Rationale: As cannabis legalization increases globally, understanding its impact on stroke risk is critical. Cannabis usage is believed to link to increased stroke due to impact on orthostatic tension (a sudden rise in blood pressure). There have been mixed research results because cannabis users often use nicotine, tobacco and/or alcohol.

Method: A wide demographic of men and women in their 20s, 30s, and 40s were surveyed. They were asked to self report cannabis use frequency and history of strokes.

Results: Weekly cannabis users were 4.7 times more likely to have a stroke than non users. Strokes in those who frequently used cannabis and smoked tobacco were prevalent in their 40s. Regardless of health and age, cannabis users were 2.3 times more at risk of strokes.

Meaning: Heavy cannabis use can significantly impact heart health. The frequency of the usage increases the risk. Coverage of the impact of cannabis on cardiovascular health should remain at the forefront of public health awareness.
