Hallucinogen Persisting Perception Disorder (HPPD) is a serious and complex condition that deserves more attention in discussions about substance use. It involves persistent perceptual disturbances that continue long after the use of certain psychoactive substances, particularly hallucinogens like LSD and psilocybin. This disorder is not just rare—it significantly affects the lives of those who experience it, leading to distress, disrupted daily functioning, and a significant decline in quality of life.
What Is HPPD?
HPPD occurs when individuals re-experience perceptual symptoms they first encountered during drug use. These are not ordinary hallucinations but rather “pseudo-hallucinations,” which means the affected person is fully aware that these perceptions are not real. Symptoms commonly include visual disturbances like halos around lights, trailing images, or patterns that linger in one’s vision.
This condition often follows the use of classic psychedelics, but it’s not exclusive to them. Other substances, including MDMA, ketamine, and even cannabinoids, have also been linked to HPPD in some cases. Alarmingly, there have been instances of symptoms appearing after non-hallucinogenic substances, such as amphetamines or certain prescription medications. This broad connection to various substances raises significant concerns.
Who Does It Affect?
The prevalence of HPPD is difficult to pin down, but existing studies offer worrying insights. Research suggests that around 4.2% of psychedelic users may experience HPPD, with most affected individuals being young, typically in their early twenties. The disorder’s elusiveness is further compounded by its overlap with other medical and psychological conditions, making proper diagnosis a complex task.
It’s worth noting that symptoms can persist for an extended time, making the long-term effects on cognitive and psychological health a pressing issue. The persistence of visual disturbances can itself impact tasks requiring focus and visual processing, further interfering with everyday life.
The Neuropsychological Impact of HPPD
HPPD is not only a matter of distorted perception—it may also carry cognitive implications. Studies exploring its effects on brain function have revealed potential deficits, particularly in visual-spatial memory, executive functioning, and cognitive flexibility. For instance, difficulties were observed in tasks that required visual recall or problem-solving under changing rules and conditions.
While formal statistical analyses have yet to establish significant group differences, individual cases frequently highlight below-average performance in key cognitive areas. This suggests that the effects of HPPD could be more pronounced than larger group studies are currently capable of capturing with small sample sizes.
A Warning for Substance Use
One of the most concerning aspects of HPPD is its unpredictable nature. Not everyone who uses hallucinogens will experience HPPD, but for those who do, the consequences can be lasting and life-altering. Some individuals developed the condition after just one instance of using psychedelics. This unpredictability underlines the significant risks of deliberate substance use—risks that often go unspoken in settings that romanticise or downplay the dangers of psychoactive substances.
Even beyond the physical and mental toll on functionality, substance use of this kind comes with a range of unknowns. Substances used recreationally may vary in purity, dose, and quality, which only heightens the danger.
Moving Forward with Knowledge
Understanding HPPD gives us insight into how harmful hallucinogens and other psychoactive substances can be. When perceptual disturbances interfere with basic daily actions and cognitive functions, it becomes clear that the risks heavily outweigh the supposed “benefits” often touted about psychedelics. While some argue for their controlled use, the evidence strongly suggests that the unpredictable consequences extend far beyond what anyone anticipates.
This condition serves as a stark reminder that no psychoactive substance is truly “safe.” For those considering hallucinogens, it’s crucial to fully appreciate the possibility of severe, lasting consequences like HPPD. The more people know about these risks, the better chance we have to prevent unnecessary suffering. Living without drugs is the best way to stay healthy and keep a clear mind. (Source: Nature)

The resurgence of psychedelics in the United States has reignited fierce debates about their safety, efficacy, and the ethical concerns surrounding their use in mental health treatment. Once dismissed as dangerous hallucinogens associated with counterculture movements, substances like MDMA and psilocybin are now being promoted as potential therapies for mental health disorders. But despite the rising enthusiasm, serious risks and controversies overshadow the movement’s credibility.
Recent developments have exposed significant flaws in the drive to legitimise psychedelics as a medical treatment. Leading the charge has been the Multidisciplinary Association for Psychedelic Studies (MAPS), founded by Rick Doblin. For years, MAPS championed MDMA, also known as “ecstasy,” as a treatment for post-traumatic stress disorder (PTSD), claiming it could help trauma survivors where traditional therapies had failed. However, these bold claims met resistance in August when the US Food and Drug Administration (FDA) rejected MAPS’s application to approve MDMA for PTSD treatment. The FDA cited unresolved safety concerns and demanded more rigorous research—raising alarm bells about potential harm to vulnerable patients.
Among the issues flagged was the problem of “functional unblinding” in clinical trials. Participants who took MDMA often recognised its effects compared to those given a placebo, potentially biasing the results. Critics argue that such methodological weaknesses undermine the reliability of the findings, making it difficult to separate genuine therapeutic benefits from placebo effects. Additionally, reports of trial participants suffering adverse side effects, including increased suicidal thoughts, cast further doubt on the safety of MDMA in a clinical context.
The lack of robust regulation within the psychedelic movement has also come under fire. Allegations of misconduct during therapy sessions, including inappropriate behaviours by therapists, have been particularly troubling. These incidents suggest that in the rush to advocate psychedelics, the movement has overlooked essential safeguards. Ethical practices have been questioned as some researchers and therapists appear more aligned with the movement’s countercultural roots than with professional medical standards.
From a scientific standpoint, the evidence supporting the use of psychedelics remains alarmingly weak. A Cochrane Review, known for its rigorous analysis of clinical research, assessed psychedelic studies and rated the quality of evidence as “low to very low.” Serious adverse events, including hospitalisations and even fatalities, have been documented in individuals with pre-existing mental health conditions—the very group these treatments are intended to help. These findings underscore the need for extreme caution when considering psychedelics as an alternative to established therapies.
The cultural aspect of the movement further complicates its acceptance within mainstream medicine. Psychedelics are often promoted in a utopian, almost evangelical manner, with supporters touting them as groundbreaking solutions to mental health challenges. However, this fervour risks undermining the scientific objectivity required to evaluate such treatments. For critics, the movement’s idealistic approach appears reckless, prioritising ideology over patient safety and scientific integrity.
The FDA’s rejection of MDMA has prompted some within the movement to re-evaluate their approach. Both Rick Doblin and Lykos Therapeutics’ CEO have stepped down, signalling efforts to professionalise the field and align it more closely with the standards of pharmaceutical regulation. Despite this, the question remains whether the psychedelic industry can overcome its legacy of countercultural enthusiasm and deliver on its promises in a safe, evidence-based manner.
Ultimately, the psychedelic movement’s push for medical legitimacy presents a stark warning about the dangers of rushing experimental treatments into practice. Psychedelics, if mishandled, could not only harm vulnerable individuals but also undermine trust in scientific and psychiatric advances. Until rigorous trials and clear ethical boundaries are established, these substances remain a highly risky proposition, raising more concerns than they answer in the complex landscape of mental health care.

Recent developments in psychedelic research have brought to light significant concerns regarding the integrity and safety of studies focused on these substances. Once hailed as a potential breakthrough in mental health treatment, psychedelics are now facing scrutiny due to issues surrounding research practices and the portrayal of their efficacy.
Scientific Integrity Under Scrutiny
The allure of psychedelics as a promising treatment for mental health conditions like depression and PTSD has sparked widespread interest and investment. However, recent reports suggest that the enthusiasm for these substances may have overshadowed the rigour required in scientific research. Studies often suffer from small sample sizes and lack of proper blinding, which undermines the reliability of their findings. Additionally, the influence of researchers’ personal beliefs has been noted, potentially skewing results and leading to the underreporting of adverse side effects. As noted by The New York Times, “The F.D.A.’s rejection signals greater uncertainty for the future of psychedelic medicine. And it will take more than just additional clinical trials for advocates to get back on track — it might require changing the culture of the research community from within”.
Ethical Concerns and Public Perception
The portrayal of psychedelics as a safe and effective treatment option has been challenged by recent incidents highlighting the risks associated with their use. Cases of inadequate reporting of negative outcomes, such as increased suicidality in some trial participants, underscore the need for cautious interpretation of the available data. The romanticised view of psychedelics, sometimes driven by prominent figures in the field, risks misleading the public and overshadowing the potential dangers these drugs can pose….

Recent research highlights the surprising similarities between smoking and vaping concerning their impact on DNA, challenging the notion that vaping is a safer alternative to smoking. The study, conducted by researchers at the University of Southern California (USC), provides critical insights into how both habits can lead to harmful genetic changes that may contribute to disease development, including cancer.
Study on DNA Methylation: The study focused on DNA methylation, a process that acts as an on/off switch for genes. Researchers examined the genomes of young adults who were either exclusive smokers, vapers, or neither. Using high-tech gene sequencing on cheek swab samples, the study identified 831 differentially methylated regions (DMRs) in the genomes of vapers and 2,863 in smokers. Remarkably, there was a 46% overlap in DMRs between smokers and vapers, suggesting similar genetic alterations occur in both groups.
Implications for Public Health: The findings have profound implications for public health, especially regarding the regulation of vaping products. “These findings indicate that the changes in DNA methylation observed in vapers may contribute to the development of disease, including cancer,” said Stella Tommasi, the study’s lead author and an associate professor at USC. The research underscores the need to keep vaping products away from young people, who are particularly vulnerable to these genetic changes.
The Role of the HIC1 Gene: A significant discovery from the study was the identification of a methylation change in the HIC1 gene, a known tumour suppressor. Changes in this gene have long been associated with lung cancer, indicating that similar carcinogenic processes may occur in young adults who vape. “Electronic cigarettes are not as safe as some people claim, even if the level of most toxicants and carcinogens present in e-liquid and vapour is generally much lower than that found in cigarette smoke,” Tommasi noted. This finding could significantly boost research efforts into understanding the health risks of vaping.
Comparison Between Smokers and Vapers: The study provides a detailed comparison of the genetic impacts of smoking and vaping. While smoking has a more extensive array of identified DMRs, the genetic overlap with vaping suggests that both practices can lead to similar unhealthy changes in DNA. This overlap challenges the perception that vaping is a harmless alternative, emphasising the need for caution and further research into its long-term health effects.
Potential Health Risks Associated with Vaping: The research highlights that vaping may not be the safe alternative it is often portrayed as, given its potential to cause similar genetic changes associated with smoking-related diseases. The methylation changes observed in both vapers and smokers could drive disease development, raising concerns about the long-term health implications for young users who may be unaware of these risks.
The study’s insights into DNA methylation underline the importance of informed public health strategies to address the risks associated with vaping and smoking. As vaping gains popularity among young adults, understanding its genetic impacts is crucial for shaping effective health policies and prevention programs.
