Each year the average American obtains 5.8 prescription drugs and, additionally, takes numerous over-the-counter medications. The total annual cost of prescribed medicines is $5.75 billion, a figure that does not include costs for about 950 million prescriptions dispensed to hospital inpatients and another $4 to 8 billion for OTC medicines. These drugs are taken to prevent, cure, or alleviate a wide variety of diseases and symptoms, both real and imaginary, mild and serious. Questions of interest to attribution theorists regarding this drug use process include the following: what events lead to decisions to initiate, modify, or discontinue drug therapy; what sources of information about one's state of health are used to judge a drug's success or failure; what causal explanations accompany these judgments? This paper explores drug use from an attribution perspective, with a special focus on how people interpret physical and behavioral events before, during, and after drug therapy.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
