Substance dependence and abuse

Substance Dependence and Abuse

Dependence ( Adiction)


  • Occupational or social problems, much time trying to obtain substance, continued use despite problems, etc.

  • Involves either tolerance or withdrawal

    • Tolerance

      • Greater amounts required to produce desired effect

    • Withdrawal

      • Physiological and psychological consequences when individual discontinues or reduces substance use

        • Restlessness, anxiety, cramps, death

    • Maladaptive use of substance

    • No physiological dependence

  • In 2006, 22 million met criteria for dependence or abuse.

    • Of those 15 million involved alcohol.

  • Alcohol dependence and abuse

    Alcohol Dependence and Abuse

    • Alcohol abuse

      • Negative social and occupational effects

      • No tolerance, withdrawal, or compulsive usage

    Etiology of substance related disorders developmental approach

    Etiology of Substance-Related Disorders: Developmental approach

    • Li et al. (2001) Two paths to alcohol abuse

      • First group began drinking in early adolescence, increased drinking throughout high school

      • Second group drank lesser amounts in early adolescence, increased drinking in middle school and again in high school.

        • Boys more likely to be in the first group, girls in the second group

    • Developmental studies do not account for all cases

      • Not an inevitable progression through stages

    Etiology of substance related disorders genetic factors

    Etiology of Substance-Related Disorders:Genetic Factors

    • Relatives and children of problem drinkers have higher-than-expected rates of alcohol abuse or dependence

    • Greater concordance in MZ than DZ twins

      • In men

        • Alcohol, caffeine, smoking, marijuana, & drug abuse in general

      • In women

        • Role of genetics less clear

        • Fewer available studies

        • Findings are mixed

    • Genetic and shared environmental risk factors for illicit drug abuse and dependence appear to be nonspecific

    • Ability to tolerate large quantities of alcohol may be an inherited diathesis

      • Asians have low rates of alcohol abuse

    • CYP2A6

      • Gene associated with metabolism of nicotine

      • Smokers with defect in this gene less likely to become dependent (Rao et al., 2000)

    Etiology of substance related disorders neurobiological factors

    Etiology of Substance-Related Disorders: Neurobiological Factors

    • Nearly all drugs, including alcohol, stimulate the dopamine system in the brain

    • Some evidence that people dependent on drugs or alcohol have a deficiency in the dopamine receptor DRD2

    • People take drugs to avoid the bad feelings associated with withdrawal

      • Explains frequency of relapse

    • Incentive-sensitization theory (Robinson & Berridge, 19983, 2003)

      • Distinguish

        • Wanting (craving for drug)

        • Liking (pleasure obtained by taking the drug)

      • Dopamine system becomes sensitive to the drug and the cues associated with drug (e.g., needles, rolling papers, etc.)

      • Sensitivity to cues induces & strengthens wanting

    • Brain imaging studies show that cues for a drug (needle or a cigarette) activate the reward and pleasure areas of the brain involved in drug use.

    Etiology of substance related disorders psychological factors

    Etiology of Substance-Related Disorders: Psychological factors

    • Mood alteration

      • Tension reduction may be due to “alcohol myopia” (Steele & Joseph, 1990)

        • User focuses reduced cognitive capacity on immediate distractions

        • Less attention focused on tension-producing thoughts

      • Effect similar for smoking

      • Cognitive distraction also reduces aggressive behavior in intoxicated individuals

      • However, alcohol and nicotine may increase tension when no distractions are present.

    • Expectancies about drugs effects influence behavior

      • People who expect alcohol to reduce stress & anxiety are most likely to drink

      • The greater perceived risk, the less likely it is to be used

    Etiology of substance related disorders psychopathology and personality

    Etiology of Substance-Related Disorders: Psychopathology and Personality

    • Personality factors that predict onset of substance related disorders:

      • Negative emotionality

      • Desire for increased arousal and positive affect

      • Constraint

        • Harm avoidance, conservative moral values, & cautious behavior

    • Kindergarten children who were rated high in anxiety and novelty seeking more likely to get drunk, smoke, and use drugs in adolescence.

    Etiology of substance related disorders sociocultural factors

    Etiology of Substance-Related Disorders: Sociocultural factors

    • Alcohol is the most common abused substance worldwide (Smart & Ogborne, 2000)

    • Men consume more alcohol than women but differences vary by country

      • Israel

        • Men drank 3x as much as women

      • Netherlands

        • Men drank 1½x as much as women

    • Availability

      • Usage is higher when alcohol and drugs are easily available

    Etiology of substance related disorders sociocultural factors1

    Etiology of Substance-Related Disorders: Sociocultural factors

    • Family factors

      • Parental alcohol use (Hawkins et al., 1997)

      • Psychiatric, marital, or legal problems in the family linked to drug abuse

      • Lack of emotional support from parents increases use of cigarettes, marijuana, and alcohol (Cadoret et la., 1995a)

      • Lack of parental monitoring linked to higher drug usage (Chassin et al., 1996; Thomas et al., 2000)

    Etiology of substance related disorders sociocultural factors2

    Etiology of Substance-Related Disorders: Sociocultural factors

    • Social network

      • Social influence or social selection?

      • Bullers et al.(2001) found evidence for both

        • Having peers who drink influences drinking behavior (social influence) but individuals also choose friends with drinking patterns similar to their own (social selection)

    • Advertising and Media

      • Countries that ban ads have 16% less consumption than those that don’t (Saffer, 1991)

    Treatment of substance related disorders alcohol abuse and dependence

    Treatment of Substance Related Disorders: Alcohol Abuse and Dependence

    • Inpatient hospital treatment

      • Detoxification

        • Withdrawal from alcohol under medical supervision

        • The therapeutic results of hospital treatment are not superior to those of outpatient treatment

    • Alcoholics Anonymous (AA)

      • Largest self-help group for problem drinkers

      • Regular meetings provide support, understanding, and acceptance

      • Promotes complete abstinence

      • Although some studies have shown AA participation predicts better outcome, recent studies suggest AA no more effective than other forms of therapy.

    Treatment of substance related disorders alcohol abuse and dependence1

    Treatment of Substance Related Disorders: Alcohol Abuse and Dependence

    • Couples and Family Therapy

      • Emphasizes support from problem drinker’s partner

      • Reduced problem drinking maintained1 year after therapy ended

      • Also reduced couples’ overall level of distress

    Treatment of substance related disorders alcohol abuse and dependence2

    Treatment of Substance Related Disorders: Alcohol Abuse and Dependence

    • Cognitive and Behavioral Treatments

      • Contingency-Management Therapy

        • Patient and family reinforce behaviors inconsistent with drinking

          • e.g., avoiding places associated with drinking

        • Teach problem drinker how to deal with uncomfortable situations

          • e.g., refusing the offer of a drink

        • AKA Community-reinforcement approach

      • Relapse Prevention

        • Strategies to prevent relapse

      • Brief motivational interventions

        • Designed to curb heavy drinking in college

    Treatment of substance related disorders alcohol abuse and dependence3

    Treatment of Substance Related Disorders: Alcohol Abuse and Dependence

    • Controlled drinking

      • Belief that problem drinkers can consume alcohol in moderation

      • Avoid total abstinence and inebriation

      • Guided self-change

    • Medications

      • Antabuse (disulfiram)

        • Produces nausea and vomiting if alcohol is consumed

      • Other medications include naltrexone, naloxone, & acamprosate

        • Most effective when combined with CBT

    Treatment of substance related disorders nicotine dependence

    Treatment of Substance Related Disorders: Nicotine Dependence

    • Peer behavior important

      • If others in social network stop smoking, increases likelihood that individual will also stop

    • Rapid smoking treatment

      • Rapid puffing, focused smoking, & smoke holding

    • Scheduled smoking

      • Reduce nicotine intake gradually over a few weeks

    • Physician’s advice

      • By age 65, most smokers have quit (USDHHS, 1998b)

    • Nicotine replacement treatments

      • Gum, patches, or inhalers

      • Reduce craving for nicotine

      • Combining patch with antidepressants improved success rate

    Treatment of substance related disorders illegal drug abuse and dependence

    Treatment of Substance Related Disorders: Illegal Drug Abuse and Dependence

    • Detoxification central to treatment

    • Psychological treatments

      • Desipramine and CBT showed effectiveness for cocaine use

        • CBT especially helpful for users with high dependence levels (Carroll et al., 1994, 1995)

      • Operant conditioning

        • Tokens that can be traded for desirable goods are given to users who abstain (Dallery et al., 2001)

      • Motivational interviewing or enhancement thereapy

        • CBT plus Rogerian therapy effective for alcohol and drug use (Burke et al., 2003)

      • Self-help residential homes for heroin users

        • Non-drug environment

        • Group therapy

        • Guidance and support from former users

    Treatment of substance related disorders illegal drug abuse and dependence1

    Treatment of Substance Related Disorders: Illegal Drug Abuse and Dependence

    • Drug replacement treatments and medications

    • A meta-analysis of stimulant medication as a treatment for cocaine abuse revealed little evidence that this type of medication is effective

    • Heroin replacements

      • Synthetic narcotics

        • Methadone, levomethadyl acetate, bupreophine

        • Used to wean heroin users from dependence

      • More effective if combined with psychological support & treatment (Lilley et al., 2000)
