Comments like Roy Beran's are exactly what has postponed the progress of cannabis medicine in this present day. Various forms and applications of non-psychoactive cannabis extracts are showing dramatic results with no negative side effects with nearly every child suffering from intractable seizures. He probably would rather them back on a cocktail of deadly drugs that don't even affect the frequency or severity of the seizures some of these kids are cripple by because they are in his scope of mainstream medicine. Get your heads out of the sand. The pros are clearly evident. Show me a con. Most of these anticonvulsants can kill and for some are completely ineffective, cannabis does no harm especially when we are talking about non-psychoactive applications.
