PURPOSE OF REVIEW: In the last few years, the attitude toward marijuana in many parts of the world has shifted from illicit to legalized for medical use and to decriminalized. In parallel, there has been a gradual increase in the consumption of this product in the general population, particularly among adolescents and young adults. Marijuana is generally perceived as a harmless drug. However, data obtained in observational studies and preclinical models have established associations between cannabis use and cardiovascular events. In addition, there is emerging evidence linking marijuana use to cerebrovascular complications. Here we provide a critical review of the literature with special emphasis on the association of cannabinoids with stroke and the possible pathogenic mechanisms involved.

RECENT FINDINGS: Ischemic and hemorrhagic stroke have been described in association with cannabis use, particularly in young individuals. Cerebral infarction remains the most commonly reported stroke subtype seen in marijuana users. Several pathogenic mechanisms have been proposed to explain this association, including multifocal intracranial stenosis, reversible cerebral vasoconstriction syndrome, and coexisting vascular risk factors. Cannabis use is increasingly recognized in young individuals presenting with acute stroke. Our understanding of the pathogenic mechanisms associated with cannabis use and stroke is limited but rapidly evolving. Healthcare providers should educate patients about the potential cardiovascular and cerebrovascular complications related to marijuana or cannabinoids use.
