“Marijuana and marijuana-based products have been used to treat medical disease.
Recently, derivatives of the plant have been separated or synthesized to treat various neurological disorders, many of them affecting children.
Unfortunately, data are sparse in regard to treating children with neurologic illness. Therefore, formal conclusions about the potential efficacy, benefit, and adverse effects for these products cannot be made at this time.
Further robust research using strong scientific methodology is desperately needed to formally evaluate the role of these products in children.”
