What Were We Asked?
We were asked whether there was any research evaluating the effectiveness of cannabidiol (CBD) for controlling epileptic seizures in children.
- Cannabidiol (CBD) and Tetrahydrocannabinol (THC) are two drugs derived from the cannabis plant which have been shown in experiments to have anti-epileptic properties.
- There is evidence that THC can have harmful effects on the developing brain, research has therefore concentrated on the use of CBD as a treatment for epilepsy in children.
- In July 2018 UK law was changed to allow medical practitioners to prescribe cannabis-based products to patients with exceptional clinical need. However, there is currently no agreement in the UK as to how ‘medicinal cannabis’ is defined.
- Research evidence suggests some children with rare forms of childhood epilepsy (Lennox-Gastaut Syndrome and Dravet Syndrome) or epilepsy which does not respond to standard medication, may benefit from the use of cannabis-based products.
- Grown cannabis or 'artisanal' cannabis cannot be safely used in place of prescribed cannabis-based products.
- Any use of cannabis-based products should be under expert medical supervision.
