Psychopharmology
the branch of psychology that studies the effects of drugs on human cognition, emotions and behaviour
Psychoactive Drug
a substance that acts on the central nervous system and produces changes in a persons cognitions, emotions and behaviour
Intoxication
a temporary and reversible state induced by the intake of a psychoactive substance and characterized by disturbed cognition, emotion or behaviour
Tolerance
a condition caused by regular drug intake, whereby a higher dose is required to produce the same effects previously obtained with a lower dose
Withdrawal
a condition characterized by symptoms that emerge when a person who has developed tolerance to a drug abruptly stops taking it
Substance Use Disorders
a pattern of problematic psychoactive drug use that causes significant distress or impairment and is typically associated with impaired control over drug taking and harm to the user
4 Main Categories of Disorder Criteria
- Impaired Control
- Social Impairment
- Risky Use
- Pharmalogical
Factors Impacting Drug Effects
- Brain Reward Systems
- more intensely pleasurable drug experiences pose a greater risk of problematic drug use developing
- nature of the experience
Nature of the Experience is governed by
- drug type
- route of administration
- dosage size
- physical person attributes
- substance abuse history
- psychological explanations
- setting
Major Classes of Drugs
Stimulants
Depressants
Hallunicogens
Stimulants
a class of drugs that elevate aspects of our central nervous system functioning
- Cocaine
- Amphetamines
Depressants
a class of drugs that dampen certain aspects of our central nervous system functioning
- Alcohol
- Opioids
Hallucinogens
a class of drugs that are chemically unrelated but are all capable of producing hallucinations
- LSD
- PCP
- Cannabis
Goldstein’s Tripartite Model
describes the interconnections of drugs and violence
- Systemic Violence
- Economic Compulsive Violence
- Psychopharmacological Violence
Systemic Violence
a form of drug-related crime that occurs because the drug trade is illegal and it’s participants cannot turn to authorities for assistence
Three Dimensions of Systemic Violence
Organizational
Transaction
Third Party
Economic Compulsive Violence
a form of drug related crime that occurs as a result of drug users engaging in illegal behaviour as a means to support their habit
Types of Economic Compulsive Violence
- crimes committed to get money for purchasing drugs
- illegal commodities such as stolen property may be barred for drugs
- drugs may be stolen from dealers or other users
Psychopharmacological Violence
a form of drug-related crime that occurs as a result of the acute and chronic effect produced by psychoactive drugs
Relation between drugs and violence
Stimulants - violent behaviour
Depressants - most strongly associated with crime & violence
Hallucinogens - weakest relationship
3 categories of the Alcohol-Violence Relationship
Disinhibition Theories
Cognitive Disruptive Theories
Expectancy Theories
Disinhibition Theories
alcohol impairs areas of the brain responsible for inhibiting responses and as a result of intoxication behaviours normally suppressed are exhibited
Selective Disinhibition
a theory that the effect of alcohol disinhibiting violence depends on the perceived effectiveness of acting violently in the particular circumstances
Active Constraint
the relatively large conscious and deliberate effort needed to act in a socially acceptable manner in situations where acting violently is perceived to be an effective and desirable course of action
