- •Marijuana use is most common in young, male, African American and Medicaid patients.
- •The incidence of AIS is higher in marijuana users compared to non-marijuana users.
- •Risk of marijuana-associated AIS increases with concurrent use of tobacco ± cocaine.
- •Marijuana use increases the likelihood of AIS, adjusting for stroke risk factors.
- •Marijuana use predicts symptomatic cerebral vasospasm, a proposed mechanism of AIS.
