It’s a story often found in Colorado; a family moves here seeking medicinal marijuana treatments.

The same applies for Yvonne Cahalane and her two-year-old Tristan, who moved from Ireland in December.

“He's a very social little guy and he's a little devil,” said Yvonne of her son. “He's a trooper he always comes out of [his seizures] smiling.”

Tristan has Dravet’s syndrome. It’s a condition that causes seizures in young children.

In Tristan’s case, he would experiences more than 20 a day.

“It was a constant cycle and a constant battle,” she said. “He was always in a fog. That's the best way to describe it. He wouldn't answer you all the time.”

He started using CBD oil, and within days his seizures began subsiding. But Yvonne’s visa is set to run out in December, at which time she and Tristan will have to move back to Ireland, where Tristan’s treatments aren’t legal.

“If he were to go back to Ireland without the cannabis that works for him, and after coming off four drugs, and that's a health risk in itself, he would absolutely certainly have long seizures again,” she said.

Yvonne and her husband have been putting pressure on lawmakers in Ireland.

“It's not fair people can't have this,” she said.

She hopes their efforts lead to change, but worries about how long it will take. She also worries what their next move will be if it is unsuccessful.

“We would just like to go home,” she said. “We would just like to go home and have Tristan on safe medicine.’

A recent poll in Ireland finds 40 percent of the Irish people support legalizing medical marijuana.
