The APA’s DSM lists two broad categories of diagnoses in this area: dependence and abuse. So we have alcohol dependence and alcohol abuse; amphetamines dependence and amphetamines abuse; cocaine dependence and cocaine abuse. And so on.
Dependence is defined by the presence of three or more of the following criteria:
tolerance, as defined by either of the following: a need for markedly increased amounts of the substance to achieve intoxication or desired effect markedly diminished effect with continued use of the same amount of the substance withdrawal, as manifested by either of the following: the characteristic withdrawal syndrome for the substance … the same (or a closely related) substance is taken to relieve or avoid withdrawal symptoms the substance is often taken in larger amounts or over a longer period than was intended there is a persistent desire or unsuccessful efforts to cut down or control substance use a great deal of time is spent in activities necessary to obtain the substance… use the substance … or recovery from its effects important social, occupational, or recreational activities are given up or reduced because of substance use the substance use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance … Abuse is defined as one or more of the following: recurrent substance use resulting in a failure to fulfill major role obligations at work, school, or home … recurrent substance use in situations in which it is physically hazardous … recurrent substance-related legal problems … continued substance use despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effect of the substance … Let’s consider alcohol dependence, which to all intents and purposes is what most people would refer to as alcoholism. A person who drinks, say, half a bottle of whisky every day, who never appears particularly drunk, who becomes extremely sick if he stops drinking, who has made numerous unsuccessful efforts to quit, who has incurred some liver damage, and whose social life has been severely curtailed because of drinking, would normally be called an alcoholic. Some people prefer the term addicted and would describe him as addicted to alcohol. DSM would say that he has a mental disorder called alcohol dependence. The problem with all three terminologies is that they encourage us to blur the distinction between a description and an explanation. This distinction is the central theme of this blog.
