Title: Bupropion for Hospital-Based Smoking Cessation
Brief Summary: This is a randomized blinded trial of whether hospitalized smokers who are randomly assigned to receive bupropion, an antidepressant, and cognitive-behavioral counseling, are more likely to have quit smoking at the end of treatment and at 6 months compared with smokers randomly assigned to receive placebo and cognitive-behavioral counseling. Because depression is more prevalent among smokers and because smokers who are prone to depression may become depressed when they quit, the hypothesis is that the proportion of quitters who receive the active drug/antidepressant will be greater than the proportion of quitters who receive the placebo drug at 6 months.

Exclusion Criteria:

Subjects may not enter the trial if they:

1. have taken monoamine oxidase inhibitors, antidepressants, anti-anxiety agents, lithium, tryptophan or phenothiazines within the past month;
2. are being treated for hypertension with guanethidine, reserpine, thiazide diuretics, beta blockers, or clonidine;

Subjects with dysthymic disorder or anxiety disorders will be studied if their current symptoms are not sequelae of an episode of major depression. Excluding such cases would purify the sample by removing mild degrees of dysphoria, but would greatly restrict our ability to generalize any treatment implications to the current population that smokers.
