what is theory
What is Theory?
  • A theory is an explanation for the occurrence of something
    • Scientific theory is an explanation that can be falsified empirically
  • That which we are attempting to explain here is:
    • The onset of drug use
    • Drug addiction
nature theory
Nature Theory
  • Suggest that predisposition to drug use and addiction are intrinsic to human nature
  • Early theories explained addiction in terms of being weak-willed, etc.
  • Andrew Weil suggests that use and addiction is rooted in a universal desire to alter consciousness

Timothy Leary

Andrew Weil

evaluation of nature theory
Evaluation of Nature Theory
  • Strength
    • Intuitively appealing
  • Weaknesses
    • Cannot be empirically verified or falsified
    • Cannot explain why individuals opt for a particular type of conscience-altering behavior
biological theories
Biological Theories
  • Emerged in 19th century in response to the moralistic “nature” theories
  • Used a “disease” model to explain addiction
    • As a disease, addiction was seen as something that was readily spread
    • Drugs were seen as “toxins” that destroyed the body
  • More recent biological theories have focused on the following two areas:
    • Neurochemical bases for addiction
    • Biogenetic bases for addiction
biological theories neurochemical explanations
Biological Theories:Neurochemical Explanations
  • Neurochemical explanations identify the source of addiction in neurotransmission, which can be defined as,
    • “the mechanism by which signals or impulses are sent from one nerve cell (neuron) to another” (Sunderwith, 1985)
  • The specific neurotransmitter varies across drug types:
    • Opiates – endorphins
    • Cocaine – dopamine
    • Antidepressants – serotonin
biological theories biogenetic explanations
Biological TheoriesBiogenetic Explanations
  • Genetic explanations suggest that some individuals are born with a genetically determined predisposition toward drug use and addiction
  • Genetic explanations rely primarily on epidemiological data to demonstrate this linkage
  • Much of the research in this area focuses on alcoholism
  • Four broad types of research
    • Animal studies
    • Family pattern studies
    • Twin studies
    • Adoption studies
evaluation of biological theories
Evaluation of Biological Theories
  • Neurochemical explanations have, to date, been applied to a small number of drugs
  • Biogenetic explanations:
    • Offer very strong epidemiological evidence for a genetic basis
    • There remain some critical questions, however:
      • Can we generalize from studies of alcoholism to other types of drugs?
      • Researchers have not identified the biogenetic mechanism that causes this genetic link
psychological theories
Psychological Theories
  • Grounded in more general theories of psychology that began to emerge in the 19th century
  • Focus primarily on the nature of individual experiences which might make one more susceptible to drug use and/or addiction
  • Four broad types:
    • Psychoanalytic explanations
    • Personality theories
    • Behavioral theories
psychological theories psychoanalytic explanations
Psychological Theories:Psychoanalytic Explanations
  • Based primarily on the work of Sigmund Freud
  • Identifies cause of drug addiction as abnormal personality development
  • Addiction the result of a search for compensatory gratification emanating from an unhealthy “fixation” at a certain point of personality development

Sigmund Freud

psychological theories personality theories
Psychological Theories:Personality Theories
  • Based on the notion that addiction is a manifestation of a unique type of personality
    • Lawrence Kolb suggested that addicted suffered from a sociopathic personality
    • More commonly, psychologists have pointed to an addictive personality
  • More recently, psychologists identify “personality characteristics” that tend to be associated with drug addiction
  • Jerome Jaffe suggested 3 personality features characteristic of marijuana users:
    • Non-conventionality
    • Open to new experiences
    • Lower rates of conventional achievement value

Jerome Jaffe

psychological theories behavioral explanations
Psychological TheoriesBehavioral Explanations
  • Modeling – Albert Bandura
    • Draws upon Skinner’s idea of operant conditioning
    • Suggests that individuals model behavior after significant others
  • Reinforcing factors in drug use
    • Euphoria
    • Cessation of withdrawal
    • Analgesic effects
    • Primary reinforcement vs. secondary reinforcement
    • Negative reinforcement
  • Cognitive Behavioral Theories – Alfred Lindesmith

Albert Bandura

sociological theories
Sociological Theories
  • Come from sociological theories explaining crime and deviance generally
  • Fall into 3 broad categories
    • Social Process Theories
    • Social Structure Theories
    • Societal Reaction Theores
social process theories learning theories
Social Process Theories:Learning Theories
  • Assumption: people are not born criminals or drug users, but learn these behaviors
  • Task: Determine how this learning takes place
  • Sutherland – Differential Association Theory
  • Akers – Differential Reinforcement Theory
  • Howard Becker – “Becoming a Marijuana User”

Edwin Sutherland

Ron Akeres

Howard Becker

social process theories control theories
Social Process Theories:Control Theories
  • Assumption: Human beings are predisposed toward maximizing self-interest; hence, everyone has the capacity to commit crime
  • Task: Must answer, “Why do most people not engage in drug use or crime?”
  • Travis Hirschi: The Social Bond

Travis Hirschi

social structure theories
Social Structure Theories
  • Focus is on why certain categories of people tend to be more involved in drug use or addiction
  • Three types of structural theories
    • Strain Theories
    • Cultural Deviance Theories
    • Integrated Structural Theory
strain theories merton
Strain Theories: Merton

Merton’s theory of “anomie” stressed two structural conditions:

The interaction of these conditions produce five adaptive responses:

strain theories cloward and ohlin
Strain Theories: Cloward and Ohlin
  • Theory of differential opportunity suggests that there are 2 opportunity structures: a legitimate and an illegitimate one
  • Drug users are double failures: they have failed to succeed in both
  • Such failure results in retreating from society altogether
evaluation of strain theories
Evaluation of Strain Theories
  • Has not stood up well under empirical scrutiny
  • Many street drug addicts are not even interested in achieving in the legitimate opportunity structure
  • Moreover, to sustain an expensive drug habit, usually requires success in the illegitimate opportunity structure
cultural deviance theories
Cultural Deviance Theories
  • Tradition has its beginning at the University of Chicago in the 1920’s
  • Application to subcultures of drug use in 1960’s by John O’Donnell at the University of Kentucky
    • Explained the emergence drug subcultures that arose in transitional neighborhoods
    • Suggested that criminalization of drugs posed a common problem to users of drugs in these neighborhoods: how to obtain regular supplies of the drug
    • Users learned to commit crimes and other creative ways to get these drugs
charles winick an integrated structural theory
Charles Winick:An Integrated Structural Theory
  • Attempted to explain drug dependence and addiction
  • Suggested that it is dependent on 3 factors:
    • Access to drugs
    • Disengagement from normative proscriptions against drug use
    • Role strain and/or deprivation
societal reaction theories
Societal Reaction Theories
  • Represent a “paradigm shift” in sociological theorizing
  • Rather focusing on why people engage in deviant (e.g., drug using) behavior, focus is on explaining why society reacts the way it does
  • Two theories identified with societal reaction framework
    • Labeling Theory
    • Conflict Theory
labeling theory
Labeling Theory
  • Three primary questions:
    • Why are certain behaviors defined as deviant?
    • Why are particular individuals labeled as deviant?
    • What is the effect of the label?
question 1 the defining of deviant behavior
Question #1: The Defining of Deviant Behavior
  • Argue that there is no necessary correlation between what is objectively harmful and what is illegal or considered deviant
  • Rather, the social construction of deviance involves a process of moral entrepreneurship
question 2 differential labeling of individuals
Question #2: Differential Labeling of Individuals
  • Note that not all individuals who engage in acts defined as deviant are so labeled
  • Moreover, those labeled are not necessarily the ones most seriously involved
  • Factors that seem to determine whether one is labeled are:
    • Visibility of deviant behavior
    • Disposition of deviant
    • Mobilization of community bias
question 3 impact of labeling
Question #3: Impact of Labeling
  • Suggest that labeling usually has a negative impact
    • Goffman – stigma
    • Becker – master status
    • Lemert – primary vs. secondary deviance
    • Tannenbaum – degradation ceremony

conflict theory
Conflict Theory
  • Based broadly on the classic work of Karl Marx
  • Elliot Currie suggests that heroin and crack use are concentrated in economically deprived inner cities:
    • Because economic opportunities are scarce
    • Resulting in perceived powerlessness and alienation
    • With the consequence of destroying individual and family life
  • According to conflict theorists, drug policy must address economic and political conditions which polarize social classes
