“…In other words, we tested a three-way interaction (Parent Injunctive Norms X Social Anxiety X Tension Reduction Expectancies) and hypothesized that injunctive norms would interact with tension reduction expectancies and social anxiety to predict greater cannabis craving. These efforts may inform theoretical models regarding cannabis use behavior, and facilitate tailoring specific cannabis use disorder treatments (Dervaux & Laqueille, 2012). …”

Objectives-Socially anxious cannabis users are influenced by cannabis expectancies and normative perceptions. The present study examines the influence of psychosocial factors on cannabis use vulnerability factors as the result of interactions between norms perceptions, social anxiety, and expectancies.Methods-Participants were 149 (36.2% female) current cannabis users aged 18-36 (M=21.01, SD=3.09). Hierarchical multiple regressions were employed to investigate the predictive value of the social anxiety X injunctive norms X expectancies interaction on cannabis cravings.Results-A three-way interaction emerged in the prediction of cannabis cravings. Simple slopes analyses showed that among individuals with perceptions of greater parent approval of cannabis use (higher injunctive norms), social anxiety was associated with greater cannabis craving when expectancies regarding relaxation and tension reduction were greater (t=2.54, p=.01, β=1.12).Conclusions-Among cannabis users with perceptions of greater injunctive norms, social anxiety was associated with greater cannabis craving when tension reduction expectancies were greater. However, social anxiety was unrelated to cannabis craving when expectances were low. This suggests that cannabis craving among socially anxious adults was greatest when cannabis use was viewed as acceptable and expected to reduce tension, and highlights the importance of considering norms, expectancies, and social anxiety in understanding cannabis-related behaviors.

“…In the literature, only limited number of case reports was described to have stroke possibly related to cannabis use; yet there is only one patient described with a hemorrhagic stroke associated with cannabis use [1][2][3]. To best of our knowledge, here, we report the first case of both hemorrhagic and ischemic stroke following high doses of cannabis consumption.…”

“…Although case reports and population-based studies have demonstrated a clear temporal relationship between stroke and cannabis use, it is still difficult to establish a causal relationship [1][2][3]. Most of the reported cases are younger than 50 years without any vascular risk factors; though concomitant alcohol and tobacco consumption were suggested as potential triggering factors [4,5].…”

“…Des complications ont été observées dans un tiers des cas : nécessité d'une nécrosectomie chirurgicale caudale [1], crises épileptiques [4], infarctus splé-niques (notre observation) et nutrition entérale prolongée un mois pour intolérance alimentaire [5]. La consommation de cannabis peut favoriser la survenue d'une artérite, voire d'une vascularite systémique [10]. Dans notre observation, ce mécanisme vasculaire apparaît peu probable pour expliquer le TABLEAU I Principales caractéristiques des cas publiés de pancréatites aiguës induites par le cannabis [1][2][3][4][5][6][7][8] développement d'une thrombose isolée de l'artère splénique au contact de la pancréatite caudale, sans autre localisation vasculaire ni manifestation générale systémique.…”

“…L'injection avant ou après le déclenchement de la PA se concluait respectivement par une aggravation ou une améliora-tion de la PA, amenant à évoquer le rôle d'une stimulation neurologique sensitive. Avec l'actuelle banalisation de la consommation de cannabis [10], cette cause devrait être de plus en plus fréquemment envisagée dans le diagnostic étio-logique d'une PA. Une majoration des doses consommées dans les semaines précédant la PA pourraient constituer un facteur déclenchant. La détection de cannabis dans les urines, possible jusqu'à une semaine après la prise, peut étayer un diagnostic rétrospectif.…”
