A new study suggests that people who smoke ‘spice’ or synthetic marijuana have an increased risk of stroke.

The researchers conducted a number of examinations on the siblings to find whether there were any genetic reasons that had predisposed them to strokes at such a young age but were unable to find any. The study has been published in the journal Neurology.
“Since the two patients were siblings, we wondered whether they might have any undiagnosed genetic conditions that predisposed them to strokes at a young age. We rigorously looked for those and didn't come up with anything. To the best of our knowledge, what appeared to be heart-derived strokes occurred in two people with otherwise healthy hearts”, Burgin said.
