Smoking and lung function study
Part of Lungs & breathing clinical trials.
This study measures how well your lungs work and how much oxygen is in your blood. It compares smokers and non-smokers to see if smoking affects breathing.
Summary written for real people, not researchers, by Clin2.
Who can take part

This study looks for signs of long-term lung problems in people who smoke or used to smoke, while they are visiting a heart doctor. It uses a simple breathing test and a short questionnaire to check if they might have a condition called airflow limitation.
This study is developing a simple breathing test to check how tobacco, cannabis, cocaine, opioids, or alcohol may affect your lungs. It could help you understand your lung health and guide future care.
This study tests how cigarette addiction changes the speed and coordination of your legs. If you are a smoker or a non-smoker, researchers will compare your movement to see if smoking makes a difference.
This early-phase study looks at how smoking cannabis affects your lungs and breath. Researchers will check your breath for signs of inflammation and other changes, which may help understand how cannabis affects lung health.
This study tests whether a special health education program, along with a free lung scan, can help long-term smokers quit. You may be able to join if you are a current smoker between 50 and 80 years old and have never had lung cancer.
This study looks at lung function in people with early COPD (chronic obstructive pulmonary disease) to understand what happens over time. If you meet the lung test and health requirements, you may be able to help researchers learn how to better track and manage early COPD.
