Cannabis and Psychosis: A Causal Association
2021
Nowadays, the use of cannabis is widespread around the world and THC content of confiscated cannabis has increased in the last years. This fact has raised some consequences, especially in the mental health of the people. Although there have existed some initial controversies about the relationship between cannabis and psychosis, at the present time there are some certainties of the causal association between them. Through the Bradford Hill postulates, we will try to demonstrate that cannabis produces psychosis. The strength of the association, the consistency along the studies, biological gradient, temporality, plausibility, coherence, experimentation, and analogies support the cause-effect…
Diferencias de género entre autocultivadores de cannabis en España
2019
The increase in cannabis use coincides with the proliferation of small-scale cannabis cultivation. These crops facilitate substance availability and increased use. Some investigations have studied the characteristics of small-scale cultivators; however, it is not known whether their profiles differ by gender. The aim of the present study was to analyse differences among growers regarding sociodemographic variables, patterns of use and health problems from a gender perspective. A descriptive observational study was designed with a sample of 219 cultivators (157 men and 62 women), aged between 18 and 34. Problematic use of cannabis (CPQ), cannabis dependence (SDS), patterns of abuse (CAST), r…
Cannabis-associated symptom profiles in patients with first episode psychosis and population controls
2019
AbstractObjectiveThe evidence is mixed on whether cannabis use is associated with a particular symptomatology in first episode psychosis (FEP) patients.The authors set out to investigate a) patterns of association between cannabis use and transdiagnostic symptom dimensions; b) whether the extent of use of cannabis contributes to the variation in clinical and subclinical symptom profiles.MethodThe authors analysed data from 901 patients and 1235 controls recruited across six countries, as part of the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. Item response modelling was used to estimate two bifactor models, which included genera…
The Stigmatization of Drug Addiction in South-East Turkey the Case of Drug Abuse Prevention Programme for Youth Project in Turkey
2022
Cannabis use undergoes a dynamic redefinition under selected legal frameworks globally. Many prevention programs face a dilemma between delivering abstinence objectives and pursuing more nuanced, harm reductionist aims. However, drug use in South-East Turkey is strongly stigmatized and is absent from the official life of the community, so neither of these discussions takes place. The authors participated in the development of a Drug Abuse Prevention programme for Youth and this article is grounded in qualitative data from Turkey. A follow-up study was conducted among the youth participants of a pilot phase of the program (n = 20), developed by an international group of professionals in the …

Vietējās kaņepju šķirnes „Pūriņi” augu ploiditātes un genotipu atšķirības molekulāro marķieru un eļļas specifisko īpašību nosakošo gēnu līmenī
2015
Sējas kaņepes (Cannabis sativ, L.) ir lauksaimniecībā nozīmīgs kultūraugs. Eiropas Savienības valstīs, arī Latvijā strauji pieaug interese par kaņepju audzēšanu. Pašlaik Latvijā nav savas sējas kaņepju šķirnes, kas būtu piemērotas sēklu iegūšanai. Jaunu šķirņu ātrākai iegūšanai ļoti nozīmīgas ir in vitro metodes, molekulāro metodžu izmantošana un iekļaušana selekcijas shēmā, tādēļ šim darbam ir sekojošs mērķis: vietējo kaņepju ‘Pūriņi’ in vitro kultivēšana, augu ģenētiskās daudzveidības un ploiditātes noteikšana, metilēšanas noteikšanas metodes izstrāde Δ12 un Δ15 desaturāzes gēnam. Veicot molekulāri ģenētisko analīzi izmantojot iPBS metodi konstatēts, ka vietējās kaņepes ‘Puriņi’ populācij…
Kanabisa auga izmantošanas medicīniskiem nolūkiem tiesiskā regulējuma problemātika Latvijā
2019
Kanabisa augu izsenis izmantoja medicīniskiem nolūkiem, tomēr 19.gadsimta vidū tā terapeitiskās īpašības tika noliegtas un starptautiskās konvencijās tas tika atzīts par sevišķi bīstamu narkotisko augu. Līdz ar to kanabisa auga aprite tika maksimāli ierobežota un tā izmantošana medicīniskiem nolūkiem bija praktiski neiespējama. Neskatoties uz ierobežojumiem, zinātniskā interese par kanabisa auga izmantošanu medicīniskiem nolūkiem atjaunojās un tika pierādīts, ka kanabisa augā esošām vielām – kanabinoīdiem ir terapeitiskās īpašības. Mūsdienās vairākās pasaules valstīs, kā arī vairākās Eiropas Savienības valstīs kanabisa auga izmantošana medicīniskiem nolūkiem ir atļauta. Bet joprojām daudzās…
Modulation of the Endocannabinoids N-Arachidonoylethanolamine (AEA) and 2-Arachidonoylglycerol (2-AG) on Executive Functions in Human.
2013
Animal studies point to an implication of the endocannabinoid system on executive functions. In humans, several studies have suggested an association between acute or chronic use of exogenous cannabinoids (Δ9-tetrahydrocannabinol) and executive impairments. However, to date, no published reports establish the relationship between endocannabinoids, as biomarkers of the cannabinoid neurotransmission system, and executive functioning in humans. The aim of the present study was to explore the association between circulating levels of plasma endocannabinoids N-arachidonoylethanolamine (AEA) and 2-Arachidonoylglycerol (2-AG) and executive functions (decision making, response inhibition and cognit…
Eventi di vita stressanti in un campione di pazienti affetti da psicosi all’esordio: prevalenza, sintomatologia ed età d’esordio
2011
Introduzione: Un consistente numero di studi suggerisce un’elevata prevalenza di eventi traumatici nella storia di soggetti con disturbi psicotici (Shevlin et al, 2008). Piu’ che l’impatto di un singolo evento di vita stressante, l’esposizione cumulativa ad esperienze traumatiche sembra incrementare il rischio di psicosi (van Winkel et al, 2008). Scopo dello studio e’ valutare la prevalenza di tali eventi in soggetti al primo episodio psicotico a confronto con controlli sani e la possibile correlazione con la sintomatologia psicotica e l’età di esordio. Metodologia: In atto sono stati reclutati 74 soggetti al primo episodio psicotico (51 m, 23 f; em=26.39, ds=9.36) e 27 controlli sani (18 m…
