It’s more than 20 years since the tobacco firm Philip Morris International Inc. commissioned a controversial research paper, “Public Finance Balance of Smoking in the Czech Republic,” which infamously argued that smokers cut state health care expenditure by dying early. The paper was considered an outrage and led to a high-profile apology from the company, after being widely derided by politicians and commentators internationally. The company’s July 9 proposal to buy the respiratory diseases firm Vectura Group plc for $1.2 billion is already looking just as provocative according to U.K. politicians and anti-smoking groups, who are calling for the government to intervene to stop it going ahead.
