We present the case of a woman with reversible vasoconstriction syndrome and associated intraparenchymal hemorrhage following repeated vaping.

This report highlights one of the first cases illustrating the neurotoxic potential of vaped cannabis oils. Clearly, increased research and more evidence is needed to examine the potential neurological effects of widespread vaping as it becomes more easily accessible across the globe.
