Drug addiction

  • 1
    Subcutaneous administration of drugs
    Into large muscles
    Through mucous membranes
    Into fatty tissue
  • 2
    Drug tolerance
    Shift in dose response curve
    Feeling the effects of the drug less
  • 3
    Cross tolerance
    One drug can produce tolerance in another
    Being tolerant to a drug makes you tolerant to all drugs
  • 4
    Increasing sensitivity to drugs is known as
    Drug intolerance
    Drug sensitisation
    Drug desensitisation
  • 5
    Drug tolerance types
    Sensitisation and desensitisation
    Metabolic and functional
  • 6
    Metabolic tolerance
    NB other is functional tolerance
    Changes that reduce the amount of drug getting to the site of action
    Changes that reduce the reactivity of action sites
  • 7
    Individuals suffering withdrawal effects are
    Classed as drug addicts
    Tolerant to that particular drug
    Physically dependent
  • 8
    Two types of drug tolerance
    Contingent and Conditioned
    Sensitised and conditioned
  • 9
    Contingent drug tolerance
    Tolerance only occurs to drug effects that are actually experienced
    Tolerance maximally expressed when drug is taken in the same context
    NB other is conditioned tolerance
  • 10
    Tobacco heritability estimate
  • 11
    Alchohol heritability estimate
  • 12
    Individuals who no longer have drugs in their systems or withdrawal symptoms are said to be
    Diminished addicts
    Detoxified addicts
  • 13
    Which system moderates Intracranial self stimulation?
    Mesocorticolimbic dopamine system
    Mesotelencephalic dopamine system
  • 14
    Things associated with drug addiction
    Noreprinephrine and the nucleus accumbens
    Dopamine and Serotonin
    Nucleus accumbens and dopamine
  • 15
    Prefrontal cortex mediates
    Priming induced relapse
    Stress induced relapse
    Conditional cue induced relapse
  • 16
    Amygdala mediates
    Stress induced relapse
    Conditional cue induced relapse
    Priming induced relapse
  • 17
    Hypothalamus mediates
    Stress induced relapse
    Conditional cue induced relapse
    Priming induced relapse
  • 18
    Repeated cocaine exposure
    Facilitates LTP induction in serotinergic neurons
    Facilities LTP induction in VTA dopamine neurons
  • 19
    Which opiod receptor gene can stop alcoholism eh nalextone the opioid agonist?
  • 20
    Which gene is most common in people addicted to alcohol and cocaine?
    A1 allele of DrD2 receptor gene
    A2 allele of DRD2 receptor gene
