LSD

Hallucinogen use predicts reduced recidivism among substance-involved offenders under community corrections supervision

January 2, 2014 / LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / , , , ,

Abstract

Hallucinogen-based interventions may benefit substance use populations, but contemporary data informing the impact of hallucinogens on addictive behavior are scarce. Given that many individuals in the criminal justice system engage in problematic patterns of substance use, hallucinogen treatments also may benefit criminal justice populations. However, the relationship between hallucinogen use and criminal recidivism is unknown. In this longitudinal study, we examined the relationship between naturalistic hallucinogen use and recidivism among individuals under community corrections supervision with a history of substance involvement (n=25,622). We found that hallucinogen use predicted a reduced likelihood of supervision failure (e.g. noncompliance with legal requirements including alcohol and other drug use) while controlling for an array of potential confounding factors (odds ratio (OR)=0.60 (0.46, 0.79)). Our results suggest that hallucinogens may promote alcohol and other drug abstinence and prosocial behavior in a population with high rates of recidivism.

Abstract

Richard Yensen was a research fellow at the Maryland Psychiatric Research Center from 1972 to 1976. He studied psychedelic psychotherapy with Stanislav Grof, M.D. and other senior staff. During this time he treated patients with substance abuse disorders, cancer, neurosis, and other health professionals seeking a training experience. Dr. Yensen did his Ph.D. dissertation on the use of MDA in psychotherapy with neurotic outpatients and conducted his research at the MPRC. Through many years of experience in governmentsanctioned psychedelic research, he has evolved a non-drug shamanistic psychotherapy called Perceptual Affective Therapy. In the 1990’s Richard was co-holder of IND 3250, an investigational new drug permit issued by the U.S. Food and Drug Administration to study LSD and psychotherapy until 2006. He is currently a licensed psychologist in California and director of the Orenda Institute in Vancouver and Cortes Island, British Columbia, Canada and president of the Salvador Roquet Psychosynthesis Association. He has served on the faculties of Harvard Medical School, Johns Hopkins University and the University of Maryland Medical School in Baltimore.

Flashbacks and HPPD: A Clinical-oriented Concise Review.

January 1, 2014 / LSD, Papers, Psychology, Publications / By / , ,

Abstract

A unique characteristic of LSD, LSD-like and substances with hallucinogenic properties is the recurrence of some or all the hallucinogenic symptoms which had appeared during the intoxication after the immediate effects of the substance had worn off. This recurring syndrome, mainly visual, is not clearly understood. The terms Flashback and Hallucinogen Persisting Perception Disorder (HPPD) have been used interchangeably in the professional literature. We have observed at least two different recurrent syndromes, the first Flashback Type we refer to as HPPD I, a generally short-term, non-distressing, benign and reversible state accompanied by a pleasant affect. In contrast, the second HPPD Type we refer to as HPPD II, a generally long-term, distressing, pervasive, either slowly reversible or irreversible, non-benign state accompanied by an unpleasant affect. HPPD I and II appear to be part of a broad spectrum of non-psychopathological and psychopathological states reported by hallucinogen users. HPPD I and II may be clinically characterized by prodromal symptoms, onset, content of visual imagery, precipitators, frequency, duration and intensity of perceptual recurrences, severity, course, differential diagnosis, accompanying mood and affect, insight and remission. Pharmacological therapy with or without preceding or following co-occurring psychiatric disorders have been shown to ameliorate this syndrome. A large variety of medications may be utilized to alleviate this condition, but with differential results suggesting several subtypes. The purpose of this manuscript is to provide a clinical-oriented, comprehensive and concise review to treating psychiatrists.

Serotonergic hyperactivity as a potential factor in developmental, acquired and drug-induced synesthesia

October 21, 2013 / LSD, Mescaline / Cacti, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications / By /

Abstract

Though synesthesia research has seen a huge growth in recent decades, and tremendous progress has been made in terms of understanding the mechanism and cause of synesthesia, we are still left mostly in the dark when it comes to the mechanistic commonalities (if any) among developmental, acquired and drug-induced synesthesia. We know that many forms of synesthesia involve aberrant structural or functional brain connectivity. Proposed mechanisms include direct projection and disinhibited feedback mechanisms, in which information from two otherwise structurally or functionally separate brain regions mix. We also know that synesthesia sometimes runs in families. However, it is unclear what causes its onset. Studies of psychedelic drugs, such as psilocybin, LSD and mescaline, reveal that exposure to these drugs can induce synesthesia. One neurotransmitter suspected to be central to the perceptual changes is serotonin. Excessive serotonin in the brain may cause many of the characteristics of psychedelic intoxication. Excessive serotonin levels may also play a role in synesthesia acquired after brain injury. In brain injury sudden cell death floods local brain regions with serotonin and glutamate. This neurotransmitter flooding could perhaps result in unusual feature binding. Finally, developmental synesthesia that occurs in individuals with autism may be a result of alterations in the serotonergic system, leading to a blockage of regular gating mechanisms. I conclude on these grounds that one commonality among at least some cases of acquired, developmental and drug-induced synesthesia may be the presence of excessive levels of serotonin, which increases the excitability and connectedness of sensory brain regions.

The induction of synaesthesia with chemical agents: a systematic review

Abstract

Despite the general consensus that synaesthesia emerges at an early developmental stage and is only rarely acquired during adulthood, the transient induction of synaesthesia with chemical agents has been frequently reported in research on different psychoactive substances. Nevertheless, these effects remain poorly understood and have not been systematically incorporated. Here we review the known published studies in which chemical agents were observed to elicit synaesthesia. Across studies there is consistent evidence that serotonin agonists elicit transient experiences of synaesthesia. Despite convergent results across studies, studies investigating the induction of synaesthesia with chemical agents have numerous methodological limitations and little experimental research has been conducted. Cumulatively, these studies implicate the serotonergic system in synaesthesia and have implications for the neurochemical mechanisms underlying this phenomenon but methodological limitations in this research area preclude making firm conclusions regarding whether chemical agents can induce genuine synaesthesia.

Effective interventions in the problematic use of alcohol and other drugs

October 1, 2013 / LSD, Papers, Psychology, Publications, Substance Use Disorder / By / , , , ,

Abstract

OBJECTIVE:
Synthesize and assess the available scientific evidence from the period 2008-2012 on interventions of demonstrated efficacy in the treatment and rehabilitation of adolescents and adults engaged in the problematic use of alcohol and other substances.

METHODS:
A systematic review was undertaken with search and analysis of national and international literature on the subject in Spanish and English in the main international databases: PubMed/MEDLINE, LILACS, Embase, PsycINFO, SciELO, the databases of the York University Centre for Reviews and Dissemination (DARE, ETS Database), the Cochrane Library, and other sources of gray literature. The search criteria included randomized clinical trials and systematic reviews but excluded observational studies, qualitative studies, and articles of poor methodological quality.

RESULTS:
The final sample consisted of 69 studies. The psychosocial interventions shown to be effective were cognitive behavioral therapy, family interventions, self-help interventions using the Internet, couples behavioral therapy, community strengthening and family training, telephone monitoring and support, and integrated therapy for substance abuse disorder with anxiety and depression comorbidity. Pharmacological interventions of demonstrated effectiveness were acamprosate, lysergic acid diethylamide (LSD), and benzodiazepines in problematic alcohol use, as well as maintenance therapy with high-dose opioids.

CONCLUSIONS:
The demonstrated effectiveness of psychosocial and pharmacological interventions is slight but significant. However, strongly multidisciplinary interventions that use a cognitive behavioral approach and the involvement of people close to the consumer, as well as some of the specific pharmacological interventions, have been shown to yield the best results in terms of indicators of abstinence and prevention of relapses.

Self-Medication of LSD and MDMA to Treat Mental Disorders: A Case Series

September 18, 2013 / Anxiety Disorders / PTSD, Depressive Disorders, LSD, MDMA, Papers, Psychology, Publications / By /

Abstract

50 years ago LSD was prescribed to treat a variety of mental illnesses. More recently LSD and MDMA (ecstasy) have become widely used outside medicine as both recreational drugs and by some patients as ‘self-medication’. These brief reports gather together five patients’ experiences using psychedelic drugs to treat their mental disorders. They are discussed in relation to the medical profession’s current growing interest in re-visiting psychedelic drugs as therapeutic treatments in psychiatry. The first case describes the successful self-treatment for depression using LSD, followed by a case in which doctors administered LSD in the 1960s and 1970s to successfully treat a case of obsessive-compulsive disorder (OCD) and chronic fatigue syndrome. The third and fourth cases describe the successful self-treatment of OCD using respectively MDMA and then LSD and the final case describes a self-treatment with LSD to manage Anorexia Nervosa. All the participants describing their use of these drugs give a positive report of self-treatment with minimal adverse effects. They also all support a resumption of more research into the therapeutic use of hallucinogens/psychedelic drugs as potential clinical therapies.

A proposal to evaluate mechanistic efficacy of hallucinogens in addiction treatment

September 1, 2013 / Ayahuasca, DMT, Iboga / Ibogaine, LSD, Mescaline / Cacti, Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / ,

Abstract

Current treatments for addiction are frequently ineffective. Hallucinogenic therapy has been indicated as helpful for a range of substance use disorders, yet this approach remains understudied and publicly unavailable. It is nonetheless a promising treatment, which has significant, long-term beneficial effects with single doses and a profile characterized by general safety, low toxicity, and non-addictiveness. However, pharmacological interventions, such as hallucinogens, should not be offered if the same effects (e.g. psychological insights/mystical experiences) and outcomes (e.g. decreased drug use) could be achieved absent pharmacological intervention. To date, there have been no clinical comparisons of drug-induced altered states with non-drug-induced states for addiction treatment. We propose and then outline a clinical trial to address this gap in knowledge. The proposed design would evaluate abstinence outcomes in a population of prescription opioid abusers after exposure to one of three conditions: a drug-induced altered state using psilocybin, a non-drug-induced altered state via hyperventilation (Holotropic Breathwork), and an active placebo with niacin. The outcomes of such a study would reveal important differences in therapeutic potential by discriminating hallucinogen-dependent effects from those psychological effects resulting from altered states.

Effects of Schedule I drug laws on neuroscience research and treatment innovation

June 12, 2013 / Ayahuasca, DMT, LSD, MDMA, Mescaline / Cacti, Mushrooms / Psilocybin, Neuroscience, Papers, Publications, Salvia / Salvinorin A / By / , ,

Abstract

Many psychoactive drugs are used recreationally, particularly by young people. This use and its perceived dangers have led to many different classes of drugs being banned under national laws and international conventions. Indeed, the possession of cannabis, 3,4‑methylenedioxy‑N‑methylamphetamine (MDMA; also known as ecstasy) and psychedelics is stringently regulated. An important and unfortunate outcome of the controls placed on these and other psychoactive drugs is that they make research into their mechanisms of action and potential therapeutic uses — for example, in depression and post‑traumatic stress disorder — difficult and in many cases almost impossible.

Hallucinogen persisting perception disorder: what do we know after 50 years?

March 1, 2013 / DMT, Ketamine, LSD, MDMA, Mescaline / Cacti, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications, Salvia / Salvinorin A / By / ,

Abstract

‘Flashbacks’ following use of hallucinogenic drugs have been reported for decades; they are recognized in DSM-IV as ‘Hallucinogen Persisting Perception Disorder (Flashbacks)’, or HPPD. We located and analyzed 20 quantitative studies between 1955 and 2001 examining this phenomenon. However, many of these studies were performed before operational criteria for HPPD were published in DSM-III-R, so they are difficult to interpret in the light of current diagnostic criteria. Overall, current knowledge of HPPD remains very limited. In particular (1) the term ‘flashbacks’ is defined in so many ways that it is essentially valueless; (2) most studies provide too little information to judge how many cases could meet DSM-IV criteria for HPPD; and consequently (3) information about risk factors for HPPD, possible etiologic mechanisms, and potential treatment modalities must be interpreted with great caution. At present, HPPD appears to be a genuine but uncommon disorder, sometimes persisting for months or years after hallucinogen use and causing substantial morbidity. It is reported most commonly after illicit LSD use, but less commonly with LSD administered in research or treatment settings, or with use of other types of hallucinogens. There are case reports, but no randomized controlled trials, of successful treatment with neuroleptics, anticonvulsants, benzodiazepines, and clonidine. Although it may be difficult to collect large samples of HPPD cases, further studies are critically needed to augment the meager data presently available regarding the prevalence, etiology, and treatment of HPPD.
