Psychedelics, Personality and Political Perspectives.

Abstract: The psychedelic experience (including psychedelic-induced ego dissolution) can effect lasting change in a person’s attitudes and beliefs. Here, we aimed to investigate the association between naturalistic psychedelic use and personality, political perspectives, and nature relatedness using an anonymous internet survey. Participants (N = 893) provided information about their naturalistic psychedelic, cocaine, and alcohol use, and answered questions relating to personality traits of openness and conscientiousness (Ten-Item Personality Inventory), nature relatedness (Nature-Relatedness Scale), and political attitudes (one-item liberalism-conservatism measure and five-item libertarian-authoritarian measure). Participants also rated the degree of ego dissolution experienced during their “most intense” recalled psychedelic experience (Ego-Dissolution Inventory). Multivariate linear regression analysis indicated that lifetime psychedelic use (but not lifetime cocaine use or weekly alcohol consumption) po...

Nourishing the Spirit: Exploratory Research on Ayahuasca Experiences along the Continuum of Recovery from Eating Disorders

Abstract: Eating disorders (EDs) are serious health conditions that are among the most difficult to treat. Innovative treatments are needed and modalities from across cultures must be considered. Ayahuasca is a psychoactive plant-based tea originally used by Amazonian indigenous groups. A growing body of research points to its promise in the healing of various mental health issues. This study explored the potential therapeutic value of ayahuasca in the context of EDs, including the perceived impact of the preparatory diet and the ayahuasca purge. Sixteen individuals previously diagnosed with an ED participated in a semi-structured interview relating to their experiences with ceremonial ayahuasca drinking. Interviews were analyzed using thematic analysis. Themes presented relate to the reduction or cessation of ED and mental health symptoms, shifts in body perception, and the importance of a ceremonial setting and after-care. For some, the preparatory diet resulted in familiar patterns of concern; however, none felt triggered by the purge in ayahuasca. Ceremonial ayahuasca drinking shows promise in the healing of EDs and warrants further research.

Something New about Something Old: A 10-Year Follow-Up on Classical and New Psychoactive Tryptamines and Results of Analysis.

Abstract: New psychoactive tryptamines may be a public health risk since they intend to mimic the hallucinogenic effects of regulated psychoactive drugs Few studies describe uses and clinical effects of unregulated new psychoactive tryptamines This study aims (1) to explore the presence of tryptamines classified as NPS among the substances delivered for analysis to a harm-reduction organization; (2) to describe the substances found in the samples after analysis; and (3) to compare analytical results of regulated vs non-regulated tryptamines Samples delivered and analyzed by gas chromatography-mass spectrometry from 2006 to 2015 were included A descriptive study of results was conducted From 25,296 samples that were delivered, 436 were tryptamines; from these 232 (5321%) were non-regulated The most delivered non-regulated tryptamine was 4-AcO-DMT A search of the PubMed database in July 2016 revealed that no studies in humans have ever been carried out with 4-AcO-DMT Unregulated tryptamines likely c

Effects of the Natural β-Carboline Alkaloid Harmine, a Main Constituent of Ayahuasca, in Memory and in the Hippocampus: A Systematic Literature Review of Preclinical Studies.

Abstract: Harmine is a natural β-carboline alkaloid found in several botanical species, such as the Banisteriopsis caapi vine used in the preparation of the hallucinogenic beverage ayahuasca and the seeds of Syrian rue (Peganum harmala). Preclinical studies suggest that harmine may have neuroprotective and cognitive-enhancing effects, and retrospective/observational investigations of the mental health of long-term ayahuasca users suggest that prolonged use of this harmine-rich hallucinogen is associated with better neuropsychological functioning. Thus, in order to better investigate these possibilities, we performed a systematic literature review of preclinical studies analyzing the effects of harmine on hippocampal neurons and in memory-related behavioral tasks in animal models. We found two studies involving hippocampal cell cultures and nine studies using animal models. Harmine administration was associated with neuroprotective effects such as reduced excitotoxicity, inflammation, and oxidative stress, and increased brain-derived neurotrophic factor (BDNF) levels. Harmine also improved memory/learning in several animal models. These effects seem be mediated by monoamine oxidase or acetylcholinesterase inhibition, upregulation of glutamate transporters, decreases in reactive oxygen species, increases in neurotrophic factors, and anti-inflammatory effects. The neuroprotective and cognitive-enhancing effects of harmine should be further investigated in both preclinical and human studies.

Psilocybin-Assisted Therapy: A Review of a Novel Treatment for Psychiatric Disorders

Abstract: 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 reviewed the current literature to investigate the efficacy and safety of psilocybin-assisted therapy for the treatment of psychiatric disorders. There were seven clinical trials that investigated psilocybin-assisted therapy as a treatment for psychiatric disorders related to anxiety, depression, and substance use. All trials demonstrated reductions in psychiatric rating scale scores or increased response and remission rates. There were large effect sizes related to improved depression and anxiety symptoms. Psilocybin may also potentially reduce alcohol or tobacco use and increase abstinence rates in addiction, but the benefits of these two trials were less clear due to open-label study designs without statistical analysis. Psilocybin-assisted therapy efficacy and safety appear promising, but more robust clinical trials will be required to support FDA approval and identify the potential role in clinical psychiatry.

Patterns of HIV Risks and Related Factors among People Who Inject Drugs in Kermanshah, Iran: A Latent Class Analysis

Abstract: The objective of this study was to explore patterns of drug use and sexual risk behaviors among people who inject drugs (PWID) in Iran. We surveyed 500 PWID in Kermanshah concerning demographic characteristics, sexual risk behaviors, and drug-related risk behaviors in the month prior to study. We used latent class analysis (LCA) to establish a baseline model of risk profiles and to identify the optimal number of latent classes, and we used ordinal regression to identify factors associated with class membership. Three classes of multiple HIV risk were identified. The probability of membership in the high-risk class was 0.33, compared to 0.26 and 0.40 for the low- and moderate-risk classes, respectively. Compared to members in the lowest-risk class (reference group), the highest-risk class members had higher odds of being homeless (OR = 4.5, CI: 1.44-8.22; p = 0.001) in the past 12 months. Members of the high-risk class had lower odds of regularly visiting a needle and syringe exchange program as compared to the lowest-risk class members (AOR = 0.42, CI: 0.2-0.81; p = 0.01). Findings show the sexual and drug-related HIV risk clusters among PWID in Iran, and emphasize the importance of developing targeted prevention and harm reduction programs for all domains of risk behaviors, both sexual and drug use related.

Body Image and Eating Disorders are Common among Professional and Amateur Athletes Using Performance and Image Enhancing Drugs: A Cross-Sectional Study.

Abstract: The use of performance and image enhancing drugs (PIEDs) is not uncommon in athletes and appears to be associated with several psychopathological disorders of unclear prevalence. In this multicenter, cross-sectional study, we aimed to evaluate the prevalence of body image disorders (BIDs) and eating disorders (EDs) in PIED-using athletes vs. PIED nonusers. We enrolled 84 consecutive professional and amateur athletes training in sport centers in Italy, who underwent semi-structured interviews (SCID-I, SCID-II) and completed the Body Image Concern Inventory (BICI) and the Sick, Control, One, Fat, Food Eating Disorder Screening Test (SCOFF). PIEDs were searched for in participants' blood, urine, and hair. Of these, 18 (21.4%) used PIEDs, the most common being anabolic androgenic steroids, amphetamine-like substances, coffee and caffeine derivatives, synthetic cathinones, and ephedrine. PIED users and nonusers did not differ in socio-demographic characteristics, but differed in clinical and psychopathological features, with PIED users being characterized by higher physical activity levels, higher daily coffee and psychotropic medication use (e.g., benzodiazepines), more SCID diagnoses of psychiatric disorders, especially substance use disorder, body dysmorphic disorder (BDD), EDs, and general anxiety disorder, higher BICI scores (indicating higher risk of BDD), and higher SCOFF scores (suggesting higher risks for BIDs and EDs).

Seeking Safety Group Therapy for Co-Occurring Substance Use Disorder and PTSD among Transgender Women Living with HIV: A Pilot Study

Abstract: Transgender women living with HIV experience high rates of substance use, violence, and post-traumatic stress disorder (PTSD) Seeking Safety is a manualized, present-focused, cognitive-behavioral therapy program designed to address co-occurring substance use and PTSD Seeking Safety has evidence of efficacy in a variety of populations but had not been evaluated specifically with people living with HIV or transgender women We pilot-tested a 12-session Seeking Safety program with a group of transgender women living with HIV who reported substance use and a history of violence Seven transgender women living with HIV were recruited from two HIV primary care clinics in San Francisco and completed pre- and post-intervention assessments Participants attended an average of 8 of the 12 sessions Mean scores for all three outcome measures improved: PTSD symptom scores declined 175%, alcoholism screening scores declined 239%, and drug abuse screening scores declined 688%, on average Despite the small sample, this pilot study showed Seeking Safety to be a promising intervention among transgender women living with HIV The findings are encouraging and justify larger studies of Seeking Safety among transgender women and other people living with HIV who experience high rates of substance use and PTSD

Relationships between a Dissociative Subtype of PTSD and Clinical Characteristics in Patients with Substance Use Disorders.

Abstract: The increasing support for a dissociative subtype of post-traumatic stress disorder (PTSD-D) has led to its inclusion in DSM-5. We examined relationships between PTSD-D and relevant variables in patients with substance use disorders (SUD). The sample comprised N = 459 patients with SUD. The International Diagnostic Checklist and the Posttraumatic Diagnostic Scale were used to diagnose PTSD. In addition, participants completed the Childhood Trauma Questionnaire and the Dissociative Experiences Scale. The course of SUD was assessed by means of the European Addiction Severity Index. One-fourth of participants fulfilled a diagnosis of PTSD (25.3%). Patients with PTSD-D (N = 32, 27.6% of all patients with PTSD) reported significantly more current depressive symptoms, more current suicidal thoughts, more lifetime anxiety/tension, and more suicide attempts. The PTSD-D group also showed a significantly higher need for treatment due to drug problems, higher current use of opiates/analgesics, and a higher number of lifetime drug overdoses. In a regression model, symptoms of depression in the last month and lifetime suicide attempts significantly predicted PTSD-D. These findings suggest that PTSD-D is related to additional psychopathology and to a more severe course of substance-related problems in patients with SUD, indicating that this group also has additional treatment needs.

Loperamide, the "Poor Man's Methadone": Brief Review.

Abstract: Loperamide is widely available as an inexpensive, over-the-counter remedy commonly used for management of diarrhea. Although an opioid, at therapeutic doses it acts primarily on the gastrointestinal tissues; however, larger than recommended amounts facilitate central nervous system (CNS) penetration. Such high doses of loperamide have recently gained popularity among users of opioids to manage withdrawal symptomatology and, less frequently, to achieve psychoactive effects. Chronic loperamide use can result in development of tolerance and, upon abrupt cessation of use, withdrawal. With increasing prevalence of use, side-effects are noted, one particularly being life-threatening cardiac arrhythmias. Users are often not forthcoming and routine drug screens do not detect loperamide, so providers need to be alert to such practices in order to recognize intoxication, be able to screen for use, and facilitate entry into treatment.

Medicalizing the Opioid Epidemic in the U.S. in the Era of Health Care Reform

Abstract: The medicalization of the current opioid epidemic in the era of health care reform and parity, and its possible dismantling, poses many challenges. Between 2002 and 2013, drug overdose rates quadrupled. Parallel to an increase in prescription opioid overdose, heroin overdose deaths are increasing as patients shift to cheaper and more accessible heroin from the prescription opioids which physicians are prescribing less often due to increasing regulatory restrictions, as well as enhanced education and awareness. In many areas, the leading cause of death for young adults is drug overdose. Unlike previous heroin use in the U.S., the nexus of spread is coming primarily out of the medical system, as the line between legal and illicit narcotics has become blurred. The economic and social benefits of bringing the previously excluded addicted population into the mainstream health care system will be substantial and will bring changes in three major areas: mental health and substance abuse services in health plans; parity protection in all insurance plans; substance abuse and mental health services. Long-term implementation of these changes in a medically oriented system will require the development of many new systems and procedures.

Benzodiazepine Dependence among Young Adult Participants in the Club Scene Who Use Drugs.

Abstract: Young adults ages 18–29 report the highest rates of benzodiazepine (BZD) misuse in the United States. The majority of club drug users are also in this age group, and BZD misuse is prevalent among participants in club scenes. This article examines BZD dependence and its correlates among young adult participants in the electronic dance music (EDM) culture in Miami, Florida, who use drugs. Structured interviews were with men and women (N = 356) ages 18 to 29 who reported regular attendance at EDM venues and recent use of both club drugs and BZDs. Prevalences of BZD-related problems were 12.6% for BZD dependence, 21.1% BZD abuse, and 24.2% BZD abuse and/or dependence. In a multivariate logistic regression model, younger age (OR 0.85; 95% CI 0.76, 0.96), severe mental distress (OR 8.30; 95% CI 3.07, 22.49), daily marijuana use (OR 2.10; 95% CI 1.03, 4.27), and heavy opioid use (OR 2.33; 95% CI 1.12, 4.83) were associated with BZD dependence. BZD dependence was higher in this sample than in other popula...

Motivations for Using MDMA (Ecstasy/Molly) among African Americans: Implications for Prevention and Harm-Reduction Programs

Abstract: Despite the growing popularity of MDMA (ecstasy/molly) among African Americans, their motives for using the drug are still largely unknown. The purpose of this study was to identify and describe the most salient motivations for using MDMA among this understudied population. In-depth interviews (n = 15) were conducted with a sample of African American young adults in Southwest Florida between August 2014 and November 2015. The primary motivations for using MDMA included: (1) altering the effects of marijuana and alcohol; (2) lasting longer sexually; (3) enhancing sexual pleasure; and (4) facilitating “freaky” sexual experiences. This is the first study to directly examine MDMA motivations specifically among African American drug users, and findings shed light on why some African Americans use MDMA. A better understanding of why African Americans use this drug should help to inform prevention and harm-reduction efforts. Study findings show the need for health messages that include the potential cons...

Commercial Health Plan Coverage of Selected Treatments for Opioid Use Disorders from 2003 to 2014.

Abstract: Opioid use disorders (OUDs) are receiving significant attention in the U.S. as a public health crisis. Access to treatment for OUDs is essential and was expected to improve following implementation of the federal parity law and the Affordable Care Act. This study examines changes in coverage and management of treatments for OUDs (opioid treatment programs (OTPs) as a covered service benefit, buprenorphine as a pharmacy benefit) before, during, and after parity and ACA implementation. Data are from three rounds of a nationally representative survey conducted with commercial health plans regarding behavioral health services in benefit years 2003, 2010, and 2014. Data were weighted to be representative of health plans’ commercial products in the continental United States (2003 weighted N = 7,469, 83% response rate; 2010 N = 8,431, 89% response rate; and 2014 N = 6,974, 80% response rate). Results showed treatment for OUDs was covered by nearly all health plan products in each year of the survey, but ...

“Is Marijuana Even a Drug?” A Qualitative Study of How Teens View Marijuana Use and Why They Use It

Abstract: This qualitative study examines how youth in the San Francisco Bay Area perceive marijuana and their motives for using or not using marijuana. Current regular users were more likely to perceive marijuana smoking as an enjoyable activity, comparable to a hobby or sport. Current occasional users commonly reported smoking marijuana when it was offered to them, on special occasions, and sometimes as a result of not wanting to be left out. Most former regular users reported quitting marijuana use due to getting into trouble, being ordered into drug treatment and/or being drug tested. Former occasional users mostly reported that they did not like the somatic effects of marijuana and did not feel it enhanced their social interactions or activities. Teens who reported never having used marijuana did so out of concerns for their health. Except for never-users, marijuana was seen as safe to use. Teens mentioned the widespread use of marijuana by people they know and legalization for medical and recreational use as evidence that marijuana is not harmful. The findings suggest that normalization of marijuana use is taking place. Differences in motives for and against marijuana use should be taken into consideration when designing interventions and prevention messages.

Beyond Ketamine and Phencyclidine: Analytically Confirmed Use of Multiple Novel Arylcyclohexylamines

To Study, to Party, or Both? Assessing Risk Factors for Non-Prescribed Stimulant Use among Middle and High School Students

Abstract: This study examines the risk factors predicting non-prescribed stimulant use (NPSU) among adolescents, with an emphasis on whether such factors are reflective of instrumental (e.g., studying) and/or recreational (e.g., partying) drug consumption settings. Using data from Monitoring the Future (2011), we employed a series of logistic regression models to establish predictors of 12-month self-reported Adderall or Ritalin use without a doctor's note among eighth and tenth graders. Whereas studies of college students have found NPSU to correlate with instrumental motives and productivity-related demands, we find no association between NPSU and indicators of academic strain for this younger sample. Rather, we find that the age of onset and current use of alcohol, tobacco, and marijuana are most predictive of NPSU, which are substances generally associated with social and recreational consumption settings. These findings have potential implications for practitioners concerned with mitigating the harms of general prescription drug misuse, as intervention efforts informed by research conducted among college students may not readily apply to younger populations. Drawing from central tenets of developmental and life course criminology, we call for continued inquiry into the broader socialization and developmental processes that influence NPSU and other prescription drug use patterns prior to early adulthood.

Association of OPRD1 Gene Variants with Opioid Dependence in Addicted Male Individuals Undergoing Methadone Treatment in the North of Iran.

Abstract: Genetic association of rs678849 along with neuroimaging and biomarker phenotypes, parallel with the known involvements of the OPRD1 in drug abuse, provided additional support for targeting these receptors as potential therapeutic targets in both neurodegenerative diseases and neuropsychiactric disorders such as Alzheimer’s disease. Samples were selected among 202 opium-addicted participants undergoing methadone treatment and 202 healthy controls. Genomic DNA of all subjects was extracted from whole blood samples through a Salting Out procedure. Four variants (rs678849, 2236857, 2236855, and 760589) were genotyped in the studied subjects using ARMS-PCR. The analysis was performed using SNPalyze and SPSS ver.20 software. According to single locus analysis, rs678849 under dominant model (p < 0.001), rs2236857 under recessive model (p = 0.006), and the two variants, rs2236855 and rs760589 under co-dominant model, showed significant contributions between groups (p = 0.001 and p = 0.009, respectively). ...

Association between Nonmedical Marijuana and Pain Reliever Uses among Individuals Aged 50.

Abstract: Marijuana and pain reliever use for medical and nonmedical purposes has been increasing among older adults. Using the 2012-2013 U.S. National Survey on Alcohol and Related Conditions (NESARC-III), this study examined: (1) the association between past-year nonmedical marijuana and pain reliever use among adults aged 50+ years (N = 14,715); and (2) sociodemographic, health, and pain-related correlates of nonmedical marijuana and/or pain reliever use. The findings show that 3.87% and 3.12%, respectively, used marijuana and pain relievers nonmedically and 14.40% of marijuana users, compared to 2.67% of nonusers, used pain relievers nonmedically. Controlling for sociodemographics, health status, pain interference, and mental and other substance use disorders, marijuana use anduse disorder were significantly associated with nonmedical pain reliever use and opioid use disorder, respectively. Compared to marijuana users (with or without nonmedical use of pain relievers), nonmedical pain reliever users (without marijuana) are older, married, and women. Users of both substances nonmedically are a small group (0.56% of the 50+ age group), but they are at greatest risk of lifetime opioid, alcohol, and nicotine use disorders. Pain interference is a significant correlate of nonmedical pain reliever use. Healthcare providers should assess for the nonmedical use of these medicines/drugs and help older adults receive effective pain treatment.

Levamisole in Illicit Trafficking Cocaine Seized: A One-Year Study.

Abstract: Cocaine use is increasing around the world and its purity is frequently altered through dilution, substitution, contamination, and adulteration. Sugars, talc, starch, and carbonates represent the principal diluents of cocaine, while phenacetin, levamisole, caffeine, and lidocaine are its major adulterants in Europe. Levamisole is used because it is an odorless powder, with physical properties similar to cocaine, and it has reasonable cost and availability, being widely used in veterinary medicine. For this study, we analyzed 88 cocaine samples. The seized cocaine analyzed showed an average purity of 55% and the most frequent adulterants identified were: levamisole (31.8%), caffeine (6.8%), lidocaine (2.3%), acetaminophen (2.3%), and phenacetin (1.1%). Our aim is the study of the presence of levamisole, over other adulterants in seized cocaine samples, due to its recognized human toxicity. The chronic use of levamisole-adulterated cocaine represents a serious public health issue because it may be responsible for side-effects such as dermal vasculopathy, leukoencephalopathy, leukopenia, agranulocytosis, pulmonary hemorrhage, multiple emboli, and several other effects. Moreover, aminorex can cause idiopathic pulmonary hypertension, presenting another harmful and mostly lethal side-effect from cocaine cut with levamisole. In conclusion, levamisole determination should be performed in routine toxicological analysis in deaths due to cocaine use.

The Blue Lotus Flower (Nymphea caerulea) Resin Used in a New Type of Electronic Cigarette, the Re-Buildable Dripping Atomizer

Abstract: The blue lotus flower (Nymphea caerulea) is an Egyptian water lily containing apomorphine and nuciferine. Apomorphine has been described as a psychoactive alkaloid and is a non-selective dopamine agonist primarily used to treat Parkinson's disease as it stimulates dopamine receptors and improves motor function. Nuciferine is an alkaloid associated with dopamine receptor blockade. Today, blue lotus flower is used as a sleep aid and anxiety reliever. The rebuildable dripping atomizer (RDA) is an electronic cigarette that allows direct application of an e-liquid onto the coil in the atomizer for aerosolization, compared to a typical electronic cigarette where the e-liquid is wicked from a storage vessel to the coil. Our laboratory received a dark-brown resin material from a concerned parent. The resin had been confiscated from an adolescent who had a reported history of marijuana use. The resin was later identified as blue lotus flower (N. caerulea). This resin, together with four commercially available blue lotus products, was analyzed for content. Apomorphine was detected in two samples, and nuciferine was detected in all five samples. The confiscated resin was determined to contain no apomorphine and 4300 ng/g of nuciferine. The nuciferine resin was shown to aerosolize using aRDA electric cigarette.

Early Initiation of Amphetamine-Type Stimulants (ATS) Use Associated with Lowered Cognitive Performance among Individuals with Co-Occurring Opioid and ATS Use Disorders in Malaysia.

Abstract: Amphetamine-type stimulants (ATS) use is increasingly prevalent in Malaysia, including among individuals who also use opioids. We evaluated cognitive functioning profiles among individuals with co-occurring opioid and ATS dependence and their lifetime patterns of drug use. Participants (N = 50) enrolling in a clinical trial of buprenorphine/naloxone treatment with or without atomoxetine completed the Raven’s Standard Progressive Matrices, Rey-Osterrieth Complex Figure Test, Digit Span, Trail Making and Symbol Digit Substitution tasks. Multidimensional scaling and a K-means cluster analyses were conducted to classify participants into lower versus higher cognitive performance groups. Subsequently, analyses of variance procedures were conducted to evaluate between group differences on drug use history and demographics. Two clusters of individuals with distinct profiles of cognitive performance were identified. The age of ATS use initiation, controlling for the overall duration of drug use, was signi...

JWH-122 Consumption Adverse Effects: A Case of Hallucinogen Persisting Perception Disorder Five-Year Follow-Up.

Abstract: Synthetic cannabinoid receptor agonists are a heterogeneous group of psychotropic drugs functionally related to Δ9-tetrahydrocannabinol. These substances, marketed as cannabis substitutes, have been associated with numerous cases of severe intoxication and death across the world. In our article, we describe a case of hallucinogen persisting perception disorder developing in a natural cannabis user after consumption of JWH-122, a naphthoylindole largely used since 2010. Clinical symptomatology persisted for about four years and was alleviated through treatment with clonazepam. Considering that natural cannabis consumption can induce the development of a hallucinogen persisting perception disorder, it is not excluded that, in our patient, symptoms lasted a long time due to cannabis consumption. This article describes the clinical evolution from onset to resolution of all symptoms.

Examination of the Phenomenology of the Ibogaine Treatment Experience: Role of Altered States of Consciousness and Psychedelic Experiences.

Abstract: Psychedelic drugs have historically been used for ritualistic purposes and to help individuals gain insight. Ibogaine, a naturally occurring psychoactive substance, has been reported to have anti-addictive properties that aid in the treatment of substance use disorders. An online survey obtained retrospective data from individuals who used ibogaine in the past. Individuals who used ibogaine tended to describe thematically similar experiences post-treatment. This study adds to the literature by using the 5d-ASC, a psychometrically sound measure of altered states of consciousness (ASCs), to examine the ASCs induced by ibogaine and discusses the demographic characteristics of those who seek ibogaine treatment (N = 27). The study also examined several aspects of ibogaine treatment experience, including reasons for seeking treatment, course of treatment, and treatment outcome. Results indicated a positive correlation between the various dimensions of the ASCs and the outcome (ability to make changes in...

Differences in the Rates of Drug Polyconsumption and Psychiatric Comorbidity among Patients with Cocaine Use Disorders According to the Mental Health Service

Abstract: Cocaine continues to be a worldwide public health concern in Europe. To improve prognosis and intervention, it is necessary to understand the characteristics of the patients who depend on the services where they receive care. The objective is to analyze the differences among patients who use cocaine and between ambulatory and residential resources to better adapt treatment. This is a descriptive, observational study of two populations of cocaine users in treatment: the ambulatory therapeutic community (ATC) and the therapeutic community (TC). The PRISM diagnostic interview was used for both groups. An analysis of both populations indicates a high prevalence of cocaine, heroin, cannabis, sedative, psychostimulant, and hallucinogen use disorders in the TC population compared to the ATC. In alcohol use disorder, differences between both mental health services were not observed. The degree of severity of cocaine use disorders (CUD) is greater in the TC population. The prevalence of psychiatric comorbidity is not statistically significant between the two populations, except for primary psychotic disorders, which are more prevalent in the TC population. This difference in the prevalence of psychotic disorders may be related to the high prevalence of cannabis use disorders in TC patients. Differences in the prevalence of substance use disorders, severity of CUD, and psychiatric comorbidity may limit the efficiency of mental health services involved in substance use disorder therapeutics. These results suggest the need for careful and extensive phenotyping of patients to improve intervention and prognosis in a clinical resource-dependent manner.

Examination of Synthetic Cannabinoid and Cathinone Use among a Drug-Using Offender Sample, 2013-2015.

Abstract: Use of novel psychoactive substances (NPS) such as synthetic cannabinoids (e.g., “Spice,” “Serenity”) and cathinones (e.g., “bath salts”) has proliferated in recent years; however, there is a gap in research examining prevalence among offender samples. This study examined demographics, drug use, mental health characteristics, and criminal histories of NPS users compared to non-NPS users within an offender sample entering drug treatment. Using logistic regression analysis, combined 2013–2015 assessment data were examined (N = 8,791). NPS users offended more often (x = 10.3), were more likely to have experienced homelessness (12.2%), and to have lived in a metro area (59.0%). NPS users reported significantly more past-year drug use, including substances not readily detected by standard urine analysis (e.g., hallucinogens, alcohol, and inhalants). Individuals with higher anxiety symptom counts (OR = 1.07; p < .001) and those who reported drinking to intoxication (OR = 1.30; p < .001) had an increase...

Severity of Withdrawal Symptoms, Plasma Oxytocin Levels, and Treatment Outcome in Heroin Users Undergoing Acute Withdrawal.

Abstract: Pre-clinical studies show that, following chronic opioid exposure, oxytocin neurons exhibit over-excitation upon withdrawal, causing an increase in oxytocin brain and plasma levels. Relevant clinical data on humans are scarce. This study investigates the opioid withdrawal stress effect on oxytocin plasma levels in humans. We evaluated 57 male chronic heroin users in a residential detoxification program. We determined plasma oxytocin levels by ELISA and measured the stress effects of withdrawal using the COWS scale for opioid withdrawal, the VAS scale for craving, and the Hamilton scales for anxiety and depression on the second day of admission. Out of the 57 patients enrolled in the study, 27 completed the 21-day program, while the remaining 30 dropped out prior to completion. Plasma oxytocin levels were significantly higher in those individuals who dropped out than in those who completed the program. Participants who dropped out at some stage scored higher in the COWS, VAS-Craving, and Hamilton-anxiety scales, indicating a higher stress and explaining the higher oxytocin levels. In addition, plasma oxytocin levels correlated positively with the scores achieved in the COWS and Hamilton-anxiety scales. Higher withdrawal stress levels are associated with higher plasma oxytocin levels and early treatment discharge.

Childhood Maltreatment, Emotional Lability, and Alcohol Problems in Young Adults At-Risk for ADHD: Testing Moderation and Moderated Moderation.

Abstract: Childhood maltreatment and alcohol problems are common among young adults with attention-deficit hyperactivity disorder (ADHD). However, little is known about the degree to which maltreatment and alcohol problems are associated; potential pertinent mediating or moderating mechanisms, such as emotional lability; and whether this association varies by sex. We examined, in a sample of adults at risk for ADHD (N = 122, 37% male), the association between childhood maltreatment and alcohol problems, whether emotional lability mediated or moderated this association, and whether either role of emotional lability differed between men and women. Emotional lability moderated the association between emotional neglect and alcohol problems; maltreatment increased risk for alcohol problems for those scoring high tovery high on emotional lability, but not for those with very low-moderate levels. The association between emotional abuse and alcohol problems depended both on emotional lability and sex; emotional abu...

Betel Nut Chewing in Iron Age Vietnam? Detection of Areca catechu Alkaloids in Dental Enamel.

Abstract: The betel quid is one of the most commonly consumed psychoactive substances in the world. By archaeological evidence like the occurrence of areca nuts in archaeological sites, the typical overall reddish-brown staining on prehistoric human teeth or specific artifacts linked with the habit, it is assumed that this tradition reaches back to prehistoric times. Since this kind of evidence is indirect, it is frequently doubted. The present study provides the earliest direct analytical indication of betel nut chewing in human history. A typical stained tooth from an Iron Age skeleton (site Go O Chua in Southern Vietnam, 400–100 BC) was analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and liquid chromatography-high-resolution mass spectrometry (LC-HR-ToF-MS) and the alkaloid arecoline which is specific for Areca catechu L. (Arecaceae) was detected.
