Theories of
Nicotine Addiction

Genetic theory – 60% of addiction is
based upon genetic influence

Bolus theory – ball of nicotine reaches
brain, causing excitement


Adrenocorticotropic hormone theory
(ACTH) – release of beta endorphins
delivers euphoric effect
Self-Medication theory – nicotine via
dopamine “lifts spirits”

CNS



Smoking



Mainstream smoke = smoke
inhaled/exhaled by smoker (15%
exposure to non-smoker)
Sidestream = smoke from the
burning product (85% exposure to
non-smoker)
Environmental = smoke from either
method diluted by the air
Partners of smokers are 3 x’s higher for CAD and 30%
higher risk for lung cancer





Eclipse (cigarette that heats vs. burns
tobacco)
Accord (cigarette that reduces sidestream
smoke)
Advance, Omni, and Quest: cigarettes that
have ‘trionic” filters which reduce
carcinogen exposure
