Using two clinical models - pregnancy (Sample 1) and oral contraceptives (OC; Sample 2) - we
aim to (1) examine the association between levels of progesterone (Prog), allopregnanolone
(Allo) and the estradiol/progesterone (E2/P) ratios with smoking-related symptomatology
during ad libitum smoking, and (2) determine the association between Prog, Allo, and E2/P
with the changes in smoking-related symptomatology and response to nicotine following
overnight abstinence

Sample 1 will consist of pregnant women and Sample 2 will be oral contraceptive users.
Sample 2 will be testing "low" and "high" dose levels of exogenous progesterone with a
consistent dose of exogenous estrogen. All participants will complete identical data
collection procedures including providing saliva (cortisol to measure stress), urine
(cotinine and 3-Hydroxycotinine to measure nicotine exposure), and blood (progesterone,
allopregnanolone, and estradiol) samples, as well as ecological momentary assessments (EMA)
daily for seven-days. Participants will also complete a three-hour smoking topography lab
session after overnight abstinence and a 4.5 hour nicotine nasal spray lab session after a
14 hour abstinence. These sessions will contain a nicotine challenge via smoking a cigarette
or nasal spray with timed -series physiological, subjective and behavioral responses.
