"Medical cannabis" is a broad term for any sort of cannabis-based medicine used to relieve symptoms.
Many cannabis-based products are available to buy online, but their quality and content is not known. They may be illegal in the UK and potentially dangerous.
Some products that might claim to be medical cannabis, such as CBD oil or hemp oil, are available to buy legally as food supplements from health stores. But there's no guarantee these are of good quality or provide any health benefits.
Specific cannabis-based products are available on prescription as medicinal cannabis. These are only likely to benefit a very small number of patients.
Can I get a prescription for medical cannabis?
Very few people in England are likely to get a prescription for medical cannabis.
Currently, it is only likely to be prescribed for the following conditions:
children and adults with rare, severe forms of epilepsy
adults with vomiting or nausea caused by chemotherapy
people with muscle stiffness and spasms caused by multiple sclerosis (MS)
It would only be considered when other treatments were not suitable or had not helped.
