A smoking ban in school grounds, playgrounds and hospital grounds is expected to be introduced today as part of Wales' Public Health Bill.
The Welsh Government said the Bill aims to improve the nation’s health, with a particular focus on children's wellbeing.
The legislation also includes proposals to introduce a licensing scheme for special procedures, such as acupuncture, body piercing, electrolysis and tattooing, and bans the intimate piercing of anybody under the age of 16.
In March, the Bill previously failed to receive enough votes in the Senedd.
It proposed to ban the use of e-cigarettes in some public places.
