A nearby non-smoker may be exposed to more nicotine from a filtered cigarette than the person who is smoking it, a researcher reported. S. Katherine Hammond of the University of Massachusetts said that although filtered cigarettes dilute the smoke inhaled by the smoker, they emit the same ash and smoke particles into the surrounding air as unfiltered cigarettes. She said that could mean that non-smokers are exposed to more nicotine from filtered cigarettes than the smokers, but not necessarily that they inhale more of it.
