Examining Yoga's Effects on Smoking

The primary aim of this research study is to examine the effects of an 8-week yoga program on aspects related to nicotine dependence, stress, and coping during a smoking quit attempt. 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.
