OBJECTIVE: The harmful use of psychoactive substances represents one of today's largest public health problems. Yet, in spite of its global relevance, current treatment for substance use disorders (SUDs) is still not entirely successful. The purpose of this study was to investigate alternative treatments and conceptions from traditional Amazonian medicine adapted to SUDs. METHODS: We conducted...
BACKGROUND: Cannabis abuse (CA) has been associated with psychopathology, including negative emotionality and higher risk of psychosis, particularly with early age of initiation. However, the mechanisms underlying this association are poorly understood. Because aberrant dopamine signaling is implicated in cannabis-associated psychopathology, we hypothesized that regular CA would be associated...
Objective: Few studies have evaluated moderators of mindfulness-based relapse prevention (MBRP) for substance use disorders (SUDs). We tested whether baseline patterns of scores for SUD symptom severity and depression and anxiety symptoms moderated the efficacy of MBRP. Method: We used a latent class moderation approach with data from a randomized trial of MBRP compared to cognitive–behavioral...
This survey examined perceptions among college students about the potential medicinal benefits of hallucinogenic drugs. Current research and potential benefits include an ability to help anxiety, post-traumatic stress disorder, and addiction with hallucinogen-assisted psychotherapy. We devised and administered a survey on 124 students at two college campuses, one small private college in the...
This article explores how women’s sexual/spiritual lives were transformed with sacred Amazonian plant teachers (i.e. plants believed to have spirits that communicate with humans). The research was guided by the belief that the practice of vegetalismo (a South American healing tradition that uses plant teachers for healing) holds important lessons for guiding women’s sexual/spiritual lives and...
Comorbid post-traumatic stress disorder (PTSD) and substance use disorders (SUD) commonly co-occur and is associated with a more complex clinical presentation with poorer clinical outcomes when compared with either disorder alone, and untreated PTSD can predict relapse to substance abuse. A number of integrated treatment approaches addressing symptoms of both PTSD and SUD concurrently...
Psychedelic drugs, such as lysergic acid diethylamide (LSD), mescaline, and psilocybin, exert profound effects on brain and behavior. After decades of difficulties in studying these compounds, psychedelics are again being tested as potential treatments for intractable biomedical disorders. Preclinical research of psychedelics complements human neuroimaging studies and pilot clinical trials,...
Although therapeutic treatments exist for substance use disorder (SUD), about half of individuals who enter treatment leave early and relapse to substance use. Early dropout from residential treatment places individuals at risk of relapse, and women in SUD residential treatment represent a vulnerable population. Evidence gaps persist for the use of mindfulness-based interventions (MBIs) among...
Objective This report documents the phenomenology of the subjective experiences of 22 patients with substance-related disorders who were involved in a treatment combining cognitive–behavioral therapy and hospital sessions with ibogaine in Brazil. Methods Participants underwent a one-to-one semi-structured interview exploring the subjective effects of ibogaine. We employed interpretative...
This article examines DMT by Jeremy Shaw, a Berlin-based Canadian artist whose oeuvre has investigated altered states. For this 2004 video work, Shaw administered the hallucinogen dimethyltryptamine to a group of friends and videotaped their experiences. I am interested in how Shaw curates the psychedelic session as a performance of the drug’s agency and aesthetic power. A powerful entheogen...
Background: Significant effect of mindfulness based stress reduction (MBSR) therapy has been demonstrated on depression. Although MBSR are effective and highly valued, but all the patients do not shows
Autoscopic phenomenon, a psychic illusionary duplication of one's own self, has been the subject of interest in the literature and science for years. It has been reported in various diseases of the central nervous system but with an unknown mechanism. Hallucinations are a common presentation in alcohol dependence syndrome during delirium tremens and as induced disorder. However, autoscopic...
Although effect of mindfulness based stress reduction (MBSR) are effective and highly valued, but all the patients will not be interested due to extensive time and cost. Brief interventions (e.g., body scans) may be used by individuals, at a lower cost and with little training. Aim: To study the effect of body scan meditation on negative and positive affect in patients with alcohol dependence....
The present study examines the effectiveness of body scan meditation of mindfulness based stress reduction on craving in patient with alcohol dependence. An inpatient of 36year old with diagnosis of alcohol dependence disorder as per ICD-10 DCR criterion was selected purposively, from Central Institute of Psychiatry, Ranchi. Following detoxification subject was evaluated for withdrawal...
Objective: To examine cognitive and affective mechanisms underlying mindfulness-based addiction treatment (MBAT) versus cognitive-behavioral therapy (CBT) and usual care (UC) for smoking cessation. Method: Participants in the parent study from which data were drawn (N = 412; 54.9% female; 48.2% African American, 41.5% non-Latino White, 5.4% Latino, 4.9% other; 57.6% annual income <$30,000) were...
Adolescence is a phase of development during which many physiological and behavioral changes occur, including increased novelty seeking and risk taking. In humans, this is reflected in experimentation with drugs. Research demonstrates that drug use that begins during adolescence is more likely to lead to addiction than drug use that begins later in life. Despite this, relatively little is known...
Despite several studies suggesting the therapeutic use of 5-hydroxytryptamine receptors type 2A (5-HT2A ) agonists in the treatment of substance use disorders, the neurobiological basis accounting for such effects are still unknown. It has been observed that chronic exposure to drugs of abuse produces molecular and cellular adaptations in ventral tegmental area (VTA) neurons, mediated by...
Recent research suggests that functional connectivity changes may be involved in the pathophysiology of psychiatric disorders. Hyperconnectivity in the default mode network has been associated with psychopathology, but psychedelic serotonin agonists like psilocybin may profoundly disrupt these dysfunctional neural network circuits and provide a novel treatment for psychiatric disorders. We have...
Since the late 1980s the psychoactive drug 3,4-methylenedioxymethamphetamine (MDMA) has had a well-known history as the recreationally used drug ecstasy. What is less well known by the public is that MDMA started its life as a therapeutic agent and that in recent years an increasing amount of clinical research has been undertaken to revisit the drug's medical potential. MDMA has unique...
Preliminary studies show psychedelic compounds administered with psychotherapy are potentially effective and durable substance misuse interventions. However, little is known about the association between psychedelic use and substance misuse in the general population. This study investigated the association between psychedelic use and past year opioid use disorders within illicit opioid users....
