The most 100 cited papers in addiction research on cannabis, heroin, cocaine and psychostimulants. A bibliometric cross-sectional analysis

2021

The number of citations a peer-reviewed article receives is often used as a measure of its importance and scientific impact. This paper identifies, describes and categorizes the highly cited papers in addiction research on cannabis, heroin, cocaine and psychostimulants. Highly cited papers were identified in the Web of Science Core Collection database. Several bibliometric indicators were calculated. Social network analysis was applied to draw groups of authors and institutions with the greatest number of collaborations and co-words. The number of citations for the top 100 cited articles ranged from 649 to 4,672. The articles were published in 40 journals. The subject category Substance Abu…

In vitro contamination of hair by marijuana smoke.

2004

Abstract Background: The deposition of cannabinoids on/into hair from environmental smoke can be considered as a potential source of drug findings in hair. We studied external uptake of cannabinoids from marijuana smoke, investigating possible influencing factors on drug uptake and the efficiency of decontamination procedures. Methods: Strands of a natural hair sample were moistened with water, greased with sebum or sebum/sweat, or bleached or permed. Treated and untreated samples were exposed to marijuana smoke for 60 min. Aliquots of each hair strand were either kept unwashed or were washed with methanol, dichloromethane, or 5 g/L dodecyl sulfate in water. Cannabinoid concentrations in un…

Detectability of cannabinoids in the serum samples of cannabis users: Indicators of recent cannabis use? A follow‐up study

2021

Forensic toxicologists are frequently required to predict the time of last cannabis consumption. Several studies suggested the utility of minor cannabinoids as indicators of recent cannabis use. Because several factors influence blood cannabinoid concentrations, the interpretation of serum cannabinoid concentrations remains challenging. To assess the informative value of serum cannabinoid levels in cannabis users (in total N = 117 patients, including 56 patients who stated an exact time of last cannabis use within 24 h before blood sampling), the detectability of cannabinoids, namely delta-9-tetrahydrocannabinol (delta-9-THC), 11-hydroxy-delta-9-THC, 11-nor-9-carboxy-delta-9-THC, cannabichr…

The Relationship Between Dissociative Experiences and Cannabis Use: a Systematic Review

2019

Purpose of Review This systematic review aimed to investigate the relation between cannabis use and dissociation. Recent Findings Four analytical and 14 descriptive cross-sectional studies were included. There is no variation in the rates of cannabis use among individuals with dissociative experiences compared with the general population. In addition, the prevalence of dissociative disorders in subjects using cannabis is not different from those not using cannabis. The majority of the studies employed inadequate sampling procedures and a concurrent or retrospective assessment of the two variables, which might have increased the risk of bias, and only a few of them controlled for potential c…

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…

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…

A gloss to the Supreme Administrative Court judgement of 17 July 2018 (II GSK 844/18)

2020

yrok, którego dotyczy glosa, prezentuje przełomowe stanowisko Naczelnego Sądu Administracyjnego, w którym sąd uznał, że decyzja Ministra Zdrowia w przedmiocie odmo-wy udzielenia zgody na refundację leku zawierającego medyczną marihuanę narusza prawa pacjenta w zakresie wyboru skutecznej metody leczenia, podczas gdy inne konwencjonalne metody okazały się nieskuteczne. W ocenie sądu ewentualne wątpliwości – zarówno co do wykładni przepisów dotyczących ochrony zdrowia, jak i oceny stanu faktycznego konkretnej sprawy – rozstrzygać należy na rzecz ochrony życia i zdrowia ludzkiego. Leczenie prepa-ratami zawierającymi medyczną marihuanę wpisuje się w nurt in dubio pro vita humana.

The association of cannabis use with fast-food consumption, overweight, and obesity among adolescents aged 12-15 years from 28 countries

2022

Background: Cannabis legalization and use have risen globally. However, the association between cannabis use, eating behaviors and body weight among adolescents is yet unexplored. Objectives: This study examined the association between cannabis use, fast-food consumption, overweight and obesity in 28 countries using data from the 2010–2016 Global School-Based Student Health Survey. Methods: Multivariable logistic regression and meta-analysis were performed among a sample of 83,726 adolescents (48.7% females) aged 12–15 years, mean (SD) age of 13.8 (0.9) years. Results: The overall prevalence of cannabis use (in past 30 days) and fast-food consumption (in past 7 days) were 2.8% and 57.3% res…

The role of health literacy in the association between academic performance and substance use.

2022

Abstract Background To address social inequalities in adolescent substance use and consequent disparities in health, it is important to identify the mechanisms of the association between substance use and academic performance. We study the role of health literacy (HL) in the association between academic performance and weekly smoking, monthly alcohol use and cannabis ever-use among adolescents in Europe. Methods SILNE-R school survey data, which was collected in 2016–17 with paper-and-pencil-method from Hanover (GE), Amersfoort (NL) and Tampere (FI), were used (N = 5088, age 13–19). Health Literacy for School-aged Children instrument was used to assess students’ HL. Logistic regression anal…
