Now, there's more research on marijuana use, specific type of stroke and age:

A team led by Dr. Valerie Wolff, at the University Hospital of Strasbourg in France, examined 334 patients younger than 45 who suffered an ischemic stroke -- an attack caused by blocked blood flow to the brain. Fifty-eight of the patients were marijuana users.
The study couldn't prove that marijuana caused strokes, but Wolff's team did find some differences in stroke characteristics between pot users and non-users.
For example, a narrowing (stenosis) of the arteries in the skull was the cause of stroke in 45 percent of marijuana users, compared with only 14 percent of non-users, the findings showed. ...
The study appears in the Nov. 3 issue of the Journal of the American College of Cardiology. In a journal news release, editor-in-chief Dr. Valentin Fuster said that "the effects of cannabis have been considered benign for a long time; however, evidence continues to build about the relationship of its use with stroke."
