Better social but worse academic premorbid adjustment in cannabis-users psychotic patients across Europe
2016
Background: Several studies report that patients with psychosis who used cannabis have a better cognitive performance than those whodid not (Rabin et al. 2011). In a previous study we found out a higher premorbid IQ, and a better IQ in psychotic patients who smoked cannabis in their lifetime, and our findings were consistent with the idea that this association is due to a better premorbid functioning rather than to an ameliorative effect of cannabis use on cognitive performance (Ferraro et al., 2013). A number of authors have hypothesized that psychotic patients who consume cannabis constitute a differentiated subgroup of patients that have better cognitive and social skills, necessary to e…
Out of time? - Music, consciousness states and neuropharmacological mechanisms of an altered temporality
2009
Drug-induced altered temporality is a well-known effect of cannabis action that is utilised from musicians and music listeners for music appreciation since the early days of jazz. Cannabis has an influence on timing processes at short time scales of hundreds of milliseconds as O’Leary et al (2003) have shown in their tapping studies, proving evidence of an altered cerebellar functioning. This paper will focus on cannabis and its action on timing and aims to discuss selected scientific streams of research on the neurophysiological and neuropharmacological base of timing mechanisms in terms of an social pharmacology of music (Fachner, 2009). The mechanisms behind this altered temporality rema…
THE RELATION OF THE PSYCHOSIS CONTINUUM WITH SCHIZOPHRENIA POLYGENIC RISK SCORE AND CANNABIS USE

Estudio epidemiológico de probabilidades y predictores entre distintos estadios de uso de sustancias y desarrollo de comorbilidad psiquiátrica a nive…
2019
Introducción: Existen diferentes grados de severidad de uso de sustancias incluyendo el consumo, los trastornos por uso de sustancias de distinta severidad, la remisión y la recaída. Adicionalmente, el uso de sustancias puede relacionarse con el desarrollo de comorbilidad psiquiátrica a largo plazo. La mayoría de estudios epidemiológicos que observan las tasas de transición entre distintos niveles de severidad se han realizado en su mayoría utilizando bases de datos clínicos, que no son representativas de la población en general. Eso limita la utilidad de esos estudios para entender estos fenómenos a nivel poblacional y elaborar políticas de salud pública dirigidas a las comunidades. Objeti…
Badania nad potencjalnym wykorzystaniem pluskwiaków różnoskrzydłych (Hemiptera: Heteroptera) w bioindykacji i monitoringu przyrodniczym
2023
This paper presented the results of the studies on true bugs (Hemiptera: Heteroptera) alongside evaluating their potential usefulness in biomonitoring and bioindication. The studies were carried out in May and August of 2017. Three research sites situated at various distances from the full-scale plants (Grupa Azoty Zakłady Azotowe Kędzierzyn SA, Zakłady Chemiczne Petrochemia-Blachownia SA, Zakłady Koksownicze ArcelorMittal Poland Zdzieszowice) and the control area out of reach of the emission of chemical pollutants, i.e. the meadows in the Chrząstowice area of Natura 2000, have been selected for studies. All studied meadows were classified within the Molinio-Arrhenatheretea class. As a resu…
La cultura del cannabis treinta años después... unas reflexiones personales
2005
En la primera parte del articulo se expone una síntesis de lo que fue la "cultura del hachís", que aglutinó a los jipis catalanes a finales de los sesenta, y que el autor estudió a principios de los años ochenta. En el punto siguiente, se sintetizan los principales elementos de la actual "cultura del cannabis" en España, haciendo hincapié en el movimiento social que la sustenta.Y en la discusión posterior se constatan las discontinuidades y continuidades entre ambos momentos históricos. Entre estas últimas, se subraya el ambivalente lugar del cannabis, entre la normalización social y su uso como "pretexto represivo", tanto en el campo de la política como en el de la salud.
Cannabis Use and the Risk for Psychosis and Affective Disorders.
2019
Objective: This review discusses the relationship between cannabis use and psychotic, bipolar, depressive, and anxiety disorders, as well as suicide. It summarizes epidemiological evidence from cross-sectional and long-term prospective studies and considers possible etiological mechanisms. Methods: Systematic reviews and methodologically robust studies in the field (from inception to February 2019) were identified using a comprehensive search of Medline, PsychINFO, and Embase and summarized using a narrative synthesis. Results: Consistent evidence, both from observational and experimental studies, has confirmed the important role of cannabis use in the initiation and persistence of psychoti…
Experiencias psicóticas atenuadas y consumo de cannabis en adolescentes de la población general
2019
El propósito de este estudio fue analizar la relación entre las experiencias psicóticas atenuadas y el consumo de cannabis en una muestra representativa de adolescentes de la población general. Un total de 1,588 estudiantes (M=16,13 años; DT = 1,36), 739 eran hombres (46,5%), pertenecientes a 34 escuelas y 98 aulas, seleccionados mediante muestreo aleatorio estratificado por conglomerados, fueron encuestados. Los instrumentos administrados fueron el Cuestionario de Pródromos de Psicosis-Breve, el Cuestionario de Capacidades y Dificultades, el Cuestionario de Consumo de Sustancias Modificado, el Penn Matrix Reasoning Test (PMRT), la Family Affluence Scale-II y la Escala Oviedo de Infrecuenci…
Schizophrenia polygenic risk score and cannabis use modify psychosis expression in first episode psychosis patients and population controls
2019
AbstractBackgroundDiagnostic categories within the psychosis spectrum are widely used in clinical practice, however psychosis may occur on a continuum. Therefore, we explored whether the continuous distribution of psychotic symptoms across categories is a function of genetic as well as environmental risk factors, such as polygenic risk scores (PRSs) and cannabis use.MethodsAs part of the EU-GEI study, we genotyped first episode psychosis patients (FEP) and population controls, for whom transdiagnostic dimensions of psychotic symptoms or experiences were generated using item response bi-factor modelling. Linear regression was used, separately in patients and controls, to test the association…
Interaction between cannabis consumption and childhood abuse in psychotic disorders: preliminary findings on the role of different patterns of cannab…
2015
Aim Several studies have suggested that lifetime cannabis consumption and childhood abuse synergistically contribute to the risk for psychotic disorders. This study aimed to extend existing findings regarding an additive interaction between childhood abuse and lifetime cannabis use by investigating the moderating role of type and frequency of cannabis use. Methods Up to 231 individuals presenting for the first time to mental health services with psychotic disorders and 214 unaffected population controls from South London, United Kingdom, were recruited as part of the Genetics and Psychosis study. Information about history of cannabis use was collected using the Cannabis Experiences Question…
