Cannabis Use in Children With Pantothenate Kinase-Associated Neurodegeneration.

Cannabis use was commonly reported among children with pantothenate kinase-associated neurodegeneration whose parents responded to a survey, particularly when many other dystonia treatments had been tried. Physicians should be aware that parents may treat their child with severe, painful dystonia with cannabis. Placebo-controlled studies of products containing cannabidiol and 9-tetrahydrocannabinol are needed for pediatric tone disorders.
