The selection of a non-nicotine treatment is based on the acceptability of
various treatments with smokes, the ability to address the specific neurobi
ology of nicotine addiction, and the option to provide treatment for co-mor
bid conditions of nicotine-dependent patients. The search for effective tre
atments for nicotine dependence has generated a wide variety of non-nicotin
e approaches based on the neuropharmacologic and sensory basis for tobacco
use. The only non-nicotine, FDA-approved medication is bupropion, an amino-
ketone agent that is believed to work on the dopaminergic and noradrenergic
neurotransmitters involved in perpetuating nicotine dependence. This artic
