Nicotine boost was deliberate, study says
Key Excerpts from Article on Website of Boston Globe

Data supplied by tobacco companies strongly suggest that in recent years manufacturers deliberately boosted nicotine levels in cigarettes to more effectively hook smokers, Harvard researchers conclude in a study being released today. The companies increasingly used tobacco richer in nicotine and made design changes to give smokers more puffs per cigarette, according to the analysis from the Harvard School of Public Health. The report expands on a landmark Massachusetts Department of Public Health study issued last August showing that the amount of nicotine that could be inhaled from cigarettes increased an average of 10 percent from 1998 through 2004. A 1996 state law required cigarette makers to test the nicotine that could be inhaled from their products, and the state ordered the use of machines that simulate a typical smoker's puffing. The Harvard researchers, who corroborated the basic findings of the state study, wanted to determine why cigarettes were delivering more nicotine. "Industry says it's changed," said Greg Connolly, an author of the Harvard study. "They've changed -- maybe for the worse." The Harvard study relies on information supplied by the industry. "It was systematic, it was pervasive, it involved all the manufacturers, and it was by design," said Dr. Howard Koh, an associate dean at the Harvard School of Public Health and an author of the study. Another author said that the likelihood that the nicotine increase happened by chance was less than 1 in 1,000.
