Theories of Nicotine Addiction

Genetic influences 60% of initiation and maintenance of initial smoking

is driven by genetic influences

Bolus theory Based on body’s response to the bolus (ball) of

nicotine delivered to the brain

Adrenocorticotropic hormone (ACTH) theory Release of beta endorphins delivers euphoric effect

Self-medication theory Nicotine, through effects on dopamine, “lifts spirits”
