Disease concept is a theory of addiction and is a way of showing that addiction is like all the other things we generally accept as diseases. If the behavior of drinking or using drugs is a sign of addiction, then it is no surprise that measuring drinking or using behavior brings no uniform picture of the disorder. In virtually all illnesses, especially early in their course, signs and symptoms are remarkably variable. Just as fevers may be high or low; pain severe or mild; alcoholic drinking or addictive drug use may be heavy or light, intermittent or continuous, boisterous or quiet-all depending on biological, social and psychological factors influencing the individual with the disorder.
