New case studies link smoking synthetic marijuana with stroke in healthy, young adults
Date:11/19/2013

Tampa, FL (Nov. 19, 2013) -- Add stroke to the list of severe health hazards that may be associated with smoking synthetic marijuana, popularly known as spice or K2, a University of South Florida neurology team reports.

An advance online article in the journal Neurology details case studies by the USF neurologists of two healthy, young siblings who experienced acute ischemic strokes soon after smoking the street drug spice. Ischemic strokes occur when an artery to the brain is blocked.

Seizures, abnormal heart rhythms, heart attacks, psychosis, hallucinations and other serious adverse effects have been associated with smoking synthetic pot. Medical journals have also begun to report a growing number of strokes potentially related to the use of natural (non-synthetic) marijuana.

"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," said senior author W. Scott Burgin, MD, professor of neurology at the USF Health Morsani College of Medicine and director of the Comprehensive Stroke Center at Tampa General Hospital.

"To the best of our knowledge, what appeared to be heart-derived strokes occurred in two people with otherwise healthy hearts. So more study is needed."

USF vascular neurology fellow Melissa Freeman, MD, was lead author of the paper.

Synthetic marijuana refers to a mixture of herbs, often resembling lawn clippings, that have been sprayed or soaked with a solution of designer chemicals intended to produce a high similar to cannabis when consumed. Spice can be much more potent than conventional marijuana because of the more complete way the psychoactive ingredient in the synthetic product binds to the brain's cannabinoid receptors, Dr. Burgin said.
