Researchers at the Harvard School of Public Health analyzed nicotine yield of cigarettes sold in Massachusetts from 1997 to 2005. The result: cigarette manufacturers have been gradually boosting the level of addictive nicotine by an average of 1.6% per year, or 11% over the 7 year period studied.

Something to bear in mind while watching re-runs of the South Park episode “Butt Out“, in which Parker and Stone bravely defend the cigarette corporations for providing a little harmless pleasure to people, who after all smoke of their own free will.
