In a landmark decision, the island’s government voted to change the law to allow such products to be used.
At the moment, one medicine containing cannabis is available in the island, via the hospital pharmacy.
It’s much the same picture in the UK, where only specialist doctors are allowed to issue similar treatments.
Professor Michael Barnes said the island’s GPs and their patients will have to find out more about it before its widely used.
There are many doctors who are uncertain about this and don’t understand the differences between street and medical cannabis. So we have an education programme to do for the doctors so they can prescribe safely and with confidence, and an education to do with members of the members of the public who might be scared of the change. It’s easy to explain and we just need to step forward and put on those educational programmes.
