    As the research progresses, the team will work diligently to gather a robust dataset from various sources, including wearable devices, lab sessions, medical-grade information, and detailed questionnaires. This comprehensive approach will enable the identification of specific biomarkers and hand-mouth gestures related to the different stages of tobacco use: pre-smoking, active smoking, and post-smoking. By analyzing these diverse data sources, the team aims to gain valuable insights into the physiological and behavioral patterns associated with each stage. This knowledge will not only enrich our understanding of tobacco use but also pave the way for developing targeted interventions and tailored support systems for individuals seeking to quit smoking. Through collaboration and innovative analysis, this research endeavors to create more effective strategies for smoking cessation, ultimately fostering healthier lifestyles.
