Addiction Flashcards
Describe the genetic explanation for maintenance of smoking
SLC6A3-9
Maintaining dopamine levels
Nicotine regulation model - changes in the brain functions avoid withdrawal symptoms
Describe the genetic explanation for smoking in relapse
Genetics
Tolerance - greater withdrawal
Physical dependency
Describe the learning explanation for smoking in relation to initiation
CC- association with social environments
OC- peer pressure (neg reinforcement)
SLT
Describe learning theory - smoking - maintenance
OC- rewarded stress relief approval from friends
Neg reinforced
SLT around smokers
CC - pos feeling and stress relief
Smoking relapse learning theory
Neg reinforcement -withdrawal symptoms
SLT- pressure to return
Cue reactivity paradigm - triggers
Cognitive smoking initiation
Expectations -stress reduction , attractive,weight loss
Coping attention focus
Concentration
Self efficacy
Relapse cognitive smoking
Expectancies
Coping
self efficacy

Describe the genetic explanation for initiation of smoking.
Genetics less likely SLC63-9
Dopamine
Smoking stimulates the D system in the Mesolimbic brain area. Feeling of pleasure
Inherit more sensitive Mesolimbic pathway

gambling - bio - initiation
genetic DA21 - increase sensitivity to dopamine - more likely to gamble
positive reward theory - anticipation- adrenaline
dopamine - increase psych levels create pleasure
