"The legislation covers the smoking of tobacco or anything that contains tobacco, or smoking any other substance, including manufactured cigarettes, hand-rolled cigarettes, pipes and cigars.
This means that anything that is smoked is covered by smokefree law, including manufactured and hand-rolled cigarettes, pipes, cigars, herbal cigarettes and water pipes (including shisha, hookah and hubble-bubble pipes)."
