If you smoke marijuana, a new study found that you have an increased risk of cerebrovascular effects related to the use of cannabinoids or stroke.
The results, presented at the World Congress on Stroke in Montreal, showed an increase in the incidence of stroke among marijuana users from 2010 to 2014, while the overall prevalence of stroke remained stable .
According to researchers at the University of Toronto, more than 80 million people currently live with the effects of stroke around the world.
For the study, the team evaluated the use of the drug rivaroxaban versus acetylsalicylic acid (ASA) to prevent stroke in patients with left atrial hypertrophy of the heart.
The study examined a total of 2.3 million hospitalizations among people who used marijuana for recreational purposes, of which 32,231 had a stroke, of which 19,452 were victims of a stroke. Acute ischemic stroke – a sudden loss of blood flow to an area of the brain.
"We see a very intriguing signal here, and it has a biological plausibility, but it will require independent validation before modifying the recommendations of the practice," said co-author David Gladstone, an associate professor at the university.
The results showed that the rate of stroke of all types among marijuana users increased from 1.3 to 1.5%. In addition, the rate of ischemic stroke increased from 0.7 to 0.9%, the team said.
During the five-year period, the prevalence of strokes in all patients was stable, the results revealed, they added.
The researchers concluded that these growing trends in stroke among marijuana users "warrant further prospective studies to evaluate the association between stroke and marijuana in a context of legalization of marijuana." recreational use ".
