Big Tobacco funds free-market think tanks

I was shocked - shocked - by this story from the Guardian last week:

Two of Britain's leading free-market thinktanks have been criticised for taking money from "big tobacco". The Adam Smith Institute (ASI) and the Institute of Economic Affairs (IEA) have received tens of thousands of pounds in funding from leading tobacco companies. 

Their admissions have dismayed health groups, which question the degree to which both organisations have influenced government thinking, especially on plain packaging for cigarettes. It also highlights the entrenched links between "big tobacco" and the libertarian strand of British politics that has been strengthened by the recent rise of Ukip, a party that has positioned itself firmly on the side of smokers.
