Nicotine In American Cigarettes Up By 11 Per Cent
`New research shows that the level of nicotine in major brands of American cigarettes has gone up by 11 per cent in the period 1998 to 2005. [..]
The scientists examined annual data submitted by tobacco manufacturers to the Massachusetts Department of Public Health (MDPH). [..]
Upon analysing the data the scientists found that the manufacturers have increased the level of smoke nicotine yield in cigarettes by an average of 1.6 per cent for each year between 1998 and 2005. And they did this in two ways. First by directly altering the concentration of nicotine, and secondly by changing the design features to increase the delivery efficiency of nicotine.’
