In the lecture, the woman cast her doubts on three points to against the benefits of increasing taxes on purchasing cigarettes and other unhealthy products that have been mentioned in the reading part.

Firstly, she thinks that higher taxes will encourage people to consume cheaper cigarettes and foods, which contain more unhealthy ingredients. As a consequence, people who indulge in these products will become more unhealthy rather than becoming healthier.

Secondly, she purpose that the opinion of increasing taxes on people who consume unhealthy products is financially fair because these people are predisposed to get some diseases, and creating more medical costs actually is unfair. Because it neglected that the price of the same box of cigarettes occupies different portions of different people's income. So increasing taxes will put more burdens on people with lower incomes.

Thirdly, she concerns that once the government has received this big amount of money, it will depend on this money. And being reluctant to lose it. Maybe the government will cancel the smoking bans in public areas to increase taxes further on unhealthy products consuming. It drives things in the opposite way.

These three points above showed that why this woman disagrees with the policy of increasing taxes on purchases of cigarettes and unhealthy products.
