#1
Piera Talin, Emilia Sanabria
BACKGROUND: A range of studies has demonstrated the efficacy of the psychoactive Amazonian brew ayahuasca in addressing substance addiction. These have revealed that physiological and psychological mechanisms are deeply enmeshed. This article focuses on how interactive ritual contexts support the healing effort. The study of psychedelic-assisted treatments for addiction has much to gain from ethnographic analyses of healing experiences within the particular ecologies of use and care, where these interventions are rendered efficacious...

Multiple factors, including marijuana decriminalization/legalization, tobacco endgame discourse, and alcohol industry pressures, suggest that the retail regulatory environment for psychoactive or addictive substances is a dynamic one in which new options may be considered. In most countries, the regulation of tobacco, marijuana, and alcohol is neither coherent, nor integrated, nor proportional to the potential harms caused by these substances. We review the possible consequences of restricting tobacco sales to outlets run by government-operated alcohol retail monopolies, as well as the likely obstacles to such a policy...

Benzydamine (BZY) is a non-steroidal anti-inflammatory drug used for the topical treatment of inflammations of the oral and vaginal mucosae. Virtually nothing is known about the central pharmacological actions of BZY. Yet there are reports of voluntary systemic overdosage of BZY in drug addicts, resulting in a euphoric, hallucinatory state. In the present study, we investigated the reinforcing properties of BZY in a rat self-administration paradigm. We found that BZY has a powerful reinforcing effect and that this effect is greatly facilitated in animals that already had substance experience, having previously self-administered heroin and cocaine, indicating cross sensitization between BZY and other common drugs of abuse...

REVIEW
L-S Camilla d'Angelo, George Savulich, Barbara J Sahakian
Today there is continued, and in some cases growing, availability of psychoactive substances, including treatments for mental health disorders such as cognitive enhancers, which can enhance or restore brain function, but also 'recreational' drugs such as novel psychoactive substances (NPS). The use of psychoactive drugs has both benefits and risks: whilst new drugs to treat cognitive symptoms in neuropsychiatric or neurodegenerative disorders could have great benefits for many patient groups, the increasing ease of accessibility to recreational NPS and the increasing lifestyle use of cognitive enhancers by healthy people means that the effective management of psychoactive substances will be an issue of increasing importance...

Caffeine is the most popular psychoactive drug consumed in the world for improving alertness and enhancing wakefulness. However, caffeine consumption beyond limits can result in lot of physiological complications in human beings. In this work, we report a novel detection scheme for caffeine integrating nanohybrid membranes of reduced graphene oxide (rGO) in chitosan modified silica sol gel (rGO: chitosan: silica sol gel) with fiber optic surface plasmon resonance. The chemically synthesized nanohybrid membrane forming the sensing route has been dip coated over silver coated unclad central portion of an optical fiber...

What is the level of consciousness of the psychedelic state? Empirically, measures of neural signal diversity such as entropy and Lempel-Ziv (LZ) complexity score higher for wakeful rest than for states with lower conscious level like propofol-induced anesthesia. Here we compute these measures for spontaneous magnetoencephalographic (MEG) signals from humans during altered states of consciousness induced by three psychedelic substances: psilocybin, ketamine and LSD. For all three, we find reliably higher spontaneous signal diversity, even when controlling for spectral changes...

INTRODUCTION AND AIMS: New psychoactive substances (NPS) have hedonic effects that may lead to dependence. Headshops selling NPS increased in number in Ireland from late 2009. Legislation was enacted in May and August of 2010 that caused their closure. It is unknown whether such events impact the rate of NPS use disorders. DESIGNS AND METHODS: We conducted a population-based study using the Irish national database of episodes of addiction treatment between 2009 and 2012...

BACKGROUND: Prescription opioid abuse and misuse is a serious and growing public health issue. While the most common form of abuse is swallowing intact tablets/capsules, some abusers manipulate, or tamper with, these medications by altering the dosage form to allow for non-oral routes of administration (e.g., injection, inhalation) in order to achieve more rapid or enhanced psychoactive effects. Because administration of opioids via non-oral routes results in greater systemic availability and more rapid central nervous system penetration, we hypothesized that death and major medical outcomes occur more frequently with non-oral routes compared to oral route alone...

Synthetic Cannabinoids (SC) are the widest and most diffused class of Novel Psychoactive Substances. SC are chemically heterogeneous and structurally dissimilar from delta-9-tetrahydrocannabinol, being full agonists of the endocannabinoid system receptors CB1 and CB2. Desired effects include euphoria, talkativeness, feelings of joy and laughter, relaxation. With respect to cannabis, SC intake may also be associated with quicker arise of the effects, shorter duration of action, and larger levels of hangover...

BACKGROUND: Cannabidiol (CBD) is among the major secondary metabolites of Cannabis devoid of the delta-9-tetra-hydrocannabinol psychoactive effects. It is a resorcinol-based compound with a broad spectrum of potential therapeutic properties, including neuroprotective effects in numerous pathological conditions. CBD neuroprotection is due to its antioxidant and antiinflammatory activi-ties and the modulation of a large number of brain biological targets (receptors, channels) involved in the development and maintenance of neurodegenerative diseases...

Many behavioral and biological effects of a psychoactive drug often undergo time-dependent change following even one single drug exposure. The present study examined whether one or two exposures of haloperidol, olanzapine or clozapine would also induce a time-dependent change in their behavioral effects in adolescent rats and whether such a change vary between sexes. Adolescent Sprague-Dawley rats (<40days old) were first treated with one single injection of haloperidol (0.05 and 0.1mg/kg, sc), clozapine (10...

This commentary is to inform clinicians challenged with an increase in people seeking treatment for Substance Use Disorder (SUD), that the ninety percent revolving door, is, in part, due to post-withdrawal, untreated neurotoxicity. This impairment attenuates neurotransmitter signaling and compromises resting state functional connectivity, leading to unwanted sequelae including depression, sleep disturbances, sensation seeking, lack of satisfaction and impulsivity. Neuroimaging studies indicate that neurobiological recovery can take years...

To date, whether individuals with mental illness use high energy drinks (HED) to offset their symptoms, or whether their use began after diagnosis or psychoactive drugs were prescribed is unknown. Their degree of knowledge regarding their symptoms, diagnosis, or what strategies they have used to feel better is also undetermined. A search of the literature yielded no studies about these areas or domains. The current article provides background information on caffeine and HED, with or without alcohol, and the use patterns of consumers of mental health services, as well as their attitudes and knowledge...

This chapter begins with a brief review of descriptions and definitions of mystical-type experiences and the historical connection between classic hallucinogens and mystical experiences. The chapter then explores the empirical literature on experiences with classic hallucinogens in which claims about mystical or religious experiences have been made. A psychometrically validated questionnaire is described for the reliable measurement of mystical-type experiences occasioned by classic hallucinogens. Controlled laboratory studies show that under double-blind conditions that provide significant controls for expectancy bias, psilocybin can occasion complete mystical experiences in the majority of people studied...
