Q

Drugs in the nineteenth century

A

In the 1800s,Medical advances succeeded in isolating active ingredients within many psychoactive substances.
E.g Morphine was identified as the major active ingredient in opium.
The invention of the syringe: Made it possible to deliver the morphine directly and quickly into the bloodstream.Psychoactive drugs were in widespread use
New drugs were developed with specific purposes or particular diseases. Anaesthetic drugs were discovered that made surgery painless.
some diseases could actually be prevented through the administration of vaccines, such as:
-Smallpox vaccine (introduced by Edward Jenner in 1796)
The vaccine against rabies (introduced by louis pasteur in 1885)
The discovery of new pharmaceutical products marked the modern era in the history of healing.

By the end of the century:
The risks of drugs dependence were beginning to be recognized
There was recognition that problems could result from the widespread and uncontrolled access to psychoactive drugs.

Q

Drugs and behaviour in the twentieth century : Opium

A

-Opium was cheap, easily available, and completely legal.
-Increased concern about the social effects of drug dependence led to:
Restrictive legislation regarding the use of morphine, heroin, cocaine, and marijuana.
Most people, from newborn infants to the elderly, in North America and Europe “took opium” during their lives.
-The way in which they took it, was a critical social factor
-The respectable way was to drink it, usually in a liquid form called LAUDANUM
-By contrast, the smoking of opium, as introduced by chinese immigrants. Smoking of opium was considered degrading and immoral.
In light of the tolerant attitude toward opium drinking.
-The strong emotional opposition to opium smoking may be viewed as more anti-chinese than anti-opium.
Laws prohibiting opium smoking began in 1908.

Q

Drugs and behaviour in the twentieth century : Alcohol

A

At the beginning of the 20th century, neither the general public nor the government considered alcohol a drug. However, in canada, prohibition started in 1901, when prince edward island banned all alcohol sales and consumption.
Prohibition:
Also succeeded in establishing a nationwide alcohol distribution network dominated by sophisticated criminal organizations.
Crime increased in major canadian cities as one group battled another for control of the liquor trade.
By the early 1920s most of the provinces had repealed prohibition.

Drugs and behaviour in the twentieth century after 1940 to 1970s

A

After 1945, important strides were made in the development of antibiotics and psychiatric drugs.
By the 1940s and 1950s, illicit drugs such as heroin, cocaine and marijuana were used outside the mainstream of life.
In the 1960s and 1970s:
The use of marijuana and hallucinogenic drugs spread across the nation.
-Along with an increase in problems related to heroin.
- Heroin abuse declined in the 1980s.
-Cocaine abuse increased with the emergence of crack as a cheap, smokeable form of cocaine.

Q

Present day attitudes toward drugs

A
  • It is now recognized that a wide range of psychoactive drugs, licit or illicit qualify as potential sources of misuse and abuse.
  • Individuals born toward the end of the “baby boom” generation were the first group to have grown up during the explosion of drug experimentation in the 1960s and 1970s.

The parents of teenagers at the beginning of the 21st century:
Face the difficult challenge of dealing with the present-day drug taking behavior of their children
Interestingly, there appears to be no relationship between prior marijuana use among parents and marijuana use by their children.

Q

Patterns of drug use in canada

The cross canada report on student alcohol and drug use (2011)

A

Patterns of drug use in canada
-The cross canada report on student alcohol and drug use (2011) collected data across provinces from students in grades 7,9,10 and 12. The exception was the province of quebec, which does not have grade 12. Focuses on five main areas.
Alcohol consumption during the past year, lifetime use and how often students consumed 5 or more drinks at a given time.
Cannabis consumption; during the past year, the past month, and daily use.
Use of illicit drugs (cocaine/crack, ecstasy, inhalants or steroids): over students’ lifetime.
Automobile-related alcohol use; whether they were passenger or driver
Automobile-related cannabis use; whether they were a passenger or driver

Findings
The use of alcohol was higher than cannabis and other illicit drugs, because it is readily available and relatively easy for students to acquire:
Alcohol use was reported at 52-70%
Cannabis use was 21-37% (the ranges vary depending on the province)
-19-30% of school students reported consuming five or more drinks in the past month
-12-20% of students in grade 12 had had at least one drink of alcohol and then driven a vehicle within the next hour.
-26-38% of students had been in a vehicle with a driver who had consumed alcohol, and 17-20% had been in a vehicle with a driver who had had too much to drink.
2-5% of students smoke marijuana on a daily basis
14-21% of grade 12 students had smoked marijuana and then operated an automobile within the hour
33% of grade 12 students had been in a vehicle that was operated by someone who had just smoked marijuana
4-7% of students reported lifetime use of ecstasy

Q

What is a dose-response curve?

A

An s-shaped graph showing the biological or behavioural response due to the specific concentration of a drug.

32
Q

Compared effective dose, lethal dose and toxic dose

A

Effective dose: Minimal dose of a particular drug necessary to produce the intended drug effect in a given percentage of the population.
Lethal dose: the minimal dose of a particular drug capable of producing death in a given percentage of the population studied (normally established based on animal studies)
Toxic dose: the minimal dose of a particular drug capable of producing toxicity in a given percentage of humans.

33
Q

Explain therapeutic index and margin of safety

A

Therapeutic index: the measure of a drugs relative safety for use. Computed as the ratio of the lethal dose or toxic dose for 50% of the population to the effective dose for 50% of the population
Margin of safety: the ratio of a lethal dose for 1% of the population of the effective dose for 99% of the population

34
Q

Judging drug toxicity from drug-related deaths

A

The number of people who die each year as a result of drinking alcohol or smoking tobacco, Far outnumbers the fatalities from abuse illicit drugs.
Chronic use of alcohol and tobacco (both legally available) cause by far the greatest adverse health effects

35
Q

Behavioural tolerance

A

Helps explains why a formerly drug-dependent individual is strongly advised to avoid the surroundings associated with his or her past drug-taking behaviour

36
Q

Physical and psychological dependence

A

A physical dependence: the compulsive drug-taking behaviour is tied to an avoidance of withdrawal symptoms
Psychological dependence: the drug taking is tied to a genuine craving for the drug, and its highly reinforcing effects of users on the body and mind.

37
Q

Substance use disorder

A

A diagnostic term used in the DSM-5 for clinical psychiatrists and other healthcare professionals to identify an individual with and significant problems that are associated with some form of drug taking behaviour

38
Q

Changes made to the DSM included two major changes involving the diagnosis of drug taking behaviour

A

Minimum of two criteria has been established for an individual to be identified as having a substance use disorder
DSM-5 now has set a severity-of-symptoms scale for this condition

39
Q

The severity of symptoms scale:

A
1. Mild level substance use disorder: 
The presence of two or three criteria
      2. A moderate level substance: 
  The presence of four of five criteria
      3. Severe level level of substance:  
The presence of six or more criteria.
40
Q

Criteria for substance dependence

A

Tolerance: either the substance has been taken in increasingly large doses to produce the desired effect or a diminished effect has been experienced over time from the same amount of the substance.
Withdrawal: Psychological or physiological symptoms arise when use is stopped or use has continued in order to relieve or avoid these symptoms
Unintentional use in excessive amounts: the substance is often taken in larger amounts or over a longer period of time than has been intended by the user.
Persistent intentions or efforts to cut down on substance use: There are frequent attempts to quit or reduce substance use and repeated failures (relapses) in doing so.
Preoccupation: a great deal of time is spent in behaviours that are necessary to obtain the substance, use the substance, or recover from its adverse effects.
Reduction in fulfilling important personal responsibilities: social, occupational or recreational obligations are not fully met or abandoned in order to engage in substance use. Examples include quitting a job or neglecting the care of a child.
Continuing substance use even though there are major substance-related social or health problems: Examples include continuance of cocaine use despite recognition of a cocaine-induced depression or continuance of drinking despite recognition that an ulcer condition would be made worse

41
Q

Criteria for substance abuse

A

Recurring failure to meet major role obligations at work, school, or home due to substance use: examples include repeated absenteeism at work, school suspension and expulsions or neglect of members of one’s household.
Recurrence of substance use in physically hazardous situations or circumstances: examples include driving while intoxicated or operating a machine while impaired by substance use.
Recurrent legal difficulties related to substance use: examples include arrests for disorderly conduct or other disruptive substance-related behaviours.
Continuing substance use even though the individual is aware of persistent social, occupational, psychological or physical problems that would result or be made more difficult by the use of the substance: examples include physical fights or spousal arguments related to substance use.

42
Q

Three different categories of violence

A

Pharmacological violence: violent acts committed while under the influence of a particular psychoactive drug, with the implication that the drug caused the violence to occur
Economically compulsive violence: violent acts are committed by a drug abuser to secure money to buy drugs
Systemic violence: Violence that arises from the traditionally aggressive patterns of behaviour within a network of illicit drug trafficking and distribution.

43
Q

How has canada responded to the social problems of drug-taking behaviour?
Governmental policy, regulation and laws

A

Until 1900, the canadian government’s attitude toward addictive behaviour was laissez-faire.
This meant there was little regulation or control

Prior to the 1900’s (twentieth century)
-Some movements were undertaken to ban alcoholic consumption
- But no movements to ban the wholesale use to opium, morphine, heroin, or cocaine
The only exception being the move to ban the smoking of opium (however, this was more an attitude directed toward chinese immigrants and their customs).

44
Q

Opium act (1908)

A

The opium act (1908) This law prohibited “the importation, manufacture and sale of opium for anything other than medicinal purposes” Severe punishment for breaking the law

45
Q

Opium and Drug act (1911)

A
  • Imposed harsher penalties

- Now included cocaine & morphine as illegal substances

46
Q

Proprietary or patent medicine act (1909)

A

Was the first law the regulate legal drugs in canada. Required food and drug manufacturers to list the amount of alcohol or habit forming drugs (opium) in their products, had to be listed on the label.
But the sale and the use of any of these substances were left unrestricted

47
Q

The food and drug act of 1920

A

Second major piece of legislation governing drugs in canada
Required the licensing of drugs
The government had to receive and approve a company’s request to manufacture and sell a drug; led to the Food and Drug regulations act in 1947. And a more stringent licensing procedure.

48
Q

Food and drug regulations act (1947)

A

Required a drug license ( a contract) that allows a company to: fabricate, package, label, distribute, import, wholesale or test a drug.

49
Q

The controlled and drugs and substances act (CDSA) (1997)

A

Passed by the chretien government to replace both the narcotic control act and the food and drug act. In canada current legislation
Controls the possession, production, selling and importation of drugs, their precursors and other substances

50
Q

Drug license and analogue

A

Drug license: a federal contract that allows a company to fabricate, package, label, distribute, import, wholesale, or test a new drug
Analogue: a descriptive term in the controlled drugs and substances act that refers to a substance that has a substantially similar chemical structure to a scheduled drug

51
Q

Three type of injections

A

Intravenous (IV) The drug is delivered into a vein without any intermediary tissue. Taking heroin this way takes 15 seconds. The effects of abused drugs delivered in the way, are often called mainlining.
Intramuscular (IM) the drug is delivered into a large muscle, usually in the upper arm or buttock, is absorbed into the bloodstream through the capillaries serving the muscle.
Subcutaneous (SUB-Q) a needle is inserted into the tissue just underneath the skin, it has the slowest adaptation time of all the injection techniques.

52
Q

Four basic ways to administer body into the body

A

Oral administration
Injection
Inhalation
Absorption through the skin or membrane

53
Q

Explain oral administration

A

ingesting a drug by mouth, digesting it and absorbing it into the bloodstream through the gastrointestinal tract is the most common and easiest way of taking a drug. The drug must be the right level of acid or else it might not dissolve properly in the stomach. The membrane separating the gastrointestinal tract from blood capillaries is made up of two layers of fat molecules, making it necessary for substances to be lipid-soluble or soluble in fats, in order to pass through it and into the bloodstream. If it survives the stomach, the drug can also proceed from the small intestine into the bloodstream. Although even after success it most pass through the liver for a screening process. Enzymes in the liver are capable of breaking down (metabolizing) the molecules structure of certain drugs, thus reducing the amount that eventually enter the bloodstream. This is referred as the first-pass metabolism, which plays an essential role protecting us from potentially toxic substances that might be ingested.

54
Q

Explain inhalation

A

Second simplest way of receiving a drug effect is to inhale it in some form of gaseous or vaporous state. Moves drug through the alveoli in the lungs into the bloodstream and from the bloodstream to the brain. Takes only five to eight seconds.

55
Q

Explain three ways of absorption

A

Of a drug through the skin or membranes dissolves into the bloodstream
Intranasal: into the nasal cavity, it adhere to thin mucous membranes and dissolve through the membranes into the bloodstream.
Sublingual: applied under the tongue.
Transdermal patch: a device attached to the skin; drug slowly delivered through the skin absorption.

56
Q

Explain synergism, potentiation, cross-tolerance, cross dependence, individual difference

A

Synergism: the property of a drug interaction in which the combination effect of two drugs exceeds the effects of either drug administered alone
Potentiation: the property of a synergistic drug interaction in which one drug combined with another drug produces an enhanced effect when one of the drugs alone would have had no effect
Cross-tolerance: tolerance, results from chronic use because one drug induces a tolerance effect with regards to a second drug that has not been used before
Cross dependence: one drug can be used to reduced the withdrawal symptoms following the discontinuance of another drug.
Individual differences: some characteristics that can play a definite role in the effect of a drug: weight, gender, ethnic background

Q

Hindbrain

A

The medulla lies at the point of the hindbrain. The coordinator of the basic life-support system in our body. Breathing, blood pressure, heart rate, digestion, and vomiting.The pons is also another structure in the hindbrain, this helps us with alertness, helps us when we sleep or when we are awake. Behind the pons and medulla is the cerebellum, important for structure for the maintenance of balance. (Alcohol)

59
Q

MIdbrain

A

Important for sensory and motor reflexes, as well as for the processing of pain information.

60
Q

Forebrain

A

Includes the hypothalamus and the limbic system. It is through these structures that we can carry out the motivational and emotional acts that ensure our survival. Feeding behaviour, drinking behaviour, and sexual behaviour controlled by the hypothalamus. The limbic system plays an important role in organizing emotional behaviour during times of stress.

61
Q

65
Q

Compare agonist and anagosit

A

Agonist: a substance facilitates synaptic transmission
Anagosit: a substance that decrease synaptic transmission

66
Q

three important issues need to be understood in looking at the physiological effect of drugs:

A
  1. The extent to which drugs pass from the bloodstream to the brain
  2. The extent to which tolerance effects occur
  3. The extent to which a drug influences neuronal activity
67
Q

the blood brain barrier

A

The blood-brain barrier: a specialized separation between the bloodstream and central nervous system that keeps toxins and large molecules out of the brain.

68
Q

Biochemical processes underlying drug tolerance

-Tolerance can be examined in terms of two types of physiological processes

A

One occurring in the liver and the other occuring in the neuron itself.

69
Q

metabolic (dispositional) tolerance
and
cellular (pharmacodynamic) tolerance

A

Metabolic (dispositional) tolerance: over repeated drug administration’s, processes that produce the drug’s biotransformation in the liver
Cellular ( pharmacodynamic) tolerance :
Changes that occur in the synapse of neurons themselves.

70
Q

Whar is in tobacco?

A

Nicotine: the primary psychoactive drug in tobacco products, it is toxic and dependence producing, the primary effect of nicotine is to stimulate the CNS receptor that are sensitive to acetylcholine.
Tar: sticky material found in particulate phase of tobacco smoke and other pollutant in the air
Carbon monoxide: an odourless, colourless and flavourless but toxic gas

71
Q

The titration hypothesis of nicotine dependence

A

The idea that smokers will adjust there smoking of cigarettes in such a way as to maintain a steady input of nicotine into the body.

72
Q

Cardiovascular disease four types

A

Tobacco smoking produces an increased risk of cardiovascular disease such as:
Coronary heart disease and stroke, lung cancer as well as other forms of cancer and respiratory diseases such as: Chronic bronchitis and emphysema.

  • Coronary heart disease: A disease that damages the heart as a result of a restriction of blood flow through coronary arteries
  • Arteriosclerosis: A disease in which blood flow is restricted because the walls of arteries harden and lose their elasticity.
  • Atherosclerosis: A disease in which blood flow is restricted because of the build up of fatty deposits inside arteries.
  • Ischemic stroke: A disease in which there is an interruption of or reduction in blood flow to the brain. -causes paralysis, sensory loss, cognitive deficits or causes a combination of neuropsychological effects
73
Q

Respiratory diseases three type

A
  • Chronic obstructivepulmonary disease: A group of diseases characterized by impaired breathing due to an abnormality in the air passages.
  • Chronic bronchitis: A respiratory disease involving inflammation of bronchial tissue following a build-up of excess mucus in air passages
  • Emphysema: An enlargement of air sacs in the lungs and adnormalities in the air sac walls, causing great difficulty in breathing.
74
Q

Cancers

A
