ScienceDaily Summary:

Marijuana use may result in heart-related complications in young and middle-aged adults. Nearly 2 percent of the health complications from marijuana use reported were cardiovascular related. A quarter of these complications resulted in death, according to a study. Surveillance of marijuana-related reports of cardiovascular disorders should continue and more research needs to look at how marijuana use might trigger cardiovascular events, researchers say.

WTR-RI Research Team Note:

This study involves a review of “59 cannabis-related stroke cases in 30 published articles including 4 reviews and only 1 report linking cannabis use and cardiovascular events.”  In their conclusions, the authors report:

“In regard to the literature, cannabis-related stroke is not a myth, and a likely mechanism of stroke in most cannabis users is the presence of reversible MIS induced by this drug.  The reality of the relationship between cannabis and stroke is, however, complex because other confounding factors have to be considered (ie, lifestyle and genetic factors).”

WTR-RI Research Team Note:

This study involves a review of 3 instances of marijuana related stroke in adolescent males who had used marijuana prior to the event.  Two resulted in death and the third resulted in permanently impacted mobility.  The author’s conclusions include the observation that “Episodic marijuana use may represent a risk factor for stroke in childhood, particularly in the posterior circulation. Early recognition of the cerebellar stroke syndrome may allow prompt neurosurgical intervention, reducing morbidity.”
