Who could have imagined that four of the professional staff members at my workplace would make such a change?  Once avid cigarette smokers, these people–two nurses and two docturs–have recently taken up chewing tobacco.  Part of the reason for that is the ban on cigarette smoking on our property.  I think it also comes down to health concerns as well.  No one can argue about the increased incidence of lung and throat cancer among cigarette smokers.  Who wants to see their physician sucking on a cigarette?  You can kind of go off into a corner and dip or use other tobacco products, however.  There are definitely advantages.
