Two experiments designed to assess the relationship between coffee intake and smoking are reported. In Experiment I, coffee drinking smokers were randomly assigned to four groups in which they received 0, 1, 2, or 3 cups of coffee during two one-hour sessions while they worked on crossword puzzles. Results showed that subjects receiving coffee in any amount smoked more than subjects who were not provided coffee. Moderate and low rate smokers were then randomly assigned to one of five groups in Experiment II, in which they were provided no drink, water, Postum (a coffee substitute), caffeinated, or decaffeinated coffee. These groups were selected to assess the characteristic of coffee that may have influenced increased smoking. Results for number of cigarettes smoked and puff rate generally showed that subjects receiving caffeinated or decaffeinated coffee smoked more than subjects in the no drink or water control groups. The results of this study provide experimental evidence of the role of coffee in setting the occasion for smoking, as well as ruling out the presence of a liquid or caffeine as the important characteristics of coffee in influencing smoking.
