Study: History Of Cannabis Use Not An Independent Risk Factor For Stroke

Stockholm, Sweden: The use of cannabis is not an independent contributing factor to the risk of stroke in those under 60 years of age, according to population-based data published online ahead of print in the journal Stroke.

An international team of investigators from Sweden and France assessed the relationship between marijuana use and stroke risk in a population-based cohort of over 49,000 men. Researchers reported “no significant association between cannabis use in young adulthood and overall incidence of stroke” in those less than 60 years old. By contrast, the use of alcohol and tobacco “showed clear dose-response shaped associations” with stroke.

They concluded, “[B]y examining cannabis use in young adulthood in relation to subsequent risk of stroke in a large population-based cohort, we found no evident association between cannabis use and stroke, including stroke before 45 years of age.”
