As more states legalize marijuana and its use becomes more prevalent, there have been numerous studies about its potential risks and benefits. In particular, there have been a number of conflicting results regarding marijuana use and increased stroke risk, with some studies stating that it reduces the risk while others argue that it exponentially increases the risk. According to a recent study by a team of neurologists at the University of Mississippi Medical Center, there is no link between increased stroke risk and marijuana use.
The team analyzed data from nearly 10,000 individuals and they found that cannabis use does not increase your risk of having a stroke. “Previous studies that investigated cannabis use and risk of stroke have had conflicting results, some showing a decreased risk and others showing a greatly increased risk,” says Carmela San Luis, MD, lead investigator and a member of the American Academy of Neurology (“AAN”).
“Our observational study looked specifically at recent cannabis use by reviewing drug testing data for people admitted to the hospital. While more research is needed with larger numbers of people, our study lends support to the studies showing that cannabis use does not increase the risk of stroke.” San Luis and a team of colleagues from the University of Mississippi in Jackson designed the study to assess potential correlations between marijuana use (a positive cannabinoid urine drug screen on admission) and a diagnosis of an acute ischemic stroke.
They studied de-identified data from 9,350 patients who were 18 years old and over admitted in the University of Mississippi Medical Center from 2015 -2017, and only 18% of the patients tested positive for cannabis use. Ischemic stroke was observed in 7.91% (130) of the 1,643 individuals who tested positive for cannabis and in 15.66% (1207) of those who tested negative. The database also granted the researchers access to information related to age, ethnicity, sickle cell disease, family history of stroke, hypertension status, obesity, diabetes mellitus, cigarette smoking, atrial fibrillation, carotid artery stenosis and other cardiac conditions. They were included as confounders in the researchers’ multivariate logistic regression analysis.
San Luis notes that the study only captured whether people had used marijuana recently and that it did not collect information on how much marijuana was consumed or any other information about their history of prior use.
“Our research adds to the list of studies with conflicting results, so it’s important to continue to investigate stroke risk and cannabis use. Future studies are now needed in larger groups of people that not only include data from drug screenings but also from dosing amounts and a person’s history of cannabis use.”
Industry watchers say the findings of such studies are of interest to sector players like SinglePoint, Inc. (OTCQB: SING) since the industry would greatly benefit once reliable third-party information is widely available on the various myths and misconceptions circulating about marijuana.
