Nicotine Patch Pre-treatment for Smoking Cessation in PTSD

Smokers with PTSD will be randomly assigned to 1 of 2 pre-cessation patch therapy conditions (active patch versus placebo patch) for three weeks before a target quit-smoking date. All participants to will receive bupropion beginning 1 week prior to their quit day, given that they are medically eligible to be prescribed bupropion. All participants will receive a two session brief cognitive-behavioral therapy (CBT) session and will begin standard nicotine replacement therapy (NRT) on their quit day. PTSD symptoms, mood, and smoking craving will be carefully evaluated throughout the study using electronic diary assessments on personal digital assistants (PDA). Specifically, participants will carefully monitor their symptoms, mood, craving, and use of cigarettes using electronic diaries for one week prior to the pre-cessation period, during the 3-week pre-cessation treatment period, and 6 weeks post quit date. Since no previous study has examined factors associated with smoking abstinence following treatment among PTSD smokers10, predictors of treatment response will be examined. The study is designed to address the following items:

Specific Aim 1: To evaluate whether supplemental nicotine administration (i.e., pre-cessation treatment with nicotine patch and bupropion) will result in improved quit rates among smokers with PTSD.

Hypothesis 1.1 Supplemental nicotine administration during the pre-cessation period will result in improved quit rates in the first quit week over the placebo patch condition.

Specific Aim 2: To utilize electronic diary assessment of PTSD symptoms, mood, smoking craving, and smoking during baseline, pretreatment, and quit periods to evaluate potential mechanisms of how pretreatment with the nicotine patch may increase abstinence rates.

Hypothesis 2.1 Supplemental nicotine administration will decrease craving for cigarettes during the 2 week pretreatment period as compared to the placebo patch condition.
