Smoking relapse refers to the act of resuming smoking after a period of abstinence. Research in this area focuses on identifying the factors that contribute to relapse, understanding the psychological and physiological mechanisms involved, and developing effective interventions to prevent or reduce relapse rates. Some common factors that have been identified as predictors of smoking relapse include stress, social pressure, withdrawal symptoms, and negative mood. Interventions such as cognitive-behavioral therapy, pharmacotherapy, and motivational interviewing have been found to be effective in helping individuals maintain long-term abstinence from smoking. Overall, smoking relapse research aims to improve our understanding of the complex nature of addiction and develop strategies to support individuals in their efforts to quit smoking.
