Cannabis users have a greater stroke risk than non-users, according to a study by The University Hospital of Strasbourg.

The study looked at patients under age 45 admitted for stroke from 2005 to 2014. Those who used marijuana had a higher rate of ischemic stroke caused by intracranial arterial stenosis, the narrowing of arteries inside the brain. Among non-marijuana users, embolisms (blood clots in the brain) were the most common cause.

So if you consume cannabis, take note: it's smoking that seems to be the issue. The cannabis users in the sample were also more likely to be cigarette smokers, in addition to herb.

Yet another reason to stop smoking cigarettes or joints, in favour of vaping or edibles.
