Hot on the heels of Redford's proposal to increase the sin tax for cigarettes and alcohol, she is now mulling over a plan to get drivers to butt out when they are driving with children.

Redford confirmed on Tuesday that new smoking legislation is in the works.

She promises to ban smoking inside cars when children are present, but isn't clear on when the proposal will become law.

The premier is also looking into ban flavoured tobacco products as a part of the same legislation.
