differentiate flashbacks from HPPD, researchers writing in The Israel Journal of Psychiatry and Related Sciences defined two types of HPPD. Additionally, marijuana is the most commonly used drug in the United States, but reports of HPPD among marijuana users are uncommon.
Hallucinogen Persisting Perception Disorder FAQs
This means that a person with HPPD just has visual disturbances, such as seeing blurry patterns, size distortion, and bright circles. The disorder is different from experiencing flashbacks after the effects of hallucinogens wear off. Some people report episodes of HPPD (type 1) as pleasant, like a “free trip” where they get the good feelings of a hallucinogen without taking a drug. But more commonly, episodes of both types cause feelings of distress and anxiety. One hypotheses suggests anxiety may amplify existing visual disturbances and potentially trigger these visual phenomena.
- Although there is no definitive treatment for HPPD, the supposed first-line treatment for HPPD is with alpha-2 adrenergic drugs such as clonidine and benzodiazepines such as alprazolam and clonazepam.
- Flashbacks are common in people with posttraumatic stress disorder (PTSD).
- Most people experience HPPD symptoms as a flashback (a past incidence that recurs vividly in the mind) or a benign re-experiencing of the initial drug-induced experience.
- People may need to try different medications to find the one that works best for controlling symptoms or take more than one medication to get relief.
Brainspotting Therapy: Addiction Treatment and Recovery
Many report that their visual distortions become more pronounced or even emerge during periods of heightened anxiety or stress. Although there’s no cure for the condition, treatment for HPPD can reduce symptoms and help people with the disorder lead fuller lives. FHE Health offers inpatient and outpatient treatment options that can help you or your loved one learn to cope with HPPD disorder.
Some of the most crucial side effects affect the mind, producing perceptual distortions. Individuals experience time- and space-related perceptual distortions. Although any hallucinogen can cause the symptoms, LSD seems to be the main trigger for developing HPPD. Individuals with a history of using hallucinogens are 4.0% to 4.5% more likely to develop HPPD, and there is no connection between the amount of drug consumed and the likelihood of HPPD 6. On the sixth day, the patient stated, “The space-time can weed cause hppd continuum is not constant. I can close my eyes for 45 seconds and open them, and I am in a different location than the one I am at.
Psilocybin and LSD: What I learnt after experiencing ‘psychedelic flashbacks’
The total remission has been reported in a single patient with flashbacks and anxiety treated with 0.25 mg of Clonidine three times a day for two months 59. Lofexidine (0.2–0.8 mg/day) is a sympatholytic centrally acting α2 presynaptic adrenergic agonist that showed similar efficacy in some cases 23,65,66. The number of people affected by HPPD is hard to determine because many individuals who have used hallucinogens might not feel comfortable discussing it with their healthcare providers.
Lifestyle Quizzes
Although it is rare, if you or someone you know is experiencing symptoms of HPPD, it’s important to seek professional help. Additionally, practicing safe habits when using hallucinogens and being aware of pre-existing mental health issues that make you susceptible to unwanted flashbacks can help you make informed decisions. If you start experiencing hallucinations without a clear cause, it’s important to consult a doctor. Any hallucinatory episodes are concerning, especially if they happen frequently.
Studies show LSD (also called acid) is the most common hallucinogenic drug that can cause HPPD. LSD is a lab-made chemical that is in a class of drugs called psychedelics. In its pure state, it’s a white crystalline substance, but you only need a very small amount to feel the effects.
Drugs that Cause HPPD
He also reported intrusive thoughts in his head and believed his symptoms may be related to LSD. His regimen continued from the previous day; however, around that evening, the patient requested Haldol 5 milligrams and Ativan 2 milligrams orally for anxiety and scary visual hallucinations when he closed his eyes. The other most common symptoms experienced by patients were floaters, palinopsia, photophobia, photopsia and nyctalopia. Currently, the DSM-5 does not include visual snow, nyctalopia, photophobia or floaters in their description of HPPD. A revision of the diagnostic criteria to include these symptoms may better reflect the common presentations and guide clinicians in identifying patients presenting with a suggestive history. Most people experience HPPD symptoms as a flashback (a past incidence that recurs vividly in the mind) or a benign re-experiencing of the initial drug-induced experience.

It was then decided to increase his dose of Invega to 6 grams and add 2 milligrams of lorazepam as needed (PRN) and 50 milligrams of trazodone. Later that night, the patient became moderately agitated, and 2 milligrams of lorazepam were administered. On the fourth day, the patient stated, “Objects appear and disappear from my site, and I see shadows” in his peripheral vision. He also said, “I see flashes of green and different colors that are hard to describe.” Due to no improvements in his symptoms, 25 milligrams of lamotrigine were added. On the fifth day, the patient stated, “I see faces, and I am seeing dead philosophers,” naming Alan Watts.

I know everyone says it but many in the west have pushed this narrative that these two in particular, marijuana and mushrooms, are harmless and even good for you, but trust me, you don’t want to live like this. Ego death, “enlightenment”, and what is alcoholism being “open to new experiences” sounds cool until you look into the mirror and a someone you don’t recognize stares back at you. I can’t even explain the full extent of this disorder, in part from the brain fog/sleep deprivation and in part because a lot of this just can’t be explained in words, at least not with my vocabulary. Unlike flashbacks, which involve reliving aspects of a drug trip, HPPD only affects a person’s vision and those with the condition are aware their perception is not normal. I was concerned from the beginning that my issues were connected to the marijuana I smoked. I found an article that lists THC (among other items) as a potential ingredient for VSS.
Health Conditions
- Cases of HPPD have been documented following the use of different substances, indicating that the disorder is not limited to LSD-induced experiences.
- Because HPPD is relatively under-reported and under-researched, we still don’t know a huge deal about HPPD.
- Unlike the immersive flashbacks that some people have after taking drugs, HPPD flashbacks are purely visual.
- Although data is limited, research shows only 4% to 4.5% of people who take hallucinogenic drugs get it.
Currently, no cure for HPPD is effective in the treatment of all individuals who are struggling with the disorder. Medications have been identified as effective in helping some people manage pseudo flashbacks caused by HPPD. Nearly half of the respondents reported taking multiple “precipitating drugs,” about one-fifth said they took only LSD, roughly 13% took only psilocybin mushrooms, and 5.5% listed only cannabis. The average age of the survey’s respondents was 28, and more than 8 in 10 identified themselves as white — about the same proportion as were male. Locke and other researchers from Harvard, Columbia and Johns Hopkins universities and the New York State Psychiatric Institute conducted an online survey of more than 650 people who self-identified as having experienced HPPD symptoms.
