module 7 - final Flashcards
(102 cards)
1
Q
substance use
A
the ingestion with no negative effects
2
Q
substance intoxication
A
- experiencing the intended psychological effects of substances
- different depending on the substance, person, situation, amount of substance and method of engaging with the substance
3
Q
substance abuse
A
- when use causes distress and/or impairment
- distress to you
- impairing work, school, daily functioning or involve putting yourself in dangerous situations
4
Q
substance dependence
A
dependence is physiological and psychological
5
Q
substance dependence - physiology
A
- the physiological experience discusses tolerance and/or withdrawal associated with substance use
- increased tolerance: increasing amounts of the substance to experience an effect
- may not necessarily negatively affect you according to users
6
Q
substance dependence - psychology
A
- the beliefs and behaviours surrounding the substance
- the sense you are craving the substance
- beliefs you have about needing the substance
- behaviours you engage in; such as, are you engaging in negative behaviours to continue engaging in use?
7
Q
common misconceptions
A
- “Illegal drugs have no positive effects”
- “If you use an illegal drug once, you will become addicted”
- cannabis is a “gateway” drug
- prohibition increases drug availability
- only former drug abusers (those with addiction experience) make good drug therapists
8
Q
rat experiment
A
- rats in an empty cage were given regular water and water laced with drugs and majority/all of the rats drank themselves to death with laced water
- when rats were in a cage with stimulation (other rats, toys, things to do) none/minimal rats overdosed on the laced water
- proposed to idea that connections and bonding are adaptive and can contribute to a need for drugs
9
Q
substance abuse disorder criteria
A
- must meet 2/11 criteria over a 12 months period and experience significant impairment or distress
- the criteria are grouped based on:
- physical dependence
- risky use
- social problems
- impaired control
10
Q
etiology of general biological factors
A
- genetics: genetic contribution specific to alcohol, tobacco and opiates
- reward areas in the brain: dopamine reinforces use and is the most related system in the brain to substance use. our opiate systems consist of pain relief and pleasure
11
Q
treatment of general biological factors
A
- antagonists (block effects) exist to counteract overdose for some substances
- antagonist examples: naloxone → stop opioid (fentanyl) overdose and valium→ prevent amphetamine (cocaine) overdose
- stomach pumping → prevent alcohol overdose
- medically supervised withdrawal
- replacement medications such as methadone which can be legally prescribed as a replacement for the illicit drug
12
Q
general psychological etiological factors
A
- disease model
- parental influence
- expectancy effects
- positive reinforcement
- negative reinforcement
- opponent-process theory
- conditioned place preference/tolerance
13
Q
general psychological etiology - disease model
A
- addiction is the same as any other disease
- meaning if someone has access to the substance they cannot control their actions and will engage in said substance
- often taken by 12-step recovery approaches like AA
14
Q
general psychological etiology - parental influence
A
- if children grow up witnessing drug use in parents it will normalize it and may teach children that drugs are an appropriate coping mechanism
- on the other hand parents that exert firm behavioural control may stop the effects of negative peer influences
15
Q
general psychological etiology - expectancy effects
A
- how beneficial we believe the drug will be, increases our likelihood of using it
- expectancy effects are generally not linked to dependence but can be linked to abuse
16
Q
general psychological etiology - positive reinforcement
A
- e.g. the high from substances is positively reinforcing and can encourage more use
- poly-substance use is often an attempt to enhance the effects/the high
- e.g. partying with friends and getting high to have more fun
17
Q
general psychological etiology - negative reinforcement
A
- we remove the unpleasant to reinforce the behaviour
- removing either physiological or psychological distress reinforces use
- e.g. having a bad day and knowing smoking weed and feeling that high will make the bad feelings go away; escape bad things
- self medication motivation is less linked to abuse but more linked to dependence
18
Q
general psychological etiology - opponent-process theory
A
- we have emotions that are paired as opposites (happiness and sadness; fear and relief; pleasure and pain)
- this means that when you are experiencing one emotion the other is temporarily inhibited, and with repeated stimulus the initial emotion becomes weaker and the opposing emotion intensifies
- drug addiction is the result of an emotional pairing of pleasure and pain (withdrawal symptoms)
- drug users feel intense levels of pleasure but overtime pleasure decreases and withdrawal symptoms increase; meaning now they need more of the substance, more frequently to avoid withdrawal
- accounts for tolerance and reuse to escape withdrawal effects
19
Q
general psychological etiology - conditioned place preference/tolerance
A
- individuals develop context associations in reward related behaviours
- reward related behaviours can include both natural rewards and drugs of abuse
- when individuals engage in substances they may created associations with where they are and their use of substances
- e.g. if every time when they walk into their home, it is dark and they feel angry, go to their fridge and crack open a beer, it creates context cues
- your body will begin to ready itself physiologically or develop cravings when exposed to context cues
- can lead to overdose in certain circumstances if someone is consistently engaging in a substance in particular circumstances, their body will not be ready physiologically of you begin using a substance in a new area
20
Q
general psychological treatments
A
- 12 step programs
- support groups/community resources
- inpatient programs
- CBT
- motivational interviewing
- harm-reduction
21
Q
general psychological treatments - 12 step programs
A
- support disease model
- often a religious component tied to them
- often male dominated
- good for social support
- often not fans of independent research into their efficacy
- efficacy can range from 30-60%
- high drop-out rates
22
Q
general psychological treatments - support groups/community resources
A
- can help with things like housing and issues contributing to poor outcomes of addiction
- not effective in treating addiction
23
Q
general psychological treatments - inpatient programs
A
not super effective and are good for detox but that’s about it
24
Q
general psychological treatments - CBT
A
- more cognitive focussed
- exposure component of CBT is not as useful here
- can treat comorbid symptoms
- CBT typically more focused on controlled use rather then abstinence
25
general psychological treatments - motivational interviewing
- help individual find their own reasons for addressing their substance use
- used but itself or in conjunction with CBT
- tends to be fairly effective with addictions and teens
26
general psychological treatments - harm reduction
- focuses on helping the individual reach their goals and be safe about it
- can be use don combination with CBT
- research has shown effectiveness
- e.g. safe injection sites, providing fresh needles
27
substance related disorders
1. alcohol
2. tobacco
3. cannabis
4. amphetamines/cocaine
5. opioids
6. hallucinogens
7. gambling disorder
28
alcohol intoxication
- initial increase in well-being and decreased inhibitions
- increased use leads to decreased motor control, decreased coordination, impaired reaction times, poor judgment, blackouts
- long term, chronic use can lead to dementia and brain damage
- FASD is a potential side effect of alcohol consumption during pregnancy
29
alcohol withdrawal
- alcohol withdrawal for those with addiction may experience hand tremors, nausea, anxiety, insomnia, hallucinations and delirium tremens
- alcohol is the only substance where people can die from the withdrawal symptoms
- binge drinking men: 5+ drinks in 2 hours; 4+ drinks in 2 hours
30
delirium tremens
severe hallucinations and body tremors
31
alcohol disorder prevalence
- 12mo% = 12% men, 5% women
- higher in teenagers and young adults
- young males are most at risk of alcohol addiction
32
biological etiology of alcohol disorder
- genetics
- glutamate and GABA
- serotonin, dopamine and opioids
- alcohol dehydrogenase
33
genetics as an biological etiology of alcohol disorder
- genetic contribution particularly for men toward alcohol dependence
- individuals with a family history of alcohol addiction seem to experience more physiological pleasure from drinking
- heritability of alcoholism may be as high as 70% and its possible it is the same genes that predispose us to be antisocial
34
glutamate and GABA as biological etiology of alcohol disorder
- decrease glutamate which is a cause of blackouts
- increases GABA which has an anxiolytic effect and slows the firing of neurons
35
serotonin, dopamine and opioids as biological etiology of alcohol disorder
- increases serotonin but overtime/long term use depletes serotonin in the system
- the effects of serotonin are associated with cravings
- initial increase in dopamine and reinforces use or abuse but, long-term decrease in dopamine results in dependence
- hijacks our pleasure systems
36
alcohol dehydrogenase as an biological etiology of alcohol disorder
- dehydrogenase is the enzyme in the liver that breaks down alcohol and it is not present in some asian individuals which results in the skin flushing response; present in 30-50% of asians
- asians have lower rates of alcohol abuse
37
biological treatment of alcohol abuse disorder
- antabuse: causes nausea while drinking, but people often stop taking it if they know they will drink
- naltrexone: stops euphoria associated with alcohol by blocking opioid receptors
38
psychological etiology of alcohol disorders
- cultural differences
- alcohol myopia
- motivations for use
39
cultural differences as a psychological etiology for alcohol disorder
- affect perceptions of appropriate amounts of alcohol to drink, or the type of beverages more likely to be consumed
- some cultures and religions completely discourage alcohol use
- certain places such as France and Greece are more comfortable with childhood use of alcohol and actually have lower rates of alcohol abuse
40
alcohol myopia as a psychological etiology for alcohol disorder
- myopia refers to nearsightedness
- alcohol Myopia is the tendency of alcohol to increase a person's concentration upon immediate events (what's happening right now) and reduce awareness of events which are distant (less focus on the future)
- focus on here and now and defines YOLO
41
motivations for use as a psychological etiology for alcohol disorder
- are the engaging with alcohol for positive reinforcement reasons like the high or euphoria>
- are they using alcohol to medicate, and for negative reinforcement like removing pain?
42
psychological treatments for alcohol abuse disorder
- alcoholics anonymous
- CBT
- harm reduction
43
AA as a psychological treatments for alcohol abuse disorder
- support disease model
- “Turn yourself over to a higher power”
- promote complete abstinence
- huge dropout rates
- best features include lack of stigmatization and social support
- little research on efficacy because they tend to prevent research from occurring
44
CBT as a psychological treatments for alcohol abuse disorder
- focus on controlled drinking rather than complete abstinence
- examine their beliefs around how much they drink, what they think about their drinking, why they think they drink, when do they tend to drink, what triggers drinking, etc
- eeem to be equivalent if not superior to AA
- less dropout then AA but still has a lot of relapse (70-80%)
45
harm reduction as a psychological treatments for alcohol abuse disorder
- tailored to the individuals
- mitigate risks of their use through acknowledging contexts and environments where abuse occurs
46
amphetamines/cocaine intoxication
- initial increase in euphoria, alertness, insomnia
- with increased use you may experience hallucinations, anxiety, vomiting, weight loss, seizures, coma
- ages the brain quicker
- long-term negative side effects take a while to develop but sleep disturbances and social isolation tend to be the most prominent
47
amphetamines/cocaine withdrawal
experience apathy, boredom, depression, increased sleep, irritability
48
amphetamines/cocaine prevalence
- 12mo% = 0.2%
- use of cocaine is relatively uncommon, with less than 10% of people having ever used cocaine (don't memorize)
- no difference between men and women but men use cocaine more
49
biological etiology of amphetamines/cocaine abuse disorder
- increased norepinephrine and dopamine causes hallucinations
- reverse tolerance and sensitization
50
reverse tolerance/sensitization as a etiology of amphetamines/cocaine abuse disorder
- drug sensitization/reverse tolerance is the opposite of developing a tolerance to the substance, meaning you get increasing effects with the same use
- certain drugs, typically psychoactive substances, used repeatedly can alter the body's sensitivity so that repeated administration of the drug enhances its effects
51
biological treatment of amphetamines/cocaine abuse disorder
- propranolol: targets the anxiety associated with cocaine withdrawal
- modafinil & ADHD medication: give attention improving effects they'd usually get from cocaine without having to get high
52
psychological etiology of amphetamines/cocaine abuse disorder
- apathy and extreme boredom are symptoms of withdrawal which prompts re-use
- impulsivity linked to sensitization
53
psychological treatment of amphetamines/cocaine abuse disorder

55
CBT - contingency management -psychological treatment of amphetamines/cocaine abuse disorder
- behaviorism - positive reinforcement
- set up programs for the individual to receive positive rewards when meeting their goals
- e.g. read a paragraph get a gummy bear → but addiction model like 6 month clean chip
56
CBT - community reinforcement - psychological treatment of amphetamines/cocaine abuse disorder
- non-using social support in an individual's life being involved in their treatment
- improving relationships
- also helps with finding housing, work, education, recreational activities
57
harm reduction - psychological treatment of amphetamines/cocaine abuse disorder

60
tobacco/nicotine prevalence
- 12mo% = 15%
- 40% of people have been smokers at some point
- men tend to start sampling younger and rates of smoking in women tend to increase during the first year of university
61
biological etiology of tobacco/nicotine abuse
- nicotinic acetylcholine receptors: located in the limbic system, in the pleasure systems in the brain and smoking cigarettes enhances the influence of alcohol on dopamine
- genetic predisposition: heritability component of both depression and nicotine addiction
62
biological treatment of tobacco/nicotine abuse
- nicotine replacement therapy
- wellbutrin/zyban
- champix
- silver acetate
63
nicotine replacement therapy - biological treatment of tobacco/nicotine abuse

66
silver acetate - biological treatment of tobacco/nicotine abuse
- can be taken in the form of chewing gum or a lozenge
- makes tobacco taste bad
- not very effective
67
psychological etiology of tobacco/nicotine abuse
- depression/anxiety can prompt relapse if the most immediate effect of smoking is stress relief
- motivations for use
- environmental stimuli/triggers
68
psychological treatment of tobacco/nicotine abuse
- CBT:
- contingency management

- many people with opioid abuse will die from homicide, suicide or overdose
70
opioid withdrawal
experience nausea, chills, diarrhea, and insomnia
71
opioid prevalence
12mo% = 0.1-1%
72
biological etiology of opioid abuse
- enkephalin and endorphin systems are part of the general opioid system in our bodies which gets hijacked
- removal of pain is often why individuals keep using
73
biological treatment of opioid abuse
- methadone: switching someone's addiction to a legal drug
- buprenorphine: partial opioid agonist
- naltrexone: stop the high but rare for people to continue taking
74
psychological etiology of opioid abuse
- withdrawal symptoms prompt re-use
- sensation seekers vs. emotional copers
- sensation seekers use is motivated by positive reinforcement like the high or euphoria
- emotion copers use is motivated by negative reinforcement like removing pain

- 10-25% report trying it at some point
80
biological etiology of cannabis abuse disorder
- endocannabinoids
- sensitization
81
endocannabinoids - biological etiology of cannabis abuse disorder
- system throughout our brain and body
- effects of THC are wide ranging because of all the areas in our body with endocannabinoids
- contributed to slow reaction time, disrupt ability to remember recent events, effect judgment, cause anxiety
- effects the parts of the brain that gives you the feel good, euphoria, high feeling
- overtime THC can change how endocannabinoids work, which causes addiction, and long-term effects of memory
82
biological treatment for cannabis abuse disorder
treat comorbid conditions such as anxiety or depression
83
psychological etiology of cannabis abuse disorder
- motivations for use
- positive vs. negative reinforcement os use
84
psychological treatment of cannabis abuse disorder

- addiction is slightly higher in men
88
biological etiology of hallucinogens
- serotonin and norepinephrine (no idea how they are involved)
- there is no treatment
89
psychological etiology of hallucinogens
motivations for use
90
psychological treatment of hallucinogens
- rarely seek treatment most of the time they will just stop on their own
- CBT; similar to other addictions
- harm-reduction
91
gambling disorder
- persistent and recurrent problematic gambling behaviour, as indicated by:
- needs to gamble with increasing amounts to achieve desired level of excitement (tolerance)

100
emotionally vulnerable subtype of psychological etiology
emotional copers, the ones that gamble to hide emotional disorders
101
antisocial-impulsive subtype of psychological etiology
- genes that predispose someone being antisocial are also related to impulsiveness
- these would be the ones that don't make plans or may steal to pay for their gambling
102
psychological treatment for gambling disorder
- CBT/harm reduction: eliminate as many risks of gambling as possible while changing beliefs around chance, randomness and skills; also replacing gambling behaviour with a hobby or activity
- gamblers anonymous: rarely effective
