Lesson 1 Flashcards
What are Drugs?
“A chemical substance that, when taken into the body, alters the structure or function of the body in some way.”
Is there a perfect definition to define what drugs are?
- There is NO perfect definition.
- The majority of definitions are not specific enough and leave important information out.
- Distinctions are often drawn in terms of whether the substance in question has been intended to be used primarily as a way to induce physiological change.
Why do we use drugs?
Drugs offer relief from an unwanted condition.
- ex. disease/illness, pain, stress, boredom, etc.
Tension Reduction Theory
Believe that one uses drugs to result in relief from tension and stress.
The more intense the stimulus is, the more intense the need to reduce it.
- ex. “I use drugs to calm down, to help me think less.”
Trauma Theories
Psychological damage as a result of a distressing event.
Stress lies outside of one’s ability to cope.
Two main theories:
- Trauma results in substance use.
- Substance use increases the chances of experiencing a trauma.
Self Medication
Drugs can be used to medicate psychiatric disorders and painful emotions.
- ex. cannabis is used for mood regulation by those with schizophrenia
Not good for the long term.
The Disease Model
- Substance dependency is seen as an illness beyond the control of individuals.
- Frames substance dependency to various medical causes.
- Theory that is advocated for by Alcoholics Anonymous.
- Foundation of 12 Step Programs.
Genetic Model
Addiction is developed as a result of the influence of both genetic and environmental factors.
How genetic factors contribute to individuals’ differences in substance use.
- Twin Studies
- Adoption Studies
Twin Studies
Studies that help assess genetic vs. environmental influences.
Involve examining the similarities and differences between identical (monozygotic) twins and fraternal (dizygotic) twins.
Twin Study Results
Based on the logic that since twins are born to the same parents at the same time, they are likely to experience very similar circumstances in terms of their family and upbringing.
Therefore, controlling for environmental effects to some degree.
- ex. both having alcoholism is more likely for identical (MZ) twins then for fraternal (DZ) twins.
Adoption Studies
Research studies that compare an adopted person’s behaviour to both their biological and adoptive parents’ behaviour.
Adoption Study Results
Found that the risk factor remains whether raised by biological or adopted parents if biological parents have an addiction.
- Supports genetics.
