Our post about Office Romance: Sometimes a cigar is just a cigar prompted this little bit of research. Freud on smoking:
"[Cigars have] served me for precisely fifty years as protection and a weapon in the combat of life...I owe to the cigar a great intensification of my capacity to work and a facilitation of my self-control."
Another:
"My boy, smoking is one of the greatest and cheapest enjoyments in life, and if you decide in advance not to smoke, I can only feel sorry for you."
