Este artigo propõe uma investigação multidisciplinar, histórico-filosófica e etnobotânica sobre a constituição do Museu Brasileiro da Cannabis, abordando seus pressupostos políticos, epistemológicos e ancestrais. A partir de um diálogo entre estudos canábicos, epistemologias do Sul, mitologia comparada, filosofia da ciência e crítica cultural, o trabalho reconstrói genealogias esquecidas da...
Cannabis is a widely used illicit substance that is historically consumed via smoking, but alternative methods of cannabis consumption have been growing in popularity over the past several decades. One such modality is vaporization, which can appeal specifically to adolescent consumers given these pen devices’ ease of concealment, lack of characteristic odor, and marketability. Cannabis...
Childhood trauma is a well-established risk factor for psychosis, paranoia, and substance use, with cannabis being a modifiable environmental factor that exacerbates these vulnerabilities. This study examines the interplay between childhood trauma, cannabis use, and paranoia using standard tetrahydrocannabinol (THC) units as a comprehensive measure of cannabis exposure. Data were derived from...
Cannabis-induced psychosis (CIP) represents a significant public health concern in the context of increasing global cannabis use and potency. This review synthesizes current evidence on the epidemiology, neurobiological mechanisms, clinical features, and treatment approaches for cannabis-induced psychotic disorders. Recent epidemiological data indicate rising incidence rates of CIP, with...

Chronic marijuana use has been linked to negative effects on executive functions, but there is uncertainty with recreational, sporadic, and non-dependent use. This article reports and analyzes the results of a systematic review of the evidence that has evaluated this issue specifically in young people. Only two studies that met the inclusion criteria were identified in the OVID, Embase and...
Social factors significantly influence the initiation and progression of cannabis use and cannabis use disorder. Although cannabis is the most widely used drug globally, its social cognitive aspects and neural correlates have rarely been studied. To evaluate the findings to date and to guide future research, this systematic review assesses neuroimaging evidence on the associations between...
Cue-induced craving-the desire to use a drug triggered by exposure to cues associated with prior use-is a central mechanism in the development and maintenance of problematic substance use behaviours. Drug cues have the power to induce craving even in long-term abstinent individuals, which has led clinicians to advise patients to avoid the people, places and objects that are associated with...
Δ9-tetrahydrocannabinol (THC) is responsible for the intoxicating (psychotropic) effects of cannabis and cannabis-derived products currently available in the legal and illegal markets. The psychotropic effects of THC are produced via activation of CB1 cannabinoid receptors in the brain, which are normally engaged by endogenous cannabinoid (endocannabinoid) substances. Outside the brain, THC...
Heavy and daily use of cannabis with high contents of Δ9-tetrahydrocannabinol (THC) during adolescence is associated with an increased risk of developing psychotic disorders later in life. Here, we treated mice with THC during adolescence and found that this exposure impaired social interaction and increased vulnerability to develop sensorimotor gating deficiencies comparable to those...
Cannabis use represents a significant risk factor for both psychotic disorders and suicidal behaviors, with growing evidence suggesting complex interactions between these variables. This systematic review examines the relationship between cannabis use and suicide risk in first-episode psychosis (FEP) patients, and explores underlying mechanisms, moderating factors, and intervention strategies....
