Placebo-Males
Placebo - subjects will take one placebo capsule twice daily, orally (approximately 8am and 8pm) for twelve weeks starting seven days prior to the assigned quit date. They will also receive smoking cessation behavioral counseling.
|
Progesterone-Males
Progesterone - The progesterone will be given in the form of an active micronized natural progesterone (Prometrium). Subjects will take 200 mg twice daily, orally (approximately 8am and 8pm) for twelve weeks starting seven days prior to the assigned quit date. They will also receive smoking cessation behavioral counseling.
