Researchers Confirm Rising Nicotine Rates

Phillip-Morris denies it, but a new Harvard study confirms a study done earlier this year finding that nicotine levels in cigarettes have increased over the last decade:

Researchers at the Harvard School of Public Health say they have confirmed a study released last year by health officials in Massachusetts that found steadily increasing levels of nicotine in cigarettes sold in the state from 1997 to 2005. The analysis, based on data submitted to the Massachusetts Department of Public Health by cigarette manufacturers, found that increases in smoke nicotine yield per cigarette averaged 1.6 percent each year, or about 11 percent over a seven-year period.
