BOSTON: Data supplied by tobacco companies strongly suggest that manufacturers in recent years deliberately raised nicotine levels in cigarettes to more effectively hook smokers, Harvard University researchers conclude in a study that was to be released Thursday.
The companies increasingly used tobacco richer in nicotine, and also 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.
