Study Details

Study Description

Brief Summary

The investigators 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

Condition or Disease Intervention/Treatment Phase
  • Drug: Low-dose Progesterone
  • Drug: High-dose Progesterone
Phase 2

Detailed Description

The sample population will consist of oral contraceptive users, both "low" and "high" dose levels of exogenous progesterone with a consistent dose of exogenous estrogen. Participants will complete 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 3-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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Low-Dose Contraceptive, then High-Dose

Females, 18-35 years old, non-pregnant, using oral contraceptive for at least the last 3 months before enrollment will be given Tri-Sprintec and generic Prometrium. Participants in this arm will begin with the "low" dose progesterone, which is seven days of placebo Tri-sprintec + placebo generic Prometrium twice daily (7AM and 7PM). Then participants in this arm will move to the "high" dose progesterone, which is seven days of placebo Tri-Sprintec + 200mg of generic Prometrium twice daily (7AM and 7PM).

Drug: Low-dose Progesterone
The "low" progesterone dose is seven days of placebo Tri-sprintec + placebo generic Prometrium twice a day (7AM and 7PM).

Drug: High-dose Progesterone
The "high" progesterone dose is seven days of placebo Tri-Sprintec + 200mg of generic Prometrium twice a day (7AM and 7PM).

Experimental: High-Dose Contraceptive, then Low-Dose

Females, 18-35 years old, non-pregnant, using oral contraceptive for at least the last 3 months before enrollment will be given Tri-Sprintec and generic Prometrium. Participants in this arm will begin with the "high" progesterone dose, which is seven days of placebo Tri-Sprintec + 200mg of generic Prometrium twice daily (7AM and 7PM). Then participants in this arm will move to the "low" dose progesterone, which is seven days of placebo Tri-sprintec + placebo generic Prometrium twice daily (7AM and 7PM).

Drug: Low-dose Progesterone
The "low" progesterone dose is seven days of placebo Tri-sprintec + placebo generic Prometrium twice a day (7AM and 7PM).

Drug: High-dose Progesterone
The "high" progesterone dose is seven days of placebo Tri-Sprintec + 200mg of generic Prometrium twice a day (7AM and 7PM).

Outcome Measures

Primary Outcome Measures

  1. Change in Smoking Urges [after overnight abstinence on day 8]

    Questionnaire on Smoking Urges-Brief (QSU-Brief): This ten-item version of the original form (QSU) was developed by Tiffany and Drobes and has an excellent level of reliability (α = .97). Total QSU-Brief. Scores can average between 1-7. A higher scores means more urges.

Secondary Outcome Measures

  1. Change in Positive and Negative Affect Scale Following Overnight Abstinence [after overnight abstinence on day 8]

    Positive and Negative Affect Scale (PANAS): Participants rate 20 words associated with positive or negative affect using a five-point Likert-type scale. This scale has been shown to have high internal consistency. Positive PANAS scores can range from 10-50. A higher score means greater positive affect. Negative PANAS score can range from 10-50. A higher score means greater negative affect.

  2. Change in Cohen Perceived Stress Scale [after overnight abstinence on day 8]

    Cohen Perceived Stress Scale (PSS): This ten-item questionnaire has been validated in a variety of populations including pregnant and postpartum women. It uses five-items to assess ten questions resulting in two factors negative feelings and inability to handle stress. It has high internal reliability (alpha = 0.75). Score range from 0-56. A higher score means more perceived stress.
