FCE LISTNING PRACTICE : Smokers help the economy

Smokers help the economy:
The cost of cigarettes has increased by 40% since 2010. The cost will increase by $1 a year for the next four years to $20 a packet of 20 cigarettes. Will this make smokers quit smoking? Probably not, says a Treasury report, because smoking is addictive. The report also said that smokers help the economy. The sales tax on cigarettes from New Zealand-grown tobacco brought in $145m to the government in the 9 months to the end of March. The import duty on imported cigarettes brought in $746m for the same period.
However, smokers get sick and hospital care costs the government. A study done by the University of Otago in 2007 said that the actual cost to the Ministry of Health from illnesses caused by smoking was $300m to $350m a year. Also, the Treasury report said that smokers die early so there is a saving from National Superannuation and old-age health care.
However, Tariana Turia, co-leader of the Maori Party, wanted to increase the cost of a packet of cigarettes to $100 by 2025. She wants Maori to give up smoking and New Zealand to be a smoke-free country.
