Survey results showed that participants who thought that they had received a multivitamin were predisposed to smoking more cigarettes and more likely to believe that they were invulnerable to harm, injury, and disease as compared with subjects who knew that they were given a placebo. Participants who believed they were given a multivitamin were also less likely to exercise and to choose healthier food, and had a higher desire to engage in "hedonic activities that involve instant gratification but pose long-term health hazards", such as casual sex, sunbathing, wild parties, and excessive drinking. In the 'multivitamin' group, the more supplements a participant used, the less likely they were to exercise, and smoking was highest among participants who expressed a conscious belief that multivitamins increased health.
