A mum is begging doctors to give her two-year-old daughter cannabis to cure her epileptic seizures . Jenna Heary says little Olivia suffers up to 100 fits a day but her current medication is ineffective. Jenna, 22, from Preston, said: “I’m trying to get Olivia onto a trial using medical cannabis oil or cannabidiol to see if it can control her seizures. “In one child I heard of, it reduced her seizures by about 50 per cent. “Olivia has 100 plus seizures every day, she’s on six different medications and a Ketogenic diet to help control them but it doesn’t work. “I want to get her on a trial to make her just that little bit more comfortable and if it reduces her seizures that would be a real bonus. It’s our last resort.” Jenna, who is also mum to five-year-old Kailen, told how Olivia had a three-hour seizure at nine months that almost killed her. Trials have showed how cannabidiol, derived from cannabis, reduced seizures by nearly 40 per cent in children with a form of drug-resistant epilepsy.
