A
  • Gender

  • the best predictor of alcohol abuse
  • inherit a predisposition
  • Sociodemographic factors
  • Lower SES and education, Aboriginal > non-Aboriginal
  • The damaging effects of alcohol abuse vary across ethnic groups in Canada, likely because of different cultural constraints and biological tolerance of alcohol

39
Q

Mechanisms of Overdose

1. Effective vs Toxic Dose (Primarily Physiological)

A

a. Tolerance to intoxicating effects to a drug and the lethal dose both increase over time
b. Tolerance builds more quickly
i. Over time the amount of drug necessary to produce the high gets closer and closer to the lethal dose level
ii. Neuroadaptation: brain changes that take place over time to compensate for presence of foreign chemicals

40
Q

Mechanisms of Overdose

2. Compensatory Conditioning (Primarily Psychological)

A

a. Over the course of conditioning, a CS may elicit physiological CRs that oppose the US (compensatory CRs). These CSs include contextual cues present during conditioning
b. This contributes to withdrawal symptoms as well as tolerance
c. Siegal et al. (1982) suggested that a failure to elicit such responses might play a part in drug overdose
i. Phase 1 – Conditioning Trials
1. Three groups of rats were heroin addicted over 30 days. Three conditions: same room, different room, and control
2. Same and different room groups got heroin every 2nd day, and a saline infusion on odd days. Saline and heroin were given in different rooms
ii. Phase 2 – Test Day
1. Same room group: got a double dose of heroin in the room where heroin was usually delivered
2. Different room Group: got a double dose of heroin in the room where they usually got saline.
3. Control group: never had heroin before, but got a double dose
iii. Results
1. Same room – 32% mortality
2. Different room – 64% mortality
3. Control – 100% mortality
iv. Note: CSs (cues) for drug use will also frequently trigger cravings and withdrawal symptoms

41
Q

-Factors that play a role in smoking in Canada

A
  • the prevalence of smoking among adults is higher among Aboriginal than non, regardless of whether they live in rural or urban environments
  • Smoking is becoming increasingly concentrated among the poorer and less well-educated segments of the population
42
Q

Phencyclidine (PCP)

A

Also known as Angel Dust.

-classified as a Deliriant

43
Q

Marijuana

A

Minor hallucinogen, THC,

44
Q

Hashish

A

Drug derived from the resin of the marijuana plant

45
Q

Inhalants

A

Substances that produce chemical vapors that are inhales for their psychoactive effect
-reinforcing through their effects on GABA and dopamine neurotransmitter systems

46
Q

Biological Perspectives

A
  • Neurotransmitters - domaine and the pleasure causing effects of drugs.
  • Serotonin plays a role in activating the brain’s pleasure system
  • endorphins
  • Brain’s reward centres (mesolimbic pathways, nucleus acumbens)

Genetic Factors - alcoholism runs in families, about 3 to 4 times more likely to develop

  • men are a mix of genetic and environmental and women is only environmental but not completely sure why
  • genes that determine the structures of dopamine receptors in the brain can be inherited
  • ability to rapidly metabolize alcohol
  • can influence the degree of reinforcement obtained from consuming drugs/alcohol
47
Q

Learning Perspective

A
  • believe they are largely learned and can be unlearned
  • Operant Conditioning - drug and alcohol use is reinforced such as social, approval, combat depression, anxiety and tension. It is learned, and can be unlearned
  • relief from tension (alcohol- negative reinforcement)
  • stimulants can be used to”self medicate” as they temporality alleviate feelings of depression and heighten mood
  • based on negative reinforcement and so is withdrawal
  • Cues may cause cravings (classical conditioning)
  • stimulus smokers
  • modeling (observational learning)
48
Q

Cognitive Perspectives

A
  • outcome expectancies, decisions making and substance abuse
  • positive attitudes towards to drug increases the use in frequency and quantity
  • weight the positive and negative outcomes when deciding
  • self-efficacy expectancies
  • thinking that it can help to accomplish a task, reduce stress, use in challenging situations
  • shunts criticism
  • does one slip cause people with substance abuse or dependence to go on binges?
    • abstinence violation effect (attribution to stable internal factors)
  • What you believe is what you get - self-fulfilling prophecy
    • Amount consumed is influenced by expectation of alcohol
    • actual alcohol content didn’t matter
49
Q

Psychodynamic Perspectives

A
  • oral-dependent personality since it is a oral behavior pattern, dependence, depression, all stem from oral fixation
  • smoking is the same
50
Q

Sociocultural Perspectives

A
  • Cultural and religious factors play a role in drug and alcohol consumption
  • church attendance
  • social settings, peers
51
Q

Pre-contemplation

A

No intention on changing behavior

52
Q

Contemplation

A

Aware a problem exists but no commitment to action

53
Q

Preparation

A

Intent on taking action to address the problem

54
Q

Action

A

Active modification of behavior

55
Q

Maintenance

A

Sustained change; new behavior replaces old

56
Q

Relapse

A

Fall back into old patterns of behavior

57
Q

Treatment - Biological Approaches

A
  • Detox - process of ridding the system of alcohol/drugs under supervised conditions in which withdrawal symptoms can be monitored
  • Disulfiram - discourages alcohol consumption because it produced the strong aversive effects of a hangover right away
  • Antidepressants - shown promise in reduction of craving of cocaine following withdrawal but fail to be consistent for relapse. Disulfiram (Antabuse) has demonstrated the most consistent effect
  • reduction of serotonin may underlie alcohol desires. Use serotonin re-uptake inhibitors show increases in alcohol use.
  • Nicotine replacement Therapy - the patch
  • methadne therapies - synthetic opiate, helps treat heroin addiction to avoid abstinence syndrome. Swapping one drug for another basically
  • Naloxone and naltrexone - blocks the high from heroin and alcohol/opiates but has poor long-term compliance
58
Q

Nonprofessional support groups

A

AA, NA, CA. Promote abstinence and provide members with an opportunity to discuss their feelings and experiences in a supportive group setting

59
Q

Residential approaches

A

Stay in hospital or therapeutic residence

60
Q

Psychodynamic approaches to treatment

A
  • problems are rooted in childhood experiences

- until underlying conflicts are resolved, the problems will continue

61
Q

Cognitive-Behavioral Treatment

A
  • self-control strategies - focuses on helping the users develop skills they can use to change their abusive behavior. Cues or stimuli (antecedent), the behaviors and the consequences (ABC)
  • Social skills training - develop skills to help in social situations that prompt substance use, fend off social pressure
  • cue exposure training
  • motivational enhancement therapy - help them realize that treatment is in their best interest, motivate them
62
Q

Relapse-Prevention Training

A 
• Pattern/high risk factor recognition 
• Predictability 
• Behaviours/thoughts/feelings 
• Chains of behavior/thoughts and feelings 
• Specific coping strategies 
• Escape/avoidance 
• Weekly “bring-backs” 
• SUDs 
• Abstinence Violation Effect
-controlled social drinking - controversial, drinking moderate amounts in a social setting rather than total abstinence
63
Q

Abstinence violation effect

A

Overreact to a lapse with feelings of guilt and a sense of resignation that may then trigger a full blown relapse

64
Q

Harm Reduction

A

• Whereas most interventions aim to reduce or eliminate substance use entirely, the Harm Reduction approach attempts to mitigate the harmful consequences.
– Needle exchange programs
– Methadone programs
– Designated drivers
– Restrict use to weekends or other non-workdays

65
Q

Other Addictive Disorders

A

problem gambling behaviour was considered an impulse control disorder in former editions of the DSM. In DSM-5, gambling disorder is classified with other substance sue disorders, Gambling disorder has commonalities in expression, causes, comorbidity, and treatment with substance use disorders

  • The broader category, though not formally mentioned in DSM is process addictions
  • partial exception is Internet Gaming Disorder (conditions for further study: in Appendix 3)
