The effects of cannabis on epilepsy have been under discussion for a number of years.
However, there does seem to be anecdotal evidence that cannabis can reduce seizures in some people. This is thought to be because of the non-psychoactive component of cannabis called cannabidiol or CBD.
Research into CBD is ongoing for its uses in other conditions such as multiple sclerosis and cancer.
In epilepsy it is thought to act as an anticonvulsant and therefore may reduce seizures but it is not yet clear how this works. Although there is some very limited information on its effects on adults, there is currently no efficacy or safety data in children in the use of the pure form.
Recently regulatory approval has been given to the use of cannabidiol oil (pure CBD) in a limited number of children with a range of different epilepsies in the USA.
In the UK, trials in children are actively being discussed, however it is important that any trial is undertaken with the appropriate safety and regulatory.
