Title: The Basics of Drugs


1
The Basics of Drugs
  • Neurology and Chemistry
  • Neurons are nerve cells
  • Neurons send electrical impulses
  • Different body parts
  • Different cells
  • Neurons determine
  • Autonomic functions
  • Voluntary functions

2
The Basics of Drugs (2)
  • Neurons release chemicals called
  • Neurotransmitters
  • Neurotransmitters act on specific sites called
  • Receptors
  • Specific Neurotransmitters fit into specific
    receptors (key in lock)

3
The Basics of Drugs (3)
  • The relationship between transmitter and receptor
    is relative, not specific!
  • The better the fit the greater the stimulation
  • Transmitter/Receptor Affinity
  • High Affinity Strong Effect
  • Low Affinity Weak Effect

4
The Basics of Drugs (4)
  • Psychoactive Drugs
  • Cross the blood-brain barrier
  • No blood-brain barrier crossing, no psychoactive
    effect
  • Different routes of administration result in
    different levels of blood-brain cross over

5
The Basics of Drug Pharmacology
  • All drugs have multiple effects
  • Main effects the intended result of a drug
  • Side effects the effects of the drug that are
    not intended
  • Effect Dose (ED) is the amount of a drug needed
    to produce the intended effect
  • ED50 is the amount needed to produce the effect
    in 50 of a species
  • ED100 the amount needed for 100 of the
    population

6
The Basics of Drug Pharmacology (2)
  • Toxicity refers to the drugs ability to kill
    the organism
  • Cause harm to one or more of the organs in an
    organism
  • Lethal Dose (LD) the amount need to kill an
    organism
  • LD50 kill 50 of the population
  • LD100 kill 100

7
The Basics of Drug Pharmacology (3)
  • Drug Margin of Safety
  • How far apart is the ED from the LD for a given
    drug?
  • Barbiturates have a low margin of safety
  • Marijuana has a high margin of safety
  • Multiple Drugs Complicate
  • Additive greater effect
  • Antagonistic cancel effect
  • Synergy multiply effect

8
Drug Classifications
  • Stimulants methamphetamines, amphetamines
    (Dexedrine), cocaine, caffeine, Ritalin, nicotine
  • Antidepressants Prozac, Zoloft, Lithium
  • Sedatives Barbiturates, Quaalude, Valium
  • Hallucinogens LSD, mescaline, peyote, MDMA
    (ecstasy), psilocybin
  • Analgesics opiates (opium, morphine, heroin,
    codeine), opioids (methadone,, Demerol, Darvon)
    non-narcotic - Tylenol, ibuprofen, aspirin
  • Cannabis

11
Three Major Neurotransmitters
  • Serotonin
  • Effects sleep, mood, and dreams - is increased by
    the use of Methamphetamine
  • Dopamine
  • Effects motor movement, is involved in pleasure
    and is related to psychosis
  • Norepinephrine
  • Effects heart rate, blood pressure, sweating,
  • Dilates pupil, lungs and constricts blood vessels

12
Addiction
  • No universally accept definition
  • Four common definitions in competition for
    dominance
  • Quantity and frequency definition
  • Psychological dependence definition
  • Physical dependence definition
  • Life problems definition
  • Brain Injury definition

13
Quantity and Frequency Definition of Addiction
  • Once per week
  • 3-5 times per week
  • Everyday Use
  • Problems
  • Individual factors influence the effects based on
    quantity (Habituation, age, weight, etc.)
  • Binge users dont fit into the definition
  • Yearly average may be low but, the pattern of use
    reveals excessive amounts in short periods of
    time

14
Psychological Dependence Definition of Addiction
  • Experience psychological discomfort as a
    withdrawal symptom
  • Do you use after a bad time?
  • Do your friends use less than you?
  • Problems
  • Moderate users could also answer yes to many of
    the questions
  • Definition is very subjective
  • Difference between habit and dependence?

15
Physical Dependence Definition of Addiction
  • Clear physical withdrawal symptoms must be
    present
  • Shakes
  • Cramps
  • Problems
  • Too restrictive to be useful
  • Problem abusers are not included

16
Life-ProblemsDefinition of Addiction
  • Medical problems (e.g. liver)
  • Family problems (divorce, abuse)
  • Career problems (loss of job, no promotion)
  • Criminal Justice problems (arrests, convictions)
  • Problems
  • Sub-culture/ cultural definitions of problems
  • Medical problems are not straight per dose
    outcomes (not all develop a common medical
    problem)

17
Brain Injury Definition
  • Both neurotransmitters and receivers
  • Damaged so that only the active chemical will
    trigger the release of dopamine (or serotonin, or
    norepinephrine)
  • Only the chemical can generate happiness
  • Thus, there is no way to scare someone out of
    addiction
  • Similar to if you breath I am going to hurt
    you.
  • What things make you really happy?
  • Research shows that most injuries begin to heal
    after 8 or 9 month of abstinence
  • Some drug require longer periods of abstinence to
    begin healing

18
Chronic use depletes dopamine and is toxic to the
neuron.
19
HOW DRUGS WORK
  • Multidimensional
  • Economic
  • Political
  • Pharmacological
  • Psychological
  • Sociological

20
Drugs A Symbolic Phenomena
  • Drug Effect are Contingent
  • Pharmacology represents potential effects
  • Potential effects are dependent on the social
    context
  • 1970s Reports on the effects of THC
  • Lab animal studies
  • Real life experience

21
The Basics of Drug Pharmacology (4)
  • Physical Tolerance
  • Certain quantity of drug
  • Extended period of time
  • Diminished effects
  • Behavioral Tolerance
  • Experience user
  • Learns the effects
  • Compensates for effects
  • Reverse Tolerance
  • Over time
  • Users become more sensitive to the effects
  • Cross Tolerance
  • Tolerance to a drug in one category
  • General tolerance to other drugs in the category

22
Drug Effects/Objective and Subjective
  • Factors Influencing Drug Effects
  • Identity
  • Dose
  • Potency (purity)
  • Drug mixing
  • Route of administration
  • Habituation

23
Identity
  • What is actually in the drug?
  • Bogus substances
  • Is the drug as advertised?
  • Regular mushrooms as psilocybin
  • Oregano as pot

24
Dose
  • What is the amount of the drug that has been
    taken?
  • Some dose levels will have no effects on anyone
  • Some dose levels can have negative effects no
    matter what the drug

25
Potency and Purity
  • Potency is the quantity of drug that will produce
    a given effect
  • Potency varies between drugs, but also within the
    same drug
  • Marijuana with 1 THC verses 10-12
  • Alcohol 4-5 verses 10-12
  • Purity is the percent of the active ingredient
    present
  • Cocaine varies in purity from 20 to 50 or more
    percent purity
  • Most drugs are stepped on, cut with non active
    fillers

26
Mixing
  • Many (most) people rarely take one drug at a time
  • Which drugs are mixed can have a powerful effect
    on the effect
  • John Belushi mixed cocaine and heroin in an
    injection
  • To understand drug effects something must be
    known about interaction effects (additive,
    multiplier, or synergy)

27
Administration Route
  • In general the fast the route to the brain the
    stronger the effect of the drug
  • Smoking a drug is the fastest route
  • All the bodies blood passes through the lungs
    every minute
  • Injecting a drug causes the drug to be mixed with
    (diluted) non drugged blood

28
Habituation
  • How accustomed is the user to the drug?
  • The tolerance factor decreases the drug effect
  • Experienced drinkers can handle much more alcohol
    and still act straight than non-experienced
    drinkers

29
Set and Setting
  • Set refers to the psychic, mental state of the
    user
  • Expectations
  • Mood
  • Setting refers to the social and physical
    environment of the drug use
  • Micro level living room, or party
  • Macro level culture, normative culture

30
DRUGS AS SOCIAL
  • Drug taking is close to cultural universal
  • 2-3 million prescription/year
  • Average 37.50/each
  • 15 billion in over counter sales/year
  • 52 drink alcohol
  • 29 smoke tobacco
  • 150 billion in illegal drug sales
  • 65 million have tried marijuana

31
What is a Drug?
  • Chemical Properties
  • Definable Biological Effect
  • One Common Definition
  • Any substance that causes or creates significant
    psychological or physiological changes in the
    body.
  • Would include vitamin C, chocolate, and car
    exhaust

32
What is a Drug?
  • The term drug is a social construction
  • Does not mean, imaginary effects
  • Does not mean, no objective effects
  • Does not mean, calling something a drug will make
    it a drug
  • Definitions change over time and place
  • Alcohol, tobacco, cocaine

33
Drug Definition Categories
  • Medical Substances used in connection with
    healing the body or mind
  • Penicillin, aspirin, morphine, lithium
  • Psychoactive Substances used in connection with
    altering the state of consciousness
  • LSD, alcohol, amphetamine, Salvia
  • Illegal Substances that have been defined as
    against the law for the general public by a
    political authority
  • marijuana, heroin
  • Public Substances the general population thinks
    of as a drug.
  • Crack, ice, ecstasy

34
What is Drug Abuse?
  • A Disease?
  • A Medical Pathology?
  • A Sickness?
  • There is an implication that abuse invariably
    involves observable physical damage
  • Most definition do not include physical or mental
    harm

35
Drug Abuse
  • Use of a psychoactive substance in a manner that
    is illegal or outside medical practice.
  • or
  • Use of a drug that is outside the legally
    accepted list of substances. Using illegal drugs
    is abuse.

36
Drug Abuse (2)
  • In 1973 the National Commission on Marijuana and
    Drug Abuse recommended
  • The term drug abuse be deleted from official
    pronouncements and public policy dialogue. The
    term has no functional utility and has become no
    more than an arbitrary codeword for that drug use
    which is presently considered wrong.

37
Drug Abuse (3)
  • For the class purpose
  • Abuse will refer to the use of a substance (legal
    or illegal) in a way that causes clear physical
    or mental harm.
  • Does not include getting into trouble while using
    a drug
  • But, does include an inability to function on
    important social levels
  • Dropping out of school
  • Getting fired from work
  • Domestic upheaval

38
Drug Use as a Social Problem
  • Objective level of understanding
  • A phenomenon that creates societal harm or damage
  • Causes death
  • Social deterioration
  • Impairs quality of life
  • The greater the number of people involved the
    more important the social problem.

39
Drug Use as a Social Problem (2)
  • Subjective level of understanding
  • Social problems do not exist in an objective way.
    They are not like trees!
  • Social problems are constructed through social
    definitions
  • Phenomenon become social problems through a four
    stage process
  • Agitation
  • Legitimation
  • Legislation
  • Re-emergence

40
Drug Use as a Social Problem (3)
  • Combining the objective and subjective levels of
    social problems
  • Most social problems should be considered from
    both perspectives
  • Objective Tobacco kills more than other drugs
  • Subjective
  • Dose-for-dose basis
  • Years of life lost
  • Acute v. Combined effect

41
Drug Panic
  • Several key factors are generally involved in
    constructing a drug panic
  • Explosion of a new evil drug (Crack in 1985)
  • Deaths of notable people (Len Bias Crack
    Babies)
  • Media coverage (placement of stories in coverage)
  • Public concern (Independent of objective numbers)
  • Political expression (Leaders take advantage of
    issue)
  • Prominent spokesperson (Nancy Reagan)

42
The Process of Criminalization
  • What is a Crime?
  • A behavior that has been formally prohibited by a
    political authority.
  • Who is a Criminal?
  • Those who have been labeled as criminal by a
    political authority (Judge).
  • Criminalization has an objective and subjective
    component
  • Objectively Behavior is illegal based on the
    potential extent of harm to society.
  • Subjectively Behavior is illegal based on the
    extent that they interfere with the interests of
    the influential.

43
Criminalization of Drugs
  • Objectivist See drug legislation as a matter of
    public health and safety
  • Subjectivists See drug legislation as a matter
    of cultural, political, and economic concerns

44
Criminalization of Drugs (2)
  • Most drug legislation in the 20th century was
    motivated by political, moral, and economic
    reasons, rather than genuine concern for public
    health.
  • Cocaine 1914 from fear that blacks using cocaine
    committed violent acts
  • Alcohol 1919 from fear that poor immigrant
    Catholics using alcohol were committing violent
    acts
  • Marijuana 1933 from fear that Mexicans using
    marijuana committed violent acts
  • The more poor the users of a drug are perceived
    to be the more likely the passing of legislation
    against the use of the drug.

45
Sex and Drug Use
  • Does drug use represent a special problem for
    women?
  • Women value love relationships more than men
  • Drugs interfere with love oriented relationships
  • Women, more often than men, are responsible for
    child rearing
  • Women are responsible for fetal health
  • Drug addiction frequently represents unique
    problems for women.

46
Sex and Drug Use (2)
  • Drug use is a gendered phenomenon
  • Stigmatization is greater for women than men
  • Prostitution is a faster way of making money than
    most other options available to women
  • Distribution is usually controlled by men, while
    women are almost as likely to use as men
  • Many men conceptualize sex as exploitation the
    sex for drugs transaction degrades women, but
    leaves men's identity intact

47
Sex and Drug Use (3)
  • The odds of male to female transmission of AIDS
    is 10 times greater than the likelihood of female
    to male transmission
  • Drug use is troubling for mother who are held
    responsible for the fate of the fetus they carry
  • Society arrests mother who use crack, but no
    punishment has been devise for alcohol use
  • Most treatment programs are designed for men
  • Peer confrontation techniques provoke poor
    responses from women
  • Some will not even admit women

48
Theories of Drug Use
  • Biological Theories
  • Genetic Factor
  • A gene or combination of genes influences the
    specific biological mechanism for substance
    abuses
  • Animals can be breed to prefer alcohol over other
    beverages
  • No researcher asserts that genetic factors are
    the only, or even principle factor in compulsive
    drinking

49
Biological Theories (2)
  • Metabolic Imbalance
  • Some inability or over-ability to metabolize
    specific chemicals produces a craving for the
    drug
  • Heroin addicts physiology craves opiates the same
    way that diabetics crave insulin
  • No biological mechanism has been discovered
  • No proposed hormonal imbalance has been identified

50
Psychological Theories
  • Positive Reinforcement
  • The euphoria generated by the drug causes the
    user to want to repeat the use experience.
  • The more positive the drug experience, the
    greater the tendency to re-use the drug.
  • Addiction is not necessary for continued (or
    continuous) use of the drug.
  • A sufficient history of reinforcement will compel
    a high rate of use in the drug user.
  • Addiction is simply the end point along the
    continuum of use. (Euphoria Seekers)

51
Psychological Theories (2)
  • Negative Reinforcement
  • The user does drugs to avoid or seek relief from
    pain (physical or mental is irrelevant).
  • Therefore, drug use is rewarding because it
    relieves the painful experience.
  • If the drug user reaches a point on the continuum
    of use where dependency is reached, continued use
    results to avoid the pain of withdrawal.
  • In the dependency (or addiction) condition the
    drug user is attempting to feel normal by doing
    the drug.

52
Psychological Theories (3)
  • Inadequate Personality Theory
  • The theory holds that the user has a defective or
    inadequate personality, so drug use is an attempt
    to escape the reality of a defective personality.
  • Because the person has an inadequate personality
    their peers reject them.
  • Drug use is a crutch that helps the person
    avoid the life problems caused by an inadequate
    personality (immaturity or lack of social
    skills).
  • Peer rejection causes the user to continue drug
    use and opens a new deviant peer group where the
    user can have intimate friends.

53
Psychological Theories (4)
  • Problem Behavior Proneness
  • The individual has a tendency to be
    unconventional and gravitates toward risk taking
    behavior.
  • Risk taking behavior exist on a low-to-high
    continuum
  • Moderate risk taking has been associated with
    inventors, scientists, etc.
  • Characterized by high levels of risk taking and a
    tendency toward life transition experiences.

54
Sociological Theories
  • Anomie Theory
  • Anomie exists, whenever there is a discrepancy (a
    block) between the socially approved goals for
    citizens and the socially approved methods of
    achieving those goals.
  • There are only five behavioral choices available
  • Conform - continue the approved method and
    potentially accept defeat.
  • Innovate - create a new method to achieve the
    socially approved goal.
  • Retreat reject the approved goal and the
    approved method and retreat within the self.
  • Ritual continue with the approved method of
    achievement while losing touch with the approved
    goal of the behavior.
  • Rebel create new goals and new methods for
    achievement and encourage others to follow.

55
Anomie Theory cont.
  • All people are faced with situations where our
    behavior does not lead to the desired goal.
  • The feeling of blocked achievement is anomie and
    each of us chooses all five behavioral choices
    depending on the given situation.
  • We may choose to conform in one instance and
    rebel in another. In the world of drug use, a
    retreatist response to anomie represents the drug
    user (and addict), and the drug dealer represents
    the innovative response.
  • The greater the feeling blockage for achievement
    in society, the greater the drug use.

56
Sociological Theories (2)
  • Social Control Theory
  • Given the natural state, all people would engage
    in deviant behavior.
  • What contains the deviant behavior is social
    control.
  • Most people do not engage in criminal behavior
    because of strong bonds with social institutions.
  • If the bonds are weak, we are released from
    societys rules and we are free to deviate.

57
Social Control Theory cont.
  • It is not the ties to the drug user world that
    causes drug use, but the lack of ties to the
    mainstream culture that frees them to use drugs.
  • The more attached we are to conventional society,
    the less likely we are to engage in behavior that
    violates the cultural norms for behavior.
  • The more attached we are to parents, teachers,
    clergy, employers, etc. the less likely we are to
    use drugs.

58
Sociological Theories (3)
  • Social Learning Theory
  • The use and abuse is the product of exposure to
    groups in which drug use is rewarded.
  • The groups provide the user (or non user) with
    social environments that generate definitions,
    role models, and social reinforcements for the
    use (or abstinence) of drugs.
  • By observing others in the group use the drug we
    learn how to act under the influence, how the
    group rewards the behavior (i.e. laughing), and
    how to define the experience (i.e. fun).

59
Social Learning Theory cont.
  • We learn drinking alcohol behavior by watching
    people we respect (role models) drink and seeing
    how they act while drinking,
  • Observing rewards others give the person for
    drinking.
  • Observing how to define the behavior of drinking.
  • The same process is in play with illegal drugs.
  • Differential exposure to drug using groups
    teaches the novice how to use and experience the
    use of the drug.

60
Sociological Theories (4)
  • Subculture Theory (Differential Association)
  • Involvement with a particular social group with
    attitudes favorable to drug use promotes drug
    use.
  • Involvement in a group with negative attitudes
    toward drug use tend to discourage drug use.
  • The characteristics of the individual count for
    nothing in the absence of social circles whose
    members explain use to the novice, supply the
    drug, and provide role models.

61
Subculture Theory (Differential Association)
cont.
  • The subculture theory holds that the use of the
    drug causes motives to continue the use.
  • The opposite of other theories that hold the
    individual motives lead to drug use.
  • Instead the person learns the necessary
    justifications and explanations that provide the
    motivations for further use.

62
Sociological Theories (5)
  • Selective Interaction Theory
  • People do not randomly fall into circles of drug
    users they are attracted to those groups because
    they share compatible norms and values with the
    drug users.
  • The more an adolescent is isolated from the
    parental group, the more involved they become
    with the peer subculture.
  • There is a competition among peers to attain
    status and prestige.
  • Higher status is granted in part as a consequence
    of engaging in activities and holding values that
    depart significantly from parental demands and
    expectations.

63
Selective Interaction Theory cont.
  • The theory predicts the follow sequence of drug
    use for adolescents.
  • The stages are a necessary, but not sufficient
    condition for the progression from lower to more
    serious drugs.
  • Stages of Adolescent Drug Use
  • 1. Beer and wine
  • 2. Cigarettes or liquor
  • 3. Marijuana
  • 4. Other illegal drugs

64
Sociological Theories (6)
  • Conflict Theory
  • Conflict theory applies exclusively to the heavy,
    chronic of drugs by members of a society.
  • The basic principle of the theory is that heavy
    use of drugs is strongly related to social class,
    income, power, and neighborhood.

65
Conflict Theory cont.
  • Four factors combine to promote drug abuse in
    communities
  • Poor economic opportunities, especially for
    unskilled labor.
  • Decreasing relative income of the neighborhood in
    comparison to other surrounding neighborhoods.
  • Community disorganization and general decline
    (denoted by neighborhood leaders becoming
    adversaries of city hall instead of allies).
  • A general sense of hopelessness and resignation
    among the people of the neighborhood.

66
Conflict Theory cont.
  • There is a pyramid of drug use, with many
    experimental users at the bottom, fewer
    occasional users in the middle and small number
    of heavy chronic users at the top.
  • Some members of all social classes abuse drugs,
    but those members at the bottom of the social
    class are more likely to do so.
  • To deny the basic fact of drug use patterns in
    America is to misunderstand one of the basic
    facts of human behavior social conditions
    influence human behavior.

67
The Extent of Drug Use
  • Two Dimensions Define Drug Use Legal Status and
    Goal
  • Legal Status
  • Some drugs are against the law
  • Use, possession, and sale is illegal
  • Some drugs are legal
  • Over-the-counter psychoactive drugs alcohol,
    etc.
  • Prescription drugs

68
The Extent of Drug Use (2)
  • The second dimension of drug use is
  • The Goal
  • Recreational use
  • The use of a drug as an end in itself
  • The goal is to get high, have fun, experience
  • Instrumental use
  • The use of the drug to achieve an end result
  • The goal is to achieve something socially
    acceptable

69
Types of Drug Use
  • LEGAL STATUS
  • Legal Illegal

Goal
Instrumental
Recreational
70
Legal Instrumental
  • Two Principle Forms
  • Over-the Counter
  • Tylenol
  • Sominex (sleeping pill)
  • Allerest (antihistamine)
  • Pharmaceutical (called legend drugs)
  • Many are psychoactive
  • Most do not stay confined to medical use
  • For example, in the 60s nasal inhalers became
    Speed Balls
  • Today Ritalin is sold on the street for
    instrumental and recreational use

71
Legal Recreational
  • Alcohol, tobacco, caffeine, Salvia divinorum
  • The drugs are consumed for a desired psychic
    state
  • Of course not every use, every time is
    necessarily for the buzz

72
Illegal Instrumental
  • Taking illegal drugs for some instrumental
    purpose that society approves
  • Includes taking drugs without a prescription
  • The goals vary
  • Drive the truck all night
  • Study for exam

73
Illegal Recreational
  • More money is spent on illegal drugs in the U.S.
    than anywhere else on earth
  • Americans consume 60 of the worlds illegal drugs
  • 80 of the illegal drug users in American
    consume marijuana
  • About 2 of Americans have used prescription
    drugs in an illicit manner (to get high)

74
Trends in Drug Use
  • Illicit drug use rose throughout the 70s
  • Illicit drug use peaked in the early 80s
  • There has been a significant decline in use
    throughout the late 80s and 90s
  • The one exception is marijuana use which began to
    rise in the mid 90s

75
Trends in Drug Use (2)
  • Attitudes about drug use have matched the use
    trends, however
  • Attitudes toward illegal drug use have generally
    become more favorable since the 90s
  • Has the trend toward more favorable attitudes
    continued?
  • What ever the answer drug use is vastly higher
    today than at anytime in the 1960s

76
Drug Death
  • Three drugs account for the majority of emergency
    room drug related admittance
  • Cocaine
  • Alcohol
  • Heroin/morphine

77
Drugs, Crime, and Violence
  • Crime refers to any behavior that has been
    formally prohibited by a political authority.
  • Criminal behavior is considered to be socially
    disruptive
  • Criminal behavior is too dangerous to be trusted
    to socialization alone for adequate prohibition.

78
Crime
  • There are three Basic Categories.
  • Street Crime - General crime committed by
    individuals.
  • Occupational Crime Job related crime committed
    by individuals.
  • Corporate Crime Crime committed by corporate
    organizations, not individuals.

79
Street Crime
  • Essentially entails the F.B.I.s list of the
    Eight Index Crimes
  • Murder
  • Aggravated Assault
  • Robbery
  • Burglary
  • Larceny
  • Auto Theft
  • Arson
  • Rape

80
Violence
  • Aggressive behavior that involves
  • Threat of Force
  • Force
