Some patterns of drug self-administration harm the user or other individuals without producing offsetting therapeutic or other benefit. The harm may involve direct physical damage, as when chronic high-dose alcohol intake eventually leads to cirrhosis, or indirect physical damage, as when an intoxicated driver maims innocents in an automobile accident. The unwise use of drugs is a major cause of suffering and death; in 1977 alone, the lives of 500,000 Americans ended prematurely due to the misuse of cigarettes, alcohol, and other drugs (Pollin, 1979).
