"We've seen children that have had rather severe reactions while on medical marijuana products," said Amy Brooks-Kayal, M.D., a Colorado pediatrician who is president of the American Epilepsy Society. "We don't know if that's from the medical marijuana product or something else, because it wasn't done in a controlled setting."
Dr. Brooks-Kayal supports the clinical trials underway now across the country, and advises parents not to treat their sick children with cannabis oil until clinicial trials are complete.
"Just because a single child or person or even a few may respond well to a treatment, that doesn't mean that the majority of them will," she said.
