It sounds reasonable, but our resources are already stretched to the limit, how are we going to enforce it?

Smoke-free outdoor areas are low cost and yet have a very high return in terms of promoting good health. Where policies have been implemented internationally there has been no need for enforcement per se.

The focus has been on public education especially through appropriate signage. Experiences in New Zealand have been similar, for example in South Taranaki and Upper Hutt.
