Casey Costello's hit back at health advocates over criticism of her heated tobacco tax cut. 

The Associate Health Minister cut the tax by 50% in an effort to encourage use of the products instead of smoking. 

Costello has faced a tense reception regarding the move. 

But she told Heather du Plessis Allan she's working hard to reduce smoking rates, despite what she calls "the noise". 

She says the Health Coalition became fixated on the tobacco industry, not Costello's plans to reduce smoking rates.
