After Nigel died, Katie decided to volunteer with Smokefree South West, a partnership of 15 local authorities working alongside the NHS to support people trying to quit.

“I think I’m able to share that message that quitting smoking is one of the best things people can do for their health and that it’s not too late to quit smoking and have more time with your family members,” she said.
