Consumo di cannabis, gruppo dei pari e strutturazione del Sè in adolescenza
2011
La conquista di un nuovo senso di identità e la rappresentazione di essa come frutto dell’integrazione delle trasformazioni psico-fisiche che travolgono il proprio corpo, è un percorso lento e di certo non privo di tensioni, che si snoda nel corso di tutta l’adolescenza. La costruzione identitaria adolescenziale non è però solo un processo intrapsichico, essa si articola anche attraverso il confronto che il giovane ha all’interno dello spazio sociale che lo circonda, mediante il rapporto con i pari ed i nuovi ruoli sociali progressivamente ricoperti. In questa fase di vita, il gruppo dei pari assume nuove valenze e funzioni specifiche, fornendo un modello di confronto e identificazione con …
Cannabis e Psicosi, un contributo di ricerca
2017
si descrivono i dati relativi ad un campioni di pazienti affetti da disturbo psicotico all'esordio, come parte del progetto SGAP (Sicilian Genetic and Psychosis. tra i fattori di rischio implicati nell'insorgenza del disturbo si prende in esame il ruolo del consumo di cannabis mettendo a confronto i pazienti con un gruppo di cntrollo costituito da soggetti non psicotici. Emerge come l'età media di insorgenza del disturbo psicotico è stata più precoce per coloro che avevano fumato cannabis nel corso della vita (24.2 anni vs. 31.6 anni) mentre non è stata riscontrata nessuna differenza in relazione all'uso recente di cannabis.
Consumo di cannabis e pattern psicopatologico di pazienti al primo episodio psicotico: confronto tra due campioni
2011
Alcuni studi in letteratura supportano l’associazione tra consumo di cannabis, età di esordio ed espressività psicopatologica nei pazienti al primo episodio psicotico (Orlandi, 2001). Questo lavoro si propone di analizzare la gravità della sintomatologia psicotica in relazione al consumo di cannabis, confrontando due campioni di pazienti all'esordio psicotico (FEP) reclutati a Palermo e a Londra.
Smoke High-Potency Cannabis and Become Psychotic Younger?
2016
PURPOSE: Cannabis use is associated with an earlier age of onset of psychosis (AOP). However, the reasons for this remain debated. METHODS: We applied a Cox proportional hazards model to 410 first-episode psychosis patients to investigate the association between gender, patterns of cannabis use, and AOP. RESULTS: Patients with a history of cannabis use presented with their first episode of psychosis at a younger age (mean years = 28.2, SD = 8.0; median years = 27.1) than those who never used cannabis (mean years = 31.4, SD = 9.9; median years = 30.0; hazard ratio [HR] = 1.42; 95% CI: 1.16-1.74; P < .001). This association remained significant after controlling for gender (HR = 1.39; 95% …
DOES CANNABIS USE WORSEN PSYCHOTIC SYMPTOM PRESENTATION?
2017
Background: While the relationship between cannabis and psychosis is well established, there is a lack of studies into whether cannabis use is associated with a particular pattern of symptoms at psychosis onset. Moreover, there is much evidence that psychotic experiences are common in the healthy population, and again their relationship with exposure to cannabis has been scarcely studied. We hypothesized that psychopathology in first-episode psychosis patients (FEP), and psychotic experiences in controls, would be qualitatively and quantitatively affected by pattern of cannabis use. Methods: The Operational CRITeria (OPCRIT) system, the CAPE (Community Assessment of Psychic Experiences), an…
SOME OF THE INDIVIDUAL DIFFERENCES IN RISK TO DEVELOP PSYCHOSIS AMONG CANNABIS USERS CAN BE EXPLAINED BY WHERE THEY LIVE AND BY THEIR AGE AT FIRST USE
2018
Background Cannabis use remains the most widely used recreational drug worldwide. Following from several USA states legalisation policies, European countries are reconsidering their cannabis laws. While a significant amount of Epidemiological evidence has reported that cannabis use increases the risk of psychosis it is still unclear: 1) what underpins individual differences in developing a psychotic disorder following cannabis use; 2) if variations in availability of cannabis have affected rate of Psychotic disorders across Europe. Methods Using detailed data on lifetime pattern of cannabis use from the EUGEI first episode case-control study (N=2300) and the available Incidence rates of Psy…
Prenatal exposure to cannabinoids evokes long-lasting functional alterations by targeting CB 1 receptors on developing cortical neurons
2015
The CB1 cannabinoid receptor, the main target of Δ(9)-tetrahydrocannabinol (THC), the most prominent psychoactive compound of marijuana, plays a crucial regulatory role in brain development as evidenced by the neurodevelopmental consequences of its manipulation in animal models. Likewise, recreational cannabis use during pregnancy affects brain structure and function of the progeny. However, the precise neurobiological substrates underlying the consequences of prenatal THC exposure remain unknown. As CB1 signaling is known to modulate long-range corticofugal connectivity, we analyzed the impact of THC exposure on cortical projection neuron development. THC administration to pregnant mice in…
Externalizing Behaviors and Cigarette Smoking as Predictors for Use of Illicit Drugs: A Longitudinal Study Among Finnish Adolescent Twins
2010
We examined whether externalizing problem behaviors (hyperactivity–impulsivity, aggressiveness, and inattention) predict illicit drug use independently, or whether their associations with drug use are mediated through cigarette smoking. We used a prospective longitudinal design within theFinnTwin12-17study among Finnish adolescents with baseline at age 12 and follow-up surveys at ages 14 and 17. Path models were conducted withMplusand included 1992 boys and 2123 girls. The outcome was self-reported ever use of cannabis or other illicit drugs at age 17. The predictors were: externalizing behaviors (hyperactivity–impulsivity, aggressiveness, and inattention) assessed by teachers and parents (…

Analysis of Contact Traces of Cannabis by In-Tube Solid-Phase Microextraction Coupled to Nanoliquid Chromatography
2018
Because of its inherent qualities, in-tube solid-phase microextraction (IT-SPME) coupled on-line to nanoliquid chromatography (nanoLC) can be a very powerful tool to address the new challenges of analytical laboratories such as the analysis of traces of complex samples. This is the case of the detection of contact traces of drugs, especially cannabis. The main difficulties encountered in the analysis of traces of cannabis plants on surfaces are the low amount of sample available (typically <
