Psychosis and synthetic cannabinoids.

Psychiatry Research October 2018 Huiqiong Deng, Christopher D. Verrico, Thomas R Kosten et al.

Synthetic cannabinoid (SC) products have gained popularity as abused drugs over the past decade in many countries. The SCs broadly impact psychological state (e.g., mood, suicidal thoughts and psychosis) and physiological functions (e.g., cardiovascular, gastrointestinal and urinary). This review is about the effects of SCs on psychotic symptoms in clinical settings and the potentially relevant...

Made from concentrate? A national web survey assessing dab use in the United States.

Drug and Alcohol Dependence September 1, 2018 Kelly A. Sagar, Ashley M. Lambros, Mary Kathryn Dahlgren et al.

Cannabis concentrates, including dabs, contain extremely high levels of Δ9-tetrahydrocannabinol (THC). Although these products appear to be gaining popularity among recreational cannabis consumers, little data exists regarding concentrate use in the US. We conducted a national web-based survey to examine patterns of concentrate use, specifically dabbing. 4077 respondents completed a survey...

Analysis of the Uptake, Metabolism, and Behavioral Effects of Cannabinoids on Zebrafish Larvae.

Zebrafish August 2018 John C Achenbach, Jessica Hill, Joseph P M Hui et al.

The Cannabis sativa plant contains numerous phytocannabinoids and terpenes with known or potential biological activity. For decades, plant breeders have been breeding the Cannabis plant to control for a desired ratio of the major cannabinoids. A high-throughput in vivo model to understand the relationship between the chemical composition of different strains and their therapeutic potential then...

A Qualitative Study on the Effects of Psychoactive Substance use upon Artistic Creativity.

Substance Use & Misuse July 3, 2018 Fruzsina Iszáj, Bea Ehmann, Mark D Griffiths et al.

Psychoactive substance use has often been claimed to help generate and facilitate the artistic creative process. This study explored the role of artists' substance use in their creative processes and their efforts to balance between enhancement and relaxation. Semistructured interviews concerning the artistic creative process and the role of psychoactive substance use were recorded with 72...

Probing the endocannabinoid system in healthy volunteers: Cannabidiol alters fronto-striatal resting-state connectivity.

European Neuropsychopharmacology July 2018 Oliver Grimm, Martin Löffler, Sandra Kamping et al.

Tetrahydrocannabinol (THC) and Cannabidiol (CBD) are two substances from cannabis sativa that have beenimplicated in the treatment of mental and neurological disorders. We concentrated on a previously validated neuroimaging phenotype, fronto-striatal connectivity across different striatal seeds, because of this loop's relevance to executive functioning, decision making, salience generation and...

Mood Fluctuation and Psychobiological Instability: The Same Core Functions Are Disrupted by Novel Psychoactive Substances and Established Recreational Drugs

Brain Sciences March 13, 2018 Andrew C. Parrott 13 citations

Many novel psychoactive substances (NPS) have entered the recreational drug scene in recent years, yet the problems they cause are similar to those found with established drugs. This article will debate the psychobiological effects of these newer and more traditional substances. It will show how they disrupt the same core psychobiological functions, so damaging well-being in similar ways. Every...

Phytocannabinoids modulate emotional memory processing through interactions with the ventral hippocampus and mesolimbic dopamine system: implications for neuropsychiatric pathology.

Psychopharmacology February 2018 Roger Hudson, Walter J Rushlow, Steven R Laviolette

Growing clinical and preclinical evidence suggests a potential role for the phytocannabinoid cannabidiol (CBD) as a pharmacotherapy for various neuropsychiatric disorders. In contrast, delta-9-tetrahydrocannabinol (THC), the primary psychoactive component in cannabis, is associated with acute and neurodevelopmental propsychotic side effects through its interaction with central cannabinoid type...

Human Drug Discrimination: Elucidating the Neuropharmacology of Commonly Abused Illicit Drugs.

Current Topics in Behavioral Neurosciences 2018 B Levi Bolin, Joseph L Alcorn, Anna R Reynolds et al.

Drug-discrimination procedures empirically evaluate the control that internal drug states have over behavior. They provide a highly selective method to investigate the neuropharmacological underpinnings of the interoceptive effects of drugs in vivo. As a result, drug discrimination has been one of the most widely used assays in the field of behavioral pharmacology. Drug-discrimination...

Self-Experiments with Psychoactive Substances: A Historical Perspective.

Handbook of experimental pharmacology 2018 Torsten Passie, Simon D. Brandt

The purpose of this chapter is to highlight the rich tradition of self-experiments (SEs) with psychoactive substances carried out by scientists and therapists for more than a century. Scientifically inspired controlled SEs dominated until the end of the twentieth century, when ethical requirements minimized controlled SEs and "wild" SEs expanded particularly with the emergence of new...

Pharmacies as potential providers of harm reduction services: A preliminary online survey

Drug Science, Policy and Law 2018 Edward James, Thomas L Robertshaw, Andrew D. Westwell et al. 4 citations

Background Recreational drug use is a major cause of disease, injury, physical and mental impairment and death in developed countries such as the United Kingdom and the United States. Alcohol, tobacco, cannabis, 3,4-methylenedioxymethamphetamine (MDMA) and psilocybe mushrooms are recreational drugs with capacity to cause harm. Cannabis, MDMA and psilocybin have reported therapeutic...
