Summary

This study looks at how smoking impacts the ability to perform everyday activities in young adults aged 18-30 who smoke. Researchers will measure walking distance, sit-stand repetitions, and balance, along with feelings of breathlessness and fatigue. The goal is to spot early signs of reduced function before serious lung disease develops.
