STORY BEHIND THE DATA:
The Federal Trade Commission annually rates varieties of domestic
cigarettes according to their tar, nicotine, and carbon monoxide
content.  The United States Surgeon General considers each of these
substances hazardous to a smoker's health.  Past studies have shown
that increases in the tar and nicotine content of a cigarette are
accompanied by an increase in the carbon monoxide emitted from the
cigarette smoke.
          
The data presented here are taken from Mendenhall and Sincich (1992)
and are a subset of the data produced by the Federal Trade Commission.
