The family of a teenage boy from Cardiff fear they will not be able to afford the cannabis oil that stops their son having hundreds of seizures a day.
Bailey Williams, who is 17 and lives in Cardiff, suffers from epilepsy.
He has had the condition since he was two and it has caused him to have thousands of seizures.
At its worst, the condition makes Bailey fall to the floor and turn blue, while his parents have to sleep by his side each and every night in fear that he will suffocate against his pillow.
Things have improved in recent months for Bailey, who attends a special needs school in Penarth, because he has been taking cannabis-based medication.
The problem, however, is the cost, which can be up to £4,000 a month.
