Billy Caldwell, who was not expected to survive infancy due to severe epilepsy, recently celebrated his 21st birthday. His mother, Charlotte, recalls how Billy was sent home to die in 2005, but his story became instrumental in the legalisation of cannabis medicine in the UK. Billy, who is also autistic, celebrated his milestone birthday at home in Northern Ireland with family and friends, marking a joyous occasion and a triumph for better access to prescription cannabis for families in need.
