Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Guided by initial studies reporting on the effects of yoga on putative mediators of smoking relapse (i.e., cortisol, distress intolerance, withdrawal symptoms), the proposed experiment examines the effects of an 8-week yoga practice on nicotine withdrawal intensity by way of aiding withdrawal characteristics predictive of smoking relapse. The long-term objectives of the proposed line of research are to: (1) inform theoretical models of nicotine withdrawal, (2) guide the development of effective alternative interventions for smokers susceptible to relapse during the critical withdrawal period (i.e., smokers low in distress tolerance), and (3) to help guide behavioral strategies for treating substance addictions broadly.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Reducing nicotine withdrawal-related distress and relapse in low DT smokers may require the regulation of certain hormones involved in the hypothalamic pituitary axis (HPA-axis) (i.e., the human stress response). Regular practice of yoga, a mindfulness-based form of physical activity, emerges as a promising strategy for regulating the HPA-axis, decreasing withdrawal symptoms, and increasing DT, thus promoting smoking cessation success.
We will randomly assign 50 smokers (≥10 cigarettes daily) low in DT to either an 8-week yoga intervention \[YOGA\] or a waitlist control \[WL\] prior to undergoing a self-guided quit attempt. We hypothesize participants assigned to the yoga condition (relative to waitlist) will differ on various outcomes assessed throughout the intervention (e.g., quit status, negative affective states, stress, hormonal changes, withdrawal) and, quit day, and throughout the 2-week quit follow-up period.
More specifically, we hypothesize that certain typical maladaptive, during-withdrawal changes may be attenuated through YOGA. We also hope to obtain initial effect sizes of the advantage of yoga compared to waitlist for point-prevalent abstinence at two weeks following an unaided quit attempt.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Yoga
This will involve participating in at least two 60-minute Vinyasa yoga sessions each week for eight weeks (weeks 1-8). This will begin the week following a baseline laboratory appointment. These sessions will be conducted at a local Austin studio that has numerous locations in the area.
Yoga
The yoga intervention will be an 8-week program involving two 60-minute sessions each week at a local studio with three locations in Austin. Participants will be instructed to take classes deemed within a moderate-to-vigorous intensity dose. Participants will also be encouraged both by the PI and yoga instructors to complete the entire 60 minutes of yoga, urged to do only what is comfortable and not push themselves beyond their physical limits.
Waitlist
If randomized to this group, participants will complete weekly assessments only and not yoga during their time in the study. Following full completion of the study (i.e., after week 10), participants will be compensated with a voucher for 2 free months of yoga.
