Alfred Charles True and Albert Warren Ferris, The New International Encyclopædia…
“ Before the full maturity of the system is attained, even the smallest amount of smoking is hurtful; subsequently, the habit is generally prejudicial. Smoked just after a meal a cigar is said to act as a digestive stimulant, and as a food when other forms of nourishment are not procurable. In some persons smoking increases, in others diminishes mental activity. Chewing is considered the most deleterious form in which to use tobacco. The different kinds of tobacco exert a different influence on the smoker according to the amount of noxious ingredients which they contain. ”
