Children are said to be at risk from misconceptions about the dangers of vaping.

A Cancer Society survey has found 90 percent of secondary schools had students vaping during school time, and almost one in 10 primary schools.

Researcher Candace Bagnall told Mike Hosking it's easy for children to get hold of e-cigarettes.

“Schools all around the world are struggling with this issue because it's happened so quickly."
